The passive location provider will provide you with location data when other apps that have requested location updates get their data. So if no other app on the phone is getting location updates, you won't get them either.

If you want to see the last value that each provider has obtained in the past then you must use getLastKnownLocation with the network or gps provider.

For comprehensive details on getting location updates see this:

In that article, look at the section called "Freshness means always being up to date. What if we could reduce startup latency to zero?". See the linked code for Froyo+ passive location updates.
