当前回答

我在AlertDialog上错误地调用hide()而不是dismiss()触发了这个错误。

其他回答

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。

唯一的答案是

  @Override
    public void onBackPressed() {

        exit_popup();
       // super.onBackPressed(); remove this line

    }

最好的解决方案是把它放在显示progressbar或progressDialog之前

if (getApplicationContext().getWindow().getDecorView().isShown()) {

  //Show Your Progress Dialog

}

当您退出活动后试图显示对话框时，会出现此问题。

我只是通过写下下面的代码解决了这个问题:

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

基本上，从哪个类你开始progressDialog，覆盖onDestroy方法，这样做。它解决了“活动已泄漏窗口”的问题。
