How the port works
================================================================================
- Android applications are Java-based, optionally with parts written in C
- As SDL apps are C-based, we use a small Java shim that uses JNI to talk to
the SDL library
- This means that your application C code must be placed inside an android
Java project, along with some C support code that communicates with Java
- This eventually produces a standard Android .apk package

Building an app
================================================================================
Instructions: Instructions:
1. Edit android/config.cfg to point to the location of the NDK 1. Edit android/config.cfg to point to the location of the NDK
2. Run 'make -f Makefile.android'. If all goes well, libsdl.a should be created 2. Run 'make -f Makefile.android'. If all goes well, libsdl.a should be created
3. Place your application source files in android/testproject/jni 3. Place your application source files in android/project/jni
4. Run 'ndk-build' (a script provided by the NDK). This compiles the C source 4. Edit the Android.mk to include your source files
4. Run 'ant' in android/testproject. This compiles the .java and eventually 5. Run 'ndk-build' (a script provided by the NDK). This compiles the C source
6. Run 'ant' in android/testproject. This compiles the .java and eventually
creates a .apk with the C source embedded creates a .apk with the C source embedded
6. 'ant install' will push the apk to the device or emulator (if connected) 7. 'ant install' will push the apk to the device or emulator (if connected)

Known issues

- SDL audio (although it's mostly written, just not working properly yet)
- TODO. I'm sure there's a bunch more stuff I haven't thought of
