I have checked my app build.gradle file and these are the only lines that are related to firebase in them
/***
* Firebase
*/
implementation 'com.google.firebase:firebase-core:15.0.0'
implementation 'com.google.firebase:firebase-messaging:15.0.0'
implementation('com.crashlytics.sdk.android:crashlytics:2.9.1@aar') {
transitive = true
}
implementation 'com.google.firebase:firebase-ads:15.0.0'
I do not have any library that makes use of firebase so I don't think there can be an issue with a library using an older version.
The problem is I can't build gradle, clean project or rebuild project with the new v15 version of firebase as it keeps throwing the error All firebase libraries must be either above or below 14.0.0
