У меня есть следующий код.Android HttpClient Два разных httpposts не работают?
- Я хочу публиковать сообщения в первый раз, когда пользователь нажимает кнопку, что данные будут отправляться на адрес httpclient и будут возвращать данные. Это прекрасно работает (кнопка 1). Когда пользователь нажимает кнопку 1, он дает правильные результаты.
- Затем я хочу отправить второй раз с различными данными в httpclient. Когда пользователь нажимает кнопку 2. Данные будут отправляться функции, но журналы (см. Код) возвращаются в исключения каждый раз, когда NULL. Поэтому я думаю, что он не отправит httpclient и не заполнит httppost данными, которые я хочу отправить.
Мой вопрос: что я не так, или я забыл?
- Нужно ли мне создать второй обработчик httpclient?
- Нужно ли создать второй обработчик httppost?
Просьба помочь.
спасибо.
