Recently I have tried to connect to SQL Database server which is in my local network machine. I can connect and access SQL server from my Android app. I did it in the following way….
1. First of all you need a JDBC driver library for SQL Server. As we know android library has only SQLite database driver. So first download an open source JDBC driver from this http://jtds.sourceforge.net/ site (I downloaded the Linux version).
2. Then import the jar file into your Android app.(jtds-1.2.5.jar).
3. Now just try this code by modifying according to your context
