What did you use to compile it on Windows?

I didn't compile it, just downloaded unyaffs binaries and grabbed Cygwin dll from cygwin binaries.
Very simple stuff but I'm not sure everyone will think to do it. Installing Cygwin is a pain, this way is much more simpler.

Cant get this to work get a STATUS_ACCESS_VIOLATION at eip=004010B0 error,have tried various tutorials/sources and just cannot get it to work
EDIT I am too stupid to get this to work,managed to get what I needed extracted by using ext2explore.

a) Well if you didn't compile it, where did you get the binaries from? (And who compiled them, what version etc.??) Give us a link!
b) Cygwin is generally a piece of cake to install! But it doesn't contain any YAFFS binaries or sources!
So what have you been doing dude, and why should we trust your stuff??
To everyone: I would NOT run any exe from this guy, unless he can show his sources and what he did.

Are you one of those purists who only run selfcompiled code ?
Unyaffs tool needs Cygwin dll to run on Windows.
"What version" --> There is only one release from Dec 2008 if you took some time for looking at project page.
Now next time be less aggresive and stop calling me "this guy", thanks in advance.

if you dont trust him why u even post on this thread about his work?

I think he wanted to get thanked. Ridiculous.

Give me a verification post and this will be my img recompile tool.!
I don't believe in bashing anyone, I think he is trying to make a name for himself like everyone else, credits to you dude, but I'm gonna hold back trying this out until I get just a little more info on it. Great work ahead of time though dude.!

I do not provide support, sorry.

Slight bump.

Is not necessary to install Cygwin. It's enough Cygwin.dll.
There are some new structure for YAFFS file iamge (ex. 8192 bytes /segment and 448 bytes /spare)
The new utility (unyaffs) can support it, but if you want to recompile it should be encessary also makeyaffs (and it should be run under Linux - not under Windows)
Some link about other utils
Unyaffs /ehlers) - source: https://github.com/ehlers/unyaffs
To compile under Windows it's quite simple.
Install Cygwinwin (downlaod http://cygwin.com/setup.exe and run it).
As modules select: "gcc", "gdb" and "make".
Create a folder under "/Cygwin/home/@username" and put here the program source.
Run Cygwin. Go to the source directory. Run "make". You will have the .exe file compiled.
Copy the compiled .exe file plus CYGWIN.DLL (available in \CYGWIN) and in other folder and you can run utility.

Yea...you got that because system.img is an ext type file, not a yaffs. Search for an ext explorer.

This utility acts weird when I have ran it first time.
- It has hidden all processes in my task manager and procexplorer (systernals),
- ProcMon (systernals) was showing that process is hooked to system32/wow64 and registry
- it raised 6 (out of 44) cores of my CPU to 100%
- I couldn't exit nor kill command windows. As I run windows server 2016 which is very reliable I find strange that one can't kill a command window.
After reboot:
- I moved this into vmware to analyze with olidbg but then it behaved as it should.
- olydbg shows that exe imports kernel dlls which is unusuall since cygwin provides integration with the OS.
My feeling:
- I would not use this exe again.
- When I see communication between member who provided it and others, I trust it less.

[TOOL][WINDOWS] Android Multitool

Android Multitool
Hello,
I´m glad to present my Android Multitool wich makes it easier to decompile/recompile applications + jar framework files. You can also sign your apk by easily clicking a button.
Requirements:
Winows OS XP / 7 / 8 / 8.1 / 10
Installed Java on Windows
Installed Microsoft Powerpacks
Installed .NET framework
- Easy handling: Select your apk and push the "decompile" button!
- This tool makes modding much faster and easier, no cmd handling any more.
- You can read the log which is integrated in the tool to find your mistake in the error.
- ADB inside: Push files into your file system with a few clicks
It looks like this so far:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
How to use this tool?
Follow this small how to!
Here you go..
Well, first extract the AndroidMultitool folder to C:\. Otherwise it probably won´t work
-copy your framework-res.apk in the Framework-Files folder and other files you want to mod in the "Files" folder (this folder is for all your files you want to mod, don't pick files from any other location)
-Next you have to start AndroidMultitool.exe
-select your framework-res.apk and push the "install" button (check log for errors)
Decompiling and recompiling apk files:
-select the apk you want to mod/decompile and push the "decompile" button (check log for errors)
Note: You can check the "use baksmali" checkbox, then e.g. the useless .line text will be removed
-your decompiled apk will be located in C:\AndroidMultitool\Decompiled_apk"apkname" as a folder
-if you want to compile your apk again, select your decompiled folder, check the "apk" radio button and compile it again (check log for errors)
-your recompiled apk will be located in C:\AndroidMultitool\Compiled_apk"apkname"
Decompiling and recompiling jar files:
-select in the combobox ".jar" (check the "use baksmali" checkbox for deleting the useless .line comments)
-select the ".jar" file you want to mod
-push the "decompile" button
-your decompiled jar file will be locaten in C:\AndroidMultitool\Decompiled_jar"jarname"
-for recompiling you have to check the "jar" radiobutton and select the folder within your decompiled ".jar" file
-push the compile button
-your compiled jar file will be located in C:\AndroidMultitool\Compiled_jar"jarname"\classes.dex
-delete the "classes.dex" file in your ".jar" file
-copy the new "classes.dex" file you compiled in the ".jar" file
Signing apk files:
-select the ".apk" you want to sign
-push the "sign" button
-the signed apk file is located in C:\AndroidMultitool\Signed_apk"apkname_signed"
Using tags:
You want to decompile many files from different devices or different android versions / frameworks? Tagging makes it possible!
- before installing your framework type in any tag (like "hero")
- then install your framework and work normally
Android Debug Bridge
You want to push files with adb to your device? Follow these instructions:
Please klick on the "advanced" register in the tool
-push "check" to control if your device is ready
-if the device is not ready please follow the instructions, which are listed in the tool (device offline, no device...)
-if the device is ready, choose a file you want to push
-choose a path on the device, where the file should be placed later
-push the "push" Button
-alternately: press "Reboot device" to reboot your device and to let changes take effect
If there are any questions or bugs, please post them in the thread.

Enjoy easier apk handling!
Having issues with the program?
Try the batch version developed by @bovirus (it's also in the AndroidMultitool folder)
Questions and answers:
Q: The programm does not start, it crashes.
A: Please install Powerpacks, this one: http://go.microsoft.com/fwlink/?LinkID=145727&clcid=0x804
Q: What do you mean exactly with "!!!NOTE!!! After compiling you have to copy the AndroidManifest.xml and the META-INF folder from your old apk to your newly compiled one!! Otherwise you´ll get bootloop! " .. I don't understand.
A: You have to open your old apk (this one you selected for decompiling in the folder /files) and copy from that apk the AndroidManifest.xml and the META-INF folder to the apk you just decompiled and recompiled.
Q: I followed all steps in the startpost but I'm still getting this error: "apktool is not recognized as internal or external command"
What can I do?
A: Please refer to this post by @LasVegasRomeo: http://forum.xda-developers.com/showpost.php?p=51017662&postcount=681

v2.2 Beta1:
apktool 2.0.0
Details:
Details
v1.5.x -> v2.0.0
Java JRE 1.7 is required!
Update apktool to v2.0.0
aapt is now included inside the apktool binary. Its not required to maintain your own aapt install under $PATH. (However, features like -a / --aapt are still used and can override the internal aapt).
Remove framework $HOME/apktool/framework/1.apk or manually update via (FrameworkFiles)
Eagle eye users will notice resources are now decoded before sources now. This is because we need to know the API version via the manifest for decoding the sources.
Parameter Changes
Smali/baksmali 2.0 are included. This is a big change from 1.4.2. Please read the smali updates here for more information.
-o / --output is now used for the output of apk/directory.
-t / --tag is required for tagging framework files
-advance / --advanced will launch advance parameters and information on the usage output.
-m / --match-original is a new feature for apk analysis. This retains the apk is nearly original format, but will make rebuild more than likely not work due to ignoring the changes that newer aapt requires.
After [d]ecode, there will be new folders (original / unknown) in the decoded apk folder.
original/ = META-INF folder / AndroidManifest.xml, which are needed to retain the signature of APKs to prevent resigning. Used with -c / --copy-original on uild.
unknown/ = Files / folders that are not part of the standard AOSP build procedure. These files will be injected back into the rebuilt APK.
apktool.yml collects more information than before
SdkInfo = Used to re-populate the sdk information in AndroidManifest.xml since aapt requires it to be passed at runtime.
packageInfo = Used to help support Android 4.2 due to renamed manifest packages. Automatically detects difference between manifest and resources and performs automatic --rename-manifest-package on uild.
versionInfo = Used to re-populate the version information in the AndroidManifest.xml since aapt requires it to be passed at runtime.
compressionType = Used to determine the compression that resources.arsc had on the original apk to duplicate on uild.
unknownFiles = Used to record the name/location/compression type of non-standard files in Apk.
v2.1:
fixed freezes
bigger UI for better overview
option to save log to a text file
other small fixes
v2.0:
complete code rework
folder structure for a better overview
decompiled, recompiled, signed files will be located in their own folder
no more messy file handling
added radio buttons for choosing jar or apk
some graphical changes
added info button in the "installing framework" section
V1.2:
Added ability to decompile and recompile ".jar" files
Added baksmali
FolderBrowserDialog: If you push the "browse" button you are in the right directory now and needn't to scroll and search the "AndroidApktool" folder
other small fixes
V1.1:
Added ability to sign .apk
Changed comboboxes to browse buttons
bigger log - screen

put the file in it in Framework-Files sub-folder of Android Multitool and install it in Android Multitool.
Then try again to decompile/recompile the application.

Very nice tool!
One feature request, could you have a checkbox for say the -b command so that we can get rid of the useless .linexx and .prologue lines? That would make this tool perfect
Another feature is adding the twframework-res.apk as a framework file? Thats essential for modding samsung system apk's. I usually have to install both twframework-res.apk and framework-res.apk before decompiling. Maybe adding 2 slots for the framework in the tool?
Thanks again!!

Good work bro....

Sure, adding a second slot will be no problem!
But I don't know what you mean with this checkbox, could you explain me exactly what you mean?

When I decompile using baksmali this is the command I run...
Code:
java -jar baksmali.jar -b -o c:/smali c:/smali/classes.dex
The -b command prompts baksmali to remove all .line type code from the smali.
Here is an example .smali file before and after the -b command...
BEFORE: http://pastebin.com/gYKQ90cW
AFTER: http://pastebin.com/17i8k1X2
This method of decompiling smali makes it much much simpler to compare to other code.
Thanks!! :highfive:

Ah, I'm understanding. Yes, I think that's possible as well!

Cool. Cant wait
One more thing, will you be adding the ability to decompile more then one apk/jar?

At once? Would work, I think.
Two possibilities:
The first apk decompiles, and then the second one
Or: Both are decompiling at the same time, but in two different processes.

One then the second and so on would save the most memory and prevent crashes on weaker machines

Hello, there can be a lot of things.
Maybe you are missing the .NET framework, or some dll´s.
I also uploaded a new .exe just for testing. New is the progressbar.

best regards "D"

Could anybody test trying to install .NET Framework?
Hopefully I get a solution for this problem, otherwise I'll make an Installer.
~ via Nexus

@Flextrick
I have NET Framework 4.5, Java 7 Update 25 and Java SE Development Kit 7 Update 25.
Edit:
You've got a Private Message
"D"

Ok. For starting the Tool is no Java necessary.
I think the dll's are missing, hopefully I get it working as far as possible.

This software will ask for sudo permissions in your machine to download and install all required tools for this program to run correctly, also, it'll execute chmod and chown to this program files and ~/.megarc (if exists) for the correct functioning of all the code, I'm not responsable if this program breaks your Machine (which it shouldn't be able by no ways). When you run for the first time this program, it will proceed to his first run configuration after the user authorization.
Welcome, I've been developing this program a long time ago with my free time after college, this is my first project made in Bash, the main purpose of all this software is to make a lot easier the process of building a Kernel, no matter which device you're building to (excluding MTK and those without source). This program will automatically download all required tools for Kernel building (~1.5GB), including the CrossCompiler (GCC arm/arm64) and other misc tools. You don't need a lot of knowledge to build your kernel with this software and it has all the tools for automatically build everything in just one command!
Requeriments:
A machine with Linux
Git
This program
Once you've downloaded the program to your Machine, you have to cd with Terminal to where you downloaded all the files and execute "core.sh" (bash core.sh or . core.sh) (Like this Example), this is indispensable every time you want to run the program, because it sets the program paths (Otherwise it'll not work)
Now, How it works?
Once you run the program, if it's for the first time then it'll automatically download all required tools and install them, after this it's time to setup your environment. You'll see a folder named "source", you have to put there the folder with the Kernel source contents like this and another folder named "templates" where you can set your AnyKernel (only AnyKernel for now) templates for different devices (Or just use the local one).
That's all, this program only needs you to set the Kernel source, now you've to run again core.sh and it'll prompt to you all the data needed for that session, like the name of the kernel, target android, version, kernel source folder, etc... When you've to select the architecture of your device, arm or arm64 and it'll download the correspondent CrossCompiler (GCC 4.9), after this, it'll promt to you how to set Kernel Installer template, the first option is to extract the local AnyKernel source into "./out/ak_template/" (Thanks to @osm0sis), second option is for select a user template from "./templates/" folder and the third option requires you to set manually the installer template inside "./out/ak_template/" similar or like this (Remember to configure it).
When it promt to you the variant, you've to put preferably the codename of your device (For example: Oneplus One codename is "bacon") and then select a defconfig for that device (For example: For Oneplus One it would be "lineageos_bacon_defconfig"), now that the program knows for which device It's going to compile, (You can add more variants) then, you can enable the KernelDebug option to enable the creation of the Device tree image (Applies for arm devices only) and allow the kernel source cleaning on every compiling process...
Now, let's get into the commands:
Command: "essentials <flag>": Here is where you start once you finish setting all the configs, 'essentials' is the main command of this program, but it only works with flags, otherwise it'll display the flags information that I'm gonna show right now:
Flags:
--kernel (Start the process of compiling your kernel)
--dtb (Generates the device tree image, applies to arm devices only)
--anykernel (Builds a installer for your kernel based on Anykernel by @osm0sis)
--upload (Uploads your Kernel installer to the root of your MEGA storage)
--all (This flag does all processes mentioned above)
You can combine all the flags except for "--all", because this one already does everything, also, no matter in which order, all the functions are going to be done in order to prevent an error (For example: 'essentials --anykernel --kernel' will build the kernel and then build the installer).
Also, after the first run, theres a file named: "defaultsettings.sh", it has a variable inside named "DSENABLED", if you set it to 1, the program instead of prompt you for information when you run "core.sh", it'll take all the config directly from that file, just make sure you've configured it first. :good:
Command: "auto <device> <flag>": This command allows you to make pre-configured files for a specified device, it requires that you have executed the program core.sh for the first time because it stores some config in your ~/.bashrc file, then, you can turn on or restart your machine and this command will still be available for it's use.
When you run 'auto' and next to it you specify the device (for example: auto oneplus), if the device (oneplus) doesn't exist in the device database (./resources/devices/) then, it'll promt to you all the data required for kernel, dtb (if applies), anykernel and upload process.
Once you have configured your device it'll be stored and when you run again the command 'auto' followed by the device name you configured before, (for example: auto oneplus) it'll load that device config file and build everything automatically (Kernel, dtb if applies, anykernel and upload if its enabled).
The Flags for this commands are:
--edit (Opens you the <device> config file for editing with nano)
--remove (Simply removes the <device> config file)
For more information I highly recommend to read the README.md in this program source on Github (It contains a more datailed and complete information).
This program has been tested and used on the following Linux distributions:
Ubuntu
Debian
I will really appreciate any feedback about how it performs on other Linux distributions
You can contact me with a PM (private message) here or in my Telegram group! (I'm @ArtxDev)
Me, @Stayn (Artx)
@osm0sis for his AnyKernel
This project on Github is open to pull requests, I will not hesitate to dedicate you a space here if you contribute for this project :good:
I'll be updating this program fixing bugs and bringing new features :good:
If you like it and want to do a small donation it for sure is gonna help me a lot and keep me motivated! :laugh:
Thank you and enjoy it!

Cool project! You should specify bash in the shebang (normally the first line of a shell script) to fix issues where bash isn't default:
Code:

Hey guys, now Kernel Building - Essentials it's stable!
I've been working on fixing a lot of bugs and updating the program structure, now that the structure is totally defined and I don't need to change it anymore, I'll upload the first release at GitHub, version 1.0 and the next versions will be coming with a file to update your old version on KB-E (In this way there's no need to clone the repo again and again and merging your devices or configuration...)
There is all the updates and changes:
- Added a folder for Multiple Installers Templates: I've been thinking that anyone could have various kernel projects for different devices, so this means, that the templates for the installers needs to be different, so, now you can trow all the templates you want inside "templates" folder and the program will prompt to you which one you'll use for the current session (using core.sh "essentials" command) or a pre-configured device (using auto.sh "auto" command)
- Replaced option 2 in the program installer template config method, removed the ability to download the template from your MEGA Cloud and replaced by a selection of user templates inside "./templates/" folder
- Changed the "setuptools.sh" file name to "programtools.sh" because, all program misc functions are going to be stored there and "programtools" makes more sense
- Fixed a bug that happened when you didn't gave to the program the device variant (or codename) and then, "essentials" and "auto" command were not working, now the program forces you to set it (You can set your device name as device variant but it's preferably the device codename)
- Now when the program downloads the correspondent crosscompiler, it shows you the process
- Added the package "device-tree-compiler" into the download list of the function "installtools" (Executed when you run the program for the first time), this package is necessary for some arm64 sources to build device tree
- Fixed a annoying bug that cd's you to your "~/" directory instead of the current directory you were after executing "essentials" or "auto" command
- Now core.sh doesn't change the whole file permissions of your sources (sorry for this)
- Added a boost functionality for "auto" command that sums 2 threads to the compiling jobs when compiling the kernel (Recommended for machines with more than 2 real cores)
- Updated README.md
I would really apreciate some feedback guys, if you have any problems or you need help, feel free to contact me via my Telegram Group, enjoy!

Hi, it looks good so far...I have an MT6580 that I play around with but it's been stuck on kernel 3.10 for a long time. I've spent weeks trying port kernel from other MT6580 devices but haven't gotten any success yet. I got through the core.sh part. Is the essentials commands next ? I don't see it anywhere in the program.

Now I know how you automatically upload kernel to Mega Drive using code.. Unfortunately my G3 was Died...:crying:

Anyone know how to remove unwanted feature from a cooked/compiled kernel?

Excuse me, does this work on Ubuntu that runs on Windows Subsystem for linux?
By the way, thank you for the amazing artx-powered TWRP on my G3.

KernelSU - Kernel-Assisted Superuser for Android Root Shell

Like being able to do quick cycles of `fastboot boot out/arch/arm64/boot/Image.lz4-dtb`, but annoyed by the lack of root this way? Well this atrocious idea might be the thing for you!
Git repo: https://git.zx2c4.com/kernel-assisted-superuser/about/
Instructions:
1. cd into your kernel tree.
2. Run this command:
curl -LsS "https://git.zx2c4.com/kernel-assisted-superuser/plain/fetch-and-patch.sh" | bash -
3. Enable CONFIG_ASSISTED_SUPERUSER=y in your config.
4. Gain root by running su.
For so many reasons, this is an awful idea and totally insecure. Don't ship kernels to your users with this enabled! I've tested this on the Pixel 3.

Good stuff! Keep it up

Great, actually amazing, work on this,. I'm sure Google will be having a meeting of angry "security specialists" sometime soon crying about the future of Android.
Also can't wait for the first idiot to put this in their production kernel.

A really amazing idea that needs to improve it's implementation. Kinda curious to see how this will connect with an userland "Manager" app to allow or deny root permissions to specific apps.
Best of luck

I'm having the same problem, not really tripping on it tho since it's still a new thing.
Question though, would this theoretically become a solution/work-around having a locked bootloader? Or does the OEM toggle still need to be a thing?

Brilliant. Compiled and used successfully!

Awesome stuff. Can't wait to see more development on it! Keep it up

Thank you for your time.

Great concept. Thanks for developing it.
It's working like a charm here on an engineering build of APGK, although a lot of apps (e.g. AdGuard and Titanium Backup) don't recognise the availability of root via this mechanism.

This is a really interesting way of getting root access. this combined with an application to direct it would be amazing!, great work !
Cant wait to implement it in my test kernels. reflashing root every build is annoying :laugh:

For arm64 only?? I tried it in 3.4 kernel, arm device and it gives error when compiling with this patch..

Yes. It works now. It works when I use "git clone --depth=1 -b".
It patched successfully and I also compiled without any issue. I will test the kernel later tonight and see if it works for arm. It is very useful for Android Wear/wear os. No need to use supersu and magisk. I will let u know later. Thanks again for your effort to bring this. keep it up.

It is kinda strange. It applied and let me compiled successfully with source "android-wear-8.0.0_r0.51" but failed to compile with "android-wear-p-preview_r0.5". It gives me the above error.

Good job!
Kind of works as intended for me... Though, when I run 'su' in terminal I get:
"You are now root.
Killed".
However. I do have 'su' access in terminal without running it, so I guess it's kind of working as it should?
Only Root explorer has managed, so far, to work using your kernel su.
Titanium Backup complains about su not being found (It does look in /system/bin/su, so it should work I guess).
Edit: This is on a Mate 10 Pro using Pie.

Simple shell / terminal app "Hello Word" template / example? [written in Java, not C/C++]

I cant seem to find an example of a simple "Hello World" terminal / shell application, in Java. All the simple examples on the web I find are for a simple "Hello World" GUI app. I wish to write some small utility apps to extend the shell with stuff I can easily do in Java, but not directly in the shell with ASH (ie android BASH).
Because it should be very tiny, I would like to write multiple tiny single use ones using a text editor, once I have a template up.

I guess that is a programming tool question? C++ or C? No clue what you're asking, but I am sure you're not asking about a simple Terminal emulator because it's you

Its written in Java. It could of been written in C++, but thats not what I want. And its not writing the terminal itself, but a java app with no GUI, but access to the android API.
Most examples I have seen are just too complex. For example. sqlite2 shell binary is one, but it does so much. If you look in /system/bin there are many of them, but I would guess a lot are written in C++. I have thought about checking the ROM source to see how these are coded, but I really suspect many are C++ and with the size of code for a ROM, it would take time, and many are more complex than an "hello world".

I had an idea for some more search terms, and came across the following; and similar. But none show how to compile it down to a standalone executable. All the examples I found require you to run it interpreted.
Hello World
introcs.cs.princeton.edu
Maybe now is a trim e too try and integrate what I see in SQLite3 make file and the above link
EDITY: Arggghhh SQLite3 source would be C/C++ not java

I don't know if you can compile standalone executable. have a look into cat /system/bin/sm

Android: Compiling and running a Java command-line utility

Im getting close, but have to move onto other things.
Had to download SDK etc and modified the build scripts to newer methods/modules. I have the dex, next to compile that to static executable
just looks like downloading a dependency. Or maybe a path as that error looks familiar
Code:
[email protected]:~/android/helloworld$ dalvik.sh HelloWorld.java
** Compiling java file...
** Creating temporary jar...
added manifest
adding: HelloWorld.java(in = 170) (out= 141)(deflated 17%)
adding: diamondjohn/(in = 0) (out= 0)(stored 0%)
adding: diamondjohn/android/(in = 0) (out= 0)(stored 0%)
adding: diamondjohn/android/utility/(in = 0) (out= 0)(stored 0%)
adding: diamondjohn/android/utility/HelloWorld.class(in = 590) (out= 356)(deflated 39%)
** Creating DEX file...
** Creating Android compatible file...
<-=ERROR=->
aapt: error while loading shared libraries: /lib/x86_64-linux-gnu/libc++.so: file too short

one step closer!
I can now
write a simple java class with a single method using a text editor
Code:
package diamondjohn.android.utility;
public class HelloWorld {
public static void main(String[] args)
{
System.out.println("Hello World!");
}
}
compile it to a dex on Ubuntu (a couple of steps I need to clean up)
zip the dex (actually did this step on windows using the GUI )
Copied the files to and run the class using the following in an android shell over ADB WiFi.
dalvikvm -cp /data/local/tmp/HelloWorld.zip diamondjohn.android.utility.HelloWorld
and the output is as expected
Hello World!
two things before I am actually there
1. Its still not a standalone executable, but, if need be, I can write a shell script wrapper to handle the execution using the dalvikvm. What it does show is that I can write shell executable code using Java (Instead of C/C++). And, it looks like it *should* only be a small step to make it executable in itself. At absolute worst, I could write a simple C++ executable to wrap my java executable that calls dalvikvm, if I didnt want to use the shell at all.
2. The next thing to try is to actually use an include of an android specific API and get that to compile on ubuntu and run.
for example
Code:
import android.util.Log;
public static void logInfo(String logText) {
Log.i(TAG, logText );
return;
}

In ye olde days all the Android commands like am, pm, etc used a shell script that called /system/bin/app_process.
Now those use the /system/bin/cmd executable.
Usually I go the other direction. I avoid running things in Java.
You can just have a regular ELF executable.
If you need to interact with Android (Java) you can directly use Binder. (I have.)

DiamondJohn said:

No, but it's basically all the same. You need an ELF (like dalvikvm or app_process) to load a jar/apk and a method for it to start with.
I didn't know about dalvikvm.
The way that app_process works is that the ELF uses libbinder.so to ask zygote[32][64] to fork itself, load some classes and start somewhere.
Try this:
Code:
time dalvikvm -cp /data/local/tmp/HelloWorld.zip diamondjohn.android.utility.HelloWorld
You'll see that this is comparatively slow (certainly over a plain C program).

No GUI/Activity, so no APK.. As for ELF, from what I read now, it appears to be similar to OAT files, pre-compiled for native execution?
I havent looked into it, but maybe an extra step to call dex2oat and then run that (ie the OAT), may work. I will look into it later, as Its a pretty easy process to get to the DEX. Now that I know an example of the method.
The thing to remember, I want to be able to call these methods from the shell, not from another Java app.

Yeah, you an me both!

Try this:
Code:
time dalvikvm -cp /data/local/tmp/HelloWorld.zip diamondjohn.android.utility.HelloWorld
You'll see that this is comparatively slow (certainly over a plain C program).

Speed is not of concern at this stage. Functionality is first. I do not expect to be calling these in hard loops. And if I did, I would put the hard loop in the compiled Java code.

dx is still around and it might be less trouble.
d8 has wacky new Java features.

My original findings were using dx but when I downloaded the latest A13 SDK, there was no dx but there was a d8 so i guessed and it worked. I am not expecting to write huge programs, most of the functionality will be in the shell, with calls out to these tiny utilities for what cant be done in the shell i.e in exceptional cases. For example, in prior android versions, one could media scan a specific single file. Now, you can make the same call in the shell, no error is returned, but no file is scanned. i.e. it is ignored and you are not informed that it was ignored. I havent checked the logcat.

Do you mean include or import? Which ones?

My bad, I mean import
Code:
import org.apache.commons.cli.DefaultParser;
import org.apache.commons.cli.HelpFormatter;
import org.apache.commons.cli.Option;
import org.apache.commons.cli.Options;
import org.apache.commons.cli.ParseException;
These names do not look like AOSP available imports.

They look like some Apache libraries for their idea of what you need to interact with command lines.
There's no reason that you have to use them.
If you did you'd have to get (or make) a jar (with classes, not dexes) to compile against.
You haven't given us any hint of what you are trying to do with this all.
You might be better off with a standard app with a service that can be commanded by a pipe or socket from the command line.
Code:
$ time input keyevent 4
0m00.82s real 0m00.21s user 0m00.16s system
$ time ./lgtest unix.txt 55>/dev/null
0m00.04s real 0m00.02s user 0m00.01s system
This is just a comparison between the system input and a random non-Java utility of mine.
And this is what is inside the input shell script.
Code:
#!/system/bin/sh
export CLASSPATH=/system/framework/input.jar
exec app_process /system/bin com.android.commands.input.Input "[email protected]"
So you see that it has to spin up a VM just to do trivial things.
As I said, I very much tend the other direction, avoiding Java for utilities (of course I use it for apps).
The advantage is not only faster operation but that it can work when the Android subsystem is stopped or in recovery.
In any case, our interests are diverging here.

It's possible to run it in recovery though.

I think you may of just inadvertently just resolved the majority of my need/wishes!
The whole reason I was looking into all the above was to be able to access the Android base API from the shell. The following code you just posted appears to be doing exactly that, without needing to be compiled. Ironically you chose as your example a JAVA call to a method that is available in the shell
Code:
#!/system/bin/sh
export CLASSPATH=/system/framework/input.jar
exec app_process /system/bin com.android.commands.input.Input "[email protected]"
I havent tested it yet for myself.
Sure, there will be some interfaces that will be practically unusable directly from the shell (due to data types/object refs, activity contexts etc etc etc_) but I think you just gave me an "out"
As for "what" I wanted to do with it, nothing at this exact moment, it was more of something I keep repeatedly hitting but never got around to solving. I had work arounds for some. For example, the app in my sig is basically a GUI menu system as an entry point into shell commands/scripts. However, I have a small number of items I did outside of this concept to meet my personal needs when I could not find shell solutions (apart from the App GUI of course). This original post was a few weeks back now, and the idea was from a few years back, not a specific need right now, just randomly got around to finally asking the question.
On my way out now, but I am interested to be testing this sooner than later.
THANKS!

I didn't read the whole thread, but basically the concept is the same, except the methods created there would be specific to install apps. For example, there probably isnt a method to scan a media file into the media dB. So it would have 100 different methods I dont need, yet missing the one i do need. And even if it did have the one above, next week there will be something it does not do, that I wish it to do.
