我有一个测试项目，它使用OI FileManager。我将该项目作为Android库添加到我的测试项目中，然后在库中调用Activitity。它显示错误：ActivityNotFoundException当包括Android库
E/AndroidRuntime(1359): FATAL EXCEPTION: main

当我在Manifest中添加该活动的完整路径时，它会生成另一个错误。
<activity
android:label="@string/app_name"
android:name="org.openintents.filemanager.FileManagerActivity" >
</activity>
它显示：

我会说这是Eclipse中的一个bug。 Eclipse和ADT最近在构建过程中有许多错误：ClassNotFound和ActivityNotFound。
更新： 我的代码只需使用一条线路：
final Intent intent = new Intent(FileExplorerTest.this, FileManagerActivity.class);
startActivity(intent);
其实我有3个项目。 2个图书馆项目和1个测试项目。库“OI文件管理器”使用库“OI分布”，然后测试项目C使用库“IO文件管理器”。
清洁项目。 – 2012-07-25 07:51:24
显示如何开始活动。当项目被添加为Android库时，您不需要在清单中添加活动标签。 – pawelzieba 2012-07-25 07:51:58
你试过android：name =“。filemanager.FileManagerActivity”或者android：name =“。org.openintents.filemanager.FileManagerActivity”这个点（。） – 2012-07-25 07:53:31
