Unity build error: No resource found that matches the given name 'android:Theme.Holo.Light.NoActionBar.Fullscreen'

Question

I'm building a Unity project and when I'm trying to build the project for android, I get this error:

error: Error retrieving parent for item: No resource found that matches the given name 'android:Theme.Holo.Light.NoActionBar.Fullscreen'.

I know these kinda errors can be fixed when creating an android project using Android Studio by modifying manifest file or something like that. But how can I fix such errors in Unity?

Here's the full error:

This is possibly a bug in Unity. I know this is a bit late, but in case someone else runs into the same problem. This is work-around of how I got rid of the error:

1. In the Unity Editor click Edit -> Project Settings -> Player
2. In the Inspector click on Android Settings (Android icon)
3. In the Player Settings panel top right corner you will find a very small gear icon. Click on it and select the "Reset" pop up menu.

This will reset your player settings back to the defaults that should compile at least. For me this took the error away.

Once the project is compiling again, you can manually re-apply your settings one by one in the Player Settings panel until you find the culprit setting cause the issue and file a bug report at Unity.
