Android Question Android keystore: Get Public Key from Java Object?

[KMatle]

I use this code to access a certificate in Android's keystore:

Dim keystore As JavaObject
    keystore = keystore.InitializeStatic("java.security.KeyStore").RunMethod("getInstance", Array("AndroidKeyStore"))
    keystore.RunMethod("load", Array(Null))
    Dim entry As JavaObject = keystore.RunMethod("getEntry", Array(alias, Null))
    Dim PrivateKey As JavaObject = entry.RunMethod("getPrivateKey", Null)
    Dim PublicKey As JavaObject = keystore.RunMethodJO("getCertificate", Array(alias)).RunMethod("getPublicKey", Null)

which works fine. Accessing the PublicKey I get "(AndroidKeyStoreRSAPublicKey) android.security.keystore.AndroidKeyStoreRSAPublicKey@9bf04cbe".

How do I get the real value?
