Question

我有Facebook登录它工作正常，但有些我如何得到一些用户的以下崩溃。我不是要求任何额外的权限：

Fatal Exception: java.lang.NullPointerException: Attempt to invoke interface method 'java.lang.Object com.facebook.inject.Lazy.get()' on a null object reference

我的代码

 LoginManager.getInstance().registerCallback(callbackManager,
            new FacebookCallback<LoginResult>() {
                @Override
                public void onSuccess(final LoginResult loginResult) {
                     Bundle parameters = new Bundle();
    parameters.putString("fields", "id,name,email");
    GraphRequest request = GraphRequest.newMeRequest(
            loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject me, GraphResponse response) {

            });

    request.setParameters(parameters);
    request.executeAsync();



                }

                @Override
                public void onCancel() {

                }

                @Override
                public void onError(FacebookException exception) {

                }
            });

为什么这个错误不会一直到来，如果我们在android中使用porductflaovers，我们有任何额外的步骤

Facebook NPE java.lang.Object com.facebook.inject.Lazy.get（）
