那些遇到过的问题

解析失败：Lcom/amazonaws/mobileconnectors/cognitoauth/handlers/AuthHandler；

c0d*_*d3r 4 android aws-sdk google-signin aws-amplify

我配置了 Google 登录和 AWS 身份池。我正在尝试在没有 AWS 登录 UI 的情况下设置google 登录。使用 google 成功登录后，我尝试在 android 中访问 AWSMobileClient API，但我无法访问此 API 我不知道我的代码中有什么问题。有一个异常导致我的应用程序崩溃。

我的代码在这里

AWSMobileClient.getInstance().federatedSignIn(IdentityProvider.GOOGLE.toString(), googleSignInAccount.getIdToken(), new Callback<UserStateDetails>() {
        @Override
        public void onResult(UserStateDetails result) {
            showToast("sigin in success");
        }

        @Override
        public void onError(Exception e) {
            e.printStackTrace();

        }
    });
