Hi!
let me first clarify your request.
it has to do with BlackBerry PLAYBOOK, not the Android devices?
It is on the Android that works, but you are experiencing problems with the PlayBook?
What version of PlayBook (OS 1.0 or 2.0), and what development environment are you using?
Second, I work for a company who is partner with RIM (BlackBerry manufacturer), and I was amongst the few who won BlackBerry PlayBook competition award - thus I have developed few PlayBook applications.
I left you a couple other questions in the PMB section, please have a look at those as well.
Looking forward to hear from you,
best
Hrvoje
