From 2c9fc2c1a197b84ba9ef3dc4e586a77a18c3dcc5 Mon Sep 17 00:00:00 2001 From: BogDan Vatra Date: Tue, 2 Apr 2019 14:00:37 +0300 Subject: Say hello to Qt Android Sensors based on NDK API 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.
