< Jeremy> thanks for replying I clicked clean amp amp rebuild project clicked invalidate caches deleted the app and install it again in my phone removed some annotations but there is no result the app works again Even the app works when I use wrong annotations thinking face I use Hilt DI with Java with only this dependency implementation com google dagger hilt android 2 37

Jeremy · Answer

Looks like your xml is specifying the fragment which is resulting in `Caused by java lang ClassNotFoundException com example News view fragments HomeFragment`

Jeremy · Answer

You should avoid the `fragment` tag and setup fragments in code
