The new Android Studio update came out sometime last week (January 2019 Version 3.3). In the previous version you'd be able to create new project and click a checkbox that said "add a fragment". Unfortunately, in the new update I can't find this checkbox or anything related.
Do we now have to add fragments by hand? Or is there a way to create a project with a fragment?
I found the solution. Before Version 3.3 you were able to create a new project and set the basic activity as a fragment. Since Version 3.3 update it no longer gives you the option to create a fragment when creating a new project.
So this is how you're supposed to do it:
Create a new project with whatever activities you want.
Switch to Android View -> Right click on "app" under the navigator -> New -> Activity -> Basic Activity Now a separate window will open up and you're able to select the checkbox "Use a fragment".
