Error = Cannot resolve symbol GoogleCloudMessaging in Android

Question

I am using android studio 1.2.1 and working on push notification service using GCM error is given in intentservice

"Cannot Resolve GoogleCloudMessaging"

Here is code:

Bundle extras = intent.getExtras();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
Log.e("test recieve", "-----Catch");
if (!extras.isEmpty()) {
    if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
            .equals(messageType)) {
        sendNotification("Send error"+ extras.toString());
    } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
            .equals(messageType)) {
        sendNotification("Deleted messages on server: "
                + extras.toString());
    } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
            .equals(messageType)) {
        for (int i = 0; i < 3; i++) {
            Log.i(TAG,
                    "Working... " + (i + 1) + "/5 @ "
                            + SystemClock.elapsedRealtime());
            try {
                Thread.sleep(5000);
            } catch (InterruptedException e) {
            }
        }
        Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());

        sendNotification(""+extras.get(Config.MESSAGE_KEY));
        Log.i(TAG, "Received: " + extras.toString());
    }
}
GCMBroadcastReceiver.completeWakefulIntent(intent);
}

** this is my Build Gradle**

 apply plugin: 'com.android.application'
       android
       {
   compileSdkVersion 22
   buildToolsVersion '22.0.1'
   defaultConfig
        {
     applicationId "insidesoftwares.gcmpush"
      minSdkVersion 16
      targetSdkVersion 22
      versionCode 1
      versionName "1.0"
     }
     buildTypes
        {
        release
            {
          minifyEnabled false
 proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
    }
  }
   }
  dependencies {
  compile 'com.google.android.gms:play-services:7.5.0'
  compile project(path:':backend',configuration: 'android-endpoints')
  compile 'com.nineoldandroids:library:2.4.0'
  compile 'com.google.code.gson:gson:2.2.4'

   }

Please try adding this in your gradle file:
