Question

我正在使用cocos2dx v3.9和ndk 10e与android 4.4.2。我创建了一个图层，并且该按钮存在。按下按钮时，将从父项中删除图层并执行清理并执行其他任务。按下按钮时出现崩溃，大部分是在按钮出现时轻敲。点击按钮上的代码是： -

CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("tap.wav");
  unschedule(schedule_selector(InstructionLayer::callNextButtonMethod));

  if (this->delegate != NULL) {
    delegate->clickNextButton();
  } else {
    CCLOG("Delegate null");
  }      
  this->removeFromParentAndCleanup(true);
}

我的ndk崩溃转储是： -
