Toady, I found my AS xml design not worked. It doesn't show anything enter image description here
And this project can build successfully, install apk also successfully, gradle sync,clean porject and rebuild project also successfully too. But the design widow doesn't show anything, I have tried change theme in style.xml, change theme in AS settings, uninstall AS, reinstanll AS(3.6.3, 2020.3.1Fox, 2021.3.1), but not resolve this problem。I've tried everything I can think of。 And i found a difference on AS 3.6.3， on this idea, the project also can run, gradle sync successfully, but design window always show “waiting for build finish”， but this project already build successfully。 enter image description here
Can anyone help me? Thank you very munch。
