facebook登录服务未注册

Question

当我在我们的应用程序中使用Facebook登录时，我遇到了问题。有时我签名，它会因此错误而崩溃。我搜索了类似的排名，但不太了解。

java.lang.IllegalArgumentException:Service not registered: com.facebook.login.GetTokenClient@1ab2a49b

这是我的代码：initLogin()方法中的onCreate()

 private void initLogin() {
    callbackManager = CallbackManager.Factory.create();
    LoginManager.getInstance().registerCallback(callbackManager,
            new FacebookCallback<LoginResult>() {
                @Override
                public void onSuccess(final LoginResult loginResult) {
                  String mToken = loginResult.getAccessToken().getToken();
                  if(!TextUtils.isEmpty(mToken)){
                    GraphRequest graphRequest = GraphRequest.newMeRequest(AccessToken.getCurrentAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                            @Override
                            public void onCompleted(JSONObject object, GraphResponse response) {
                           if (response.getError() != null) {
                                Log.d(TAG, "FB: parse info error!");
                                onLoginFail(Constants.LOGIN_FACEBOOK);
                            } else {
                                LogHelper.d(TAG, "Object:" + object.toString() + ",Response:" + response);
                                loginPresenter.startLoginFacebook( loginResult.getAccessToken().getToken(),
                                object.optString("id"), object.optString("name"),
                                object.optString("picture"), object.optString("email"));
                           }
                        }

                    });
                    Bundle mParameters = new Bundle();
                    mParameters.putString("fields", "id,name,email,gender,picture,birthday");
                    graphRequest.setParameters(mParameters);
                    graphRequest.executeAsync();
                 }else {
                     onfailed();
                 }

             }

            @Override
            public void onCancel() {
                LogHelper.d(TAG,"User cancel to login FB。");
            }

             @Override
             public void onError(FacebookException exception) {
                onfailed();
            }

                private void onfailed() {
                   ToastUtil.showToast(getApplicationContext(), R.string.footer_net_error);
               }

});

我发现Facebook类PlatformServiceClient在这里有一个null结果：

protected abstract void populateRequestBundle(Bundle data);

protected void handleMessage(Message message) {
    if (message.what == replyMessage) {
        Bundle extras = message.getData();
        String errorType = extras.getString(NativeProtocol.STATUS_ERROR_TYPE);
        if (errorType != null) {
            callback(null);
        } else {
            callback(extras);
        }
        context.unbindService(this);
    }
}

额外内容为空。

有人可以帮助我吗？谢谢。
