In the SDL2-2.0.1 there is the android project. Copy it and its contents 
to another location. Rename the folder to media. change into the jni 
folder. Now copy the SDL2-2.0.1, SDL2_image, and SDL2_mixer to the
jni folder. Rename the SDL2-2.0.1 to SDL2. 

Edit jni/Application.mk and uncomment 
APP_STL := stlport_static

jni/src/Android.mk

SDL_PATH := ../SDL2

SDL_IMAGE_PATH := ../SDL2_image

SDL_MIXER_PATH := ../SDL2_mixer

LOCAL_C_INCLUDES := $(LOCAL_PATH)/$(SDL_PATH)/include $(LOCAL_PATH)/$(SDL_IMAGE_PATH) $(LOCAL_PATH)/$(SDL_MIXER_PATH)

# For the Android.mk for the SDL2_image, change the build to false for webp

# For the Android.mk for the SDL2_mixer, change the build to false for mp3 support

# Make an assets folder in the top level for your graphics and music.
mkdir assets

# copy over the jpg and sound files to the assets file. SDL will know to load them from this folder.

# Now copy over the source files from the madbomber source tree to the jni/src area.

In order to do the C++ cross compiling, do the following:
