Where to call CCDirector::sharedDirector->purgeCachedData? If I call at every screen transition screen transition; won’t be smooth. If I occasionally with in few screen transition game hangs. I am not doing app will crash. In IOS I can easily do it by*applicationdidirecievedmemorywarning_ But how can do it same in android, is doing it in*applicationwillgobackground_ fine? What is the usual/tested way of texture memory releasing in android?
