GcmManager

This is a helper singleton for the Google Cloud Messages API. Based on Google Play Services 4 for Android.

The code for device registration is taken from the Google Developer Guide "Implementing GCM Client".

Usage

Simply initialize GcmManager in any class (e.g. your application class). Set the FeedbackListener to perform callback

import main.java.com.dreebit.gcm.GcmFeedbackListener;
import main.java.com.dreebit.gcm.GcmManager;

public class YourApplication extends Application implements GcmFeedbackListener{

	private NotificationManager mNotificationManager;
    NotificationCompat.Builder builder;

    @Override
    public void onCreate() {

        super.onCreate();
        GcmManager.initialize(getApplicationContext(), "YOUR_SENDER_ID", this);

    }

	@Override
    public void onRecoverableError(int resultCode) {

        Toast.makeText(getApplicationContext(), GooglePlayServicesUtil.getErrorString(resultCode), Toast.LENGTH_SHORT).show();

    }

    @Override
    public void onDeviceWillRegister() {
    	// Do some stuff before registration
    }

    @Override
    public void onDeviceDidRegister(String result) {
    	// Do some stuff after registration
    }

    @Override
    public void onDeviceRegistered(String regId) {

        Log.v(TAG, "Device registered: " +regId);

    }

    @Override
    public void onReceiveMessage(String message) {

        mNotificationManager = (NotificationManager)
                this.getSystemService(Context.NOTIFICATION_SERVICE);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
                new Intent(this, DashboardActivity.class), 0);

        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                        .setSmallIcon(R.drawable.vsm_logo)
                        .setContentTitle("Notification")
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText(message))
                        .setContentText(message);

        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(1, mBuilder.build());

    }
}
