Whenever possible (i.e. any API != 28), we'll now detect the end of a frame by spying on main thread messages and running code right when the main thread message is done running and before a new main thread message starts running, by leveraging Looper.getMainLooper().setMessageLogging { }. We're also detecting whether we're in a frame or not by looking at the name of the runnable, rather than by creating a stacktrace.
Non backward compatible API changes
Renamed MainThreadMessageSpy.startTracing() and MainThreadMessageSpy.stopTracing() to MainThreadMessageSpy.addTracer() and MainThreadMessageSpy.removeTracer().
New APIs
MainThreadMessageSpy.startSpyingMainThreadDispatching() and MainThreadMessageSpy.stopSpyingMainThreadDispatching(), MainThreadMessageSpy.currentMessageAsString, MainThreadMessageSpy.enabled and MainThreadMessageSpy.onCurrentMessageFinished()
MainThreadMessageScopedLazy (prop by mainThreadMessageScopedLazy {}) property for main thread scoped lazy properties that get cleared at the end of each main thread message.
Choreographers.postOnFrameRendered(), Choreographers.postOnWindowFrameRendered() and Choreographers.isInChoreographerFrame
InputEventTrigger.rendered, InputEventTrigger.renderedUptime and InputEventTrigger.onInputEventFrameRendered
