I am glad to present you a little project we started few days ago :
Basically it is a centralized place where any Android Market applications can have their bugtool.
Spontaneously users can log bugs there and the developer will get notified.
Android developers of their respective application can "take ownership" on the site and have a free bugtool.
It uses google oauth so it is really easy to use, no sign in nor password required.
Feel free to send us some feedback !
NB: We are currently testing an API to integrate your applications directly with the tool, feel free to ask the access if you want to beta test it !
