[Q] Porting an CLI app to Android.

Hi XDA Dev's,
I have a program called words. It's a windows based, but ported to linux program which is able to function as an English to Latin and reversed dictionary.
The program has to be ran in the Terminal, cos it is command line interface based.
I thought since it is a program ran in the Terminal you should be able to run it in the Android Terminal, but that's just a theory.
Practically it doesn't work that way.
After untarring the app I entered ./words or su ./words but either won't work.
It gives me the following:
(I took the block from the internet so hope you see a block, not some kind of symbol: )
EL4: not found
4: not found
4: not found
: not found
./words: 5 Syntax error: "(" unexpected
So I think the Android Terminal reads differently cos it doesn't expect that character.
The question is: How can I port a linux CLI program to Android? And is this possible with the App Inventor from Google?

I don't really understand ypur question. If you would like to run a shell script try this
Code:
sh script.sh
Sent from my GT-I5700 using XDA App

Hmm sh gives me almost the same error.
But that's the thing, I have no clue what it is, there are a few files which are being used by the program. One of them is words, but it has no extension.

Hi, If you can get the source code to the program, then potentially the program can be ported to Android/ARM CPU architecture. The fact that it is a command-line program isnt such an issue - an Android app can be designed to interact with that (eg using Runtime.getRuntime().exec()).
If you just copied over the binary that runs ok under Linux on your PC, and tried to execute it on your Android device, it wont work. Your PC is running x86/x64 based CPU, your Android device is running ARM based CPU (eg you're putting diesel fuel into a car that needs petrol).

If I had the dictionary file, I could put it on my hosted site and write an app.

You said it like it's that easy; but if you want I'd appreciate it.

I already made a concept of what it could look like with the App Inventor, but I don't mind else:

I hope you're able to do it. I'm really bad with linux.
Good luck

http://users.erols.com/whitaker/words.htm is the page for this program. It's written in ada and the author supplies the source. It will probably not be much harder than just compiling it for android once there is a working cross compiler, GNAT AUX is working on one currently http://www.dragonlace.net/posts/GNAT_AUX_ported_to_Android/.

[Q] [Solved] How to determine PATH for busybox binary location?

I'm hoping to be able to get some feedback and bounce this idea around. I wasn't able to figure out the right terms for a google search with good results even though I spent a while trying.
From an Android application, I want to determine where the busybox binary is installed on the system or data partition. I was hoping for a pure java solution, but I don't think there are any android java APIs for calling the shell PATH variable...
I also wanted to avoid hard coding the common linux binary directories (ex. /system/bin and /system/xbin, etc.)
From a shell perspective, I would usually run busybox find / -name busybox to locate it. Or I'd run busybox which busybox .. none of these are pure Android java solutions.
There are only two ways I'm aware of:
1) Using the linux binary "which". I could compile this for arm (or use the busybox applet) and package this binary into the application, have it extract when the application loads and execute and parse the output. Could do the same with the find linux binary...
2) Use the RootTools method Stericson published - InternalMethods.java. Although his approach uses a root shell to run dd to copy it from /init.rc (permissions usually read only for root) into /data/local/tmp and set it 777 so the android application and parse it for the export PATH line.
EDIT: found another method .. kind of an interesting approach.
http://osdir.com/ml/AndroidDevelopers/2009-03/msg04053.html
ps | grep /system/bin/sh
cat /proc/<pid>/environ
have to parse some of that output, but it seems to work thru adb shell w/o root.
I very well might have overlooked something or missed another approach. Any other ideas or other approaches?
Thanks in advance!

Include busybox with your app, no need to worry about its version

Couldn't you use java.lang.System.getenv()?

lol. unfortunately the scope of my app is only to show the user where their busybox binary is currently located, not provide them with a busybox binary.

Wow! very interesting. Sad I couldn't find this in all my searching through the android docs.
Two questions after looking over the information I can probably answer through testing, but can't test at the moment. If anybody knows the answer, would be helpful. Otherwise I'll post back when I am able to test.
1) Would the SecurityManager block a 3rd party app from using this call as it might be reserved for only apps signed with platform keys? I can compile and test watching logcat to see if it blocks this call.
2) For the getenv(String name) method, what value should be passed as the string? I can probably bypass this by just running the getenv w/o a string to have it return the Map and sort through the map.
Thanks for the help/suggestions/feedback!

Finally had a chance to test!

[APP] findutils 4.2.33 (updatedb / locate) for Android

Introduction
As I like to stay connected via Putty to my Android phone, from time to time I missed the functionality of updatedb / locate that I so got used to within Linux environment.
I've decided to cross compile the findutils package (I couldn't get the latest version 4.4.2, but an older before, 4.2.33).
Screenshot
You can see the updatedb command followed by some locate commands.
{
"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"
}
Installation
Busybox is required.
1. Copy the archive onto your /sdcard/ folder.
2. mount your /system folder as read-write
3. cd /system/
4. tar xf /sdcard/findutils-4.2.33.tar.gz
It is mandatory that you are inside /system/ folder when you extract the archive.
Then you have to create the database (using updatedb script). It will take a bit of time - but not too much.
Then you can use the locate command giving any part of a file name that you can remember, you can also use wildcards!
Observations
1. No integration with cron / etc. If you know your updatedb database is out of date, rebuild it using "updatedb"
2. Busybox comes with a /system/xbin/find command. The trouble with it is that it doesn't support the fstype argument, and thus, updatedb cannot prune some standard file system type paths. However, the bundled package here comes with its own find utility which unpacks into /system/bin/find.
3. Busybox is required for sort / sed, but updatedb script is patched to use the /system/bin/find (its own find executable) instead of the default busybox one.
4. My phone did not have an /etc/mtab file (list of mounts which mount is supposed to update whenever something happens). Thus, there is a line in the updatedb script which recreates that file on each updatedb invocation (mount > /etc/mtab). If you phone / tablet has it, please modify updatedb script and remove the mount command.
Download
Use it at your own risk!
findutils-4.2.33.tar.gz

This is great! Thanks for your work!
I hope that there will be a file manager for android which uses updatedb/locate to index/search files in the future, that would be sooooo awesome!

Don't know about other software that searches - but it would be nice too.
Maybe I can create something, but I'm sure there are others more integrated - such as looking in SMSes or in mails too, etc.

nice! find takes for ever lol now i have locate!

Any chance of getting the code. Did you create your own Android.mk? Did you use the FindUtils make?

When I run updatedb, I get these errors:
/system/bin/find: /preload: Value too large for defined data type
/system/bin/find: /storage/sdcard0: Value too large for defined data type
/system/bin/find: /system: Value too large for defined data type
/system/bin/find: /data: Value too large for defined data type

[UTILITY][Linux] APK Suite 0.2.1 Stable

Apk Suite Linux
This is a GUI interface designed to make (de) re-compiling android applications
exceptionally easy. This is the first Alpha so we need feedback on bugs and possible future features.
The reason the file size is so small is because it does not yet actually have the libraries downloaded, to do this simply:
Control Cenrtre => Download Required Files.
It needs to be ran as root for one time only to install aapt into the /bin/ dir. After that, root is no longer required.
You can also manually place aapt in /bin/ dir and chmod to 775 if you do not want to run the application as root.
You can find aapt HERE.
The requirements are:
Python (Version 2 or greater)
IF NEEDED: PyQt
JavaSE or OpenJDK any version.
Place APKs in 'apk' dir, run the program, it will detect them. Once decoded, refresh lists to recompile (editing the smali files, navigate to 'decoded' dir)
Once encoded from a decoded package, the file is then placed in 'encoded' dir.
Please do report any bugs.

Very good work sir!:good::good: Can I request a feature? It would be even better if we could decompile it to java code over dex2jar and jd-gui.

thanks, i have an issue:

SyntaxError: Non-ASCII character '\xf3' in file APKS on line 1, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

After a little google I found it's the character 'ó', are you running APKS with a directory (includes parent) with 'ó' in the path?
The APKS code contains no such character as 'ó' or any other with accents.

No, but to be sure i moved to /home/APKS/
still have the same error.
My linux is in french but i dont use this kind of character
i tried in root and non root user and tried to fix permission just to be sure.
Still same issue

The application does check on start-up for permissions, and file installs, that shouldn't be a problem. Allow me to go overt the code and see if this is my mistake in the mean time, could you do the following?
Open terminal, CD to the directory and run:
python APKS
Edit:
Looks over the code and there's is no 'ó'
the first line is "#! /usr/bin/python"
I will remove this as it was only to make it with with source
Thanks,
T

still same error with 'python APKS'

No problem at all
I have uploaded an updated version without specifing the "#! /usr/bin/python" this might fix your problem, as this is the only thing on line 1.
Also, ensure you have "python-qt4" - sudo apt-get -f install python-qt4
Same version, just uploaded without the tag,

Thanks for your work i'll try this more.

Many of you may be familiar with ADB GUI (Or ADB Helper UI). So am I. I always thought it could use something... I don't know... Then, a few days ago, while reading the portal, I read it got an update. So I had a look and downloaded the program. I looked at it, and thought: "Well. It works! But what can I do about it, and how could I make it better? It's missing some tools..."
So then I opened up Visual Studio and coded on. I spent an entire day working out the design and how it should work and what features it should have. I had no internet at the time (Change of ISP) so I then coded and coded and coded until it was bed-time. The next day I started coding and wasn't sure about the design, so I deleted the code, got rid of the project and started anew. And the results aren't too bad!
So today I am proud to present to you, Better ADB GUI!
It's still very early and almost nothing works, but I want to show it off and release the current source code.

Well, as sad as it is, I don't code in VB anymore, and I especially don't use Windoze anymore.
So, any functionality that is found here, will:
a) Be also incorporated into my much older project Universal Android Toolkit - which will be coming very soon
or
b) Will be ported to Java for use with Windoze (Universal Android Toolkit is mutating to a BSD/BSD-like OS-only program, because we've go way to little of these.
But, you can pull the source and try it out for yourself. I can't remember what's working and what isn't, but hey. There should be a working build in thre somewhere, and you should be able to carry on maintaining it.
