phonegap, sencha in android

Question

I have an application which is almost getting finished off now. Now there is a last module which has got a listview in it. I was worndering if I could use sencha + phonegap + android in only that activity of mine. Is it possible? And also, with the tutorial in phonegap android, it was not clear as to where should I edit my androidmanyfest file. Can someone please explain that.

cheers
