What is this leaked window?

您的WindowLeaked exception情况正在发生，因为您MyProgressDialog在完成活动之前没有解雇。因此，它正在泄漏与之关联的内存。

一般情况：

当WindowLeaked exception您有某种异步任务在启动它的活动被销毁后完成时，通常会发生这种情况。这种类型的异常主要发生在Dialogs我们没有在活动上下文被销毁之前关闭对话框的情况下。

所以最好在显示对话框之前打勾，如下：

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

上述问题的解决方案dismiss是在MyProgressDialog完成活动之前。

修改您的代码如下：

protected void onPostExecute(String file_url) {

    // your first line should be this 

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

    // rest of the code 
}

某处的警报对话框存在问题。您不会在任何地方关闭您发起的对话，也不会调用.dismiss(). 同样仅供参考，您不需要runOnUiThread在内部onPostExecute，因为此函数在 UI 线程本身中运行。

在退出 Activity 之前，在您创建的 Dialog 上调用dismiss()，例如在 onPause()
