Per the documentation the Content Provider authority must be unique and describes nothing about the name needing to be unique.
A Content Provider works fine in a library if it is the only application on the device with the library installed. The behavior I see with multiple apps when pointing the name to a library class is that the query will always hit the Content Provider in a single apk. I see the other Content Providers in the cursor object that comes back, but it only invokes the Content Provider in only a single apk. This is easy to reproduce in Android 2.2 and 2.3.4, I have not tried other versions. A simple workaround I found was to have the applications include an empty class that extends the library Content Provider and point the Content Provider name to this emtpy class. This works fine, however, it is unfortunate that clients calling the library must have this empty class. My guess is there are some namespace issues. Is there some other object within the Context object I can flush/reset? In case your wondering how the library queries the Content Providers, it grabs a list of Content Providers on the device and matches a common prefix on the authority. Then I have a signature matching permission to enforce all communication occurs between applications of the same signature. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
