title: Crashlytics on Libgdx
body: <p>I am trying to use Fabric on my current Game Project which is based on Libgdx Framework. I am not sure where should I put instruction codes to which gradle file.<br></p>
  
  <pre><code>buildscript {
    repositories {
      maven { url 'https://maven.fabric.io/public' }
    }
  
    dependencies {
      // These docs use an open ended version so that our plugin
      // can be updated quickly in response to Android tooling updates
  
      // We recommend changing it to the latest version from our changelog:
      // https://docs.fabric.io/android/changelog.html#fabric-gradle-plugin
      classpath 'io.fabric.tools:gradle:1.+'
    }
  }
  </code></pre>
  
  <p>First of all this buildscript block exists in build gradle of Project, not for android. Since I put these into parent gradle file, android gradle file can not recognize the library.</p>
  
  <pre><code>apply plugin: 'io.fabric'
  
  repositories {
    maven { url 'https://maven.fabric.io/public' }
  }
  
  
  
  compile('com.crashlytics.sdk.android:crashlytics:2.6.8@aar') {
      transitive = true;
    }
  </code></pre>
  
  <p>I can only add these code blocks into the whole gradle file again which is shown below.</p>
  
  <pre><code>project(":android") {
      apply plugin: "android"
  
      configurations { natives }
  
      dependencies {
          compile project(":core")
          compile "com.badlogicgames.gdx:gdx-backend-android:$gdxVersion"
          natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-armeabi"
          natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-armeabi-v7a"
          natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-arm64-v8a"
          natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-x86"
          natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-x86_64"
          compile "com.badlogicgames.gdx:gdx-box2d:$gdxVersion"
          natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-armeabi"
          natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-armeabi-v7a"
          natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-arm64-v8a"
          natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-x86"
          natives "com.badlogicgames.gdx:gdx-box2d-platform:$gdxVersion:natives-x86_64"
  
      }
  }
  </code></pre>
  
  <p>Could you help me to use Fabric into my game properly?</p>
