Android SQL Connection with JDBC – Part 2

I managed to connect to the SQL Server with JDBC! This is a big progress for this project. The only thing remains in my mind is the design plan. I have to handle this ASAP because of obvious reasons.I use a string variable to send query to the server and get whatever i want. Lets say i want to get someones data from the database. I use the related class for the job (GetDataEmployee) and send the requested lines with it and voala. I gotta keep this project clean and organized so im planning to use just the right amount of classes. Also i have to search some good layouts for android so i can make the app little bit pretty.
