This is what my logs tell me.

After seeing this, I manually added an applicationId to the build.gradle file and the application now seems to run, however, push notifications don't seem to work quite yet. I made a connection with PushWoosh and tried sending a notification from my AEM instance (which is on localhost), but nothing really happened afterwards.
