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

Question

我们有关注Scottyab Safetynet Library .

虽然我们的 Android 设备中包名称为 com.safetynet.sample Status{statusCode=NETWORK_ERROR, resolution=null}”事件错误strong> 作为示例项目，包名称 com.scottyab.safetynet.sample 运行良好。我们有检查this solution但不起作用。

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();

这可能与证明 API 已被标记为已弃用的事实有关。新的不依赖于谷歌客户端 API，你应该检查 this . Google 还发布了一个使用新 API 的示例应用程序，您可以查看 here .
