Fabric is a modular mobile platform that provides useful kits you can mix to build your application. Crashlytics is a crash and issue reporting tool provided by Fabric that allows you to track and monitor your applications in detail.

How to Configure Fabric-Crashlytics

Step 1: Change your build.gradle:

Add the plugin repo and the gradle plugin:

buildscript {
 repositories {
   maven { url '<https://maven.fabric.io/public>' }
 }

 dependencies {
   // The Fabric Gradle plugin uses an open ended version to react
   // quickly to Android tooling updates
   classpath 'io.fabric.tools:gradle:1.+'
 }
}

Apply the plugin:

apply plugin: 'com.android.application'
//Put Fabric plugin after Android plugin
apply plugin: 'io.fabric'

Add the Fabric repo:

repositories {
  maven { url '<https://maven.fabric.io/public>' }
}

Add the Crashlyrics Kit:

dependencies {
  
  compile('com.crashlytics.sdk.android:crashlytics:2.6.6@aar') {
    transitive = true;
  }
}

Step 2: Add Your API Key and the INTERNET permission in AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="<http://schemas.android.com/apk/res/android>">
  <application
     ... >
      
      <meta-data
          android:name="io.fabric.ApiKey"
          android:value="25eeca3bb31cd41577e097cabd1ab9eee9da151d"
          />

  </application>
  
  <uses-permission android:name="android.permission.INTERNET" />
</manifest>

Step 3: Init the Kit at runtime in you code, for example:

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      //Init the KIT
      Fabric.with(this, new Crashlytics());

      setContentView(R.layout.activity_main);
    }
}

Step 4: Build project. To build and run:
