The google cloud integration was working fine but suddenly stopped.
Here is the error I receive
ERROR: (gcloud.beta.test.android.run) [app/build/outputs/apk/app-debug-androidTest-unaligned.apk] not found or not accessible
The anligned APK was not found but the app-debug.apk was uploaded successfully.
The only change I made was updating gradle to 2.2.0.
