progress bar shows when no data connection

When there's no data connection, the progress bar shows endlessly instead of alerting the user to the problem.

When it has no data and no ability to get data, it should display a message instead of the progress indicator. I'd recommend some message like, "You need a data connection to load this content. Please try again with data enabled."

It may be nice to have the widget listen to the network state in order to trigger a refresh once the data connection is established, but that's not necessary and may be confusing when it comes to abstraction layers.

actually the widget is a view object, i think it would not be correct to add there some logic that listens to the network state. These listeners should be added to the activities that then request a view update to the widget. Do you agree?

Yeah, that's a good point.

So the widget plus some adapter that listens to the network state conveniently?

Yes i guess this is the best solution.
