I am developing an application in Android Studio in which consumes a service I created in Play Framework.
This is my service route:
GET /Services/cadastrarPalheta/{matricula}/{data_instalacao}/{local}/{cod}/{estado}/{bairro}/{rua}/{complemento}/{pais}/{latitude}/{longitude}/{obs} Services.cadastrarPalheta
My kind of service:
public class Services extends Controller {
public static void cadastrarPalheta(String matricula, String data_instalacao, String local, String cod, String estado, String bairro,
String rua, String complemento, String pais, String latitude, String longitude) {
if (validation.hasErrors()) {
String mensagem = "Erro ao cadastrar";
JsonObject j = new JsonObject();
j.addProperty("Erro", 404);
j.addProperty("msg", mensagem);
renderJSON(j);
} else {
String msgsucess = "Cadastrado com sucesso!";
Endereco endereco = new Endereco();
endereco.estado = estado;
endereco.bairro = bairro;
endereco.local = local;
endereco.rua = rua;
endereco.complemento = complemento;
endereco.pais = pais;
endereco.latitude = latitude;
endereco.longitude = longitude;
endereco.save();
Agente funcionarioBanco = Agente.find("login = ?", matricula).first();
Palheta pal = new Palheta();
pal.agente = funcionarioBanco;
pal.codigo = cod;
DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
try {
pal.data_instalacao = formatter.parse(data_instalacao);
} catch (ParseException e) {
e.printStackTrace();
}
pal.endereco = endereco;
pal.save();
JsonObject j = new JsonObject();
j.addProperty("Success", 200);
j.addProperty("msg", msgsucess);
renderJSON(j);
}
}
My Android app:
public class FormPalhetasActivity extends Activity implements AdapterView.OnItemSelectedListener, LocationListener {
double latitude = 0;
double longitude = 0;
public static final String TAG = "LOG";
public static final String REGISTER_URL = "http://192.168.0.108:9000/Services/cadastrarPalheta";

String fmatr, flocal, fdata;
SimpleDateFormat formataData = new SimpleDateFormat("dd-MM-yyyy");
Date data = new Date();
String dataFormatada = formataData.format(data);
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.activity_form_palhetas );
Bundle inBundle = getIntent().getExtras();
fmatr = inBundle.get("username").toString();
frua = (EditText) findViewById(R.id.rua);

// Spinner element

categories.add("Construção");
// Creating adapter for spinner
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, categories);
// Drop down layout style - list view with radio button
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// attaching data adapter to spinner
spinner.setAdapter(dataAdapter);
readMyCurrentCoordinates();
Button enviar = (Button) findViewById( R.id.enviar );
enviar.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v) {
registerForms();
}
} );
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState( outState );
}
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
String item = parent.getItemAtPosition(position).toString();
if(position == 0){
flocal = "Terreno baldio";
}else if(position == 1){
flocal = "Esgoto a ceu aberto";
}else if(position == 2){
flocal = "Lixo";
}else if(position == 3){
flocal = "Piscina";
}else if(position == 4){
flocal = "Construção";
}else if(position == 5){
flocal = "Outros";
}
}
public void registerForms() {
final String address = frua.getText().toString().trim();
final String district = fbairro.getText().toString().trim();
final String city = fcidade.getText().toString().trim();
final String complement = fcompl.getText().toString().trim();
final String state = festado.getText().toString().trim();

StringRequest stringRequest = new StringRequest( Request.Method.POST, REGISTER_URL+"?matricula="+fmatr + "&data_instalacao="+dataFormatada+"&local="+flocal
+"&cod="+code+"&estado="+state+"&bairro="+district+"&rua="+address+"&complemento="+complement+"&pais="+pais+"&latitude="+latitude+"&longitude="+longitude
+"&obs="+note,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
if (response.contains("Erro")) {
Toast.makeText( FormPalhetasActivity.this, response, Toast.LENGTH_LONG ).show();
} else {
Intent intent = new Intent(FormPalhetasActivity.this, PrincipalActivity.class);
Toast.makeText( FormPalhetasActivity.this, response, Toast.LENGTH_LONG ).show();
startActivity(intent);
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText( FormPalhetasActivity.this, error.toString(), Toast.LENGTH_LONG ).show();
Log.i( TAG, "Lat: " + error );
}
} ) {
@Override
protected Map<String, String> getParams() {
Map<String, String> map = new HashMap<String, String>();
map.put( KEY_USERNAME, fmatr );
map.put( KEY_ADDRESS, address );
map.put( KEY_DISTRICT, district );
map.put( KEY_COMPLEMENT, complement );
map.put( KEY_CITY, city );
map.put( KEY_NOTE, note );
map.put( KEY_STATE, state );
map.put( KEY_COD, code );
map.put( KEY_LOCALE, flocal );
map.put( KEY_DATE, dataFormatada );
map.put( KEY_LAT, String.valueOf( latitude ) );
map.put( KEY_LONG, String.valueOf( longitude ) );
return map;
}
};
RequestQueue requestQueue = Volley.newRequestQueue( this );
requestQueue.add( stringRequest );
}
}
I am now learning to create and consume services, and am having the following error while running the application:
com.android.volley.NoConnectionError: java.io.IOException: unexpected end of stream on Connection{192.168.0.108:9000, proxy=DIRECT@ hostAddress=192.168.0.108 cipherSuite=none protocol=http/1.1} (recycle count=0)
try calling the address in your browser and see if you get the expected result, it may be some error on the server side.
