HttpResponseCache和DiskLruCache的java.lang.NoClassDefFoundError

Question

我正在嘗試在新項目Android中測試此緩存庫。
當我運行該項目，我得到這樣的logcat：

這是我MainActivity.java：

我在libs文件夾複製從項目HttpResponseCache by Craig Andrews和DiskLruCache by Jake Wharton兩個罐子

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    final long httpCacheSize = 10 * 1024 * 1024; // 10 MiB 
    final File httpCacheDir = new File(getCacheDir(), "http"); 

    try { 
     com.integralblue.httpresponsecache.HttpResponseCache.install(httpCacheDir, httpCacheSize); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    }   
} 

我在其他線程看到它是訂單問題，所以在訂單&在Java構建路徑導出選項卡，我把這個排在首位：

我打掃proyect，重建並沒有什麼工作，問題仍然存在...
任何想法...？

謝謝。

Answer 1

因爲使用disklrucache-2.0.2.jar和httpresponsecache-1.3.jar

在圖書館httpresponsecache-1.3.jar使用disklrucache-1.2.1.jar

disklrucache-1.2.1.jar該軟件包是：com.jakewharton但在2.0.2版中該軟件包更改爲com.j akewharton.disklrucache

這是根本原因。

如果你想使用disklrucache你應該使用1.2.1版

你可以從這裏下載：http://www.mediafire.com/download/e2q4vz7kdlwxxr3/disklrucache-1.2.1.jar（.jar）文件

或源文件：https://www.mediafire.com/?933nqqe9j4227cc（.jar）文件

希望這可以幫到你。
