There is a huge usability problem on android devices with given focus to text fields. This triggers the keyboard to come up and is especially annoying in poker if you want to place a bet.

Speaking of betting no one needs there a text field because you won't enter a bet amount by keyboard ever. The slider with the buttons for help pot and pot are enough.

Regarding poker please take a look at quarterpoker.com ... they use Cubeia software which has an excellent usability for all platforms. I suggest to just copy that to correct your usability problems.
