当视图无法找到启动或初始化它的上下文时，通常会出现泄漏窗口错误。

在开始新活动之前先关闭进度对话框。就像当您的前一个活动对话框没有找到相同的上下文时您的新活动开始时一样。因此，在 onpause 方法或 on destroy 方法中编写您的对话框关闭代码。

在这里，您正在 doinbackground 方法中启动活动并在 postexecute 中完成对话框，这会导致泄漏窗口错误。

尝试这个 ：

@Override
        protected void onPostExecute(String file_url) {
            // dismiss the dialog once product deleted
             if(success==1){     
                      if (progressDialog != null) {
                          if (progressDialog.isShowing()) {
                                 progressDialog.dismiss();
                          }
                            //Start your activity here . . . .  

                          }
                     }
                if (file_url != null) {
                Toast.makeText(ActivityOwner.this, file_url, Toast.LENGTH_LONG).show();
            }

        }

您将在关闭对话框之前完成活动。试试这个。

@Override
protected void onDestroy() {
   if (progressDialog != null) {
      if (progressDialog.isShowing()) {
          progressDialog.dismiss();
      }
   }
  super.onDestroy();
}

在开始新活动之前，您正在 doInBackground 中开始新的意图，您需要取消 ProgressDialog

我更喜欢这个代码来关闭 ProgressDialog。pd 是下面代码中的 ProgressDialog

    @Override
public void startActivity(Intent intent) {
    if(pd!=null && pd.isShowing()){
        pd.dismiss();
    }
    super.startActivity(intent);
}
