Just a pointer on PHP. There is no sanitizing of the input variables (POST) nor use of prepared statements (mysqli), so this is wide open to SQL injection.

Thanks for this great tut.i am using my mobile handset for running app so what is the ip for connecting database 127.0.0.1, 10.0.3.2 or 10.0.2.2
Thanks! This is great. I do have a couple of questions though:
1) How does the java code know that the `main_login()` function in the main.java file needs be ran after the 'login' button is clicked? I don't see an `event listener`, so I'm confused about this.
2) In Main.java, within the 'protected String doInBackground(String… params)' function, why does the data in 'return data' get passed into 'String s' on the 'onPostExecute' function? Is it because they're within the same class, so the returned data from the 'doInBackground' function gets passed directly into the 'onPostExecute' function?
