Noted that you must have enabled TCP/IP in SQL Server. If you change TCP/IP you must restart SQL Server Service.
@SuppressLint("NewApi")
public Connection connectionclass() {
Connection con = null;
String ip = "172.1.0.1", port = "1433", username = "sa", password = "row@129", databasename = "CRUDAndroidDB";
StrictMode.ThreadPolicy tp = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(tp);
try {
Class.forName("net.sourceforge.jtds.jdbc.Driver");
String connectionUrl = "jdbc:jtds:sqlserver://" + ip + ":" + port + ";databasename=" + databasename + ";User=" + username + ";password=" + password + ";";
con = DriverManager.getConnection(connectionUrl);
} catch (Exception exception) {
Log.e("Error", exception.getMessage());
}
return con;
}
-- Code in onCreate event
TextView id = (TextView) findViewById(R.id.edittexid);
TextView name = (TextView) findViewById(R.id.edittextname);
TextView address = (TextView) findViewById(R.id.edittextaddress);
Button btninsert = (Button) findViewById(R.id.btnadd);
Button btnupdate = (Button) findViewById(R.id.btnupdate);
Button btndelete = (Button) findViewById(R.id.btndelete);
Button btnget = (Button) findViewById(R.id.btnget);
btninsert.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Connection connection = connectionclass();
try {
if (connection != null) {
String sqlinsert = "Insert into UserInfo_Tab values ('" + id.getText().toString() + "','" + name.getText().toString() + "','" + address.getText().toString() + "')";
Statement st = connection.createStatement();
ResultSet rs = st.executeQuery(sqlinsert);
}
} catch (Exception exception) {
Log.e("Error", exception.getMessage());
