The user agent does not support public key credentials.

[yuejunfei]

Hello, I use Web3Auth to access the Android example, and open https://sdk.openlogin.com/login# with the browser of the Android system. It prompts me that The user agent does not support public key credentials. How can I solve this error?

Hey @yuejunfei

Could you share which example you are using? Or the code snippet of your android app?

And please share the error(screenshot) by going to the chrome://inspect tool.

`class MainActivity : AppCompatActivity() {

private lateinit var web3Auth: Web3Auth

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    web3Auth = Web3Auth(
        Web3AuthOptions(
            context = this,
            clientId = getString(R.string.web3auth_project_id),
            network = Web3Auth.Network.TESTNET,
            redirectUrl = Uri.parse("art.mints.myapplication://auth"),
            whiteLabel = WhiteLabelData(  // Optional param
                "Web3Auth Sample App", null, null, "en", true,
                hashMapOf(
                    "primary" to "#123456"
                )
            )
        )
    )


    web3Auth.setResultUrl(intent?.data)


    // Calls sessionResponse() to check for any existing session.
    val sessionResponse: java8.util.concurrent.CompletableFuture<Web3AuthResponse> =
        web3Auth.sessionResponse()

            Log.d("MainActivity_Web3Auth", error.message ?: "Something went wrong")
            // Ideally, you should initiate the login function here.
        }
    }

    // Setup UI and event handlers
    val signInButton = findViewById<TextView>(R.id.signInButton)
    signInButton.setOnClickListener { signIn() }

}

override fun onNewIntent(intent: Intent?) {

        }
    }
}
