using NotificationManager into an android service

Question

I have a service running in the background and I want to notify user if there is a new data, I've used a notificationmanager, and the notification appears, but when clicking on it it doesn't do anything (it is supposed to show an activity I'm new in android and here is my code

NotificationManager notificationmanager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notification = newNotification(R.drawable.shoppingcarticon, "Nouvelle notification de ShopAlert", System.currentTimeMillis());
notification.defaults |= Notification.DEFAULT_VIBRATE;
notification.flags |= Notification.FLAG_AUTO_CANCEL;

Intent intent = new Intent(this,GooglemapActivity.class);
PendingIntent activity = PendingIntent.getService(this, 0, intent, 0);

notification.setLatestEventInfo(this, "This is the title", "This is the text", activity);
notification.number += 1;
notificationmanager.notify(0, notification);

your help will be appreciated.

Answer 1

You can use this code. Change Main.Class to your activity class, And Title and content text as you need them.

String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);


int icon = R.drawable.ic_action_search;
CharSequence tickerText = "Pet Parrot";
long when = System.currentTimeMillis();

Notification notification = new Notification(icon, tickerText, when);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
Context context = getApplicationContext();
CharSequence contentTitle = "Hungry!";
CharSequence contentText = "your parrot food meter is: ";
Intent notificationIntent = new Intent(context, Main.class);
PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0);

notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

mNotificationManager.notify(1, notification); // Log.d("test", "Saving Data to File from Service.");

Answer 2

The following line:

PendingIntent activity = PendingIntent.getService(this, 0, intent, 0);

should look this way:

PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);

since you're trying to start an Activity, not a Service. Hope this helps.
