NoClassDefFound錯誤：Logcat讀取$ 1表明內部類錯誤，但我沒有

我正在安裝一個tcp服務器，我能夠得到示例工作，但沒有將示例應用到我自己的應用程序。我不斷收到一個NoClassDefFound錯誤，並嘗試刪除內部類並創建單獨的類，但它似乎沒有工作。我已經包含了我的LogCats和java文件。

你在使用任何外部'.jar'文件嗎？如果是，則請嘗試[this]（http://stackoverflow.com/a/11824038/940096）或者，您是否在AndroidManifest.xml文件中聲明瞭所有活動？ – Praveenkumar 2012-08-07 14:46:57

我現在正在添加清單。我正在使用一個外部jar，但我已正確放入。 – 2012-08-07 15:21:34

@SamBevins你能指出代碼中的第103行嗎？ $符號表示匿名內部類。 – 2012-08-07 16:34:39

我不能確定有關錯誤的，但$ 1指一樣，你在這裏使用

private void onResponseReceived(Object sender, 
     final TypedResponseReceivedEventArgs<MyResponse> e) { 
    // Display the result - returned number of characters. 
    // Note: Marshal displaying to the correct UI thread. 
    myRefresh.post(new Runnable() { 
     public void run() { 
      myResponseEditText.setText(Integer.toString(e 
        .getResponseMessage().Length)); 
     } 
    }); 
}

從技術上講，你是一個匿名內部類（沒有名字的類）創建一個名爲$ 1的Runnable的子類，並且這個類是內部的。不知道錯誤是什麼，雖然我會嘗試重新編譯所有東西

奇怪的是，編碼與我的工作示例相同，不會返回任何錯誤。我如何重新編譯？ – 2012-08-07 15:20:19

@SamBevins然後嘗試清理您的項目，然後再試一次，或重新啓動IDE – 2012-08-07 15:37:38

我已經做到了多次，但我仍然有同樣的錯誤在我的問題 – 2012-08-07 15:57:17

你還沒有重新編譯所有東西。無論是你還是你的類路徑中有一個任性的入口。

我想我在想通了這個問題，

在清單文件的包被宣佈爲AndroidNetCommunicationClientActivityInner作爲

package="com.example.com.proto1"

但實際上你沒有在包類，而不是因爲在指定的JAVA文件中沒有包聲明。

但是android會尋找該類的包，因此會拋出java.lang.NoClassDefFoundError。

2012-08-07 18:15:58

好吧，我更換了兩個班，但我仍然有完全相同的問題 – 2012-08-08 13:25:08

@SamBevins問題是最有可能與包聲明的東西，你試圖找出它？ – 2012-08-08 13:47:27

我對編程相當陌生，所以我無法弄清楚問題所在。我試圖弄明白。我不明白的是我的示例代碼如何工作，但在我的實際應用程序中使用時不起作用。我檢查了所有的編碼，但它看起來是一樣的 – 2012-08-08 14:17:12

NoClassDefFound錯誤：Logcat讀取$ 1表明內部類錯誤，但我沒有
