腾讯TBS浏览服务打开本地文档(word.pdf.ppt)踩过的坑

记录一下安卓使用腾讯tbs浏览本地文档(word.pdf.ppt)踩过的坑，以方便以后自己面查阅跟供他人参考。
腾讯TBS服务官网介绍

遇到的坑：
1、按照文档接入sdk，并在DemoApplication 初始化加载tbs内核不成功，（周五、周六、周日）通常是初始化加载不成功，其他时间段没问题

2、tbs初始化加载成功，添加显示具体文档的时候，一直提示 "插件加载失败"

处理办法：
问题1：按照sdk流程初始化初始化加载tbs内核，加载内核不成功重新调用下载方法：

TbsDownloader.startDownload();

10次都加载不成功，直接手动加载安装本地tbs内核资源（本地tbs资源可以放在自己的服务器上）：

QbSdk.installLocalTbsCore()  问题2： 根据官网常见问题做对应的修改即可：
腾讯浏览服务  3.7 targetAPI为Android P时无法下载内核？
