我正在尝试在我的 Adroid 应用程序中使用带有异步任务的进度对话框。但是当我运行我的应用程序时，这会导致致命异常。当我以另一种方法使用它时，它可以正常工作。但是当我用下面的方法使用它时，它导致了一个错误。我在其他问题中读到这是因为数组，但我不知道这是否属实。
这是我的活动代码：
private class TheTask extends AsyncTask<Void, Void, Void>{
@Override
protected void onPreExecute() {
authProgressDialog = ProgressDialog.show(Front9Activity.this, "", "Authenticating...", true, false);
}
@Override
protected Void doInBackground(Void... params) {
loading();
return null;
}
@Override
protected void onPostExecute(Void result) {
if(authProgressDialog.isShowing()) {
authProgressDialog.dismiss();
}
return;
}
}
public void loading(){
