Android + MySQL using com.mysql.jdbc.Driver

Use JDBC connector mysql-connector-java-3.0.17-ga-bin.jar, for now is the only one that works.

Check your code also, you need to implement a pool of connections for each activity of your application, just add a private "Connection" var and initialize that in your OnCreate method like con = DriveManager.getConnection...... then use that private var every time you need to access MYSQL.

An other approach is to use a Virtual JDBC Driver that uses a three-tier architecture: your JDBC code is sent through HTTP to a remote Servlet that filters the JDBC code (configuration & security) before passing it to the MySql JDBC Driver. The result is sent you back through HTTP. There are some free software that use this technique. Just Google "Android JDBC Driver over HTTP".
