Answer 1

For me it worked just File->Invalidate Cache/Restart, so do Invalidate and Restart.

Answer 2

I just updated the crashlytics:2.5.5@aar to crashlytics:2.6.4@aar. It works of me.

dependencies {
        compile('com.crashlytics.sdk.android:crashlytics:2.6.4@aar') {
            transitive = true;
        }
    }

Check the latest code : https://fabric.io/kits/android/crashlytics/install

Answer 3

I had the same issue, my problem was that I was offline. I realised looking at the error message:

Could not GET 'https://maven.fabric.io/public/io/fabric/tools/gradle/maven-metadata.xml'.
maven.fabric.io: unknown error

So going online, cleaning, build, run... worked for me.

Answer 4

For me i did not add maven { url 'https://maven.fabric.io/public' } to my repo

repositories {
    maven { url 'https://maven.fabric.io/public' }
    mavenCentral()
}

Just in case someone is still experiencing the same issue.

Answer 5

I had the same issue - it just stopped working. Problem has resolved by itself after I logged into my account at http://fabric.io/.
