Compiling native programs for Android

There is an excellent tutorial by Nirnimesh on how to compile native programs for Android here http://android-tricks.blogspot.com/2009/02/hello-world-c-program-on-using-android.html

Unfortunately things have changed a bit since last year when this post was written. Andy’s agcc script doesn’t work with the most recent Google NDK release 4B.

I have changed the script a little bit to address new path changes. The new script is available here http://android-cruft.googlecode.com/files/agcc-0.2.tgz.

Make sure to add this to your path

$HOME/AndroidNDK/build/prebuilt/linux-x86/arm-eabi-4.4.0/bin/

where AndroidNDK is your NDK installation directory.

Hope this works for you.
