Question

In project \'app\' a resolved Google Play serv

Answer 1

I resolved it by simply clearing the app-level dependencies block leaving just the default Android dependencies like so:

dependencies {
  testImplementation 'junit:junit:4.12'
  androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
  androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
  implementation 'androidx.multidex:multidex:2.0.0'
}

The working solution for me was to remove "firebase-auth" and add "firebase-core" dependency. But after a couple of project rebuilds I started experiencing another compilation issue so I had to add the "firebase-auth" dependency in addition to the "firebase-core" in order to make it work:

implementation 'com.google.firebase:firebase-auth:19.0.0'
implementation 'com.google.firebase:firebase-core:17.0.1'
implementation 'com.firebaseui:firebase-ui-auth:4.3.1'

Answer 3

The problem was it was missing a dependency. Adding com.google.firebase:firebase-auth solved the issue.

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.firebase:firebase-firestore:17.1.5'

//    implementation'com.google.firebase:firebase-core:16.0.6'
//    implementation'com.google.firebase:firebase-storage:16.0.5'

    implementation'com.google.firebase:firebase-auth:16.1.0' => add this line
    implementation 'com.firebaseui:firebase-ui-auth:4.2.0'
}

The problem was fixed after upgrading this lib in my project's build.gradle:

classpath 'com.google.gms:google-services:4.3.3'

and these ones in the app module's build.gradle:

implementation 'com.google.firebase:firebase-core:17.3.0'
implementation 'com.google.firebase:firebase-messaging:20.1.5'

After this, use Android Studio's Clean menu

The ML Kit library had versioning problems in the latest release.

Google Play services library dependency depends on another at an exact version error (thrown by the google-services plugin)

Here is the link to the solution. https://firebase.google.com/support/release-notes/android#bom_v25-8-0

Answer 6

There was a bug related to google-services that was eventually fixed in version 4.3.3.

So you can either use 4.3.3 or the latest version (check here)

classpath 'com.google.gms:google-services:4.3.3' // or latest version

or downgrade to 4.1.0

classpath 'com.google.gms:google-services:4.1.0'
