hi all
i have created a custom rom for myself because i want to add a linux program: scanmem
i have copied the file in system/xbin
using this guide http://lukasz.szmit.eu/2009/12/making-your-own-rooted-android-rom.html on step6 for su command
the problem is that doesn't work ...
when i open a terminal in my desire and type :
su
scanmem
i receve this message:
scanmem: 1: syntax error: "(" unexpected
any help, suggestion ? scanmem is compiled for i386 32bit

There's your problem.
Code:
[email protected]:/tmp$ file busybox
busybox: ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, for GNU/Linux 2.6.14, stripped
[email protected]:/tmp$
If you don't have the source, time and a cross-compiler, you have a problem It's also Little Endian from memory.
This is the busybox binary I tested in case you want to strip it down: http://benno.id.au/blog/2007/11/14/android-busybox
i found a lot of information with google
http://www.kbrandt.com/2009/06/how-to-cross-compile-the-bash-shell-for-android-15.html
i have the source maybe i can compile for arm

Precisely. You should also check the dependencies (if any) and make sure you cross-compile those too.

oh my god
depends on libc6 and readline6, i have to cross-compile half gnu/linux
out of my hand
Shame :/
Why did you need it anyway? Perhaps there is another way for what you want to achieve.

i think it was an easy program to port and with a frontend for android I would have used it as the first cheats system like cheat engine for pc
I made this. I compile scanmem fo my android phone (p500) from sourses.
He even gets up and running, but not quite.
Opt for a process (pid command)
It finds regions of memory. But during the search, crashes ". bus Error"
Maybe it's because of the specificity of an android, or due to the fact that I had to change all calls to readline lib, because otherwise the project will not compile.
I will continue to watch and understand ...
Done. Scanmem works fine on my phone.
Ok, so I've a newly installed 64bit ubuntu, and I've just downloaded the android SDK.
I managed to run the "android command the first time round whereby I successfully downloaded android versions 2.3+
I was very clever and did this through the terminal, by going in to my android SDK directory, and then tools (for me cd /android/tools)
and then I typed android, and the gui came up..... all good.
I then decided I needed to add this directory to my path, I did some jiggery pokery here, not too much, but I cant say exactly what I did, but now, when I try to run the android command, from the correct directory all I get is the following:
Code:
[email protected]:~/android/tools$ dir
adb_has_moved.txt dmtracedump hprof-conv NOTICE.txt zipalign
android draw9patch layoutopt proguard
ant emulator lib source.properties
apkbuilder etc1tool mksdcard sqlite3
ddms hierarchyviewer monkeyrunner traceview
[email protected]:~/android/tools$ android
android: command not found
I know this must be down to some kind of path error, but i'm lost as to how to correct it. I've googled all over, but every explanation seems geared towards someone with more linux knowledge than mine. Please may someone explain really simply how I fix this? thanks

Yes, this is in the wrong forum. But im a 'noob' and I cannot post/reply in the dev sections just yet. Please move this thread to the relevant section.
Or better yet, add it as a reply to this thread: http://forum.xda-developers.com/showthread.php?t=1290503&page=1
First, some history:
The SBKDetect binary can be used in a 32bit Linux environment to grab some useful information for our brainy dev's.
In this instance, the dev team are asking for people who own Asus TF101/TF101G with serials beginning with B70 or B80 to run this binary while their tablet is in APX mode and copy/paste the results in the thread.
To run the binary in a 64bit enviro all you need to do is install ia32-libs
User 'thorntree' was experiencing problems running this binary in his 64bit Ubuntu enviro and was receiving the error
Code:
./sbkcheck: error while loading shared libraries: libusb-1.0.so.0: cannot open shared object file: No such file or directory
My TF101G has a serial beginning with B90. I dont think there are any other users with a B90 that have run sbkcheck, so im very keen to run it. As im sure the devs are keen to get the results from this B90 TF101G.
---
Now the juicy bit:
(Disclaimer: I am by no meaNow the juicy bit:ns a Linux expert, so the process I went through below may be incorrect, but I seem to have made *some* headway, hopefully someone else can clean up and finish it off)
I was also experiencing this error on my 64bit Ubuntu (BackTrack5, actually) enviro.
- lsusb confirmed that my device is in APX mode.
- Using Aptitude I reinstalled libusb-1.0 and ia32-libs, this isnt the issue
- A find revealed that libusb-1.0.so.0 can be found in /lib and /usr/lib
- a 'strings sbkcheck' shows:
Code:
/lib/ld-linux.so.2
libusb-1.0.so.0
- So I assume that the binary is looking for the lib in /usr/lib32 as it doesnt specify an absolute path, sure enough, the file doesnt exist in /usr/lib32
- 'ln -s libusb-1.0.so.0 /usr/lib32/libusb-1.0.so.0' gives me error:
Code:
./sbkcheck: error while loading shared libraries: libusb-1.0.so.0: wrong ELF class: ELFCLASS64
(We are on the right track!)
- ls of /usr/lib32 shows a similar file 'libusb-0.1.so.4', so I removed the previous link and did a 'ln -s libusb-0.1.so.4 libusb-1.0.so.0'
- Now the error we get is:
Code:
./sbkcheck: symbol lookup error: ./sbkcheck: undefined symbol: libusb_init
- A strings of sbkcheck and libusb-0.1.so.4 shows that sbkcheck uses 'libusb_init' and libusb-0.1.so.4 uses 'usb_init'
- Changing either file above causes a 'Segmentation fault'
This is where I am stuck... Like I said, im not Linux expert or coder, but im guessing sbkcheck needs to be modified and recompiled so that is uses 'usb_init' instead of 'libusb_init' and it should work.
Hope the above helps...
Can one of you wonderful moderators please move this thread to where it belongs? Thanks!
I think you should get the 32 bit package, extract its contents, and manually copy the libusb.ko (the correct one), to /usr/lib32. The package you are looking for should be this one: http://packages.ubuntu.com/lucid/libusb-1.0-0, just get the i386 version and copy/link over. Should work.
The ELF class error is because you are trying to load a 64 bit library into/from a 32 bit application, which won't work. The other error is because that's not the library it's looking for, and thus it doesn't find what it needs.
Hope that helps
woo, I found this gem on a search and ended up at talk.maemo.org in the n900 section.
oracle released an armv6/armv7 headless 1.6 jre binary set! way back in april, but I hadn't seen it until today.
works in debian squeeze on my armv6 (msm7627) optimus v... it runs, but I haven't put it through its paces yet for any real testing.
I thought someone might enjoy this since for a long time it was really hard to find a jre for arm debian except for icedtea, which isn't as compatible with some things as the oracle release hopefully is.
here is the post including a download link for the jre.
another post by the same user points to an arm-friendly java7 download as well.
thank you Fabry.
official Oracle java jdk now released for ARM Linux!
download page
editbsolete.
since the sun java6 jdk is available for download to arm devices through debian apt-get, but it has a set of binaries which won't work on the armv6, someone enterprising might be able to patch the jre binaries into the jdk for a usable armv6 jdk.
/end edit
edit:
to use the 1.6 jre...
download it from Oracle
copy it to /opt in your armel debian install (or chroot)
untar it there
Code:
cd /opt
tar -xzvf ejre-1_6_0_25-fcs-b06-linux-arm-vfp-eabi-headless-14_apr_2011.tar.gz
ln -s /opt/java/ejre1.6.0_25/bin/java /usr/bin/java
thank you Dak.
after that, you should be able to use java at the command line.
further down in the first linked thread are instructions for linking the jre to fennec, probably adaptable to iceweasel.
edit:
newer JDK!
JDK 8 (with JavaFX) for ARM Early Access
for armv6 hard float applications. Installation instructions for the Raspberry Pi are linked from that page. You have to accept a license agreement.
I know this was quite a long time ago, but you state that sun-java6-jdk is in debian repositories for arm, but I am not finding it.
Is there a download link for sun-java6-jdk on arm?
Hope you see this.
Take care man. And thanks for the great info!

It showed up back then when google searching for the package, but apt-get won't bring it in because of the jre dependency it can't fulfill.
they must've realized and removed it.
It may be possible to get the x86 .deb and repack it with the jre binaries or something... I actually had it installed on some chroot on my android phone to try building the android emulator on-device (which eventually worked, but the dang thing wouldn't boot in qemu.)
I'll dig around and see if I've still got it, but no guarantees.

I reolize this topic is a bit older but thought it would be worth letting you all know that installing orical's Java is way easier on Android running Linux. I've been at it awile and have a script set up to fully install the soft float version of JDK 7 and am working on a downloader script (it is actually a tall order reliably downloading the source from orical reliably) to incorperate in when debugged. Eventually I'll be testing/writing one for hard float versions too but for now you all can find what has been tested as working with "Debian Kit" from here https://github.com/S0AndS0/Debian-Kit-Mods check the readme for how to modify for your preferred version of Java and enjoy
Update 02272014- the java downloading script I mentioned earlier is now ready for testing; you may use it to download jre or jdk either hard float or soft float (4 options) and the installer script has been updated for soft float jdk version 7u51. I'll be working on making the download script call up the installer scripts today too
Update 03032014- try the "ARM_Linux_Mods" script in the above github; it will step you through the download and installation of Java JDK soft or hard float.

I'm working on AOSP. I copied all extracted tar file to somewhere inside system folder. When I type
Code:
java -version
It says:
Code:
/system/bin/sh: java: No such file or directory
But it exist!
In other side, I typed
Code:
ln -s /system/ejre1.6.0_25/bin/java /usr/bin/java
and it said:
Code:
4 /system/linux_arm_sflt/jre/bin/java 4 /system/bin/java
What should I do now?
UPDATE:
When I run java directly Or symbolink), it says:
Code:
/system/bin/sh: java: can't execute: Permission denied
And when I run it with busybox, it says:
Code:
java: applet not found
UPDATE:
Even when I root my device, I get above errors.

you have to run Java in a Linux chroot.
Android shell can't handle it (system/bin/sh is definitely Android path)

What do you mean by run it in a Linux chroot?
If you means run it after type SU command, I did.
I root my device, then I can use su command in shell.
But if you means something else, please explain more in detail.
Thanks.

here's an example of how to use a chroot for Nexus 10
you can also look up lil debi, linuxonandroid, and variations of "chroot (debian, Ubuntu) on Android" with Google, for more information.

All of these installed a virtual Linux that can access with VNC!
But I want to put java binary and its libraries in my Android source, and compile it; then run my jar file with for wxampel installed terminal amulator.apk, or from PC (adb shell command).
Is that possible?

probably not. the Java binary relies on Linux libraries, like libc instead of bionic. not seen anything about running Java under Android except for their dalvik java.

Do you mean if I install a buildroot on my device, or pure linux from first (there is no android on my device anymore), then I can use JRE for armv7 and run a jar with GUI?

I've not had tons of luck getting Linux to run natively on devices, but if you can do it, yes that should work.
i like enlightenment as gui (e17) for debian on mobile device, if you're going that way.
It seems it is not an easy thing to start android development. I followed the official instruction and tried to run the MyFirstApp example from developer.android.com on my Windows 7 64bit machine with AVD. But after 2 days effort, I am still cannot make it work for me in Eclipse and in adb command line.
The best I reached in command line approach is the following -- the second block with italic words shows the error I got:
Code:
E:\Workspace\MyFirstApp>ls bin
AndroidManifest.xml build.prop
AndroidManifest.xml.d classes
MyFirstApp-debug-unaligned.apk classes.dex
MyFirstApp-debug-unaligned.apk.d classes.dex.d
MyFirstApp-debug.apk dexedLibs
MyFirstApp.ap_ proguard.txt
MyFirstApp.ap_.d res
[I][B]E:\Workspace\MyFirstApp>adb install bin\MyFirstApp-debug.apk
failed to copy 'bin\MyFirstApp-debug.apk' to '/data/local/tmp/MyFirstApp-debug.a
pk': No such file or directory
rm failed for /data/local/tmp/MyFirstApp-debug.apk, No such file or directory[/B][/I]
I hope somebody can help me about these:
1. I am in Windows with AVD, why adb want to find /data/local/tmp, which is linux style location?
2. where does the adb try to copy the apk file to? My SDK is installed under "C:\Users\myname\AppData\Local\Android\android-sdk". There is no space in the address path. The source apk file is ready and should not be the cause of that error, I think.
3. Any configuration of the installed SDK needs to be modified in Windows machine? I think the SDK manager should be able to figure out what the machine is and download/install appropriate components for the user. Is that right?
I have similar or the same issue by using Eclipse.
thanks,
