Android

Install dependencies

  • libogg: Download and unzip it in dependencies/android/libogg.

  • libtheora: Download and unzip it in dependencies/android/libtheora.

  • Ensure the symbolic links in [root]/android/app/jni are correct:

    • RSDKv5 -> root of the RSDKv5 repository

    • Game -> root of the Mania repository (or any other game that you may be compiling)

    • Extra symbolic links can be added for things like mods, as mods do not use the local files for logic. Just ensure that there are CMakeLists.txt files at the root of them.

      To add symbolic links, do the following:

      • Windows: mklink /d "[name-of-symlink]" "[path]"
      • Linux: ln -s "[path]" "[name-of-symlink]"

  • Open [root]/android/ in Android Studio, install the NDK and everything else that it asks for, and build.

The working directory will be at [sdcard root]/RSDK/v5. Please note that GL shaders are required, or you will get a black screen. Read the Shaders section in the OGL README for a guide on how to install them.

Common build issues (Windows)

make: *** INTERNAL: readdir: No such file or directory

Delete android/app/build and try again. This occurs when the path is short enough to build, but too long for a rebuild.

make: Interrupt/exception caught (code = 0xc0000005)

Your paths are too long. Try renaming the symbolic links to something shorter, or make a symbolic link to RSDKv5 closer to the root of the drive and open the project through there (e.x. C:/RSDKv5/android). I haven't had either issue since I did this.

Known issues

These issues will not be fixed here as they are minor, but feel free to have a look at them for yourself in a fork!

Audio device doesn't disconnect properly

The audio callback for the lost stream will continue to fire (AAudioDevice's AudioCallback) so you only end up hearing half on the new stream. All examples I (RMG) looked at while porting didn't show any issues or workarounds for this. I tried to remedy by checking the stream's pointer, but that didn't fix anything.
