Android Question Absolutely First compilation fails

Hi,

brand new installation under Win 10.
Everything mentioned in the manual was installed.
AVD manager, paths, Emulator1, and so on

First compilation of the example fails:

AndroidManifest.xml:16: error: Error: No resource found that matches the given name
(at 'theme' with value '@android:style/Theme.Holo').

Normally I don't believe that sayings: but I really did nothing on my own
I already struggle at my first guided babystep...

Whats going wrong?

Thanks
Chris
