I recently updated to Android Studio 2.3, and now when I try to run the application, the emulator does not come online. It times out after 300 seconds.

Additionally, The app has been experiencing a FATAL EXCEPTION ERROR (OOM), and I am not sure how to fix that either, or if that is part of the emulator problem. 

Any help is much appreciated. Again, my knowledge in the program is very limited so if your answer can be kept simple, that would be great.
