Android应用程序在第二次启动时冻结

Question

我正在开发一款针对android的游戏，并且我一直试图实现一个对话框来显示web横幅广告的webview。 （我使用cocos2d开发）。我使用静态方法ads（）静态地打开对话框。但是，由于这样做，我开始遇到问题。

第一次启动时，它运行良好，但当应用程序关闭并重新打开时，“openscreen”场景开始，但不会播放淡入和淡出，或继续进入菜单场景。

活动（其中广告（）方法）

Openscreen-上推出使用的第一个场景

package wingdev.defence; 

import org.cocos2d.actions.instant.CCCallFunc;

CCSprite wingdev = CCSprite.sprite("wingdevpresents.png"); 
CCSprite darkorange = CCSprite.sprite("PirateTea.png");

public static CCScene scene() 
{ 
    // 
    CCScene scene = CCScene.node(); 
    CCColorLayer layer = new OpenScreen(ccColor4B.ccc4(255, 255, 255, 255)); 
    scene.addChild(layer); 

    return scene; 
} 
protected OpenScreen(ccColor4B color) { 
super(color); 
CGSize winSize = CCDirector.sharedDirector().displaySize(); 
this.setIsTouchEnabled(true); 
back2.setPosition(winSize.width/2.0f, winSize.height/2.0f); 
back2.setScaleX(winSize.width/back2.getContentSize().width); 
back2.setScaleY(winSize.height/back2.getContentSize().height); 
addChild(back2); 
wingdev.setPosition(winSize.width/2.0f, winSize.height/2.0f); 
wingdev.setScaleX(winSize.width/wingdev.getContentSize().width); 
wingdev.setScaleY(winSize.height/wingdev.getContentSize().height); 
addChild(wingdev); 
wingdev.runAction(CCSequence.actions(CCFadeIn.action(1.0f),CCDelayTime.action(2.0f),CCFadeOut.action(1.0f), CCCallFunc.action(this,"openscreen2"))); 
} 
public void openscreen() 
{ 
    CCDirector.sharedDirector().replaceScene(Menu.scene()); 
} 
public void openscreen2(){ 
    CGSize winSize = CCDirector.sharedDirector().displaySize(); 
    removeChild(wingdev,true); 
    darkorange.setPosition(winSize.width/2.0f, winSize.height/2.0f); 
    darkorange.setScaleX(winSize.width/darkorange.getContentSize().width); 
    darkorange.setScaleY(winSize.height/darkorange.getContentSize().height); 
    addChild(darkorange); 
     darkorange.runAction(CCSequence.actions(CCFadeIn.action(1.0f),CCDelayTime.action(2.0f),CCFadeOut.action(1.0f),CCCallFunc.action(this,"openscreen"))); 
} 
} 

理解任何帮助，我要去哪里错了将是非常赞赏！

Answer 1

，您暂停CCDirector在

@Override 
public void onPause() 
{ 
    super.onPause(); 
    CCDirector.sharedDirector().pause(); 
} 

我认为你需要在的onResume再次启动它（）

@Override 
public void onResume() 
{ 
    super.onResume(); 
    CCDirector.sharedDirector().resume(); 
} 

在onStart（）将不会被调用，如果应用程序没有杀害。
