Working for Android

To build your raylib game for Android you need a set of Android tools. Those tools are basically the Android SDK and Android NDK, including Android Platform Tools and also Java Runtime.

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.
