Closing this pull request as it tries to hack, but not to resolve the problems below:

• What exactly do we want to measure of the launch of Android application?" - the pull request doesn't give an answer to this question. It moves raising of displayedEvent later, but this does not guarantee that it will include the drawing of all elements in the application. For example, the ListView draws its elements async, so some of them take part of the displayedEvent, but not all. In order to count on the displayEvenet approach, we would need to draw all the native elements sync.

• rootView._onAttachedToWindow() is hijacked only for the case when the root of the application is Frame. We would need a more general approach for all the scenarios.

Attached the timeline-view times - please remove the .log extension in order to preview:
