NetworkOnMainThreadException crashes android app - networkonmainthread

Question

I built a webservice and tested it with SoapUI and everything is ok. Now when I try to submit the form to register an user, I get NetworkOnMainThreadException error. It looks the main thread is having to much work.
Can you help me with AsyncTask and doInBackground() method? Where and how should I do that? On my user register layout class (RegUser.java) or where the insert method is (UserDAO.java)?
RegUser.java
public class RegUser extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user);
final EditText username = (EditText) findViewById(R.id.username);
final EditText email = (EditText) findViewById(R.id.email);
final EditText password = (EditText) findViewById(R.id.password);
final EditText salt = (EditText) findViewById(R.id.salt);
final EditText nome = (EditText) findViewById(R.id.nome);
final EditText sobrenome = (EditText) findViewById(R.id.sobrenome);
final EditText telefone = (EditText) findViewById(R.id.telefone);
final EditText cel_wts = (EditText) findViewById(R.id.cel_wts);
final EditText rua = (EditText) findViewById(R.id.rua);
final EditText numero = (EditText) findViewById(R.id.numero);
final EditText bairro = (EditText) findViewById(R.id.bairro);
final EditText cidade = (EditText) findViewById(R.id.cidade);
final EditText estado = (EditText) findViewById(R.id.estado);
final EditText pais = (EditText) findViewById(R.id.pais);
final EditText cpf_cnpj = (EditText) findViewById(R.id.cpf_cnpj);
final EditText empresa= (EditText) findViewById(R.id.empresa);
final EditText cargo = (EditText) findViewById(R.id.cargo);
final Button cadProfile = (Button) findViewById(R.id.cadProfile);
cadProfile.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
UserDAO dao = new UserDAO();
boolean resultado = dao.insertUser(new User(0, username.getText().toString(),
email.getText().toString(),
password.getText().toString(),
salt.getText().toString(),
nome.getText().toString(),
sobrenome.getText().toString(),
telefone.getText().toString(),
cel_wts.getText().toString(),
rua.getText().toString(),
numero.getText().toString(),
bairro.getText().toString(),
cidade.getText().toString(),
estado.getText().toString(),
pais.getText().toString(),
cpf_cnpj.getText().toString(),
empresa.getText().toString(),
cargo.getText().toString()));
if(resultado){
finish();
}else{
Toast.makeText(RegUser.this, "Erro ao cadastrar :(", Toast.LENGTH_LONG).show();
}
}
});
}
}
UserDAO.java
public class UserDAO {
private static final String URL = "...meuIP:8080/Meuprojeto/services/EventoDAO?wsdl";
private static final String NAMESPACE = "...meuprojetoWS.habitodigital.com";
private static final String INSERIR = "insertUser";
private static final String EXCLUIR = "deletetUser";
private static final String ATUALIZAR = "updateUser";
private static final String BUSCAR_TODOS = "searchAllUsers";
private static final String BUSCAR_POR_ID = "searchUserById";
public boolean insertUser(User user){
SoapObject insertUser = new SoapObject(NAMESPACE, INSERIR);
SoapObject usr = new SoapObject(NAMESPACE, "user");
usr.addProperty("id", user.getId());
usr.addProperty("username", user.getUsername());
usr.addProperty("email", user.getEmail());
usr.addProperty("password", user.getPassword());
usr.addProperty("salt", user.getSalt());
usr.addProperty("nome", user.getNome());
usr.addProperty("sobrenome", user.getSobrenome());
usr.addProperty("telefone", user.getTelefone());
usr.addProperty("cel_wts", user.getCel_wts());
usr.addProperty("rua", user.getRua());
usr.addProperty("numero", user.getNumero());
usr.addProperty("bairro", user.getBairro());
usr.addProperty("cidade", user.getCidade());
usr.addProperty("estado", user.getEstado());
usr.addProperty("pais", user.getPais());
usr.addProperty("cpf_cnpj", user.getCpf_cnpj());
usr.addProperty("empresa", user.getEmpresa());
usr.addProperty("cargo", user.getCargo());
insertUser.addSoapObject(usr);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(insertUser);
envelope.implicitTypes = true;
HttpTransportSE http = new HttpTransportSE(URL);
try {
http.call("urn:" + INSERIR, envelope);
SoapPrimitive resposta = (SoapPrimitive) envelope.getResponse();
return Boolean.parseBoolean(resposta.toString());
} catch (Exception e) {
e.printStackTrace();
return false;
}
}
}

Answer 1

I should do it in the userDOA.java. The ASynctask will look like this.
AsyncTask<String, Void, Boolean) task =new AsyncTask<String, Void, Boolean>() {
#Override
protected Boolean doInBackground(String... params) {
HttpTransportSE http = new HttpTransportSE(URL);
try {
http.call("urn:" + INSERIR, envelope);
SoapPrimitive resposta = (SoapPrimitive) envelope.getResponse();
return Boolean.parseBoolean(resposta.toString());
} catch (Exception e) {
//handle exception
}
}
#Override
protected void onPostExecute(Boolean result) {
//Do something with result
}
}
You need to call it like
task.execute(params);
Hope this helps.
