Facebookは発砲onCancel

Question

私はスレッド：Android Facebook 4.0 SDK How to get Email, Date of Birth and gender of Userを読んでいましたが、facebookのログインを呼び出すのにまったく同じコードを使用していますが、いつも私が間違っている方法onCancelを発射していますか？

public class LoginActivity extends AppCompatActivity { 

    CoordinatorLayout BackgroundImage; 
    int[] images = new int[] {R.drawable.bg01, R.drawable.bg02, R.drawable.bg03}; 
    Button BtnIniciar; 
    TextView BtnRecuperar; 
    EditText txtCorreo; 
    EditText txtContrasena; 
    String androidId; 
    TextView btnRegistrar; 
    LoginButton loginButton; 
    CallbackManager callbackManager; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     FacebookSdk.sdkInitialize(getApplicationContext()); 
     setContentView(R.layout.activity_login); 


     BackgroundImage = (CoordinatorLayout)findViewById(R.id.background); 
     int imageId = (int)(Math.random() * images.length); 
     BackgroundImage.setBackgroundResource(images[imageId]); 

     BtnIniciar = (Button) findViewById(R.id.Iniciar); 
     BtnRecuperar = (TextView) findViewById(R.id.btnRecuperar); 

     txtCorreo = (EditText) findViewById(R.id.txtCorreo); 
     txtContrasena = (EditText) findViewById(R.id.txtContrasena); 
     btnRegistrar = (TextView) findViewById(R.id.btnRegistrar); 

     androidId = Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID); 

     Boolean isLogged = new HttpGetPost().IsLogged(androidId); 

     if(isLogged){ 
      Intent intent = new Intent(LoginActivity.this, MainActivity.class); 
      startActivity(intent); 
     } 

     BtnIniciar.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       boolean result = new HttpGetPost().Login(txtCorreo.getText().toString(), txtContrasena.getText().toString(), 2, androidId); 
       if (result) { 
        Intent intent = new Intent(v.getContext(), MainActivity.class); 
        startActivity(intent); 
       } else { 
        Toast.makeText(v.getContext(), "El usuario/contraseña no es válido.", Toast.LENGTH_LONG).show(); 
       } 
      } 
     }); 

     BtnRecuperar.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Intent intent = new Intent(v.getContext(), RecuperarContrasena.class); 
       startActivity(intent); 
      } 
     }); 

     btnRegistrar.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Intent intent = new Intent(v.getContext(), RegistroActivity.class); 
       startActivity(intent); 
      } 
     }); 

     //MultiDex.install(this); 

     loginButton = (LoginButton) findViewById(R.id.login_button); 

     loginButton.setReadPermissions(Arrays.asList(
       "public_profile", "email", "user_birthday", "user_friends")); 

     callbackManager = CallbackManager.Factory.create(); 

     // Callback registration 
     loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() { 
      @Override 
      public void onSuccess(LoginResult loginResult) { 
       // App code 
       GraphRequest request = GraphRequest.newMeRequest(
         loginResult.getAccessToken(), 
         new GraphRequest.GraphJSONObjectCallback() { 
          @Override 
          public void onCompleted(JSONObject object, GraphResponse response) { 
           Log.v("LoginActivity", response.toString()); 

           // Application code 
           // String email = object.getString("email"); 
           // String birthday = object.getString("birthday"); // 01/31/1980 format 
          } 
         }); 
       Bundle parameters = new Bundle(); 
       parameters.putString("fields", "name,email"); 
       request.setParameters(parameters); 
       request.executeAsync(); 


      } 

      @Override 
      public void onCancel() { 
       // App code 
       Log.v("LoginActivity", "cancel"); 
      } 

      @Override 
      public void onError(FacebookException exception) { 
       // App code 
       Log.v("LoginActivity", exception.getCause().toString()); 
      } 
     }); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     callbackManager.onActivityResult(requestCode, resultCode, data); 
    } 

    @Override 
    public void onBackPressed() { 
     return; 
    }
