I created a kind of chess watch and build an apk usign PhoneGap. But i need that the screen never turns black (to save phone battery).
How can I configure my apk so it keeps active and still been showed in the screen all the time, while it's been used?

You don't configure the apk, you must use the device settings. Or there are some apps on the store that allow more detailed override of the screen timeout but you don't do it with the game itself.
