thanks for the response. (btw it used to work the other way round. did something change in r2 or r3?)
i don't want to do it this way, trust me. i'm having to do this because i can't get a FileDescriptor to a file in /assets in my apk - i get a "this file is zipped" error or somesuch. so i get an InputStream from assetManager.open(path), cache it in /sdcard, then get a FileDescriptor to the file and return that (from ContentProvider.getFile()). is there a better way round this than getting the resources for a "foreign" activity like i'm doing? thanks, j >Those are different component names.
