* Say hello to Qt Android Sensors based on NDK APIBogDan Vatra2019-04-111-63/+0
| | | | | | | | | | | | | | | 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.

* Use qRadiansToDegrees() and qDegreesToRadians() more widelyEdward Welbourne2017-03-061-4/+4
| | | | | | | | | They document intent more clearly than arithmetic with pi does. Also eliminate some hand-rolled RADIANS_TO_DEGREES constants in favor of calling qRadiansToDegrees(). Change-Id: I7ca5e876b3591433bf681b56ad51c4cb409ac59f Reviewed-by: Lorn Potter <lorn.potter@gmail.com>

* Update copyright headersJani Heikkinen2015-02-171-6/+6
| | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Change-Id: I141862df4ed2475c05ebbeb8fe447c4a6e736849 Reviewed-by: Antti Kokko <antti.kokko@theqtcompany.com>
