应用程序在重新启动活动时崩溃

我已经看到几个帖子出现这个错误。但是，他们还没有提供解决我的问题的解决方案。应用程序在重新启动活动时崩溃

我有两个活动类，MainActivity和GameActivity。 MainActivity在按下按钮时启动GameActivity。如果我按下手机上的后退按钮，它会回到主要活动。然而，当我再次按下按钮，启动一个新的GameActivity，我提示指向的代码行的错误

setContentView(R.layout.activity_game);

错误：

为MainActivity onCreate方法：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    setContentView(R.layout.activity_main); 
    mainActivity = this; 
    playbtn = (ImageView) findViewById(R.id.imageView); 
    final Intent intent = new Intent(getBaseContext(), GameActivity.class); 
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
    playbtn.setOnTouchListener(new View.OnTouchListener() { 
     @Override 
     public boolean onTouch(View view, MotionEvent motionEvent) { 
      playbtn.setImageResource(R.drawable.playbutton2); 
      startActivity(intent); 
      getIntent().removeExtra("startTest"); 
      return true; 
     } 
    }); 
}

为GameActivity

onCreate方法：

public void onCreate(Bundle savedInstanceState){ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_game); 

    gameView = (GameView)findViewById(R.id.gameView); 
    gameView.setGameActivity(this); 
    gameThread = new Thread(gameView); 
    gameThread.start(); 
    MainActivity.resetButton(); 
}

activity_game XML文件：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    tools:context="joseph.imbroglio.GameActivity" 
    android:layout_width="match_parent"  android:layout_height="match_parent"> 

    <joseph.imbroglio.GameView 
     android:id="@+id/gameView" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" /> 

    <TextView 
     android:text="TextView" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerVertical="true"

     android:id="@+id/textView" 
     android:textSize="24sp" 
     android:textColor="?android:attr/colorBackground" />

public static void resetButton(){ 
    playbtn.setImageResource(R.drawable.playbutton); 
}

请发布'GameView'的代码。 – earthw0rmjim

joseph.imbroglio.GameView ??发布GameView代码 – SaravInfern

您的图片太大。看看使用图像加载库 –

假设你GameActivity开始正确的第一次，但按BACK后（返回MainActivity），然后开始GameActivity崩溃（由于内存不足），可能意味着你是不是完全正确清理时，原GameActivity的实例结束。

从您发布的代码中，您可能有内存泄漏。此代码：

gameView = (GameView)findViewById(R.id.gameView); 
gameView.setGameActivity(this); 
gameThread = new Thread(gameView); 
gameThread.start();

传递一个参考gameView到gameThread。 gameView有一个参考GameActivity的实例。如果在GameActivity实例关闭时没有正确地清除此Thread，则在尝试启动第二个实例之前，垃圾回收器将无法回收旧的GameActivity及其所有资源（包括您的图像）。您可以使用堆分析和堆调试工具来帮助您找到像这样的内存泄漏。

非常感谢，这种见解完全解决了我的问题。如果对别人有帮助，我在GameActivity的onStop方法中创建了一个onStopRequested布尔值设置为true。当线程的run方法看到这个布尔值为真时，它会返回。 – Joseph

我认为您用于该应用的图片大小可能不支持您的手机。尽量减少图像的大小。

也许你是对的，一个常见的问题是当尝试膨胀一个imageview加载可绘制资源时，内存不足异常。如果其中一个资源具有较高的像素分辨率，则会占用大量内存，从而导致膨胀异常。 – El0din

如果GameActivity第一次正确打开，但不是第二次，这个答案是不对的。这些答案如何得到upvotes？想想，人！ –
