The only time you need to implement openAssetFile() is when you have files that you want the user of ContentProvider to open. For example, if you were writing a picture ContentProvider, you may pass description information in response to a query along with a URL that can be used for ContentResolver.openAssetFileDescriptor (or ContentResolver.openInputStream which calls it).
However, if you just need to pass a blob of decrypted data, you can pass that as a blob in one of the Cursor columns. No need for it to hit the filesystem at all.
