Hello and welcome to the forums... thanks for joining!

I do not know what it is you are trying to do... it looks liek a development type of question and, as such, I am unable to help.

If it is development related, you would get a better answer by posting in Android Development - Android Forums (as other devs hang out in there).

Hope you find this place useful... shout out to one of us guides if you need any help navigating the forums
