Question

Он всегда дает неправильные учетные данные, я дважды проверил базу данных, есть ли какие-то проблемы с кодом. Я новичок в студии android, Любая помощь будет оценена по достоинству.

Answer 1

Я использую jsoup library в post данные о из моих android приложений, и это способ проще, где пример

Document doc = Jsoup.connect("http://shaadi.web44.net/hello.php") 
       .data("username", uname) 
       .data("password", pass) 
       .userAgent("some user agent..or not...") 
       .timeout(30000) 
       .post(); 

String httpresponse = doc.text();
