Android Reminder Notification

Question

Fairly new to java/android but getting better slowly. I am trying to create a one time notification to remind the user about the app 24 hours after first run. I researched online and using stackoverflow, I was finally able to get the code to run with the following notification code:

private void  addNotification() {
    NotificationCompat.Builder builder =
         new NotificationCompat.Builder(this)
         .setSmallIcon(R.drawable.ic_launcher)
         .setContentTitle("Notifications Example")
         .setContentText("This is a test notification");

    Intent notificationIntent = new Intent(this, MainActivity.class);
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 
                     PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);

    // Add as notification
    NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(1, builder.build());
}

I am trying to call the notification function but it is not working. I am calling it as follows:

addNotification();

How do I proceed from here? I have not dealt with the 24 hr issue, just trying to get the notification to come up. Then upon clicking it, the app should start again.

Try this :

You need to pass two parameters to addNotification(Context context, String Message).

Like addNotification(this,"My Notification");

private void addNotification(Context context, String message) {

  int icon = R.drawable.ic_launcher;
  long when = System.currentTimeMillis();
  String appname = context.getResources().getString(R.string.app_name);
  NotificationManager notificationManager = (NotificationManager) context
   .getSystemService(Context.NOTIFICATION_SERVICE);

  Notification notification;
  PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
  new Intent(context, myactivity.class), 0);


  NotificationCompat.Builder builder = new NotificationCompat.Builder(
  context);
  notification = builder.setContentIntent(contentIntent)
 .setSmallIcon(icon).setTicker(appname).setWhen(0)
 .setAutoCancel(true).setContentTitle(appname)
 .setContentText(message).build();

  notificationManager.notify(0 , notification);

  }

For reminder you can implement AlarmManager or Timer.

Alarm Manager : Android Alarm Manager
Timer : Android Timer

Thanks. I copied and pasted your code. When I added addNotification(this,"My Notification"); I got an error : duplicate method. ideas? – user3593666 May 22 '14 at 11:02
You need to remove your code for "addNotification" and add my code. – Siddharth_Vyas May 22 '14 at 13:14
I removed my code. and added yours. What I have is your code and calling it using addNotification(this,"My Notification"); – user3593666 May 22 '14 at 13:19
I can't run it since there is an error so nothing new in Logcat. – user3593666 May 22 '14 at 13:26
not sure how to proceed. Thanks for your patience. – user3593666 May 22 '14 at 13:27
Check my answer..I have added the example links..Hope this helps – Siddharth_Vyas May 22 '14 at 13:29
I notice the "long when" is never used. Can you help me to use it to set the notification to be 24 hours from the time the app is run. Thanks. – user3593666 May 22 '14 at 15:48
You can implement AlarmManager for that. – Siddharth_Vyas May 23 '14 at 03:48
