Enable easy compilation of cmake projects on Android.
By using this android toolchain, the projects will be set up to compile the specified project targeting an Android platform, depending on its input. Furthermore, if desired, an APK can be directly generated by using the androiddeployqt tool.
Note
This module requires CMake 3.1.
Since 1.7.0.
To use this file, you need to set the CMAKE_TOOLCHAIN_FILE to point to AndroidToolchain.cmake on the command line:
cmake -DCMAKE_TOOLCHAIN_FILE=/usr/share/ECM/toolchain/AndroidToolchain.cmake
You will also need to provide the locations of the Android NDK and SDK. This can be done on the commandline or with environment variables; in either case the variable names are:
Additional options are specified as cache variables (eg: on the command line):
After building the application, you will need to generate an APK that can be deployed to an Android device. This module integrates androiddeployqt support to help with this for Qt-based projects. To enable this, set the QTANDROID_EXPORTED_TARGET variable to the target you wish to export as an APK, as well as ANDROID_APK_DIR to a directory containing some basic information. This will create a create-apk-<target> target that will generate the APK file. See the Qt on Android deployment documentation for more information.
For example, you could do:
cmake \
-DCMAKE_TOOLCHAIN_FILE=/usr/share/ECM/toolchain/AndroidToolchain.cmake \
-DQTANDROID_EXPORTED_TARGET=myapp \
-DANDROID_APK_DIR=myapp-apk
make
make create-apk-myapp
The APK would then be found in myapp_build_apk/bin in the build directory.
