Class DefaultAndroidProfiler

java.lang.Object
com.jme3.app.DefaultAndroidProfiler
All Implemented Interfaces:
AppProfiler
public class DefaultAndroidProfiler extends Object implements AppProfiler
An AppProfiler implementation that integrates the per-frame application-wide timings for update versus render into the Android systrace utility.

This profiler uses the Android Trace class which is only supported on Android SDK rev 18 and higher (ver 4.3 and higher). If the device is running a version less than rev 18, the logging will be skipped.

In the MainActivity class, add the following:


  @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      app.setAppProfiler(new DefaultAndroidProfiler());
  }
Start the Android systrace utility and run the application to see the detailed timings of the application.
