当前回答

窗口泄漏异常有两个原因:

1)当Activity上下文不存在时显示对话框，为了解决这个问题，你应该只显示你确定Activity存在的对话框:

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

2)对话框不适当解散，解决使用以下代码:

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

  if (mActivity != null && !mActivity.isFinishing() && mProgressDialog != null && mProgressDialog.isShowing()) {
        mProgressDialog.dismiss();
    }

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

}

如果你在doInBackground()函数中有一个错误，并且有这样的代码，就会出现这种情况。

最后尝试添加对话。首先检查并修复doInBackground()函数

protected void onPreExecute() {
     super.onPreExecute();
     pDialog = new ProgressDialog(CreateAccount.this);
     pDialog.setMessage("Creating Product..");
     pDialog.setIndeterminate(false);
     pDialog.setCancelable(true);
     pDialog.show();

 }

 protected String doInBackground(String...args) {
     ERROR CAN BE IS HERE
 }

 protected void onPostExecute(String file_url) {
     // dismiss the dialog once done
     pDialog.dismiss();
