I produce the game by using the version of cocos2d-2.1rc0-x-2.1.3.
Phenomenon that screen comes out black when I was working on Android has occurred.
When the game is started, the menu screen will be output properly.
In jni in order to take advantage of facebook menu, the in-app-billing
I will call the activity.
After the call, facebook, in-app-billing screen is displayed correctly.
Exit activity facebook, to in-app-billing available,
When you return to the menu screen of the game, the menu screen is displayed in black.
On the screen that is black, and when I pressed to guess the position of the button,
A new screen will be displayed correctly.
Only when using the activity by using jni, but it looks black,
Why not? Can you how to fix?
