I am trying to get a simple notification. I've seen lots of examples using old API methods, but i want to use the newer method. I have put this code together from the API resource, and it runs without error. However, i am not seeing any notifications. I have the minimum required to view a notification, at least, i believe so from what i have read. Here is my code :

public class Login extends Activity { public static Context ctx; public void onCreate(Bundle savedInstanceState) { ctx = this; } private static void notice(String msgfrom, String msg) { NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(ctx); mBuilder.setSmallIcon(R.drawable.ic_launcher); mBuilder.setContentTitle("New message from " + msgfrom.toString()); mBuilder.setContentText(msg); mBuilder.build(); } }

THANKS TO HELP BELOW, I MODIFIED MY CODE TO THIS

NotificationCompat.Builder nb = new NotificationCompat.Builder(ctx); nb.setSmallIcon(R.drawable.ic_launcher); nb.setContentTitle("New message from " + msgfrom.toString()); nb.setContentText(msg); nb.setAutoCancel(true); Notification notification = nb.build(); NotificationManager NM = (NotificationManager) ctx.getSystemService(NOTIFICATION_SERVICE); NM.notify(0, notification);

If you want to run Notification in All Android device <= android 4.2 then just add android-support-v4.jar file in you Project and

use below code:

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.notification_icon) .setContentTitle("My notification") .setContentText("Hello World!"); // Creates an explicit intent for an Activity in your app Intent resultIntent = new Intent(this, ResultActivity.class); // The stack builder object will contain an artificial back stack for the // started Activity. // This ensures that navigating backward from the Activity leads out of // your application to the Home screen. TaskStackBuilder stackBuilder = TaskStackBuilder.create(this); // Adds the back stack for the Intent (but not the Intent itself) stackBuilder.addParentStack(ResultActivity.class); // Adds the Intent that starts the Activity to the top of the stack stackBuilder.addNextIntent(resultIntent); PendingIntent resultPendingIntent = stackBuilder.getPendingIntent( 0, PendingIntent.FLAG_UPDATE_CURRENT ); mBuilder.setContentIntent(resultPendingIntent); NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); // mId allows you to update the notification later on. mNotificationManager.notify(mId, mBuilder.build());

this code is work in android 2.1 to 4.2.

Most excellent.. Thank you... I shorted down my code for my situation, but it was your code that got me there!

You are missing the last step. You are building your notification, and you still need to post it to the system, in the following manner :

( (NotificationManager) ctx.getSystemService ( Context.NOTIFICATION_SERVICE ) ).notify ( 100 , mBuilder.build () );

EDIT :

The integer 100 (that I chose randomly) used in the notify method is a unique identifier for the notification. You should use the same identifier if you ever need to update or cancel your notification.

NOTE :

You might have a memory leak by storing your activity's contact in a static variable ! Instead of that, you can change this :

private static void notice(String msgfrom, String msg)

to this

private static void notice(Context ctx , String msgfrom, String msg)

and hence delete the static variable.

Thanks, yea, i derived that from 'Dhaval Sodha Parmar' response. It's a learning curve...
As for you suggestion to not storing my activity in a static variable. Good suggestion - I will try that.

Try this

Just call inside your onCreate()

 Public void Player_Notification() { final String myBlog = "http://android-er.blogspot.com/"; notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); myNotification = new Notification(R.drawable.ic_launcher,"Audio Track is playing in background!",System.currentTimeMillis()); Context context = getApplicationContext(); // here is title String notificationTitle = Title; // here is sub title String notificationText = data; // write your activity name which you want to open when user click on notification Intent myIntent = new Intent(this, Activty.class); PendingIntent pendingIntent = PendingIntent.getActivity(Activty.this, 0, myIntent, Intent.FLAG_ACTIVITY_NEW_TASK); // intent will call your activity as you want myNotification.defaults |= Notification.DEFAULT_SOUND; myNotification.flags |= Notification.FLAG_AUTO_CANCEL; myNotification.setLatestEventInfo(context, notificationTitle, notificationText, pendingIntent); notificationManager.notify(MY_NOTIFICATION_ID, myNotification); }
