How to restart / refresh contents of activity on notification click

Question

I am trying to refresh the contents of an activity on click of a notification. I can navigate to the activity when I am in some other activity and I click on the notification. What I am trying to achieve is, I am in Activity A which is displaying some content. I get a new notification, I click on it Activity A should either be relaunched or the content in the activity should be refreshed with respect to what I am passing in the PendingIntent of the Notification.

What all I have done,

1. Tried setting PendingIntent.FLAG_CANCEL_CURRENT and PendingIntent.FLAG_UPDATE_CURRENT

2. Tried setting Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP in the intent I am passing along with the pending intent.

3. Checked the data in onNewIntent() its doesn't get refreshed. I get the same data which I have passed in the old intent.

4. Passed a unique requestCode along with the PendingIntent as well, still the same.

Any Other suggestions?

If you use Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP, this should recreate the activity if it was in the stack, or start a new activity if it wasn't in the stack. If you don't want the activity to be recreated (if it is already in the stack), you can use Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP.
