//In your build.gradle app module, you will need to add four code snippets.

//1. Add the following buildscript:

buildscript {
  repositories {
    maven { url 'https://maven.fabric.io/public' }
  }
dependencies {
    classpath 'io.fabric.tools:gradle:1.+'
  }
}

//2. Apply the Fabric plugin:
apply plugin: 'io.fabric'

//3. Add the Fabric Maven repository:

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

//4. Add the following to your dependencies:
compile('com.crashlytics.sdk.android:crashlytics:2.6.8@aar') {
    transitive = true;
}

Fabric will add your API key to the Manifest.xml file:

Menifest.xml






<meta-data





    android:name="io.fabric.ApiKey"





    android:value="<YOUR_FABRIC_API_KEY>"





/>












//Request permission for your application to open network sockets:

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

The fabric may force you to create an application file for put Fabric.with(this, new Crashlytics());. You can add it in MainActivity.java manually as well.

Once integration is complete, Crashlytics will start tracking all the crashes happening in the app without any extra code.

Handle Caught Exceptions.
In addition to automatically reporting your app’s crashes, Crashlytics for Android can also log caught exceptions from app’s catch blocks. To log caught exceptions, add Crashlytics.logException() method to your catch block and pass an exception as an argument.

Handle Caught Exceptions.


try {
    JSONObject obj = new JSONObject("something");
}
catch (Exception e) {
    Crashlytics.logException(e);
}

All caught exceptions logged by Crashlyitcs will appear as a non-fatal issue in Fabric dashboard. Your issue summary will contain all the state information.
