in signin the method gettext must be called from ui thread error - gettext

Question

I'm trying to create a login for an application. However I have a problem.
This is my code:
in this code there is an error in the getText() in the android studio
actually m creating a login page with the help of the JSONParsing of web API, the login detail sync from the web api
public class Register extends Activity implements OnClickListener{
EditText user, pass, email, mobile;
private Button mRegister;
// Progress Dialog
private ProgressDialog pDialog;
// JSON parser class
JSONParser jsonParser = new JSONParser();
//si lo trabajan de manera local en xxx.xxx.x.x va su ip local
// private static final String REGISTER_URL = "http://xxx.xxx.x.x:1234/cas/register.php";
//testing on Emulator:
private static final String REGISTER_URL = "http://abc.demo.xxxxxxxxx.xxx/xxx";
//ids
private static final String TAG_SUCCESS = "success";
private static final String TAG_MESSAGE = "message";
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.register);
user = (EditText)findViewById(R.id.username);
pass = (EditText)findViewById(R.id.password);
email = (EditText)findViewById(R.id.Email);
mobile = (EditText)findViewById(R.id.etmobile);
mRegister = (Button)findViewById(R.id.register);
mRegister.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
new CreateUser().execute();
}
class CreateUser extends AsyncTask<String, String, String> {
#Override
protected void onPreExecute() {
super.onPreExecute();
pDialog = new ProgressDialog(Register.this);
pDialog.setMessage("Creating User...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
#Override
protected String doInBackground(String... args) {
// TODO Auto-generated method stub
// Check for success tag
int success;
String username = user.getText().toString();
String password = pass.getText().toString();
String mobile = mobile.getText().toString();
String email = email.getText().toString();
try {
// Building Parameters
List params = new ArrayList();
params.add(new BasicNameValuePair("username", username));
params.add(new BasicNameValuePair("password", password));
params.add(new BasicNameValuePair("email", email));
params.add(new BasicNameValuePair("mobile", mobile));
Log.d("request!", "starting");
//Posting user data to script
JSONObject json = jsonParser.makeHttpRequest(
REGISTER_URL, "POST", params);
// full json response
Log.d("Registering attempt", json.toString());
// json success element
success = json.getInt(TAG_SUCCESS);
if (success == 1) {
Log.d("User Created!", json.toString());
finish();
return json.getString(TAG_MESSAGE);
}else{
Log.d("Registering Failure!", json.getString(TAG_MESSAGE));
return json.getString(TAG_MESSAGE);
}
} catch (JSONException e) {
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String file_url) {
// dismiss the dialog once product deleted
pDialog.dismiss();
if (file_url != null){
Toast.makeText(Register.this, file_url, Toast.LENGTH_LONG).show();
}
}
}
}

You will have to pass EditText values as args in the Async task.
String[] params = {user.getText().toString(),
pass.getText().toString(),
mobile.getText().toString(),
email.getText().toString()};
new CreateUser().execute(params);
You can play with the UI elements only in classes that run in UI thread. Activity or fragments etc.
