泄漏了最初在此处添加的窗口

Question

这是我的代码

class BuatPeminjaman extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(DetailsActivity.this);
pDialog.setMessage("Booking...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
@Override
protected String doInBackground(String... arg) {
int success;
try {
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("gedung", gedung));
params.add(new BasicNameValuePair("lantai", lantai));
params.add(new BasicNameValuePair("nim", nim));
params.add(new BasicNameValuePair("nama", nama));
params.add(new BasicNameValuePair("jumlah peserta", peserta));
params.add(new BasicNameValuePair("keperluan", keperluan));
params.add(new BasicNameValuePair("ruang", ruang));
Log.d("request!", "starting");
JSONObject json = jsonParser.makeHttpRequest(LOGIN_URL, "GET", params);
// checking log for json response
Log.d("proses membuat", json.toString());
// success tag for json
success = json.getInt(TAG_SUCCESS);
if (success == 1) {
Log.d("Berhasil membuat !", json.toString());
return json.getString(TAG_MESSAGE);
} else {
return json.getString(TAG_MESSAGE);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(String message) {
pDialog.dismiss();
Toast.makeText(DetailsActivity.this, "Berhasil meminjam kelas", Toast.LENGTH_SHORT).show();
Intent i = new Intent(DetailsActivity.this, MainActivity.class);
startActivity(i);
}
}

我不知道错误是什么意思。我已经在我的对话框中调用了关闭，但它仍然不起作用。它显示对话框，但之后强制关闭。我有错误是因为我尝试发布的 JSON 还是什么？

这是我的日志猫

请帮忙。或者，如果您有任何建议如何将数据发布到数据库而不会出错，那没关系

使用自定义对话框时，请确保布局的高度不会太长。

您正在尝试在退出活动后显示对话框。
