Prerequisites for build process

To compile OSG as a standalone library you'll only need the Android NDK. To develop applications with the library you'll also need the Android SDK

• Android SDK: http://developer.android.com/sdk/index.html
• Android NDK: http://developer.android.com/sdk/ndk/index.html

Once downloaded the NDK a new Toolchain has been provided in OSG to build using CMake:

 

mkdir build_android_static_gles2 && cd build_android_static_gles2
cmake .. -DANDROID_NDK=<path-to-the-android-ndk> -DCMAKE_TOOLCHAIN_FILE=../PlatformSpecifics/Android/android.toolchain.cmake  \
         -DOPENGL_PROFILE="GLES2" -DDYNAMIC_OPENTHREADS=OFF -DDYNAMIC_OPENSCENEGRAPH=OFF \
         -DANDROID_NATIVE_API_LEVEL=15 \
         -DANDROID_ABI=armeabi \
         -DCMAKE_INSTALL_PREFIX=<path-to-the-install-path> 
make -j 8
make install

• The OPENGL_PROFILE works as expected, changing it to "GLES1" it builds and links OSG using GLES1
• The DYNAMIC_OPENTHREADS/DYNAMIC_OPENSCENEGRAPH parameters also allows to build the dynamic libraries
• ANDROID_NATIVE_API_LEVEL, ANDROID_ABI are optional and should be changed accordingly to your target device
