我不明白你的代码没有写请求权限的代码，我仿着写了一个结果会有这个错误

在您的demo中targetSdkVersion和compileSdkVersion>=29就无法正常显示，包括动态获取权限

你应该先申请读取权限，看报错信息是没有权限读取 pdf 文件

beilvla · 2021-11-07T07:49:43Z

我加入了获取权限的代码还是提示这个问题，是在targetsdkVersion和complieSdkVersion>=29时

但是看报错日志是没有权限读取，你试一下在“设置”中授权读取文件权限呢？

beilvla · 2021-11-08T01:08:51Z

都开启了，还是不行😂😂😂，包括后台手动设置中开启在是在targetsdkVersion和complieSdkVersion>=29时就是不行

NanoMichael · 2021-11-08T10:03:20Z

只是在 demo 中改了 targetSdkVersion 和 complieSdkVersion 吗？你所要读取的文件是否存在呢？

beilvla · 2021-11-08T10:11:37Z

只是在 demo 中改了 targetSdkVersion 和 complieSdkVersion 吗？你所要读取的文件是否存在呢？

当然存在，本来想自己防着你的demo写一个结果不行，然后把这两个将为29以下即可，包括你的demo也是>=29也是会有这个问题（动态获取权限）

NanoMichael · 2021-11-08T11:13:23Z

OK，我一会看下是什么问题

大佬找到什么问题了吗？

sorry，我前天没有复现问题，这两天工作比较忙，我今晚再看下
