Yeah, I shuffled the prints around a bit, so that it'll be a bit more clear.

Description
Before my refactoring of
ProcessUtils, when the Android emulator process failed, we would throw and catch the error as a string and print it. After my refactoring ofProcessUtilsthe error was thrown as aProcessExceptionbut the code to catch the exception wasn't updated. This resulted in the Android emulator process failures crashing the tool instead of beingToolExits as was intended.Only the Android emulator code was using the String based throw/catch. This PR removes that, and refactors the emulator process management code to print errors instead of relying on exceptions.
