I used at AppDelegate's deconstructor a log, and it was not printed.
I was looking and I found that AppDelegate object is created on the heap and probably it is not released.
Please look on the Android's main.cpp:
void cocos_android_app_init (JNIEnv* env) {
LOGD("cocos_android_app_init");
AppDelegate *pAppDelegate = new AppDelegate();
}
Does it should be like this?
