Ah okay, the thing to remember here is that the full, complete name of your class includes the package name. So check out the error statement: it refers to "com.teamtreehouse.ribbit.BlogWebViewActivity:

android.content.ActivityNotFoundException: Unable to find explicit activity class {com.teamtreehouse.ribbit/com.teamtreehouse.ribbit.BlogWebViewActivity

But in your manifest, you have:

android:name="com.neils.blogreader.BlogWebViewActivity"

Which package name matches how you have it declared in your BlogWebViewActivity.java file? I'm guessing the one with your own name. You'll need to fix the import statement in your NewsFragment to import the correct one, and then this error should go away.
