The Systrace tool helps analyze the performance of your application by capturing and displaying execution times of your applications processes and other Android system processes. The tool combines data from the Android kernel such as the CPU scheduler, disk activity, and application threads to generate an HTML report that shows an overall picture of an Android device’s system processes for a given period of time.
The Systrace tool is particularly useful in diagnosing display problems where an application is slow to draw or stutters while displaying motion or animation. For more information on how to use Systrace, see Analyzing Display and Performance.
