看起来是设备问题.如果您安装了一些自定义 rom，那么您可能会遇到这个问题.问题跟踪器的链接 https://issuetracker.google.com/issues/159432618>

I am on Android studio 4.1 beta 1 . I installed my app on my device and opened Database Inspector and nothing shows up . Am I supposed to do anything else ?

I am using room database . I can see the database on device . Why is the database not showing up in database inspector?

Looks like its problem with device . If you have some custom rom installed then you might run into this issue . Link to the issue tracker https://issuetracker.google.com/issues/159432618
