Method Tick

native-activity/app/src/main/cpp/main.cpp:158–162

Entry point for Choreographer. The first argument (the frame time) is not used as it is not needed for this sample. If you copy from this sample and make use of that argument, note that there's an API bug: that time is a signed 32-bit nanosecond counter on 32-bit systems, so it will roll over every ~2 seconds. If your minSdkVersion is 29 or higher, use AChoreographer_postFrameCallback64 instead,
