tipandroid: 10.2.60 之前的版本不支持 本地用户文件。
-
tipandroid: 预览 pdf 时，页面中的链接当前不能跳转，可通过下载文件到本地预览时跳转。
-
tipios: 10.2.60 之前的版本不支持 本地缓存文件。
-
tipios: 10.2.80 之前版本预览文件，路径 filepath 的文件名需要带正确的扩展名，否则会打开失败。如：通过 my.downloadfile 下载 pdf ，获取的本地临时文件在预览时，可能因为文件后缀与文件头信息不对应而打开失败，可通过调用 filesystemmanager.savefile，传入后缀 为 pdf 的 filepath，再预览文件。可使用 my.detectfiletype 判断文件扩展名。
