Android NDK release flag

Issue

I'm using the Android NDK (integrated with CMake and gradle). Currently the C++ Release-Flag is automatically set dependent on the Android Build-Type (Release/Debug). I'd like to compile/link the native code always with the release flag. How can this be done?

Thank you

Solution

Inside the module build.gradle (for example, app/build.gradle), inside android {} block, add:

android {
   ...
    externalNativeBuild {
        cmake {
            arguments "-DCMAKE_BUILD_TYPE=Release"
        }
    }
}

This would overwrite the default debug settings as arguments are appended to default settings. Check the generated build files at .externalNativeBuild/cmake/debug/$arch :

• cmake_build_command.txt
• android_gradle_build.json
