Android Studio-无法在虚拟设备上运行应用程序

Question

i am total newbie into android studio and java. Could you give me some advice how to fix these errors? I am using older android studio because of the tutorials I am following, the guy has this version so to keep it as simple as it can get, I am trying to stay on the same version (1.0.0)

EDIT: I am unable to post pictures, so I will just paste the error code lines here.

Gradle

Error:(1) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Borderless.Colored'.

My configuration:

Compile Sdk Version: API 21: Android 5.0 (Lollipop)
Build tools version: 21.1.2

Virtual device

I was unable to create the virtual device, because I was unable to proceed to the "creation" screen, due to mentioned errors.

Answer 1

Updating Android studio fixed the problem and didn't bring up any errors while following tutorial of older version android studio.

Thanks for all the help.
