    Description

      When building a multi-abi APK in Windows, using CMake with:

      QT_ANDROID_ABIS "armeabi-v7a;arm64-v8a"

      Then the resulting APK is broken. In particular, when I browse the APK for resources.arsc (using Android Studio), I see there is an "array" block with the property "load_local_libs". Looking at the contents, I see that "libplugins_multimedia_ffmpegmediaplugin_arm64-v8a.so" is only present for one of the ABIs.

      The result is that you cannot use the camera on the secondary platform, i.e. if you built with arm64-v8a, then the camera will fail to load on armv7 devices. All other functionality seems to work though.
