Android wallpaper application

Need an Android application to be published in the Android Market. It should do the following: - User should be able to select from 5 pre-defined pictures or photos that come with the app. - User should be able to select how many of the 5 photos should change in background in a selected time interval. - User should be able to define if the photo will rotate depending on the orientation of the phone or tablet (rotation on/off). - Very simple UI: 5 check boxes for photos, 1 for rotation, and time interval input in minutes if 2 or more photos are selected. - Pictures should re-size automatically depending on the screen size and orientation of the phone or tablet. - Support OS 2.1 and above.
