This is Alien Blaster game ported to Google Android (original sources: http://www.schwardtnet.de/alienblaster/ ).
I did not change anything in Alien Blaster sources, except for SCREEN_WIDTH,
SCREEN_HEIGHT and BIT_DEPTH constants in global.h, to support 320x430x16bpp video mode,
and also made audio initialize after main() has been called, not inside static initializers (ugh)

Then you can test it by launching Alien Blaster icon from Android applications menu.

Currently you have to copy your application data by hand using "adb push" (it can copy directories too),
into the path specified in project/jni/Android.mk:10,
in the future I'll add some handler to Java sources that downloads data from Internet and
puts it into given folder before executing main code.
Application data is not bundled with app itself - it should be downloaded from net on first run.
Create .ZIP file with your application data, and put it somewhere on HTTP server,
then replace project/src/DemoActivity.java:73 with download URL.
If your app data is bigger than 5 megabytes it's better to store it on SD card -
set DownloadToSdcard variable to true in project/src/DemoActivity.java:78,
and set appropriate path in project/jni/Android.mk:10
(I did not test the code with SD card, so it may fail)
If you'll add new libs add them to project/jni/, copy Android.mk from existing lib, and
add libname to Application.mk and project/jni/<yourapp>/Android.mk
