尝试在最新的 Play-Services v11.0.1 中使用SafetyNetClient.attest(...)进行证明时，客户端出错并返回 ApiException。

代码片段：

byte[] nonce = getRequestNonce();
String apiKey = "<api key>";
mSafetyNetClient.attest(nonce, apiKey)
        .addOnCompleteListener(new OnCompleteListener<SafetyNetApi.AttestationResponse>() {
            @Override
            public void onComplete(@NonNull Task<SafetyNetApi.AttestationResponse> task) {
            ...
            }
        });
...
private byte[] getRequestNonce() {
    String nonceData = "Safety Net Sample: " + System.currentTimeMillis();
    ByteArrayOutputStream byteStream = new ByteArrayOutputStream();
    byte[] bytes = new byte[24];
    mRandom.nextBytes(bytes);
    try {
        byteStream.write(bytes);
        byteStream.write(nonceData.getBytes());
    } catch (IOException e) {
        return null;
    }

    return byteStream.toByteArray();
}

日志输出：

我在这里想念什么？
