Welcome to this forum
You won't get an answer to your thread (it's more about "how do I create an app" instead of a single problem).
As a new member please take a look to the beginner's guide (there are a lot of examples which will help you):
How to use
- graphics (and other views)
- timers (better: services)
- files
Try to load an image from a file to a view. Check how timers work. After that it will be easy.
Most important: Use the search function.
