Retrofit - приложение падает, когда я звоню намерению открыть новую активность

Question

Я относительно новичок в android, и я только начал играть с модификацией. В настоящее время я делаю приложение в ресторане. Сначала я использовал volley, чтобы получить список ресторанов с сервера. Я загрузил информацию о ресторанах в местную базу данных и добавил ее в свой mapFragment и restaurantListFragment. Затем я решил начать использовать retrofit вместо волейбол. Мне удалось сделать то же самое с Retrofit - отобразить рестораны в моих двух фрагментах.

Но теперь У меня есть странные проблемы, которые, я думаю, не должно быть связано с дооснащения - если я пытаюсь открыть пристальный мое приложение падает. У меня есть navdrawer, который падает, когда я пытаюсь открыть из него активность. Также у меня была возможность добавить ресторан на длинный клик на карте. Longclick назвал бы намерение и открыл setRestaurantActivity. Он также падает.

Это то, что я получаю, когда пытаюсь открыть активность navdrawer.

Это как мой navdrawer выглядит (не изменилась после того, как я начал использовать переоснащение), и работал раньше:

public boolean onNavigationItemSelected(MenuItem item) { 
// Handle navigation view item clicks here. 
int id = item.getItemId(); 

if (id == R.id.nav_account) { 
    // Handle the account action 
    Intent accountIntent = new Intent(MainActivity.this, MyProfileActivity.class); 
    startActivity(accountIntent); 
} else if (id == R.id.nav_contacts) { 
    Intent contactsIntent = new Intent(MainActivity.this, FavouriteRestaurantsListActivity.class); 
    startActivity(contactsIntent); 
} else if (id == R.id.nav_blocked) { 
    Intent blockedIntent = new Intent(MainActivity.this, BlockedRestaurantsListActivity.class); 
    startActivity(blockedIntent); 
} else if (id == R.id.nav_logout) { 
    AlertDialog.Builder builder = new AlertDialog.Builder(this); 
    builder.setTitle(R.string.logging_out) 
      .setMessage(R.string.logout_yes_no) 
      .setCancelable(false) 
      .setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int id) { 
        logoutUser(); 
       } 
      }) 
      .setNegativeButton(R.string.no, null); 

    AlertDialog alert = builder.show(); 
    TextView messageText = (TextView) alert.findViewById(android.R.id.message); 
    if (messageText != null) { 
    messageText.setGravity(Gravity.CENTER); 
    } 
} 

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
drawer.closeDrawer(GravityCompat.START); 
return true; 
} 

И это призыв к setRestaurantActivity вызывается из моего фрагмента карты:

   mMap.setOnMapLongClickListener(new GoogleMap.OnMapLongClickListener() { 

       @Override 
       public void onMapLongClick(final LatLng arg0) { 

        RequestQueue queue = Volley.newRequestQueue(getActivity()); 
        String url = "https://maps.googleapis.com/maps/api/geocode/json?latlng=" + String.valueOf(arg0.latitude) + "," + String.valueOf(arg0.longitude) + "&key=myKey "; 

        // Request a string response from the provided URL. 
        StringRequest stringRequest = new StringRequest(Request.Method.GET, url, 
          new Response.Listener<String>() { 
           @Override 
           public void onResponse(String response) { 
            try { 
             JSONArray jObj = new JSONObject(response).getJSONArray("results").getJSONObject(0).getJSONArray("address_components"); 

             Intent intent = new Intent(getActivity(), SetRestaurantActivity.class); 

             for (int i = 0; i < jObj.length(); i++) { 
              String componentName = new JSONObject(jObj.getString(i)).getJSONArray("types").getString(0); 
              if (componentName.equals("postal_code") || componentName.equals("locality") || componentName.equals("street_number") || componentName.equals("route") 
                || componentName.equals("neighborhood") || componentName.equals("sublocality") || componentName.equals("administrative_area_level_2") 
                || componentName.equals("administrative_area_level_1") || componentName.equals("country")) { 
               intent.putExtra(componentName, new JSONObject(jObj.getString(i)).getString("short_name")); 
              } 
             } 

             intent.putExtra("latitude", arg0.latitude); 
             intent.putExtra("longitude", arg0.longitude); 

             startActivity(intent); 

            } catch (JSONException e) { 
             e.printStackTrace(); 
            } 
           } 
          }, new Response.ErrorListener() { 
         @Override 
         public void onErrorResponse(VolleyError error) { 
          int x = 1; 
         } 
        }); 
        queue.add(stringRequest); 

       } 
      });

Answer 1

От линии:

java.lang.RuntimeException: Parcel: unable to marshal value  com.weekendcoder.kemo.restaurant.model.Restaurant@2e7b673c 

один может вычитать, что Restaurant объект хочет записать в посылку , но этого не может быть, потому что Restaurant не является исчерпывающим.

Выполнение Restaurant класса реализует интерфейс Parcelable.
