How can i run C binary (executable file) in Android from Android Shell

[Sam Jona]

I have Android-embedded Device on which i installed Android
Gingerbread 2.3.4 Here i want to run C executable file on android
device

I am able to run android NDK application on Device and its run perfect
But i want to run only one hello.c executable file on Device directly.

/* #includes #defines ... */

int main(){
// Do something when this is executed
return 0;
}

Is there any way to compile this file with Android NDK tool chain and
we can run this file's executable.

I found one thing http://my.opera.com/otaku_2r/blog/build-and-run-c-application-on-android

but this is not working for me i am using Android NDK, Revision 7b of
linux There is no directory structure like this

/data/local
# ./hello
/system/bin/sh: ./hello: not found

I also tried this /system/bin/hello but cant able to run this Binary
file.

Thanks. Any help Will be appreciated.

Did you set the right permissions for the executable? (e.g.   chmod 777 hello)

Your phone must be rooted and you need to run your file from the directory you pushed it to.

Ex:  adb push hello /data/local
       adb shell
       cd /data/local
       ./hello

Not true.  Running executable is discouraged, but not prevented in stock releases.  Root is not required.

It is also entirely possible to run one from a different directory than the current by specifying the path.

But it's debatable if this is even on topic for the ndk group.

you should compile you bin with -static

Here go my steps:

 

1. write a C program testEXE.c and build into an executable file "testEXE".

// testEXE.c

#include <stdio.h>

int main() {

   printf("Hello. Test succeeded.");

}

 

2. On PC, with Android SDK installed, run "cmd" (Command Prompt)

 

> cd C:\android-sdk\platform-tools   (my sdk folder is c:\android-sdk)

> adb push testEXE /sdcard/

> adb shell

$ cd /data/local

$ mkdir tmp

$ cat /sdcard/testEXE > /data/local/tmp/testEXE

$ cd /data/local/tmp

$ chmod 751 testEXE

 

3. then, on the android phone, tap to launch the "Android Terminal Emulator"

$ cd /data/local/tmp

$ ./testEXE

You should be able to see it working now.

See http://stackoverflow.com/questions/17383552/how-to-package-native-commandline-application-in-apk - there I show how you can easily package your native (C) executable file with your APK, so that the usual installer does all heavy lifting for you.
