I don't know where the bug is. Hope someone can help me. Running it on real android device it returns "Incorrect user details" and howewer it doesn't send data to mysql server and then to database. If I run php files from chrome browser it works perfectly. I'm using wampp server as localhost. Thanks very much in advance.
