Imagine that you, and your new Pixel device, have gone back in time to 1980.
Lucky for you, your friend Marty mcFly, the developer of "WatchStarWars" application, and you're just about to watch "Episode V", you're about to watch it for the 1st time.
WatchStarWars app has a single activity, WatchStarwarsActivity.
It's an activity with one button "Say Something", that when clicked, logs an interesting fact about the movie to the log, a fact that, if you haven't watched Episode V, you might find to be a spoiler.
In its OnCreate method, WatchStarwarsActivity posts-delayed a "Finished Watching Starwars" log message for x milliseconds.
Marty loves technology. He uses Timber for injecting a testable log into the activity with Dagger. He is also a very pragmatic developer - he tests his app with Espresso, with this scenario:
Open the activity
