ReCaptcha V2 response error 12008 in Android

Question

Below is my implementation of ReCaptcha V2 in my Android app. When I run it, it returns: Error message: unknown status code: 12008

This means the following:

public static final int RECAPTCHA_INVALID_KEYTYPE Cannot start the reCAPTCHA service because type of site key is not valid.

Please register new site key with the key type set to "reCAPTCHA Android" via //g.co/recaptcha/androidsignup.

Constant Value: 12008

My site key is available on my ReCaptcha admin portal, so what do I need to do for it to be 'valid'?

The code example that I've implemented does include the following comments regarding the server url:

//it is google recaptcha siteverify server
//you can place your server url

Is this a requirement or a suggestion?

public void onCaptchaClick(View view) {
    SafetyNet.getClient(this).verifyWithRecaptcha(SITE_KEY)
            .addOnSuccessListener(this, new OnSuccessListener<SafetyNetApi.RecaptchaTokenResponse>() {
                @Override
                public void onSuccess(SafetyNetApi.RecaptchaTokenResponse response) {
                    if (!response.getTokenResult().isEmpty()) {
                        handleSiteVerify(response.getTokenResult());
                    }
                }
            })
            .addOnFailureListener(this, new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    if (e instanceof ApiException) {
                        ApiException apiException = (ApiException) e;
                        Log.d(TAG, "Error message: " +
                                CommonStatusCodes.getStatusCodeString(apiException.getStatusCode()));
                    } else {
                        Log.d(TAG, "Unknown type of error: " + e.getMessage());
                    }
                }
            });

}


protected  void handleSiteVerify(final String responseToken){
    //it is google recaptcha siteverify server
    //you can place your server url
    String url = "https://www.google.com/recaptcha/api/siteverify";
    StringRequest request = new StringRequest(Request.Method.POST, url,

            return params;

    };
    request.setRetryPolicy(new DefaultRetryPolicy(

This error means that you are not using the right key.

Have you created an Android app key or a website key? I got this error when I tried to use the web key for the app, you need an Android app key.
