How can we grantPermission on Iroha with iOS code to android

[Engineering12345]

I have sample code from ios and don't know how to write this code to andion :

       func grantPermission(publicKey :String,priKey:String, transaction: IRTransaction, 
                reducedRecoveryHash: 
                Data, reducedAdminGrantHash: Data) throws -> IRTransaction  {
                let publicKeyData = NSData(hexString: publicKey)! as Data
                let publicKey = IREd25519PublicKey(rawData: publicKeyData)!
       
                let privateKeyData = NSData(hexString: priKey)! as Data
                let privateKey = IREd25519PrivateKey(rawData: privateKeyData)!
                let signer = IREd25519Sha512Signer(privateKey: privateKey)!
        
                let reducedHash = try transaction.batchHash()
                let tx = try transaction
                            .batched([reducedHash, reducedRecoveryHash, reducedAdminGrantHash], batchType: .atomic)
                           .signed(withSignatories: [signer], signatoryPublicKeys: [publicKey])
       
        return tx
 
    
}
