Nachrüstung 2 OkHttpClient Caching funktioniert nicht

Also hier ist das Problem, ich versuche, Caching für meine App zu implementieren, und ich folgte diesem Tutorial Android: Cache network requests for offline access with Retrofit2 and OkHTTP3, um es zu tun. Leider sind zwischengespeicherten Antworten nicht angezeigt werden, wenn es keine Internet-Verbindung ist, statt dieNachrüstung 2 OkHttpClient Caching funktioniert nicht

Toast.makeText (getContext(), getContext(). GetResources(). GetString (R.string.error_failed_to_load_posts), Toast. LENGTH_SHORT) .show();

wird ausgeführt. Kann mir jemand sagen, was ich falsch mache? Oder führen Sie mich, um eine Antwort auf dieses Problem zu bekommen? Ich werde zusätzliche Informationen bei Bedarf veröffentlichen, wenn Sie mich fragen. Unten ist der gesamte Code der spezifischen Funktion.

private void loadHomeLoggedPosts(String uid) { 
    progressBar.setVisibility(View.VISIBLE); 

    OkHttpClient client = new OkHttpClient 
      .Builder() 
      .cache(new Cache(getContext().getCacheDir(), 10 * 1024 * 1024)) // 10 MB 
      .addInterceptor(new Interceptor() { 
       @Override public okhttp3.Response intercept(Chain chain) throws IOException { 
        Request request = chain.request(); 
        if (Utils.isNetworkAvailable(getContext())) { 
         request = request.newBuilder().header("Cache-Control", "public, max-age=" + 60).build(); 
        } else { 
         request = request.newBuilder().header("Cache-Control", "public, only-if-cached, max-stale=" + 60 * 60 * 24 * 7).build(); 
        } 
        return chain.proceed(request); 
       } 
      }) 
      .build(); 

    Gson gson = new GsonBuilder() 
      .setLenient() 
      .create(); 

    Retrofit retrofit = new Retrofit.Builder() 
      .baseUrl(getResources().getString(R.string.app_base_url)) 
      .client(client) 
      .addConverterFactory(GsonConverterFactory.create(gson)) 
      .build(); 

    RequestInterface request = retrofit.create(RequestInterface.class); 
    Call<Classes> call = request.homeLoggedPosts(uid); 
    call.enqueue(new Callback<Classes>() { 
     @Override 
     public void onResponse(Call<Classes> call, Response<Classes> response) { 
      Classes jsonResponse = response.body(); 
      if (jsonResponse!=null) { 
       homePosts = jsonResponse.getHomePosts(); 
       homeLoggedInAdapter = new HomeLoggedInAdapter(homePosts); 
       recyclerView.setAdapter(homeLoggedInAdapter); 
       homeLoggedInAdapter.notifyDataSetChanged(); 
      } 
      else { 
       Toast.makeText(getContext(), getContext().getResources().getString(R.string.error_failed_to_load_posts), Toast.LENGTH_SHORT).show(); 
      } 
      progressBar.setVisibility(View.INVISIBLE); 
     } 

     @Override 
     public void onFailure(Call<Classes> call, Throwable t) { 
      progressBar.setVisibility(View.INVISIBLE); 
      Toast.makeText(getContext(), getContext().getResources().getString(R.string.error_failed_to_load_posts), Toast.LENGTH_SHORT).show(); 
      Log.d("ERROR", t.getMessage()); 
     } 
    }); 
}

EDIT: Ich habe zwei Funktionen in der gleichen Berufung Fragment wie folgt:

if (FirebaseAuth.getInstance().getCurrentUser()!=null) { 
     loadHomeLoggedPosts(FirebaseAuth.getInstance().getCurrentUser().getUid()); 
    } 
    else { 
     loadHomeNotLoggedPosts(); 
    }

ich den Code für loadHomeLoggedPosts oben gepostet habe. loadHomeNotLoggedPosts ist das gleiche mit ihm Unterschied nur dieser Abschnitt zu sein:

RequestInterface request = retrofit.create(RequestInterface.class); 
Call<Classes> call = request.homeNotLoggedPosts();

Farmaan Elahis' Antwort für loadHomeNotLoggedPosts funktioniert, aber nicht für loadHomeLoggedPosts. Jede Hilfe wird sehr geschätzt. Vielen Dank!

Okhttp log: Ich habe einige Teile bearbeitet, da das Protokoll zu groß war, um es hier vollständig zu veröffentlichen.

Sie den Code unten verwenden, können Sie okhttp Client zu bauen, die sowohl online als Cache haben können, die 2 gilt für Minuten sowie Offline-Cache, der für 7 Tage gültig ist.

PS: Sie müssen die App zum ersten Mal mit Internet verbunden Show prüfen, öffnen, die es nicht Ausnahme

private static OkHttpClient provideOkHttpClient() 
     { 
      return new OkHttpClient.Builder() 
        .addInterceptor(provideOfflineCacheInterceptor()) 
        .addNetworkInterceptor(provideCacheInterceptor()) 
        .cache(provideCache()) 
        .build(); 
     } 

     private static Cache provideCache() 
     { 
      Cache cache = null; 
      try 
      { 
       cache = new Cache(new File(getApplicationContext().getInstance().getCacheDir(), "http-cache"), 
         10 * 1024 * 1024); // 10 MB 
      } 
      catch (Exception e) 
      { 
       Timber.e(e, "Could not create Cache!"); 
      } 
      return cache; 
     } 

     public static Interceptor provideCacheInterceptor() 
     { 
      return new Interceptor() 
      { 
       @Override 
       public Response intercept (Chain chain) throws IOException 
       { 
        Response response = chain.proceed(chain.request()); 

        // re-write response header to force use of cache 
        CacheControl cacheControl = new CacheControl.Builder() 
          .maxAge(2, TimeUnit.MINUTES) 
          .build(); 

        return response.newBuilder() 
          .header(CACHE_CONTROL, cacheControl.toString()) 
          .build(); 
       } 
      }; 
     } 

     public static Interceptor provideOfflineCacheInterceptor() 
     { 
      return new Interceptor() 
      { 
       @Override 
       public Response intercept (Chain chain) throws IOException 
       { 
        Request request = chain.request(); 

        if (!AndroidUtils.isNetworkAvailable()) 
        { 
         CacheControl cacheControl = new CacheControl.Builder() 
           .maxStale(7, TimeUnit.DAYS) 
           .build(); 

         request = request.newBuilder() 
           .cacheControl(cacheControl) 
           .build(); 
        } 

        return chain.proceed(request); 
       } 
      }; 
     }

Ordnung wirft, werde ich überprüfen und lassen Sie wissen. Vielen Dank. –

Danke, es hat funktioniert! Lustige Geschichte, ich hatte bereits diesen Code aus [SsKarthi/Retrofit2.0-with-Cache] (https://github.com/SsKarthi/Retrofit2.0-with-Cache) versucht, aber zu der Zeit war es nicht Arbeit, jetzt tat es: D –

Dieser Code ist von caster.io android tutorial.Sie sind wirklich gut.Sie sollten sie auschecken –
