Answer 1

I had this issue recently, the reason was the version difference:

'com.google.firebase:firebase-ads:9.0.6'

'com.google.firebase:firebase-crash:11.0.2'

so make sure you have the same version.

Answer 2

Firebase Android SDKs now have independent version numbers, allowing for more frequent, flexible updates.

Update all your Firebase dependencies to the latest version (as of 2 May 2018):

 Firebase Core          com.google.firebase:firebase-core:15.0.2
    Ads                 com.google.firebase:firebase-ads:15.0.0
  Analytics             com.google.firebase:firebase-analytics:15.0.2
 App Indexing           com.google.firebase:firebase-appindexing:15.0.0
 Authentication         com.google.firebase:firebase-auth:15.1.0
Cloud Firestore         com.google.firebase:firebase-firestore:16.0.0
Cloud Functions         com.google.firebase:firebase-functions:15.0.0
Cloud Messaging         com.google.firebase:firebase-messaging:15.0.2
Cloud Storage           com.google.firebase:firebase-storage:15.0.2
Crash Reporting         com.google.firebase:firebase-crash:15.0.2
Crashlytics             com.crashlytics.sdk.android:crashlytics:2.9.1
Invites                 com.google.firebase:firebase-invites:15.0.2

I had the same problem but mine was cause by firebase-ui newest version 2.0.0. So I downgraded to 1.2.0 and added the following line to Project level build.gradle file:

allprojects {
    repositories {
        jcenter()

        // Add the following code
        maven {
            url 'https://maven.fabric.io/public'
        }
    }
}

Answer 4

I encountered the same issue after manually adding Firebase to my app.
For me the solution was changing:

classpath 'com.google.gms:google-services:3.2.0'

to:

classpath 'com.google.gms:google-services:3.0.0'

in the root-level build.gradle file.

I had a similar problem after building using phonegap/cordova: com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/internal/zzsk;

I fixed it by editing build.gradle(module Android), as I had 2 libraries that should have the exact same version with different version numbers (8.4.0 and 9.2.1 in my case)

dependencies{
....
//make sure are both same version (8.4.0 or 9.2.1 in my case)
compile 'com.google.android.gms:play-services-gcm:9.2.1'
// this is the one I changed:  compile 'com.google.android.gms:play-services-location:8.4.0'
compile 'com.google.android.gms:play-services-location:9.2.1' // it was 8.4.0
....
}

Answer 6

If anyone had the same issues as mine, I removed the firebase-core dependency and it worked like a charm.

dependencies{
    implementation 'com.google.firebase:firebase-core:15.0.0'
    implementation 'com.google.android.gms:play-services-ads:15.0.0'
    implementation 'com.google.firebase:firebase-crash:15.0.0'
    implementation 'com.google.firebase:firebase-messaging:15.0.0'
}

to

dependencies{
    implementation 'com.google.android.gms:play-services-ads:15.0.0'
    implementation 'com.google.firebase:firebase-crash:15.0.0'
    implementation 'com.google.firebase:firebase-messaging:15.0.0'
}
