I have a few questions about theming apps. I don't know much about Android apps, but was thinking about looking into theming some. Before I do, I want to find out if it is worthwhile or if it will be constant re-theming after every update. When an app is themed (like the Revolution Facebook version for example) Can it be updated through the market or released APK? If updated through the market, will it be overwritten when the app updates? Do market updates only change the pieces needed or do they replace the whole app? Are themed apps always complete versions or are they sometimes just the images and other parts that were themed?
