我有一個測試項目，它使用OI FileManager。我將該項目作爲Android庫添加到我的測試項目中，然後在庫中調用Activitity。它顯示錯誤：ActivityNotFoundException當包括Android庫
E/AndroidRuntime(1359): FATAL EXCEPTION: main

當我在Manifest中添加該活動的完整路徑時，它會生成另一個錯誤。
<activity
android:label="@string/app_name"
android:name="org.openintents.filemanager.FileManagerActivity" >
</activity>
它顯示：

我會說這是Eclipse中的一個bug。 Eclipse和ADT最近在構建過程中有許多錯誤：ClassNotFound和ActivityNotFound。
更新： 我的代碼只需使用一條線路：
final Intent intent = new Intent(FileExplorerTest.this, FileManagerActivity.class);
startActivity(intent);
其實我有3個項目。 2個圖書館項目和1個測試項目。庫「OI文件管理器」使用庫「OI分佈」，然後測試項目C使用庫「IO文件管理器」。
清潔項目。 – 2012-07-25 07:51:24
顯示如何開始活動。當項目被添加爲Android庫時，您不需要在清單中添加活動標籤。 – pawelzieba 2012-07-25 07:51:58
你試過android：name =「。filemanager.FileManagerActivity」或者android：name =「。org.openintents.filemanager.FileManagerActivity」這個點（。） – 2012-07-25 07:53:31
