To be honest, this looks a lot like an iPhone button which would look ugly in Android. Especially in combination with default textboxes, switches, etc.<p>Android apps should a) use the default style b) use default style mixed with moderately customized default elements (different color etc.) c) use custom elements for everything using a style that doesn't look ugly on Android (ie no iPhone-like shiny buttons).
When I saw your iOS demo last week, I considered creating an Android port. Thankfully, I didn't have the time, and your implementation is fantastic for a 0.1.0. Great job!
