Measure Android App Performance. From my own android game, frame time can be measured with android.os.systemclock.that is, you call systemclock.elapsedrealtime() once per frame and subtract the value from the previous frame. Systrace allows to measure the performance directly at kernel level.
The collected performance data for each trace are called metrics and vary depending on the type of trace. React native is compelling from a performance standpoint, but as of now the framework does not give developers a solid way to measure the speed of the apps they’re testing. As it is understood from its name, it indicates the number of users on a daily basis.
For example, when an instance of your app issues a network request, the trace collects metrics that are important for network.
That way, android app developers can gain a true understanding of how their android apps will perform on a given device as the end users would perceive them. Galaxy note 5/6/7/8/9 and galaxy s6/7/8/9/10. Now, you can use the same benchmark to test your android phone or tablet. The android profiler section in android studio 3.0 and higher replaces the android monitor tools.
