You might be able to use the android:sharedUserId attribute in your manifest, and set the value identically in all applications that need access to this data. Doing that, if you have one package designated as the primary one (say, com.example.master), and multiple other packages (sa, com.example.slave1, com.example.slave2), you should be able to have all routines access the "files" area within com.example.master since their user ID's will be the same.
This won't make the data invisible on a rooted device, but as long as the device is not rooted, the file access will be limited to your set of applications. Caveats: * Each application must be signed with the same key. * If the application is already installed without a sharedUserId (or with a different sharedUserId), you will not be able to properly update the application. The problem is that /data/data/package.name already exists, with the previous user ID. To update, you need to uninstall the old APK and you may also need to then manually delete the directory -- not an option for an application that's already distributed to user devices.
