Previously I tried exporting to Phonegap and I hit the same white screen error as some guys here encountered. I tried changing the index.html file to something like below and it works on my samsung tab 10. On my samsung tab 7 it seems to be cut off, and on my htc phone it just went screwy. From my testing, I deduced that the cause of it is the javascript code that resizes the canvas through jquery is bugged. I modified the resize code and currently the resizing works so far, although I need to do a lot more test...
index.html code below, replace your with this one and recompile your apk.
