Track screen load duration

[orhanobut]

Problem

Sometimes you may need to determine the elapsed time for a specific event. For example: Screen load time between onResume and onCreate

Proposition

Add a track timer annotation to start point with a key. Key will be used to differentiate different timer points. Thus multiple timer start point can be used. And used a specific annotation to add the attribute which gets the attribute key and the timer to determine elapsed time.

@TrackTimer("timer_id")
public void onCreate() {}

@TrackEvent("Event name")
@TrackAttribute(key="attribute", timer="timer_id")
public void onResume(){}

onResume will have an attribute which is called "attribute" and the value will be elapsed time between onCreate and onTime.

Elapsed time should use milliseconds for unit.

does this work in the source yet?

No, not yet. I dropped the idea actually until I have a concrete need. Since analytic provides calculate the lead time already. Do you have any concrete example?
