js版 [即时通信] sdk，使用 CocosCreator 开发，web上可以，【打包Android】后不可以

【求助，非常感谢】

js版 [即时通信] sdk

开发使用的游戏引擎：Cocos Creator

问题描述：

在 web 平台上，已经调通了所有功能，Creator 打包 Android，在 Android 平台上，调用 createIMClient 接口，不成功。

===========

相关代码：

    cc.log("M_IM 开始连接");
    // 使用自己的id登陆
    realtime.createIMClient(this._app.playerData.id).then(function(client)
    {
        cc.log("M_IM 登陆成功!");

    }).catch((error) =>
    {
        // 连接失败
        cc.log("M_IM 登陆失败!");
        console.error(error);
    });

==============

运行log：
