Public Constructors
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. |
Public Methods
public boolean equals (Object obj)
public String getPackageName ()
Returns the name for a package.
public byte[] getSha256Certificate ()
Returns the SHA-256 certificate for a package.
