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 ?

回答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'
}

回答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);
}

Please Check this configure. I have used this.

in App Gradle

    apply plugin: 'io.fabric'

    compile('com.crashlytics.sdk.android:crashlytics:2.8.0@aar') {
        transitive = true;
    }
    compile('com.crashlytics.sdk.android:answers:1.4.1@aar') {
        transitive = true;
    }
    compile('io.fabric.sdk.android:fabric:1.4.1@aar') {
        transitive = true;
    }

Project Gradle

buildscript {
repositories {
        jcenter()
        mavenLocal()
        maven { url 'https://maven.fabric.io/public' }

    }
dependencies {
classpath 'io.fabric.tools:gradle:1.+'
  }
}

it's working for me as well. You can try this
