之前有个帖子说是 JNIEXPORT void JNICALL Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeOnPause() {
if (CCDirector::sharedDirector()->getOpenGLView()) {
CCApplication::sharedApplication()->applicationDidEnterBackground();
CCLOGINFO("addgetOpenGLViewnullpinter ");
CCNotificationCenter::sharedNotificationCenter()->postNotification(EVENT_COME_TO_BACKGROUND, NULL);
}
}

JNIEXPORT void JNICALL Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeOnResume() {
    if (CCDirector::sharedDirector()->getOpenGLView()) {
        CCApplication::sharedApplication()->applicationWillEnterForeground();
    }
}

Java_org_cocos2dx_lib_Cocos2dxRenderer_nativeOnPause() {
if (CCDirector::sharedDirector()->getOpenGLView()) {--------加这行判断，防止空指针出现，但是加了之后任然会有闪退。 有没有谁遇到过。。。。

http://www.cocoachina.com/bbs/read.php?tid-234889.html 这个贴 是同样的问题 但是贴主没说清楚最后是怎么解决的

#3

你看看是不是用了 通知中心，然后没有 REMOVE掉。我之前因为这个问题 切后台闪退，也是偶尔出现。

#4

我的是在CCRenderTexture::CCRenderTexture()的构造方法中添加了个观察者观察 EVENT_COME_TO_BACKGROUND事件，并绑定了个触发方法CCRenderTexture::listenToBackground（）这个方法什么没有做；然后在CCRenderTexture::~CCRenderTexture()析构里移除了这个个观察者。 请问您说的要remove是指？

#5

就是在 析构函数里 移除这个 观察。你已经移除了 那就不是这个原因。
