I want to use a texture atlas of 2048 x 2048 in my game, and I would like to warn the users with a "too low" device to not download the game.

With a texture atlas of this size, what requirements should I say, on ANDROID ?

This image (source : http://stackoverflow.com/questions/10392027/recommended-limit-for-memory-management-in-cocos2d ) shows the requirements for IPHONE, what about for ANDROID : 512Mo minimum, with a 1GHz, is a correct requirement ?

Thanks for your answer
