The shared preferences is for all components associated with the same package (and possibly task/affinity). The key you give it is just a key for a map lookup. The permissions have to do with if the information can be shared or changed with other components in the package. Also, I think you need to still save those preferences either to a file or the database if you want them to remain after the process containing all the components close. From your description I do not think the shared preference behavior is what you want? A quick and dirty way, if you have this in your control, is to change all the uid's for your applications to the same and use the file api's for reading and writing from a file or the database. Using a database is just a step away from using a content provider though... which is probably the correct most solution.
