使用 SafetyNet Attestation API 的安全环境检查 android 无法正常工作，因为它没有在成功或失败回调时获得回调

Question

为了安全环境检查 android 我使用的是

https://developer.android.com/training/safetynet/attestation.html

SafetyNet.getClient(this).attest(nonce, API_KEY)
   .addOnSuccessListener(this,successListner)
   .addOnFailureListener(this,failureListener)

为此我收到失败回调 网络错误 null。任何人都可以对此有所了解吗？

但是https://medium.com/@hargoyal/secure-android-app-with-safetynet-8e367a1c8ad0

SafetyNet.SafetyNetApi.attest(mGoogleApiClient, nonce)
                .setResultCallback(new ResultCallback<SafetyNetApi.AttestationResult>() {
                    @Override
                    public void onResult(SafetyNetApi.AttestationResult result) {
                        Status status = result.getStatus();
                        if (status.isSuccess()) {
                            decodeJws(result.getJwsResult());
                            // Indicates communication with the service was successful.
                            // Use result.getJwsResult() to get the result data.
                        } else {
                            // An error occurred while communicating with the service.
                        }
                    }
                });

此方法有效，但 SafetyNet.SafetyNetApi 已弃用。

重新检查 API 键或创建一个新键，例如 here。我遇到了同样的问题，问题是我将密钥限制为错误的包名称。

• Go to the Library page in the Google APIs Console.
• Search for the Android Device Verification API. When you've found the API, click on it. The Android Device Verification API dashboard screen appears.
• If the API isn't already enabled, click Enable.
• If the Create credentials button appears, click on it to generate an API key. Otherwise, click the All API credentials drop-down list and select the API key that is associated with the project for which the Android Device Verification API is enabled.
• In the sidebar on the left, click Credentials. Copy the API key that appears.
