The project is still at an early stage so expect to find idiosyncrasies along the way. In order to build this project, you must install the Android SDK/NDK and set-up the ANDROID_HOME environment variable. Run the following commands after checking out the repository to build the APK.
$ mkdir build; cd build
$ ../etc/gen_cmake_android.sh ..
$ make
The resulting APK is located in external/lovr/lovr.apk. The APK name will be renamed in a future diff.
As of right now, I am only testing Point Blank on PSX with the PCSX rearmed core. As a matter of fact, it's hardcoded in project/main.lua. If you want to play with something else you'll need to change this file.
Cores can be downloaded from the libretro nightly builds: http://buildbot.libretro.com/nightly/android/latest/arm64-v8a/
Then adb push the core and game into the application apk folder.
./etc contains general scripts and manifests
./external contains sub-repositories (e.g., lovr)
./plugins contains lovr plugins (e.g., libretro)
./project contains main source of the project and its assets
