Android resources in library not inherited by library consumer when running in Android1.5

I have a common library I use for apps of a similar type. The library has png files in the res/drawable-hdpi folder, as they are used by in all the other apps that use the library, so I don't have to keep copies in each application.

It seems that in Android 1.5, the drawable resources from the library are NOT inherited when the application imports the library, but does in all versions beyond Android 1.5. My application runs, and I immediately get a ResourceNotFoundException when an activity that uses the resource is loaded. Is there a way I can specify the resources as public or available in some way? I specified Activities in the library within the Android Manifest so they could be run by users of the library. Is there a way to do that with resources? Also, why is this only happening with Androi 1.5? Thanks?

Those folders like 'res/drawable-hdpi' where introduced first in Android 1.6. Android 1.5 only supports the 'res/drawable'-folder.
