Where to find my Android app native code on my test server?

Although there are similar questions such as A, B and C, none of them answer my question.

I downloaded Android 4.3 source code, compiled and ran it on a Ubuntu test server. I developed a small Android app using only Java on my PC then ran it on the test server.

My question:

Where to find the Android app native code (after compiling the bytecode) on my test server (file path and file name)?
