的NoClassDefFoundError的Android項目

首先，我知道有很多的問題/關於這個話題的答案，我讀過大部分，但仍然得到錯誤：的NoClassDefFoundError的Android項目

05-17 02:57:06.522: E/AndroidRuntime(17073): java.lang.NoClassDefFoundError: ar.com.package.android.MainActivity

項目工作就好了，直到我更新的Eclipse從21到22.

我試過了我所能做的一切：我檢查了清單;清理項目;檢查了我的構建路徑，嘗試了不同的Android版本的應用程序，將java合規性級別設置爲1.6（庫也是）等。我只是無法弄清楚問題所在。

這裏是我的清單，我找不到什麼毛病：

你可以發佈MainActivity代碼嗎？ –

您是否正確地在您的地圖項目中引用了Google Play服務庫？這是我的猜測，你不是指gogole play服務庫。第二你應該在清單而不是這個 – Raghunandan

問題是21 - > 22更新我使用timisus的鏈接解決了它。感謝您的幫助 – VorteXavier

嘗試將項目 - >屬性 - > Java構建路徑 - >在線訂單&出口，確保Android的私家藏書被檢查您的項目以及您正在使用的所有其他圖書館項目。
