После нескольких часов, пытаясь найти способы, я хотел бы спросить, как я могу правильно отправлять данные с PHP на приложение Android через JSON?Как правильно отправлять данные с php на android через json?
В моем приложении у меня есть собственное диалоговое окно, в котором я ввожу адрес электронной почты. Это будет отправлено через JSONParser.makeHttpRequest в php-файл. -> Это работает! Когда я пытаюсь отправить ответ обратно на мой андроид приложения он дает мне следующую ошибку:
Logcat:
09-26 13:12:02.777: E/JSON Parser(26892): Error parsing data org.json.JSONException: Value 2013-09-26 of type java.lang.String cannot be converted to JSONObject
Когда я пытаюсь запустить следующий PHP «check_mail.php» через браузер на мой сервер работает и дает мне следующий код:
