Android - When launch the same activity from widget with different extras, how to prevent the same instance show up after returned from HOME button?

Question

I have a widget that contains 4 buttons to show 4 stock prices, each of them will launch into the same activity Quote.class to show stock details. In onUpdate(), it will set

Answer 1

clickIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Since: API Level 1 If set, the new activity is not kept in the history stack. As soon as the user navigates away from it, the activity is finished. This may also be set with the noHistory attribute.

This solved the same issue of mine while implementing widget activities.
