任何方式來緩存谷歌雲端點的查詢結果？

我需要存儲查詢的結果，我上次在本地客戶端android應用程序上觸發以立即使用數據。更新的數據可以在以後從AsyncTack或線程中獲取任何方式來緩存谷歌雲端點的查詢結果？

，生成的客戶端庫返回的對象是延伸GenericJson

類的有任何方法將其轉換成在sharedpreferences字符串和存儲以後再次實例化對象？

public class MainListingsUpdate extends AsyncTask<Void, Void, Void> { 

    private CollectionResponseMainEventListing list = new CollectionResponseMainEventListing(); 
    private DualCache<CollectionResponseMainEventListing> cache; 

    @Override 
     protected Void doInBackground(Void... voids) { 
      try { 
       list = mainActivityConnect.getAppUserApi().getMainListings().execute(); 



     SizeOf<CollectionResponseMainEventListing> sizeOf = new SizeOf<CollectionResponseMainEventListing>() { 
       @Override 
       public int sizeOf(CollectionResponseMainEventListing object) { 
        return object.toString().getBytes().length; 
       } 
      }; 

     cache = new DualCacheBuilder<>(Constants.cacheName, 1, CollectionResponseMainEventListing.class) 
        .useReferenceInRam(Integer.MAX_VALUE, sizeOf) 
        .useDefaultSerializerInDisk(Integer.MAX_VALUE, true); 

     cache.put("OBJECT_KEY", list); 

      } catch (IOException e) { 
       queryComplete = false; 
      } 
      return null; 
     } 

    }

http://stackoverflow.com/questions/15281164/approach-to-serialize-cloud-endpoint-model-class-to-android-file-system（2日回答）展示瞭如何序列化和重新加載任何GenericJson來自/從'byte []' - 當然如果你願意，你可以根據這些字符建立/解析字符串。 – 2015-02-01 01:00:56

我已經在這裏回答我的同一個問題：http://stackoverflow.com/questions/33485491/how-to-cache-the-response-in-google-cloud-endpoint/34218778#34218778 – penduDev 2015-12-11 08:20:54

@penduDev，我用了現成的圖書館爲它https://github.com/vincentbrison/android-easy-cache – 2015-12-13 07:08:25

我通過使用上述文庫實現驚人的文庫

android-easy-cache

示例代碼解決了這個問題，其簡單程度如下：

cache.get("OBJECT_KEY");
