Attributes

Remarks

Report to the system that your app is now fully drawn, for diagnostic and optimization purposes. The system may adjust optimizations to prioritize work that happens before reportFullyDrawn is called, to improve app startup. Misrepresenting the startup window by calling reportFullyDrawn too late or too early may decrease application and startup performance.

This is also used to help instrument application launch times, so that the app can report when it is fully in a usable state; without this, the only thing the system itself can determine is the point at which the activity's window is <em>first</em> drawn and displayed. To participate in app launch time measurement, you should always call this method after first launch (when #onCreate(android.os.Bundle) is called), at the point where you have entirely drawn your UI and populated with all of the significant data. You can safely call this method any time after first launch as well, in which case it will simply be ignored.

If this method is called before the activity's window is <em>first</em> drawn and displayed as measured by the system, the reported time here will be shifted to the system measured time.
