Apps Unable to instantiate activity ComponentInfo for Facebook SDK Samples

[nfoboy]

So I am trying to learn how to use Facebook's SDK, so I went to their website, and thought I would try out some of their sample tutorials.

I have been stuck, and killed practically an entire day due to the fact that I can't figure out why their samples won't work!

Every time I try to run a Facebook from Eclipse, I get this:

and here's the manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.facebook.samples.profilepicture"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="8"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application android:label="@string/app_name"
android:icon="@drawable/icon" >
<activity
android:name=".ProfilePictureSampleActivity"
android:label="@string/app_name"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

I have even gone so far to download and do a complete new install of the ADT, grab the SDK's for development, and then import the files to the new install, and I am getting the exact same errors.

All of my previous programs are compiling just fine, so I am at a complete loss on what to do.

Has anyone here been successful in trying out the Facebook examples?
