Too Long; Didn't Read
The Profiler is one of the most powerful tools in Android Studio. It allows you to look inside a running application to detect problems. It is integrated into Android Studio and can be easily easily accessed by clicking a button 50 times. The last method will stop the thread for 2000 ms. The point of this example is to clearly see how Profiler works, specifically the stack of methods it calls, how long they take and what effect they have on the processor. After launching, you may see a pretty deep (50 pieces) and pretty wide (2000ms) stack.
