It's not been done for a while afaik, I've not compiled the compiler for a long time and I'm rusty on the details. You basically need an arm (--target= you should get this from the equivalent c/c++ compiler in the ndk for the version you are targetting) cross compiler. You then need either a Java startup activity which calls into Ada code or an Ada NativeActivity which binds the C version in the ndk, that will call AdaInit and AdaFinal (think that's the right name). If you need to call into any lib on Android which requires a binding, you need to generate that, so either a C binding or a JNI binding. I have a JNI package on my github which you can use as a start, a tool to get generate the bindings to Java would be required as JNI is really tedious. https://github.com/Lucretia/jni https://github.com/Lucretia/jni/blob/master/tests/test.adb
