}
This problem showed up on api 22 device (android 5.1.1) and on api 23 emulator device while the app worked fine on api 26 and on api 25.

Please try to use the latest version 28.0.0 not 28.0.0-alpha1. Please change those and try again like this
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
instead of
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support:design:28.0.0-alpha1'
implementation 'com.android.support:recyclerview-v7:28.0.0-alpha1'
