These have been really irritating. Here are the errors I am getting. I am on windows 10.

Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'.


Error:(2) Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Button.Colored'.

Error:Execution failed for task ':app:processDebugResources'.

> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Users\John\AppData\Local\Android\sdk1\build-tools\23.0.0\aapt.exe'' finished with non-zero exit value 1


I believe these are also stopping me from being able to run the AVD. 

Thank you for taking the time to help me.
