    public GCMIn         


        

Answer 1

public void getnotification(View view) {

       NotificationManager notificationmgr =(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
       Intent intent = new Intent(this,resultpage.class);
       PendingIntent p = PendingIntent.getService(this,(int) System.currentTimeMillis(),intent,0);


       Notification n = null;
       if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
           n = new Builder(this)
                                .setSmallIcon(R.mipmap.ic_launcher)
                               .setContentTitle("Hello android user here")
                               .setContentText("welcome to notification serrvice")
                               .setContentIntent(p)
                               .build();

           notificationmgr.notify(0,n);

       }
