[android-developers] RemoteViewsService can't access ContentProvider in same app

I'm stepping through "Professional Android 4 Application
Development". I'm attempting to enter most of the code samples by
hand, but I'm deploying the provided downloaded apps if what I've
entered doesn't match what I expect.

I'm on chapter 14, the 3rd iteration of the "Earthquake" example,
which adds a list widget. The regular widget works fine, but when I
try to place the list widget on the homescreen, I get the following:

FATAL EXCEPTION: Binder Thread #2
java.lang.SecurityException: Permission Denial: reading
com.example.earthquake.EarthquakeProvider uri
content://com.example.earthquakeprovider/earthquakes from pid=806,
uid=10001 requires null
at android.content.ContentProvider
$Transport.enforceReadPermission(ContentProvider.java:295)
at android.content.ContentProvider
$Transport.query(ContentProvider.java:177)

When I install the corresponding app version from the code download,
it works fine. I must be missing a small detail, but I don't see it.
I've carefully compared the differences between the manifest files,
but I don't see anything that's obviously relevant.

If it matters, here is my entire app manifest. The only permission
entry relevant to the list widget is "BIND_REMOTEVIEWS", but the code
sample has the same thing.
