I want to connect a mobile application (Android) with MySQL restful web service to do the following

1- save the data of the client user (Android Mobile Application) to MySQL Restful data base
which is:-

a- User Login (User Name & Password).

b- Location of the mobile (Longitude & Latitude).

i have already created the restful web service linked with MySQL Data Base and created

attributes in the Database table (ID , User Name , Password , Longitude , Latitude)

i want to know 1- how to connect the client (the android mobile) with the rest and 2- how

to fill the database with the info coming from the client ??

Thanks in advance
