Question

cannot verify signature

Why do I verify the data returned after Google payment that does not go through the grid successfully, and it always fails to verify the signature, so how to check or solve it?

String decryptedMessage =
new PaymentMethodTokenRecipient.Builder()
.fetchSenderVerifyingKeysWith(
GooglePaymentsPublicKeysManager.INSTANCE_TEST
)
.recipientId("GooglePayPasses")
.protocolVersion("ECv2")
.addRecipientPrivateKey("MIGHAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBG0waXXXXXX")
.build()
.unseal(tokenData);
