I developed a Android-Homescreen-Widget and got a weird problem: The "Open"-Button in the Market grayed out because there is actually no Application to launch. So, many people complain because they don't realize that my package is a widget. They even give me a bad rating and I want to avoid that by giving the people a hint what they should do. A first-line-hint in the description (written in Uppercase) didn't help at all, so I'm searching for a better solution.
Is it possible to display a message directly after the installation of a package in the android-market?
