Eclipse Android

Hi, I’m not certain that I’m in the correct place so really humble apologies if that’s not wtight (but I’m getting desperate )….

I am trying to start some Android code for app (after many years coding), and I have install Eclipse and the Android SDK.

I have done a fresh install of Eclipse on Windows 10 and have created (what I think) is a vanilla project.
I try to open the project and nothing happens. I look at the console log:
Error retrieving parent for item: No resource found that matches the given name 'Theme.AppCompat.Light'.*
And I get some errors like:

“…Check the console for output.” And various other errors.

I can provide the rest of the errors if needed.

Any ideas please?
Many thanks.
