What is this leaked window?

你的情况WindowLeaked exception正在发生的事情，因为你没有完成活动之前驳回MyProgressDialog。因此它泄漏了与之相关的内存。

一般情况下：

的WindowLeaked exception当你有某种形式的异步任务是在这个开始它的活动结束后，一般情况，在案件发生destroyed.This型异常的主要表现为Dialogs，在活动上下文被销毁之前，我们没有关闭对话框。

所以这是为了更好地显示该对话框之前把一张支票，如下：

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

解决方案针对上述问题是dismiss的MyProgressDialog之前完成的活动。

修改代码如下：

protected void onPostExecute(String file_url) { 

    // your first line should be this 

    if (MyProgressDialog!=null && MyProgressDialog.isShowing()){ 
     MyProgressDialog.dismiss(); 
    } 

    // rest of the code 
}

有问题与警告对话框地方。您不是在任何地方解除您启动的对话框，也不会拨打.dismiss()。此外，仅供参考，您不需要onPostExecute中的runOnUiThread，因为此函数在UI线程本身中运行。

在退出您的活动之前您创建的对话框上呼叫解除（），例如，在的onPause（）
