All firebase libraries must be either above or bel

Question

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

Answer 1

I have not found the question yet in your question But if you want the latest version of Firebys offices This is compatible with version 27.0.3

//Firebase
implementation 'com.google.firebase:firebase-database:11.8.0'
implementation 'com.google.firebase:firebase-storage:11.8.0'
implementation 'com.google.firebase:firebase-auth:11.8.0'
implementation 'com.firebaseui:firebase-ui-database:2.0.1'
implementation 'com.google.firebase:firebase-messaging:11.8.0'
implementation 'com.google.firebase:firebase-core:11.8.0'

Answer 2

For example change implementation 'com.google.android.gms:play-services-appindexing:9.8.0' to implementation 'com.google.firebase:firebase-appindexing:15.0.1' , as this suggestion comes in the warning in build.gradle.

Answer 3

apply plugin: 'com.google.gms.google-services'

put it under this line.

apply plugin: 'com.android.application'

it worked for me.

Answer 4

Remove this from App level gradle

implementation 'com.google.android.gms:play-services-maps:15.0.0'

and then try these versions

compile 'com.google.firebase:firebase-core:11.8.0'
compile 'com.google.firebase:firebase-messaging:11.8.0'
compile 'com.google.firebase:firebase-database:11.8.0'
compile 'com.google.firebase:firebase-auth:11.8.0'

this one worked for me... tanx

Answer 5

While Changing google or firebase dependency version make sure you update the compatible version in project level gradle too.

Answer 6

Change all of your firebase libraries to the same version.
