I have attempted to port my app (https://play.google.com/store/apps/details?id=com.sjwindsurf...) using eclipse back when the Playbook had just come out, RIM were offering a Playbook to anyone who submitted an application to App World. I was very busy at the time, but attempted to port my app across (WindFreak), as it was supposed to be quick and painless. It basically didn't work at all.

It would get to the loading stage in the virtual Playbook, and crash every time, no real way of debugging it (not that I could find). It might have been due to the complexity of my app, and at the time there was no list of compatible functionality. I gave up after wasting 1 day on this. It might be easier to accomplish now.
