活动泄漏了最初添加的窗口

这个错误是什么，为什么会发生?

不仅尝试显示警报，而且当您完成一个特定的活动实例并尝试启动新的活动/服务或尝试停止它时，还可以调用它。

例子:

OldActivity instance;

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

其他回答

在活动销毁前解散progressBar

@Override
    protected void onDestroy() {
        try {
            if (progressDialog != null)
                progressDialog.dismiss();
        } catch (Exception e) {
            e.printStackTrace();
        }
        super.onDestroy();
    }

我在我的视频播放器应用程序中获取了这些日志。这些消息是在视频播放器关闭时抛出的。有趣的是，我曾经以随机的方式在几次运行中获得这些日志。此外，我的应用程序不涉及任何progressdialog。最后，我用下面的实现解决了这个问题。

@Override
protected void onPause()
{
    Log.v("MediaVideo", "onPause");
    super.onPause();
    this.mVideoView.pause();
    this.mVideoView.setVisibility(View.GONE);
}

@Override
protected void onDestroy()
{
    Log.v("MediaVideo", "onDestroy");
    super.onDestroy();
}

@Override
protected void onResume()
{
    Log.v("MediaVideo", "onResume");
    super.onResume();
    this.mVideoView.resume();
}

覆盖OnPause调用mVideoView.pause()和设置可见性为GONE。通过这种方式，我可以解决“活动已泄漏窗口”日志错误问题。

在我的例子中，原因是我忘记在Android manifest文件中包含权限。

我是怎么知道的?好吧，就像@Bobby在接受的答案下面的评论中所说的那样，只要进一步向上滚动到日志，就会看到真正抛出异常的第一个原因或事件。显然，消息“活动已经泄漏了最初添加的窗口”只是一个异常，无论第一个异常是什么。

窗口泄漏异常有两个原因:

1)当Activity上下文不存在时显示对话框，为了解决这个问题，你应该只显示你确定Activity存在的对话框:

if(getActivity()!= null && !getActivity().isFinishing()){
        Dialog.show();
}

2)对话框不适当解散，解决使用以下代码:

@Override
public void onDestroy(){
    super.onDestroy();
    if ( Dialog!=null && Dialog.isShowing() ){
        Dialog.dismiss();
}
}

只需确保您的活动不会由于代码中某处引发的异常而意外关闭。通常在异步任务中，当activity在doinBackground方法中面临强制关闭时，asynctask返回到onPostexecute方法。
