Getting started with Android Studio

[WinchestStoke]

Hi, I am trying to use Android Studio (3.1.3) for the first time and I’m hitting a problem very early on.

On starting the project I am using pretty much vanilla settings, but when I try to put a Button I get the following errors:

“Failed to load AppCompat ActionBar with unknown error.”

And…

“This view is not constrained….”

Any help on getting me started would be really appreciated. Thanks.

Don't use ConstraintLayout. It's too complicated for beginners.
Use LinearLayout.

For “This view is not constrained….” error:

Make sure you click the "Infer Constraints" button once you done adjusting the layout.
