Can't cast this into Executor in google reCAPTCHA

Question

I have a problem with google recaptcha. I'm using theirs example from https://developer.android.com/training/safetynet/recaptcha#java but I get error when I try casting this into Executor.

Error which I get is: com.johny.Aktivity.Activity cannot be cast to java.util.concurrent.Executor.

I tried impementing Executor but then Android Studio forces me to include execute(Runnable) and recapcha always ends up there and not in the onSuccess() or onFailure().

Actually, I'm not sure that why the code shown at android developer site is not working, but you can try below code in which I have just used different methods for success and failure listeners.

 SafetyNet.getClient(this).verifyWithRecaptcha("YOUR_API_SITE_KEY")
            .addOnSuccessListener(new OnSuccessListener<SafetyNetApi.RecaptchaTokenResponse>() {
                @Override
                public void onSuccess(SafetyNetApi.RecaptchaTokenResponse recaptchaTokenResponse) {
                    // Indicates communication with reCAPTCHA service was
                    // successful.
                    String userResponseToken = recaptchaTokenResponse.getTokenResult();
                    if (!userResponseToken.isEmpty()) {
                        // Validate the user response token using the
                        // reCAPTCHA siteverify API.
                        Log.e(TAG, "VALIDATION STEP NEEDED");
                    }
                }
            })
            .addOnFailureListener(new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    if (e instanceof ApiException) {
                        // An error occurred when communicating with the
                        // reCAPTCHA service. Refer to the status code to
                        // handle the error appropriately.
                        ApiException apiException = (ApiException) e;
                        int statusCode = apiException.getStatusCode();
                        Log.e(TAG, "Error: " + CommonStatusCodes
                                .getStatusCodeString(statusCode));
                    } else {
                        // A different, unknown type of error occurred.
                        Log.e(TAG, "Error: " + e.getMessage());
                    }
                }
            });
