how can i create a very simple animated image / progress bar on android device?

i am doing some processing in the background in my app and i am in need to show a small indicator what the app is retrieving data from the server. in a perfect world i would use an animated gif b开发者_JS百科ut since google decided not to support it i need a solution. i don't want the build-in dialog box that prevents the user from using an app. i need to be able place it anywhere on my layout and show/hide it when i need to. my app runs on 2.2+

any help is appreciated :)

Use ProgressBar.
