I am new to push notifications in android so i followed the following tutorial on android developer page.
http://developer.android.com/google/gcm/client.html
The thing i am not clear is in the intentservice class.It is shown below:
import com.google.android.gms.gcm.GoogleCloudMessaging; import com.igloo.fragments.sportsfragment; import android.app.IntentService; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.support.v4.app.NotificationCompat; import android.util.Log; public class GcmIntentService extends IntentService { public static final int NOTIFICATION_ID = 1; private NotificationManager mNotificationManager; NotificationCompat.Builder builder; public GcmIntentService() { super("GcmIntentService"); } @Override protected void onHandleIntent(Intent intent) { Bundle extras = intent.getExtras(); GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this); // The getMessageType() intent parameter must be the intent you received // in your BroadcastReceiver. String messageType = gcm.getMessageType(intent); if (!extras.isEmpty()) { // has effect of unparcelling Bundle /* * Filter messages based on message type. Since it is likely that GCM * will be extended in the future with new message types, just ignore * any message types you're not interested in, or that you don't * recognize. */ 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()); // If it's a regular GCM message, do some work. } else if (GoogleCloudMessaging. MESSAGE_TYPE_MESSAGE.equals(messageType)) { //Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime()); // Post notification of received message. sendNotification("Received: " + extras.toString()); //Log.i(TAG, "Received: " + extras.toString()); } } // Release the wake lock provided by the WakefulBroadcastReceiver. GcmBroadcastReceiver.completeWakefulIntent(intent); } // Put the message into a notification and post it. // This is just one simple example of what you might choose to do with // a GCM message. private void sendNotification(String msg) { mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, sportsfragment.class), 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_launcher) .setContentTitle("GCM Notification") .setStyle(new NotificationCompat.BigTextStyle() .bigText(msg)) .setContentText(msg); mBuilder.setContentIntent(contentIntent); mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build()); } } The thing that confuses me is the final method:
private void sendNotification(String msg) { mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, DemoActivity.class), 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_stat_gcm) .setContentTitle("GCM Notification") .setStyle(new NotificationCompat.BigTextStyle() .bigText(msg)) .setContentText(msg); mBuilder.setContentIntent(contentIntent); mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build()); Can someone please clarify why the pending intent is used here to DemoActivity.class.And also explain what this line does: mBuilder.setContentIntent(contentIntent);
My understanding is that it takes you to the class where you want to go when i click on the notifciation from the notification bar above.Is it right? }
