📜 Description

FirstDrawDoneListener now removes itself by posting the removal to the main thread. Before, it waited for the next global layout.

💡 Motivation and Context

You can't remove an OnDrawListener from inside onDraw (API 26+ throws). So the listener registered an OnGlobalLayoutListener and removed itself from there. But a draw isn't always followed by a layout pass. On a static screen, the listener stayed registered and ran on every frame (as a no-op), and it kept its callback reachable. That callback captures ActivityLifecycleIntegration and the ttid/ttfd spans. ActivityLifecycleIntegration registers a new listener on every onActivityResumed, so these could pile up on the decor view until the next layout.

It isn't a memory leak: everything is only reachable from the decor view's ViewTreeObserver and dies with the activity. The fix makes the removal happen every time and drops the extra layout listener.

💚 How did you test it?

Updated FirstDrawDoneListenerTest: the listener is now removed after onDraw without any layout pass.
