Android - Download manager

I need a download manager for my app, it must: - Contain two lists [ "Upgrades", "Downloads" ] A. Switching between the lists uses a segmented control at the top of the screen B. See: [login to view URL] - Download and display a list of available downloads A. The downloaded list contains [ title, subtitle, url ] B. Each entry is displayed to the user as title in black, subtitle below in grey and smaller text (as iPhone ) - Choosing an item initiates a download of a zip file A. Switch to the "Downloads" list B. Display the title and a progress bar below it for the download C. If the download is broken tapping the item in this list will resume the download - When the download is complete unzip the file onto the sd card
