Electrum Balance Widget for Android

[john_doe]

Is there any widget for Android that shows you the total balance of your Electrum wallet? I've seen a couple of widgets that allow you to monitor the balance of a given address or set of addresses, but I would simply want to input my master public key instead of the individual addresses. I know the official Android app allows you to see this balance, but I want to see it at all times in the wallpaper.
