Question

我收到以下错误消息：

"Activity has leaked window com.android.internal.policy.impl.PhoneWindow$DecorView@417521e0 that was originally added here..."

我检查了其他stackoverflow线程，但它们都处理附加了Dialogs的活动。我没有，我只使用我的PreloadActivity来显示一个静态（通过黑色）屏幕，同时启动另一个Activity（它有一个黑色的淡入，所以这没关系）。我的代码如下：

@Override
protected void onCreate(Bundle savedInstanceState) {
    Log.d("myapp", "PreloadActivity.onCreate");
    super.onCreate(savedInstanceState);

    // Set full screen mode and disable the keyguard (lockscreen)
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN  
                         | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD 
                         | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                         | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    setContentView(R.layout.preload);
}

@Override
protected void onStart() {
    Log.d("myapp", "PreloadActivity.onStart");
    super.onStart();
}

@Override
protected void onResume() {
    Log.d("myapp", "PreloadActivity.onResume");
    super.onResume();

    Intent intent = new Intent(this, MyMainActivity.class);
    startActivity(intent);
    overridePendingTransition(0, 0); // no animation
    finish(); 
}

这里有什么'泄露'？这有关系吗？

UPDATE ：相关的logcat部分（包括堆栈跟踪）。该设备是HTC One V。

Answer 1

当你完成一个特定的活动实例并尝试启动一个新的活动，服务或使用该实例停止它时，就会发生这种错误，例如...

OldActivity instance;

oncreate()
{
   instance=this;
}

method() {
instance.finish();
instance.startActivity(new Intent(ACTION_MAIN).setClass(instance, NewActivity.class));
}

活动已泄露最初添加的窗口（未附加对话框）
