消息发送失败:201---User has not login.

环信3.0,我集成了EaseUI,可以成功登录并执行了登录成功的回调.

        EMClient.getInstance().login(userName, pwd, new EMCallBack() {

            @Override

            public void onSuccess() {

                EMClient.getInstance().groupManager().loadAllGroups();

                EMClient.getInstance().chatManager().loadAllConversations();

                Log.v("环信登录成功","!!!!!!!!!!!");

            }



            @Override

            public void onError(int i, String s) {





            }



            @Override

            public void onProgress(int i, String s) {

                Log.e("环信聊天", "登录聊天服务器失败");

            }

        });

登录到聊天界面后我发送了文本消息,接着就提示我User has not login.
然后我在发送处加了判断当前用户是否登录
 

  protected void sendMessage(EMMessage message){

        if(!EMClient.getInstance().isLoggedInBefore()) {

            Log.v("你并没有登录","!!!!!!!!!!!!!!!!!");

        }

        if (message == null) {

            return;

        }

        if(chatFragmentListener != null){

            //设置扩展属性

            chatFragmentListener.onSetMessageAttributes(message);

        }

        // 如果是群聊，设置chattype,默认是单聊

        if (chatType == EaseConstant.CHATTYPE_GROUP){

            message.setChatType(ChatType.GroupChat);

        }else if(chatType == EaseConstant.CHATTYPE_CHATROOM){

            message.setChatType(ChatType.ChatRoom);

        }

        //发送消息

        EMClient.getInstance().chatManager().sendMessage(message);

        message.setMessageStatusCallback(new EMCallBack() {

            @Override

            public void onSuccess() {

                Log.v("====成功发送了消息====","====成功发送了消息====");

            }



            @Override

            public void onError(int i, String s) {

                Log.v("====消息发送失败原因=====","code=="+i+"====desc==="+s);

            }



            @Override

            public void onProgress(int i, String s) {



            }

        });

        //刷新ui

        if(isMessageListInited) {

            messageList.refreshSelectLast();

        }

    }

Log.v("你并没有登录","!!!!!!!!!!!!!!!!!");
并没有打印,看到社区也有很多类似的问题,但始终没有一个合理的解释
