how to show animation only once per applicaton run (Android) : I have 2 activities in my app, Activity 1 (with some elements) and Activity 2 which has Progress Bar (and the user needs to move between those all the time), 
i want to show this progress bar in ony th first time the user moves to the activity 2, every time the app launches (meaning if the app was closed and reopened and the user switched to activity 2 i want to show this progress bar again, how can i achieve this?
Thanks!
