Safetynet 问题状态{statusCode=NETWORK_ERROR, resolution=null}

Question

虽然我们的 android 设备提供 4G 互联网连接，但我们正面临“Status{statusCode=NETWORK_ERROR, resolution=null}”事件错误使用包名 com.safetynet.sample，其中示例项目使用包名 com.scottyab.safetynet.sample 运行良好。我们检查了但没有工作。

下面是我们遇到这个问题的代码

private void runSafetyNetTest() {
    Log.v(TAG, "running SafetyNet.API Test");
    requestNonce = generateOneTimeRequestNonce();
    requestTimestamp = System.currentTimeMillis();
    writeLog("running SafetyNet.API Test");
    SafetyNet.SafetyNetApi.attest(googleApiClient, requestNonce)
            .setResultCallback(new ResultCallback<SafetyNetApi.AttestationResult>() {
                                   @Override
                                   public void onResult(final SafetyNetApi.AttestationResult result) {
                                       writeLog("running SafetyNet.API Result");
                                   //result = Status{statusCode=NETWORK_ERROR, resolution=null} 
                                       if (!validateResultStatus(result)) {
                                           return;
                                       }

                                       final String jwsResult = result.getJwsResult();
                                       final SafetyNetResponse response = parseJsonWebSignature(jwsResult);
                                       lastResponse = response;
                                       writeLog("Res :: " + response);

                                       //validate payload of the response
                                       if (validateSafetyNetResponsePayload(response)) {
                                           if (!TextUtils.isEmpty(googleDeviceVerificationApiKey)) {
                                               //if the api key is set, run the AndroidDeviceVerifier
                                               AndroidDeviceVerifier androidDeviceVerifier = new AndroidDeviceVerifier(googleDeviceVerificationApiKey, jwsResult);
                                               androidDeviceVerifier.verify(new AndroidDeviceVerifier.AndroidDeviceVerifierCallback() {
                                                   @Override

                                                   }

                                                   @Override

Answer 1

这可能与证明 API 已被标记为已弃用这一事实有关。新的不依赖google客户端API，你应该检查this. Also Google released an example app using the new api, you can check here。

Answer 2

按照this discussion，错误的API_KEY可能是错误的原因。
