Today I wanted to generate an APK from my app but i got the following error:
Observed package id \'add-ons;addon-google_apis-google-19\' in inconsistent loca
This is caused by upgrading SDK which has some changes in package names. Since this is just a warning, it could safely be ignored.
Anyway, to remove the warning,remove all Android SDK Build Tools 19.x. It should only show Android SDK Buld Tools 19.1 afterward. Install that version
back, and you should be good to go.
