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
