This is the connexion string that worked for me :

"jdbc:jtds:sqlserver://"+ adresseip +":1433/lear_db;user=youruser;password=yourpass"

than i got an other error wich is : android.os.NetworkOnMainThreadException

the solution is to use AsyncTask this is a tutorial : http://droidapp.co.uk/2011/05/12/android-dev-pre-loading-with-asynctask/

now i'm having a new error ( This errors never ends ) :

Unknow server host name 'unable to resolve host

Than it worked , on wifi with ip adresse of the host .

Usually, I use jdbc:sqlserver in this fasion

String url = "jdbc:sqlserver://10.0.2.2:1433/lear_db;instance=SQLEXPRESS;";

or alternatively if using jtds, try:

String url = "jdbc:jtds://10.0.2.2:1433/lear_db;instance=SQLEXPRESS;";
