Android and Microsoft SQL (MS SQL SERVER 2008) marriage

All you have to do is use the appropriate driver, being a opensource fan , i'd recommend using JTDS.

 Instructions below assumes you are using



  • Android Developer Tools Build id: v22.0.1-685705,
  • Eclipse Version: 4.2.1.v20130118 Build id: M20130204-1200
  • JTDS 1.2.5 

    • Though things will work out other versions higher than this and possibly lower as well , its just to ensure a known state where things worked out.

     So, once the JTDS is jar is download, first step is to include jar to your build path



    Next, it seems like a bug, go to order and Export tab and enable jtds


    Since the database connection operation is networked related, all network operations should be in different thread away from the main UI thread,  so use  AsyncTask.
    Working code is can be downloaded from here , read the code, it is well documented.

        Its always better to make use of RESTApi to access your database contents, so that data access becomes transparent [hiding the connection details etc] . However for php case, i suppose your are talking to MSSQL server on the same server, ie php file and database on same machine.

        http://www.w3schools.com/php/php_mysql_connect.asp

        This is as simple as explained in the above link.
