I am trying to add firebase in my project but when I implement \'com.google.firebase:firebase-messaging:19.0.0\' and \'com.google.firebase:firebase-core:1
\'com.google.firebase:firebase-messaging:19.0.0\'
\'com.google.firebase:firebase-core:1
Try this and sync your project, if this can help you
implementation 'com.android.support:appcompat-v7:28.0.0' implementation 'com.android.support:support-v4:28.0.0'
