Package formats like apk and jar avoid this chicken and egg problem by hashing the files inside a package, and storing those hashes in a manifest file. Signatures only sign the manifest file. The manifest itself and the signature files are not part of the manifest, but are part of the package. So a package including it's signature(s) is still a single file.
