public class Registration extends Activity{
private static final String SOAP_ACTION = "http://tempuri.org/register";
private static final String OPERATION_NAME = "register";
private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
private static final String SOAP_ADDRESS = "http://10.0.2.2:54714/WebSite1/Service.asmx";
Button sqlRegister, sqlView;

EditText  sqlFirstName,sqlLastName,sqlEmail,sqlMobileNumber,sqlCurrentLocation,sqlUsername,sqlPassword;

@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.registration);
sqlFirstName = (EditText) findViewById(R.id.etFname);
sqlLastName = (EditText) findViewById(R.id.etLname);
sqlEmail = (EditText) findViewById(R.id.etEmail);
sqlMobileNumber = (EditText) findViewById(R.id.etPhone);
sqlCurrentLocation = (EditText) findViewById(R.id.etCurrentLoc);

sqlUsername = (EditText) findViewById(R.id.etUsername);
sqlPassword = (EditText) findViewById(R.id.etPwd);

sqlRegister = (Button) findViewById(R.id.bRegister);

sqlRegister.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {
        switch (v.getId()){
        case R.id.bRegister:

                String firstname = sqlFirstName.getText().toString();
                String lastname = sqlLastName.getText().toString();
                String emailadd = sqlEmail.getText().toString();
                String number = sqlMobileNumber.getText().toString();
                String loc = sqlCurrentLocation.getText().toString();
                String uname = sqlUsername.getText().toString();
                String pwd = sqlPassword.getText().toString();

                SoapObject Request = new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME);
                Request.addProperty("fname", String.valueOf(firstname));
                Request.addProperty("lname", String.valueOf(lastname));

                Toast.makeText(Registration.this, "You have been registered Successfully", Toast.LENGTH_LONG).show();

                SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
                envelope.dotNet = true;
                envelope.setOutputSoapObject(Request);
                HttpTransportSE httpTransport  = new HttpTransportSE(SOAP_ADDRESS);
                try
                {
                    httpTransport.call(SOAP_ACTION, envelope);
                    SoapObject response = (SoapObject)envelope.getResponse();
                    int result =  Integer.parseInt(response.getProperty(0).toString());
                    if(result == '1'){
                        Toast.makeText(Registration.this, "You have been registered Successfully", Toast.LENGTH_LONG).show();
                    }
                    else
                    {
                        Toast.makeText(Registration.this, "Try Again", Toast.LENGTH_LONG).show();
                    }
                }
                catch(Exception e)
                {
                   e.printStackTrace();
                }

            break;
        }
           }
        });
    }

Answer 1

Pretty simple reason why you're getting an Application Not Responding error: you are making the web request on the main (UI) thread. There are two rules to the Android threading model: 1) don't block the main thread for more than a couple seconds 2) don't update the UI from off of the main thread. You are violating the first of those rules. You should look into using AsyncTask to do your longer operations.

Answer 2

httpTransport.call(SOAP_ACTION, envelope); You are making a network call on the UI thread. You need to do all long running tasks, such as accessing a resource over the network on a separate thread. The API provides a convenience class call [AsyncTask][1] that lets you accomplish this easily.

In its simplest form, you would create a class that extends AsyncTask, and then move your httpTransport.call(SOAP_ACTION, envelope); to its doInBackground method.
