dsixda's HTC Android Basic Kitchen - http://forum.xda-developers.com/showthread.php?t=633246
In my crazy quest to learn more about Android, I decided to create a companion to dsixda's kitchen that will take some of the drudgery out of downloading and compiling AOSP and the HTC kernel.
Here's what the current menus looks like:
Code:
Select the device that you would like to build for.
1) HTC Droid Eris
a) About Builder
0. Exit
Please enter option number:
and then
Code:
1. Sync AOSP - Cupcake (1.5) repo
2. Sync AOSP - Donut (1.6) repo
3. Sync AOSP - Eclair (2.1) repo
4. Sync AOSP - Froyo (2.2) repo
0. Exit
Please enter option number:
You can follow these two steps, and you will get a freshly compiled, but unsigned ROM in the original_update folder. After running it through the kitchen, it boots up just fine. Of course, most of the hardware doesn't work. That's the part that I am working on now (seriously, I am). I've been working on this for a while, because as I said - this is really about me learning. If I can make a tool that someone finds useful, then great!
Install instructions:
1) download and unzip dsixda's kitchen to whatever directory you want
2) download Android Builder into kitchen's scripts/plugins folder and unzip
3) back out and start the kitchen
4) select 'Run plugin scripts' from Advanced menu and select 'Android Builder'
5) you're there!
NOTE: This will try to install/update all of the packages that it needs, including Java5. Please look at the code so that you know what it's doing. That's just a good general practice with any code that you can actually look at and that you have to run as root...
Future plans:
1) add more kernels (devices)
2) add more vendor trees (goes along with devices)
3) add more repos (CM5, CM6, AOSP Master)
I hope someone finds this useful, and feel free to post useful suggestions/bug reports.

CHANGELOG -
v5. - kiel123 re-wrote v.4 as a plugin to dsixda's kitchen with me testing afterward, minor fixes, removed Java6 as no longer needed by kitchen
v.4 - re-wrote to add structure to support more devices in the future
added option for Cupcake, Donut, and Froyo
added .config files that enable touchscreen in kernel by default
v.3 - unreleased build
v.2 - corrected misspellings in code and dialogs
added sudo to launch setup script (Still need to sudo bash first. Sorry.)
v.1 - initial release
Very nice. I have been doing the same. I have used darchstar's post here as the basis of my work. But, I am always glad to look how others are doing things. Thanks for the post.

Thanks for the thanks! I don't quite get the vendor tree thing, but I just need to look at it again a few times. And, that's where I'm at. It would be really neat to be able create a working AOSP ROM from scratch with minimal manual intervention. It might not be possible, but I haven't found that out yet. (But wait! If you can do it manually, it can be scripted. Right?)
there's typo in your install script
look for line: android_builder*
should be android-builder*
and your install script should use mv command instead of cp to avoid files duplication
EDIT: also you should use sudo command along with ./ab_setup script or include within script as well.
When i ran ./abmenu and i get this message
Code:
Please copy 'menu-kd' to the root of your kitchen folder with 'menu'
menu-kd?.... don't you mean abmenu? turned out it was looking for menu file which i had it renamed to kitchen_menu but I fixed that on my part and all is working well.
Dont let any of my criticism scare you away, I can see there's a lot of potential use for this scripts, great start by the way.

I renamed all of the scripts at the last minute and thought that I had them fixed. I'll make the corrections and repost. The goal is to get this thing working well. Your criticism is just more motivation. Thanks!
I'm new to all this but I would love this to work with Froyo source.

The current 'internal' build works with Cupcake (1.5), Eclair (2.1), and Froyo (2.2). It's not ready to release though. Give me another week or two. I'm working on proprietary bits now, so that you get a more usable ROM from the start.
Although from your sig, it appears that you don't have an Eris, so you probably don't care much about it's proprietary bits. If you want it to get Froyo instead of Eclair, you can just change 'eclair' to 'froyo' in the script that creates the repo.
I'm with you on Froyo. I have a feeling in a month or two very few people will want to run a pre-Froyo ROM. It's really nice.
rm error on install
i keep getting "rm: cannot remove './bkup': No such file or directory"
the file is there untill i run the ./install script then it disappears and shoots me an error any help would be appriciated

That files was used by me while developing the code. It's not needed. I'll fix the install script for v.5, but if you really want to fix the script now... Just remove the line -
'rm ./bkup'
from the 'install' script
You should still be able to start Android Builder by typing './abmenu', as long as it's in the same folder with the kitchen's menu. The error shouldn't matter.

Good deal. Let me know how it goes.

Have you thought of making this into a .plugin file that can be placed in the scripts/plugins folder of the HTC Android Kitchen? Then that way you won't need to update your scripts each time I update my kitchen
In my thread I could provide a link to your tool, so that people can add that plugin if they want.

The thought has occurred to me.
Give me a bit. A link in your thread would be great. It might even motivate me to add more devices. Getting stuck on adding Eris proprietary bits has lead me down the road of making a ROM (http://forum.xda-developers.com/showthread.php?t=725447) and documenting the process. I'll get back to Android Builder soon though.
Ok, so...
TO-DO
-------
1) rewrite AB as a plugin to dsixda's HTC Android Kitchen
2) add proprietary bits for Eris
3) add more devices
4) add CM repos
5) add Gingerbread repo
6) add compatibility with more distros

Interesting... I've tested from a freshly installed Ubuntu installation several times. It should install everything you need.
You could try 'update-alternatives --config java' and let me know what it says. You could also look for a file called 'setup_ran' in the root of the Kitchen, and delete it. Start './abmenu' after that and try again.
thanks for answering. Could the problem be that i installed it on cygwin.

Yes. Android Builder will not work under cygwin. I don't know that it ever will. That's on the TO-DO list, but it's so far down that it's not on the posted TO-DO list.
I've only tested under Xubuntu 10.04 and minimal Ubuntu 10.04.
If you happen to work it out on cygwin, let me know! I'm sure others would be happy to have the option. Heck, I might even be. I'm mainly using Ubuntu because of AB anyway. (Although, it is kind of growing on me.)
thanks i will look in to it.

just wanted to let you know that it didn't work for me. It runs, gives some errors and outputs a update.zip called AOSPbase but the file is only 1.1kb in size.

make sure you have java5 and java6 jre/jdk installed. it should work then. i had a similar issue the first time through... took it literally 10hours plus, then output was the 1.1k AOSPBase.zip file.
manually installed all java components, and everything worked perfectly then (and took half the time)
Okay, I'm writing this because I want to help any other newbies trying to learn how to reverse engineer. The technical details involved in this are extremely daunting, so the purpose of this tutorial is to first explain in layman terms exactly what you're trying to accomplish and what to expect. Then we'll go over the details. That way you're not completely blind going into this. I'm fairly new to the scene, so I'm not as knowledgeable as everyone else. If you see any errors in my post, let me know so I can change. I'm going to assume you know a little bit of Java, can find your way around a computer, and know nothing about Android. The techniques used should work with other Android phones. For this tutorial I'm using Windows 7, Cygwin, and my stock (not rooted) EVO 4G mobile phone.
The FM tuner for the Evo is run by a Broadcom chip: BCM4329. This chip is pretty amazing in that it does wireless, bluetooth, and it has an FM receiver/transmitter. We're interested in the FM receiver / transmitter.
Now, all android phones are based on a Linux kernel. Basically they're Linux running computers. The Android operating system is then installed onto the linux system. Every app is then run off of Android.
Android is based on Java but it is not a Java system. It uses a virtual machine called Dalvik. Google did this to get around licensing issues with Sun Microsystems. So they pretty much invented their own machine language (called byte code) for the Java language. This makes things complicated for the reverse engineer because from what I've read, once Java is converted into this machine language or byte code, it can't be converted back.
So let's rehash.
If you were programming strictly in Java, you would see these extensions:
Java source code = .java
Compiled Java source code = Java byte code = .class
Compressed file to package your program = .jar (Java Archive)
But since you're programming in Android and Dalvik, you will see these:
Java source code = .java
Compiled Java source code = Dalvik byte code = .dex
Compressed file to package your program = .apk
(I haven't mentioned this, but HTC further Optimizes their .dex code)
Optimized Dalvik byte code = .odex
I'm writing all of these down because it's very easy to get confused with all of the extensions. (for me at least!). remember how I said once you go dex, you can't go back to java? That's where JesusFreke comes in. He's a senior member of XDA, and he created "baksmali" and "smali", two programs that can convert the Dalvik code back into a human readable format. These files have extensions of .smali
Decompiled Dalvik byte code = .smali
But what can you do with .smali files? That's where this other senior member, brut.all comes in: He developed apktool. apktool takes JesusFreke's work to the next level. This program in conjunction with NetBeans, actually lets you trace through any program using the .smali code taken from JesusFreke's programs!
apktool does this by converting those .smali files into "fake" .java files that can be used by the NetBeans (program that compiles and makes java programs) IDE. I say "fake" because apktool embeds the .smali code into java files as comments. However, once you attach a debugger to NetBeans, you'll see that the debugger will follow line by line every execution statement found in the smali code!
So...... you can take the program you want, plug it into Net Beans using a debugger (using the default ddms command provided by Android SDK), and you can trace everything you do in the program. I have it connected to my phone, so whenever I push a button while running my HTC FMRadio app or unplug my headphones,I see the corresponding response to the HTCFMRadio code I have loaded in NetBeans. I can now see in real-time how the program operates from my own interactions... JAM.
Technical Aspects: How to get from ground zero to tracing HTCFMRadio?
1.) Download Android SDK - Go to google development site and follow instructions: Make sure to download the latest Java JDK. Once that is installed, download NetBeans 6.8. Unfortunately, smali debugging does not work with the lastest versions of NetBeans.
Download the "Java SE" version for minimal space
http://netbeans.org/downloads/6.8/index.html
You can follow the rest of Google walkthrough and download Eclipse and ADT plugin, but it's not pertinent to this. You're going to be using adb and ddms from the android SDK extensively, so make sure the path for </android SDK/tools> is included in the PATH variable in your ENVIRONMENT SETTINGS. To get here, right click My computer, click properties, Advanced Settings, ENVIRONMENT SETTINGS.
2.) Search for 7z and download it. It is an awesome and free compression tool that will be extremely useful. It can be used to "unzip" .jar, .apk, and other compressed formats.
3.) Get the Radio app. You can do this by going to "shipped-roms" website, downloading the latest Supersonic image, and following the directions in the unlockr tutorial for HTC kitchens at the unlockr website... (once you have extracted the files from the image, you can look in the system/app and system/framework directories to get the files listed below) or:
you can pull the following files from your phone:
Using the command prompt type (and with phone plugged in, and with USB debugging enabled on phone):
adb pull /system/app/HtcFMRadio.odex
adb pull /system/app/HtcFMRadio.apk
adb pull /system/framework ./framework
This will put HtcFMRadio.odex and HtcFMRadio.apk in the current directory and create a framework directory with more files. A couple of the files in the framework are needed for the HtcFMRadio app, but for simplicity, we're just going to pull the whole directory.
Now that we have the files, we have to make a few changes to make the app installable and to be viewable by the debugger. To do this we have to decompile the .odex format into a human readable format we can edit. That brings us to:
3.) Download baksmali and smali from Project Hosting on Google Code (google search smali).
Usually an Android application is made up of one file, an apk file. Inside the apk file is an AndroidManifest.xml file, a classes.dex file (compiled Java code for the program), and other folders. The other folders contain either graphics or other .xml files that tell the program how it should look to the user. We don't have to worry about those for now. This is important because APKTOOL only opens programs set up this way. But wait up? We didn't download one .apk file, we downloaded an .apk file and an .odex file! What gives? Well, if you right click the apk file and open it (using 7z), you'll see that it's missing the classes.dex file. The dex file for the app is actually the HtcFMRadio.odex file we downloaded. So, to make this system app more like a nominal app, we have to find a way to convert the HtcFMRadio.odex to a classes.dex file. That's easy with baksmali and smali!
Once you download goto command prompt and type:
java -jar baksmali-<version>.jar -d framework -x HtcFMRadio.odex
(Remember to match baksmali-<version>.jar with the filename of baksmali you downloaded)
If done correctly, you should see a newly created \out directory
This creates an out\com\htc\fm directory with many .smali files.
Now let's reverse the process and put it back as a dex file. Type at command prompt:
java -jar smali-<version>.jar out -o classes.dex
If done correctly you'll see a newly created classes.dex.
now, right click on HtcFMRadio.apk (select 7z and open). Drag classes.dex into the file. Say yes to the prompt. Now you have a normal apk file APKTOOL can read!
4.) Download APKTOOL from Project Hosting on Google Code and the helper apps for your OS. (If you're extracting files for windows OS you should have apktool.bat and aapt.exe). Extract (again using 7z, don't you love this program?) apktool.jar (keep it as a jar file, don't extract the stuff inside of it), apktool.bat, and aapt.exe to the directory you're working on. To make things neat, you can also delete HtcFMRadio.odex (you don't need it anymore) and classes.dex (make sure you put it in the HtcFMRadio.apk file first!)
If this is the first time you're using apktool, then you have to install the htc framework so apktool can baksmali the Radio app. You only have to do this once:
apktool if ./framework/com.htc.resources.apk
Alright, at the command prompt:
apktool d -d HtcFMRadio.apk
This extracts the contents of HtcFMRadio.apk and places them in the HtcFMRadio directory. However, there are two major differences between this content and the content created in step 3. If you go into the smali directory you'll see that instead of .smali files, you'll see .java files. And if you go back and edit the AndroidManifest.xml file, you will also see that it's in text! Android applications convert their xml files to binary format. Now that APKTOOL has converted everything to an IDE friendly format, we can use NetBeans to edit everything. The first thing we're going to do is edit AndroidManifest.xml (using notepad) and add the following:
android:debuggable="true" to the Application tag.
IT should now look like this:
<application android:theme="@android:style/Theme.Black.NoTitleBar" android:label="@string/fm_app_name" android:icon="@drawable/fm_radio" android:taskAffinity="android.task.fmradio" android:description="@string/htc_corp" android:allowTaskReparenting="true" android:debuggable="true">
This permission lets the debugger watch the program while it's running on the phone.
We are going to run into two problems if we try to install this program. One is that Android doesn't let you install more than one copy of a system app. The second issue is that if we change the signature of our system app, then we'll have to change the signatures of our other system apps as well! Ahh.... So, to get around that, we're going to trick Android into thinking we have a completely new program. We're going to do that by renaming the com.htc.fm class to com.htc.modradio class. Next step:
5.) Cygwin (or Linux virtual machine)
The easiest way that I can think of to replace strings in multiple files is by using linux. You can most definitely do it in WIndows, but I dont know how. If you let me know how, I can put it in this tutorial.
(update: you can use Notepad++ to easily find/replace strings in multiple files for Windows. You still, however, want to download Cygwin if you're going to develop with Android-NDK.)
For now, just search for Cygwin (Cygwin is a program that lets you run Linux commands from a command prompt using your Windows directories), and install it. Make sure to have the Perl option selected. You'll need Perl to make the following commands work.
Once you get Cygwin up and running
cd <to your HtcFMRadio directory>
in my case it's
cd /cygdrive/c/Users/Jerry/Desktop/HtcFMRadio
now type the following commands in this order:
this command changes all occurances of htc/fm to htc/modradio in your xml and .java files.
find ./ -type f | xargs perl -pi -e 's/htc\/fm/htc\/modradio/g'
this command changes all occurances of htc.fm to htc.modradio
find ./ -type f | xargs perl -pi -e 's/htc.fm/htc.modradio/g'
If you don't follow this order, your source code will get messed up.
If using cygwin, a bunch of .bak files will be created. Using windows search, find all .bak files in your HtcFMRadio directory, then select them all and delete them (Make sure they are only files with .bak!)
Now just rename the fm directory to modradio. It is located in HtcFMRadio/smali/com/htc
Now go to your windows command prompt and type:
apktool b -d .\HtcFMRadio modradio.apk
Now sign and install modradio.apk on your phone.
adb install modradio.apk
If you have never signed before, then you need to use keytool and jarsigner. These two files are in your JDK directory, so make sure you include your JDK directory in the PATH variable of your ENVIRONMENT SETTINGS. (To get here, right click on My Computer, click Properties, Advanced Settings, Environment Variables. Once you make change, open up a new COMMAND prompt to see changes).
cd to the directory which has modradio.apk
now type:
keytool -genkeypair
Answer all questions, then use the same password for all password prompts.
Next type:
jarsigner -verbose modradio.apk mykey
Type in the password you created in the above step. Your apk should now be signed.
Next install:
adb install modradio.apk
Success!
6.) Testing the app on phone
Go to your phone and you'll now see a new FMRadio icon next to your first. Click on it and watch it open. It should now be able to play music. Keep it open.
7.) Using Netbeans
Go into HtcFMRadio and delete the build directory created by APKTOOL.
Now open up Net Beans and click on File, New Project, Select Java Project with Existing Sources, click on Next
Select HtcFMRadio directory for Project Folder, rename Project Name to whatever you want. Let's type in ModRadio. click on Next
Next to "Source Package Folders" click on "Add Folder" and select the smali directory.
Click Finish. For a quick tutorial by Brut.all, search APKTOOL in youtube and click on: Apktool Demo 2 - Smali improvements
Right click on Libraries. Click on "Add Jar / Folder". You want to add Android.Jar. Since I have Android 2.1 loaded I went to /platforms/android-7 located in my android SDK directory.
Your project is now ready for editting!
8.) Running the Debugger to trace through program.
Next go back to Windows command prompt and type ddms. This runs the Dalvik Debug Monitor. A window should open up. In the left hand side you should see com.htc.modradio. That's our app! To the right you're going to see 2 numbers, you're interested in the one to the right, 4 cells away from com.htc.modradio. This number is a port number, and you're going to use it to communicate with NetBeans. (In my case it is 8603)
Go back to NetBeans and click on Debug, Attach Debugger.
In the host field type: localhost
In the Port field: type in the second number you saw. (8603)
If everything is working you'll see a bug appear next to com.htc.modradio in the Dalvik Debug Monitor. Look at the bottom bar of NetBeans for feedback. If you get errors make sure the numbers match, or try port 8700 and make sure you select com.htc.modradio in the Dalvik Debug Monitor. Port 8700 is the default port used for whatever program you select in Dalvik Debug Monitor.
9.) Setting a breakpoint
I'm making this a seperate step because it is completely arbitrary. When creating a break point be sure to follow this rule:
You must select line with some instruction, you can't set breakpoint on lines starting with ".", ":" or "#".
Rather than looking for a spot to breakpoint, though, I'll tell you where to put one so you can quickly see how the debugger traces through the code. You aren't "REQUIRED" to do the next step, but if you want to trace you have to put a breakpoint somewhere.
In Net Beans click on the Project tab, click on Source Packages, com.htc.modradio, and then doubleclick on BroadcomFMTuner.java
We're going to insert a breakpoint. Scroll down to line 3226 and on your keyboard press: CTRL-SHIFT-F8, select line in dropdown box and hit ok. (To keep it simple, I usually look for "invoke" instructions to set breakpoints at)
Now go to your phone and click on the physical "back" button on your phone. This will clear the radio,(you should still be able to listen to music). Drag your status bar down. You should see a radio icon. Click on it again. The radio backgroudn will appear, but you wont' see any text or anything. Now go back to your netbeans application. You should now see debug options highlighted! Click on Step Over (F8) to step through!
nice tutorial
Nice tutor! I'm glad that finally someone is interested in smali debugging feature ;-)
About package name changing: I must warn you, that this isn't always that easy. It's advanced task, you must understand, what are you doing - otherwise you will get FCs for some apps and you won't know, why. And you don't have to change Java classes package name, so actually changing com.example.android should be enough - there is no need for changing com/example/android and dir names.
And I have few words about the background/theory: dexes, smali, (de)compiling, etc., but I will write them tomorrow
So I don't have to change the directory names for all of the invokes? Which means I don't have to rename the directory either? That sounds much easier. So you're saying to only replace the name in the application tag in the AndroidManifest.xml file?
Wow I'm a noob
Your badass tutorial just made me realize how much further I have to go. Great work!
BTW, if someone could figure how to make use of the FM transmitter and create an FM modulation app I think that could be popular. Not everyone has cars with input jacks and I know I really could of made use of it for my vacation I just took.
Once you understand how the software interacts with the Broadcom chip it shouldn't take too much should it? I would envision something working just like wifi tether does. No need to turn on the radio, the app just takes control.
Cool! Thanks! Will this work with eclipse also?

According to Brut.all, no.
"Google smali debugging - you'll find an article written by Brut.all"
Eclipse can open the files, but certain workarounds have to be done to get the same tracing to work.
A FM Transmitter that is able to transmit audio to a receiver without any addition cords hardware etc would IMO make the EVO 4G Un-Stoppable!!! I'll donate to support the dev/s in this effort
Will this get FM Radio working on any android phone with that broadcom chip?
Wow, great tutorial. I was looking for the hitch-hackers guide to my new galaxy and I think I found it. Cheers
Thanks this is great. I almost got it 100% working. But there's one problem. I'm debugging some other apk. And I can't set any breakpoints because, since the apktool made fake java files, all the code is comments, so there's no place to set any breakpoints since there's no real executable code!
Help how to get around this?
At the beginning of a class I tried to add something like... int a=0; while keeping the same amount of lines... just before comment start...
Code:
package com.example.app; class MainActivity {
int a = 0; /*
.class public Lcom/example/app/MainActivity;
.super Landroid/app/Activity;
.source "MainActivity.java"
and put a breakpoint there, but it still says its not an executable location.
Any ideas? This is cool and I'm so close with your great tutorial. Thanks!

I tried to use Eclipse, but seems it forbids to add breakpoint on unknown (commented out) line :-/ I workarounded this and added breakpoint, then I was able to debug normally, but you should treat apktool debuging as unworkable on Eclipse - at least until someone will find some solution.

Unfortunately not.
Refer to IntersectRaven's posts regarding enabling the FM Tuner for the Nexus One. He needed to create drivers for a custom Linux kernel to be used with a Desire ROM.
Smali debugging is important, however, because it allows developers to learn the code that implements the "undocumented" hardware for their phone (in this case, HTC phones with a working FM Radio app).

Thanks this is great. I almost got it 100% working. But there's one problem. I'm debugging some other apk. And I can't set any breakpoints because, since the apktool made fake java files, all the code is comments, so there's no place to set any breakpoints since there's no real executable code!
Help how to get around this?
At the beginning of a class I tried to add something like... int a=0; while keeping the same amount of lines... just before comment start...
Code:
package com.example.app; class MainActivity {
int a = 0; /*
.class public Lcom/example/app/MainActivity;
.super Landroid/app/Activity;
.source "MainActivity.java"
and put a breakpoint there, but it still says its not an executable location.
Any ideas? This is cool and I'm so close with your great tutorial. Thanks!

if you're using NetBeans, just keep trying to insert breakpoints at every "invoke" type statement.
A really interesting thread. Thanks for sharing your knowledge with us. A topic like this should have its own Forum like ‘Android Engineering Tutorial’. We need more tutorials like this one!
Bluetooth Driver Files released by HTC!
Just went to
http://developer.htc.com/
Bluetooth driver files released! We should be able to better control the radio now.
Any progress? I'll donate to the first person who gets an app to broadcast my music to my radio.

@midnjerry,
sorry if this is way off topic, but it does deal with the fundamental aspects that you have established here.
Can I use this method to reverse engineer the Google Voice app, so that I can have the same program installed twice for my two different Google voice accounts?
I just want to name the application something else, so that I can install it twice with two different sign in names.

Yeah, I think you can do that. Just change package name of an app to something else.

Can I do that in Eclipse or do I need to use need to use Smali Debugging? Just asking because I am not looking to debug the program only install it twice.
Hi,
I am currently trying to get into Android Developing and I am following a tutorial book called "Practical Android Projects" however, I have only got so far and I am coming across a problem.
I have installed the Android SDK and required files, and installed ant as per instructions here: http://ant.apache.org/manual/install.html (Under Windows and OS/2 section)
I am getting an error about my /res folder not existing, when it infact does exist, in the directory it specifies?
Please see screenshot at the following link: http://server3.uploadit.org/files/StuMcBill-cmdprompt.jpg
Thanks for any help you can give?
I am running Windows 7 Home Premium x64!

I would suggest using eclipse. Especially for beginners it is alot easier than building everything on console.
It has nice plugins and the android emulator from the sdk is integrated.
100% agree with Dark3n.
Ant is a programming language in and of itself. (Well sort of a scripting language but whatever).
No need to try and learn two things at once. I'd suggest wait until your 2nd or 3rd app at least to learn Ant. You really don't need it unless you want to use something like ProGuard. (Which is yet another thing to learn and another thing I'd suggest waiting on).
Oh an for a possible quick fix type
>ant clean
And see if that helps.
EDIT:
Err nevermind -- looked at your screenshot... why are you running ant from the System32 directory? Is your Android project really in that folder?
Usually you set the path environment variable in your system properties in windows to add ant to the list of paths, so you can run ant from any folder.
Then you can open that folder, type cmd in the address bar and open a command prompt in your project directory. You then run ant from there which reads the build.xml file an default.properties and local.properties files in your android project folder.
OK, I will give eclipse a try.
RE system32 and ant: Well the book I am following said to use ant, and I just followed the instructions and it installed the project in System32.
Could I just substitute Eclipse for ant while following the guide?
I do have Ubuntu installed on this computer, would that be better / easier?
Eclipse is available for any OS.
Use the one you are most comftable with.
I think eclipse might even use ANT internally but you don't have to hassle with it.
Working in system32 is not adviseable, you should generally keep out of there .
[UPDATE]
BusyBox 1.19.2
Bash 4.2
Midnight Commander 4.8
TMUX 1.5 - That's right, full terminal multiplexer..
Vim 7.3
Terminal IDE ASCII Soft keyboard first round bug fixes complete.
It's the addition of TMUX and MC that really excites..
--------------------------
Well,
As the only people I know who might even be interested in this, I would like to announce the release of Terminal IDE v1.0.
A complete Java / Android Development Environment that runs on the device itself, with a nice telnetd / sshd feature.
For Android. Of course... Eat this you IPhone Hounds..
Woo HOO!!
The application is available on Android Market.
https://market.android.com/details?id=com.spartacusrex.spartacuside
As what I can only describe as 'dark days' finally draw to an end, I am very pleased with this first draft.
PLEASE give it a go, log in over telnet for a smoother ride, and let me know how it goes..
DO THE TUTORIAL! Does it work ?!
I have released the whole project GPLv2! Yeah, Who Knew!?
http://code.google.com/p/terminal-ide/
BOOOOOM!
Spartacus
a link to the app in the market would be usefull.
Interesting. Was just wondering about coding on my tablet.
Pretty freakin sweet
Thanks for putting this out!
Awesome
The full keyboard alone makes it worth downloading, but the IDE as well - wow!
this is best bro.
I randomly found this last night while looking for a decent mobile IDE for my tablet. I was looking for a simple text editor with syntax highlighting and you've taken that extra step to include other tools for ssh, telnet and compilers. Much appreciated.
One question, how do you start the ssh server? sshd doesn't seem to do it. I would like to scp files to my device from my desktop in order to work on my commute.
Thanks
The sshd app is actually called Dropbear.
You also have Dropbearkey.
You use Dropbearkey to generate the sshd certificates you need.
I really need to add a tutorial on setting the sshd keys up
For now Google has a couple of articles on it.
For file transfers you also have busybox FTP but I admit not terribley secure..
Allthough SSH is provided, and I wonder whether an SSH pipe can be created..?
And lastly you can just copy the files over to your sdcard via USB..
Will look into it & add tutorials asap.
Ok. So I now have SSHD working..
But there is a slight issue.. basically when you log in you have to start bash manually.. unless you have the file /etc/shell with the correct shell to use.. Which requires a rooted phone.
Since Terminal IDE is for non-ROOT users, I will have to recompile the code to allow a shell to be specified on the command line.. Soon..
FOR NOW - This is how to connect to the phone via SSH (There are other ways using public keys but this is one way)
So - Once in Terminal IDE
2) You need to create a couple of server ssh keys
Start in $HOME
Code:
cd ~
Create folder
Code:
mkdir .ssh
Give it some secure permissions
Code:
chmod 700 .ssh
Get in there
Code:
cd .ssh
Now create the keys
Code:
dropbearkey -t dss -f dropbear_dss_host_key
dropbearkey -t rsa -f dropbear_rsa_host_key
ok - That's almost it. Just need to start dropbear with the correct parameters now. [Probably want to keep this in a script]
Back HOME
Code:
cd ~
You need to know the UID of your app, which is different per phone - use 'id'
Code:
id
That will tell you your user ID / Group ID. Let's say its 10058.
Now to start DropBear
Code:
dropbear -A -N username -U 10058 -G 10058 -C password -d ~/.ssh/dropbear_dss_host_key -r ~/.ssh/dropbear_rsa_host_key -F -E -p 8090 -P PidFile
This will start it running in the foreground with password set to 'password' on port 8090.
Then you can connect, like telnet, and simply use 'password' for the password.
Now for the issue. It will start a simple shell session in / with no ENVIRONMENT variables or anything..
I'll fix it permanently in a future release, but for now it can be fixed with these 2 commands.
cd into your home dir - Check this is correct on your device
Code:
cd /data/data/com.spartacusrex.spartacuside/files
And start bash with an init file Terminal IDE auto-magically creates..
Code:
./system/bin/bash --init-file ./.init
Everything should now be setup as usual.
Good luck..
Very awesome and thank you sir. Works like a charm.
One thing to clarify for those "braving" this (not that it's all that insane to try)... the '-N' is setting the username (in the case of the example, setting it to 'username').
Also, it gives a permission denied for scp, I'm assuming since it doesn't init/run the shell. Should be fine since FTP is included. Haven't tried this option yet. Not too worried about security at the moment, since I'll only run it on a private network.
May I make a (maybe) small feature request? Is it possible to include a "keep screen awake" option in the options menu? I have my Xoom config'd to turn off the wifi when the screen is off for power saving (can go ~4 days on 1 charge), so it will kill my connections if I let this happen. I know not everyone has this config set, but it'd be a nice option.
NOW, if I wasn't lazy, I could probably add this myself and build since I've dl'd the source. But, lazy and working on a few projects already.
Again, much thanks.
And as if by magic..
Funnily enough I was having the exact same issue last night while using wget to transfer a big file to my device..
NEW VERSION UPLOADED v1.13
Now has 3 non-exclusive lock types available in the options :
- CPU Lock
- SCREEN Lock
- WIFI Lock
Set them as you wish...
Saw that this morning when I was on the bus (Thursday morning here in Hong Kong). Very awesome and much appreciated.
As well, thanks for open-sourcing it. +1 for you sir!
Very cool stuff
Thanks for creating this.
Great app! However I can't compile .java files. I always get an error that it can't unzip a file in /android.policy.jar. Any idea?

Do you think its possible to also support compiling C sources directly in your phone

THANK YOU.

Most likely seems to be due to the ROM you are using and/or the market version
can u post the build.prop here?
/system/build.prop
also, try going back to market 2.x, 3.x market(s) do loads of checks
Does anybody know why I can't compile java files? I always get the following error:
Error reading /system/framework/android_policy.jar cannot read zip file.
Any ideas? Could anyone upload there android_policy.jar because that might cause the error.

Hi Schindler33.
Can I ask, have you followed the tutorials, say the first helloworld example TO THE LETTER?
Does the helloworld example work?
The parameters have to be correct, and as always exact, and the BOOTCLASSPATH variable must be set.
If so, is it a custom ROM?
Does that policy jar file exist and is it readable by non root users?
As much info as possible good..
I have a Nook Simple Touch, BNRV300, and I have successfully modified uRamdisk to gain root shell access with ADB over USB (Thanks Renate!). I am currently on firmware version 1.2.1.
I know this may seem like heresy to some here, but I really do not want or need to root my NST and add a number of apps I won't use anyway. I have a fully rooted Nexus 7 for that sort of thing.
All I would like to be able to do is turn off the need to swipe to unlock when returning from sleep, and modify the text on the screensaver overlay.
I have discovered, by the way, that sqlite3 does not seem to be available on this NST, as when trying to use it via ADB shell, it says "sqlite3: not found".
SO, there we are... I would greatly appreciate any assistance offered.
MildBill
P.S. I have tried Nook Manager, and while it did what I wanted, there were many things added that I just have no need for. And, battery drain seemed to double.So, it had to go.
Regarding SQLite3.
Since the guts of it (libsqlite.so) is already in the Nook, you only need the command line executable (sqlite3).
It's here: http://forum.xda-developers.com/showthread.php?p=50958855#post50958855
Unzip it, stick it in /system/bin, chmod 755 it.

Ahh, once again, thank you Renate. Now if I can get some idea on my main questions...
There are no simple questions here. Even the answers are complicated.
Many people have created solutions and packed them into these "manager" things.
I finally got around to doing my own minimal one.
It's packaged up in nook121patch.zip (in the signature).
Code:
C:\>adb pull /system/framework/android.policy.jar
C:\>apktool d android.policy.jar \AP
C:\>mergesmali /v C:\AP\smali C:\Nook121Patch\KeyguardViewMediator.smali
C:\>apktool b C:\AP android.policy.jar
C:\>adb shell stop
C:\>adb mount -o rw,remount /dev/block/mmcblk0p5 /system
C:\>adb push android.policy.jar /system/framework/
C:\>adb shell chmod 644 /system/framework/android.policy.jar
C:\>adb shell reboot

Well Renate, I hate to complicate your answer any more than necessary, but...
On the Temblast page that clicking on your signature takes me to, I do see mergesmali, one of the two tools I will need based on the instructions you gave. I do not see nook121patch.zip, nor apktool, however. Where can I find these?
Also, can you tell me something about what this will do for me?
I hate to be such a noob, I have just enough knowledge to be dangerous. Thanks again for all your help, sorry I have to keep asking for more.
MildBill
Well, I wasn't that clear.
mergesmali is in the signature, nook121patch.zip is on the mergesmali project page too.
Apktool is detailed and linked here: http://forum.xda-developers.com/wiki/Apktool
There are many patches in the nook121patch.zip
You can apply them selectively.
.jar is easy, they don't need signing.
.apk is trickier they must be signed.
System .apk is even trickier, they must be signed with the system signature.
The KeyguardViewMediator.smali will make that your Nook just opens with a push of the power button and no swipe.

OK so far, and (I think) I have apktool properly installed, then realized I also needed to install the Java Development Kit as well to use it, which I managed to do. But, when I try to do
Code:
C:\>apktool d android.policy.jar \AP
I get
Code:
Input file (\AP) was not found or was not readable.
as a response.
So, I guess I need to return to the magic well of your knowledge for further assistance and/or instruction.
To which I can only add...
HELP!
EDIT: By the way, I am using an adb.exe implementation from another root kit I have installed, not the standard installation from the SDK. Is this perhaps part of my problem?
Well, something goofy is going on there.
Type just apktool and get the usage and version.
\AP in this case is the destination directory.
It should not already exist or else you get a warning.
Maybe the input file (the jar) can't be found, but the error message is wrong?
Code:
C:\>apktool
Apktool v1.5.2 - a tool for reengineering Android apk files

Well, there ya go... I got apktool v2.0.0b9.
I can get 1.5.2, but will it work with Java 7? Oh well, live and learn I guess...
MildBill
Oh, well, then the 2.0 probably uses different args.
"apktool" by itself will tell you the order of arguments.
To run anything on the desktop the Java 7 runtime environment is fine.
To compile an Android application you have to use Java 6.0 SDK.

Well then, since it appears from the changes that 2.0 requires the Java 7 SDK, I guess I'll uninstall it all and get 1.5.2 and Java 6.
I'm running desktop applications:
Code:
C:\>java.exe -version
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) Client VM (build 21.0-b17, mixed mode, sharing)
I'm compiling Android applications with:
Code:
C:\>javac.exe -version
javac 1.6.0_38-ea
apktool runs under the JRE, version 1.7 is fine.
OK, finally got around to completing the instructions as posted, and except for having to add the command 'shell' to the mount statement, everything worked fine. And, it accomplishes exactly what I was after.
Next I may look into trying your library and reader apps.
Thanks again!
MildBill
P.S. You might consider rewriting the readme file included in nook121patch.zip to better describe what each patch does.
The readme is admittedly very old.
That's because I forgot that it's even there!
Each of the individual smali files has comments at the head saying what it does.
I'll make something to compile the individual comments into a single readme.
I can also report, at this point, that unlike an other method I have tried to accomplish this simple task, this one does NOT run thru battery life like it was going out of style.
The next most popular option, NookManager, which uses the NookModManager to do this fix, uses an average of 10% battery life every day, even when in in sleep mode the whole time. Turning the option off (I.E. reinstating the swipe to unlock) again reduces battery drain to a more normal point.
But, the fix by Renate seems to use nomorebattery than the stock reader, whether reading, sleeping, with WiFi on or off. I like it!
Once again, Renate, thank you very much for this, and for all you have done for the Nook community.
