当前回答

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。

其他回答

我也有同样的问题。错误不在对话框中，而是在编辑文本中。我试图改变一个异步任务内的编辑文本的值。我唯一能解决的问题就是创造一个新的可运行对象。

runOnUiThread(new Runnable(){
      @Override
      public void run() {
       ...        
      }
    });

其他隐藏你的对话框，将其解散。

用.dismiss()替换.hide()

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();
    }

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。

当我在AsyncTask中使用ProgressDialog时，这种情况发生在我身上。实际上，我在onPostExecute中使用hide()方法。基于@Alex Volovoy的答案，我需要使用遣散()与ProgressDialog删除它在onPostExecute和它完成。

progressDialog.hide(); // Don't use it, it gives error

progressDialog.dismiss(); // Use it
