Blackberry unity game not loading up

I just ported my unity android app to run on blackberry. I am able to install it on the device(simulator) successfully. But when i try to open it up its not opening. I have no idea what the issue is.

Is there anything that i am missing that is specific to blackberry development?Also whats the best way to debug a blackberry device so that i can understand whats happening?Is there something available similar to logcat?

Blackberry bar files generated in unity sometines wont work on specific blackberry OS versions. Maybe try to build the file with previous version of unity?
