In build.gradle (app):

...
compile('com.crashlytics.sdk.android:crashlytics:2.7.1@aar') {
    transitive = true
    exclude group: 'com.android.support', module: 'support-annotations'
    exclude group: 'io.fabric.sdk.android', module: 'fabric'
}
...

Can anyone help me with this ?

Answer 1

Okay.. Removing exclude lines worked for me:

compile('com.crashlytics.sdk.android:crashlytics:2.7.1@aar') {
    transitive = true
    exclude group: 'com.android.support', module: 'support-annotations'
}

Answer 2

I fixed this by moving the Multidex.install() to attachBaseContext(Context base). I had it in onCreate() of the Application

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}
