In the above screenshot, as we can see “AppCompatActivity” is not imported, why is this dependency not being imported. I have good internet connection. Still i am getting the error.

Solved the problem by upgrading android studio to latest version 4.0.0. Deleted the previous project and created a new FirstApp project which automatically took latest dependencies from androidx and etc… Now AppCompatActivity is imported from different package from androidx.
