  1. Eu criei duas classes customizadas de acordo com o que foi orientado por meu professor para fazer a requisição no servidor, mas estou recebendo um retorno 400 e não consigo descobrir a razão. Pesquisando, vi que pode ser algo relacionado ao cabeçalho, mas não sei como enviá-lo na minha requisição JSon customizada. Este é o código do meu do meu código customizado para requisição de JsonObject: package com.example.sandrini.pokeagenda; import com.android.volley.AuthFailureError; import com.android.volley.Response; import com.android.volley.RetryPolicy; import com.android.volley.toolbox.JsonObjectRequest; import org.json.JSONObject; import java.util.HashMap; import java.util.Map; public class CustomJSONObjectRequest extends JsonObjectRequest { public CustomJSONObjectRequest(int method, String url, JSONObject jsonRequest, Response.Listener<JSONObject> listener, Response.ErrorListener errorListener) { super(method, url, jsonRequest, listener, errorListener); } @Override public Map<String, String> getHeaders() throws AuthFailureError { HashMap<String, String> headers = new HashMap<>(); headers.put("Content-Type", "application/json; charset=utf-8"); return headers; } @Override public RetryPolicy getRetryPolicy() { return super.getRetryPolicy(); } } Este é o código da minha Request Queue: package com.example.sandrini.pokeagenda; import android.content.Context; import com.android.volley.Cache; import com.android.volley.Network; import com.android.volley.RequestQueue; import com.android.volley.toolbox.BasicNetwork; import com.android.volley.toolbox.DiskBasedCache; import com.android.volley.toolbox.HurlStack; public class CustomVolleyRequestQueue { private static CustomVolleyRequestQueue mInstance; private static Context mCtx; private RequestQueue mRequestQueue; private CustomVolleyRequestQueue(Context context) { //recebe o contexto da aplicação //Assim a fila dura o ciclo de vida do app mCtx = context; mRequestQueue = getRequestQueue(); } public static synchronized CustomVolleyRequestQueue getmInstance(Context context) { if (mInstance == null) { mInstance = new CustomVolleyRequestQueue(context); } //retorna uma instância da fila return mInstance; } public RequestQueue getRequestQueue() { if (mRequestQueue == null) { //Cache 10MB Cache cache = new DiskBasedCache(mCtx.getCacheDir(), 10 *1024); Network network = new BasicNetwork(new HurlStack()); mRequestQueue = new RequestQueue(cache, network); mRequestQueue.start(); } return mRequestQueue; } } Este é o código da Activity onde estou tentando fazer a requisição: package com.example.sandrini.pokeagenda; import android.content.Intent; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.Button; import android.widget.EditText;

emailCreateInput = (EditText) findViewById(R.id.email_create_input); pwdCreateInput = (EditText) findViewById(R.id.pwd_create_input); createUserButton = (Button) findViewById(R.id.create_user_button); progressBarCreateUser = (ProgressBar) findViewById(R.id.progress_bar_create_user); progressBarCreateUser.setVisibility(View.INVISIBLE); } @Override protected void onStart() { super.onStart(); createUserButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if (loginCreateInput.getText().toString().equals("")) { Toast.makeText(getApplicationContext(), "Please, set a login", Toast.LENGTH_SHORT).show();

trainer.setPassword(pwdCreateInput.getText().toString());*/ trainer.setUsername("gato"); trainer.setEmail("gato"); trainer.setPassword("gato"); try { JSONObject jsonObject; Gson gson = new Gson(); String trainerToGson = gson.toJson(trainer); jsonObject = new JSONObject(trainerToGson); //String trainerToGson = "{\"username\":"+ "\"" + trainer.getUsername()+ "\"" + "," + //"\"email\":"+ "\"" + trainer.getEmail() + "\"" + "," + //"\"username\":"+ "\"" + trainer.getPassword()+ "\"" + "}"; //createUserButton.setText(trainerToGson); mQueue = CustomVolleyRequestQueue.getmInstance(CreateUserActivity.this.getApplicationContext()).getRequestQueue(); jsonRequest = new CustomJSONObjectRequest(Request.Method.POST, url, jsonObject, CreateUserActivity.this, CreateUserActivity.this); jsonRequest.getHeaders(); mQueue.add(jsonRequest); progressBarCreateUser.setVisibility(View.VISIBLE); } catch (Exception e) { e.printStackTrace(); } } } }); } @Override protected void onStop() { super.onStop(); if(mQueue != null) { mQueue.cancelAll(REQUEST_TAG); } } @Override public void onErrorResponse(VolleyError error) { progressBarCreateUser.setVisibility(View.INVISIBLE); Toast.makeText(getApplicationContext(), "Register failed", Toast.LENGTH_LONG).show(); Log.e("erro400", error.getMessage().toString()); Log.e("erro400", error.getCause().toString()); Log.e("erro400", error.getStackTrace().toString()); } @Override public void onResponse(Object trainerObject) { progressBarCreateUser.setVisibility(View.INVISIBLE); Toast.makeText(getApplicationContext(), "Registered successfully", Toast.LENGTH_LONG).show(); Intent intent = new Intent(CreateUserActivity.this, WelcomeTrainerActivity.class); startActivity(intent); finish(); } } Este é o meu Web Service: package ws; import com.google.gson.Gson; import dao.PokemonDAO; import dao.TrainerDAO; import java.util.ArrayList; import javax.ws.rs.core.Context; import javax.ws.rs.core.UriInfo;
