Android does not find the local variable, but does not exist

Question

Hello I’m running a debug on this code and at the end it gives this message in debug.

Cannot find local variable 'Namespace'

However I already searched all my code and I do not find this variable do not know what to do thinking of redoing the code I do not know if it can be a garbage that is in some file.

But before that I was wondering if you’ve ever had anything like this.

public class CriarPrato extends AppCompatActivity {

private Spinner LocalRestaurante;
private Spinner NomeRestaurante;
private EditText NomePrato;
private EditText PrecoPrato;
private Button GerarPrato;
private String IDrestaurante;



@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_criar_prato);

    LocalRestaurante = (Spinner) findViewById(R.id.SpinerLocalPrato);
    NomeRestaurante = (Spinner) findViewById(R.id.spinnerNomeRestaurantePrato);
    NomePrato = (EditText) findViewById(R.id.editTextNomePrato);
    PrecoPrato = (EditText) findViewById(R.id.editTextPrecoPrato);
    GerarPrato = (Button) findViewById(R.id.buttonPrato);

    Query queryPrato = ConfiguracaoFirebase.getReferencia().child("Restaurante").orderByChild("localRestaurante");

    queryPrato.addListenerForSingleValueEvent(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            final List<String> localRest = new ArrayList<String>();
            final List<String> NomeRestauranteList = new ArrayList<String>();

            for (DataSnapshot data : dataSnapshot.getChildren()) {
                Restaurante restaurante = data.getValue(Restaurante.class);
                localRest.add(restaurante.getLocalRestaurante().toString());
                NomeRestauranteList.add(restaurante.getNome().toString());
            }

            LocalRestaurante = (Spinner) findViewById(R.id.SpinerLocalPrato);
            ArrayAdapter<String> areas = new ArrayAdapter<String>(getApplicationContext(), R.layout.spinner_item, localRest);
            areas.setDropDownViewResource(R.layout.spinner_item);
            LocalRestaurante.setAdapter(areas);

            NomeRestaurante = (Spinner) findViewById(R.id.spinnerNomeRestaurantePrato);
            ArrayAdapter<String> NomeRestAdapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.spinner_item, NomeRestauranteList);
            NomeRestAdapter.setDropDownViewResource(R.layout.spinner_item);
            NomeRestaurante.setAdapter(NomeRestAdapter);


        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }
    });

    GerarPrato.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Prato prato = new Prato();
            String NomeSelcRestaurante= NomeRestaurante.getSelectedItem().toString();
            Query queryPrato2 = ConfiguracaoFirebase.getReferencia().child("Restaurante").orderByChild("nome").equalTo(NomeSelcRestaurante);
            queryPrato2.addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot dataSnapshot) {
                    IDrestaurante = dataSnapshot.getValue().toString();
                }

                @Override
                public void onCancelled(DatabaseError databaseError) {

                }
            });
            prato.setNomePrato(NomePrato.getText().toString());
            prato.setPrecoPrato("R$"+ PrecoPrato.getText().toString());
            prato.setID(IDrestaurante);
            prato.Salvar(IDrestaurante);
        }
    });


}

Answer 1

I suggest that a CONTROL+SHIFT+F and do a full search for this variable, if you find it remove and your project will compile. If the variable in question does not act on your project, go to Build -> Clean Project and then go on Build -> Rebuild Project to rebuild your entire project again.
