I wanted a file explorer in my application hence while googling I found “Android File Dialog” on code.google.com. The output from the source is a android library which I have included in my Android Project as “Required Project on the Build Path” in project properties dialog. But when I run my application it is giving me exception-

java.lang.NoClassDefFoundError: com.lamerman.FileDialog

The line where the error occurs is-

Intent intent = new Intent(this, FileDialog.class);

This line is in the Activity onCreate method.

I have even added following entry in the AndroidManifest.xml–

<activity android:name="com.lamerman.FileDialog" />

I am not getting any compilation error in Eclipse.

Am I missing some thing while running the application using a Library?
