I have been seeing several posts about this App Theme problem.
The good news is you can still continue the tutorials. Just don't change the theme.

Some things to note:
1. When Bucky create tutorial # 4 He was not using Version 23.
Android is constantly evolving and things become depreciated.
2. Are you trying to follow and old example that changes the type of Activity?.
#4  is using ActionBarActivity but you may be using AppCompatActivity
3. Is your min API using features not supported by Material?
#3 suggest using API 8. There are a lot of features not going to be on hardware that old.
I suggest using a min of API16 with V23.

Here are some places to look at for clues.
1. What is your min API?
2. What is your activity.?
Try - public class MainActivity extends AppCompatActivity {
and
import android.support.v7.app.AppCompatActivity;
3.Check your style
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>

Let me know if this helps or if you figure out the problem.
P.S.
I am not sure if you are missing a library during the installation process. This is rare but It happened to me with V23.
If the above didn't work i will show you my SDK manager. in a reply.
