* Say hello to Qt Android Sensors based on NDK APIBogDan Vatra2019-04-111-0/+100
Until Qt 5.9, we had to use JNI way because the NDK sensors API was introduced in API-16. Starting with Qt 5.9 we can safely use the NDK API as API_16 is the minimum API supported by Qt. Using the NDK API instead of JNI boost the performance a lot! The CPU usage dropped 2 to 4 times, from over 60% using the JNI to less than 20%. [ChangeLog][Android] Rewrite Qt Android Sensors using NDK API. Change-Id: If3e3f1e56973e2a189662912b2a6ebfbd71dee14 Reviewed-by: Lorn Potter <>
