Showing notificaiton, passing parameter from Intent to activity

//my activity is under com.hello

//my activity class name is HelloAndroidActivity

In your IntentService class or Service class do following:

private void showNotification() {

        String ns = Context.NOTIFICATION_SERVICE;

        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

        int icon = R.drawable.icon;

        CharSequence tickerText = "some ticket text";

        long when = System.currentTimeMillis();

        Notification notification = new Notification(icon, tickerText, when);

       

        Context context = getApplicationContext();

        CharSequence contentTitle = "Some title";

        CharSequence contentText = "Some content";

        Intent notificationIntent = new Intent(this, HelloAndroidActivity.class);

       

        notificationIntent.setAction("com.hello"+System.currentTimeMillis());//notice : com.hello

   

        notificationIntent.putExtra("extra0", "some xtra message");

        notificationIntent.putExtra("extra1", "extra message");

       

       

        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_SINGLE_TOP);

        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT | Notification.FLAG_AUTO_CANCEL);

        notification.flags |= Notification.FLAG_AUTO_CANCEL;

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

        mNotificationManager.notify(1, notification);//where 1 is the id,, different id will have different notification

   

    }

   
   
    in your activity class override onNewIntent method as shown below for example

   

    public void onNewIntent(Intent intent) {

        super.onNewIntent(intent);

        Bundle extras = intent.getExtras();

        String extra0 = extras.getString("extra0");

        String extra1 = extras.getString("extra1");

    }
