hi in my app i am trying to check the username and password in database from webservice and if its true will show success message or failed message, but unable to show the status message
public class AndroidLoginExampleActivity extends Activity {
private final String NAMESPACE = "http://ws.userlogin.com";
private final String URL = "http://localhost:8080/Androidlogin/services/Login?wsdl";
private final String SOAP_ACTION = "http://ws.userlogin.com/authentication";
private final String METHOD_NAME = "authentication";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button login = (Button) findViewById(R.id.btn_login);
login.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
loginAction();
}
});
}
@SuppressLint("NewApi") private void loginAction(){
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
EditText userName = (EditText) findViewById(R.id.tf_userName);
String user_Name = userName.getText().toString();
EditText userPassword = (EditText) findViewById(R.id.tf_password);
String user_Password = userPassword.getText().toString();
//Pass value for userName variable of the web service
PropertyInfo unameProp =new PropertyInfo();
unameProp.setName("userName");//Define the variable name in the web service method
unameProp.setValue(user_Name);//set value for userName variable
unameProp.setType(String.class);//Define the type of the variable
request.addProperty(unameProp);//Pass properties to the variable
//Pass value for Password variable of the web service
PropertyInfo passwordProp =new PropertyInfo();
passwordProp.setName("password");
passwordProp.setValue(user_Password);
passwordProp.setType(String.class);
request.addProperty(passwordProp);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try{
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
TextView result = (TextView) findViewById(R.id.tv_status);
result.setText(response.toString());
Log.d("resp:",response.toString() );
}
catch(Exception e){
}
}
below is my webservice call
public class Login {
public String authentication(String userName,String password){
String retrievedUserName = "";
String retrievedPassword = "";
String status = "";
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb","root","root");
PreparedStatement statement = con.prepareStatement("SELECT * FROM user WHERE username = '"+userName+"'");
ResultSet result = statement.executeQuery();
while(result.next()){
retrievedUserName = result.getString("username");
retrievedPassword = result.getString("password");
}
if(retrievedUserName.equals(userName)&&retrievedPassword.equals(password)){
status = "Success!";
}
else{
status = "Login fail!!!";
}
}
catch(Exception e){
e.printStackTrace();
}
return status;
}
}
not sure were iam doing wrong.Any help is appreciated.

You should do network realted operation on a thread. You can use a thread or AsyncTask.
Move your loginAction() inside a thread or inside doInbackground of AsyncTask.
Remember not to update ui from the back ground thread.
new TheTask().execute();
AsyncTask
public class TheTask extends AsyncTask <Void,Void,Void>
{
@Override
protected void onPreExecute() {
super.onPreExecute();
// display a dialog
}
@Override
protected Void doInBackground(Void... params) {
// your login authentcation
// remove updation of textview.
// do not update ui here
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// dismiss the dialog
// update textview
}
}
AsyncTask docs

Edit:
public class MainActivity extends Activity {
private final String NAMESPACE = "http://ws.userlogin.com";

private final String SOAP_ACTION = "http://ws.userlogin.com/authentication";

/** Called when the activity is first created. */
EditText ed1,ed2;

}
catch(Exception e){

return response;

@Override

pd.dismiss();
if(result!=null)
tv.setText(result.toString());
