Okay this could be a solution, but unfortunately ddls doesn't work on other platforms, and I want my game to work on iOS and Android. Maybe we can try to use asynchronous fonctions that can manage to communicate with a server in order to store and download informations but I don't know if this way is quick enouth to manage an action multiplayer game or a mass multiplayer online one.
Thanks for the answer. Unfortunately, YYG also mentioned that dll should not be able work on mobile. So I can't use dlls such as 39dll to handle multiplayer. I'm not an expert in mobile network but the best sould be to add the general multiplayer fonctions that we all know under the library "mplay". In fact, It must be impratical to create two different multiplayer engine to port the same game on android and on iOS.
Maybe a software update would fix that issue, the problem is that I encountered the same issue with two different android phones running the rom Froyo (htc desire Z) and gingerbread (htc desire)... As I believe that the greatest part of android users are running the same roms (android 3.x and 4.x arn't spread at all) I don't think that 70% of my game users are to upgrade their rom if they find some graphics bugs. So is there another solution?
