NavigationDrawer無法安裝應用程序java.lang.classnotfoundexception

我正在開發一個應用程序。在這一部分，我只爲我的導航抽屜進行一項活動。NavigationDrawer無法安裝應用程序java.lang.classnotfoundexception

我m trying to run but I get the same Exception everytime.. I已經搜索了一段時間，嘗試了很多東西，但沒有工作。

Here`s我的logcat：

你使用的是android studio還是Eclipse？ – Droidekas 2015-02-23 21:23:51

這是在模擬器上？ – Droidekas 2015-02-23 21:24:44

我使用Eclipse ..不，它不在模擬器上..我試圖在我的手機上運行.. – 2015-02-24 11:51:36

伊夫已經固定它。我嘗試了很多在Eclipse上不起作用的東西。比我試圖在Android Studio上做到這一點..它的工作！不過感謝您的幫助！
