This is a simple Android application written in C that displays "Hello, World!" using raylib for graphics rendering.

Before you begin, ensure you have the following installed:

• Android SDK
• Android NDK
• CMake: Version 3.5 or higher for building the project.
• Build System: Ninja is recommended for faster builds.
• Java Development Kit (JDK)
• raylib: Download and build raylib for Android following the instructions in the raylib documentation.

Before building the project, ensure the following environment variables are set:

• ANDROID_HOME: Path to the Android SDK installation.

• ANDROID_EXTERNAL_HOME: Path to the installation of external Android libraries. This directory must have the following structure:

  ANDROID_EXTERNAL_HOME/
  ├── include/              # Contains header files for external libraries
  │   └── raylib.h          # Raylib header files
  └── lib/                  # Contains library files for different ABIs
      ├── <ABI>/            # ABI name (e.g., armeabi-v7a, arm64-v8a)
      │   └── libraylib.a   # Raylib static library for the specified ABI
  

• KEYSTORE_FILE: Path to the keystore file used for signing the APK.

• KEYSTORE_PASS: Password for the keystore.

• KEY_PASS: Password for the signing key within the keystore.

Replace placeholders with your values and execute the commands:

1. Configure the project:

   cmake -B <Build-Directory> \
         -DCMAKE_TOOLCHAIN_FILE=<NDK-Path>/build/cmake/android.toolchain.cmake \
         -DANDROID_ABI=<ABI> \
         -DANDROID_PLATFORM=<API-Level>
   

   Parameters:

   • Build Directory: Name of the build directory (e.g., Build/arm64-v8a).
   • NDK Path: Path to the Android NDK installation.
   • ABI: Target Application Binary Interface (e.g., arm64-v8a, armeabi-v7a).
   • API Level: Minimum Android API level to support (e.g., android-21).

2. Build the project:

   cmake --build <Build-Directory>
   

   This command compiles the native code and generates the APK.

3. Install on a connected device:

   To install the APK on a connected device, run:

   cmake --build <Build-Directory> --target install_apk
   

• Clean: Clean all output files (including binaries and APKs)

  cmake --build <Build-Directory> --target clean
  

• Uninstall APK: Remove the app from the connected device.

  cmake --build <Build-Directory> --target uninstall_apk
  

• Check Device ABI: Confirm the ABI of the connected device.

  cmake --build <Build-Directory> --target check_device_abi
  

• List Users on Device: Get a list of users configured on the device.

  cmake --build <Build-Directory> --target list_users
