}

Public void onClick (View v) {

Intent Intent=new Intent (this, NotificationActivity. Class);
PendingIntent PI=PendingIntent. GetActivity (this, 0, intent, PendingIntent. FLAG_UPDATE_CURRENT);
NotificationManager manager=(NotificationManager) getSystemService (NOTIFICATION_SERVICE);
NotificationCompat. Builder Builder=new NotificationCompat. Builder (this);
Notification Notification=builder. SetSmallIcon (R.m ipmap. Ic_launcher)
SetContentTitle (" this is the content title ")
SetContentText (" this is the content text ")
SetWhen (System. CurrentTimeMillis ())
