public PackageIdentifier (String packageName, byte[] sha256Certificate)

Creates a unique identifier for a package.

SHA-256 certificate digests for a signed application can be retrieved with the apksigner tool that is part of the Android SDK build tools. Use apksigner verify --print-certs path/to/apk.apk to retrieve the SHA-256 certificate digest for the target application. Once retrieved, the SHA-256 certificate digest should be converted to a byte[] by decoding it in base16:

 new android.content.pm.Signature(outputDigest).toByteArray();
Parameters
packageName Name of the package.
sha256Certificate SHA-256 certificate digest of the package.
