Working for Android

To build your raylib game for Android you need a set of tools for Android. Those tools are basically the Android SDK and Android NDK that can be installed from Android Studio's built in SDK Manager.

Installing Android tools

Step 1. Install Java Runtime 8 (JRE), Android Studio (Android SDK, Android NDK) and Apache Ant tools:

Download and Install Java SE Runtime Environment 8

Download and Install on C: Android Studio. Use Android Studio's SDK Manager to install the latest Android Platform Tools and desired SDKs and NDK.

Download and decompress on C: Apache Ant

Step 2. Create the following environment variables:

Android Studio installs the NDK in a ndk-bundle folder inside the SDK folder location (where ever you installed it).

ANDROID_HOME = C:\android-sdk
ANDROID_SDK_TOOLS = C:\android-sdk\platform-tools
ANDROID_NDK = C:\android-sdk\ndk-bundle
ANT_HOME = C:\apache-ant

Compiling raylib source code

To compile raylib src it's required to install a custom ndk standalone toolchain. Build toolchain with this command:

python %ANDROID_NDK%\build\tools\make_standalone_toolchain.py --arch arm --api 16 --install-dir=C:\android_toolchain_arm_api16

After that, just navigate from command line to folder raylib/src/ and execute Makefile with:

mingw32-make PLATFORM=PLATFORM_ANDROID

Remember to setup ANDROID_NDK, ANDROID_TOOLCHAIN property properly in the Makefile!

ANDROID_NDK = C:/android-sdk/ndk-bundle
ANDROID_TOOLCHAIN = C:/android_toolchain_arm_api16

NOTE: libraylib.a will be generated in folder `raylib/release/android/armeabi-v7a/.

Compiling a raylib game for Android (using an example project template)

Step 1. To build an APK, navigate to folder raylib/template/simple_game/ and edit Makefile.Android. Replace these settings with yours where apropriate:

ANDROID_HOME = C:/android-sdk
ANDROID_NDK = $(ANDROID_HOME)/ndk-bundle
ANDROID_TOOLCHAIN = C:/android_toolchain_arm_api16
ANDROID_BUILD_TOOLS = $(ANDROID_HOME)/build-tools/26.0.3
ANDROID_PLATFORM_TOOLS = $(ANDROID_HOME)/platform-tools
JAVA_HOME = C:/PROGRA~1/Java/jdk1.8.0_152

Then build the apk with:

mingw32-make PLATFORM=PLATFORM_ANDROID

Step 2: To install the APK into connected device (previously intalled drivers and activated USB debug mode on device):

%ANDROID_SDK_TOOLS%\adb install -r simple_game.apk

Step 4: To view log output from device:

%ANDROID_SDK_TOOLS%\adb logcat -c
%ANDROID_SDK_TOOLS%\adb -d  logcat raylib:V *:S

Again, Notepad++ comes with an already prepared script to do that. Just open raylib/templates/simple_game/simple_game.c and run Notepad++ script raylib_compile_android_project_run_log.

If you have any doubt, just let me know.
