I’m not particularly experienced with Assembly and ARM, but I was able to write a few routines in it and I’d like to see how they run on an ARM-equipped Android device (Nexus S). What is the procedure for including an Assembly code file into an Android project? Can I only call it from native code, or from Java also?
You can call assembly from Android using the Java Native Interface and the Android NDK.
Cedric mentions using the asm keyword, while I prefer to include assembly source code. I have posted a tutorial to do this at my site: http://www.eggwall.com/2011/09/android-arm-assembly-calling-assembly.html
You can download the source code for my example and see how it works. Once you see a functioning example, it is easy to modify it to your needs.
