Error inflating anything from the design support library
xml
In addition to Emmanuel's answer you could be facing the following problem.
It seems like the design library components need a style which is based on an AppCompat Theme. So try to use "Theme.AppCompat.[...]" as a parent in your style.xml.
Example:
Then add the following to your build.gradle as well:
compile 'com.android.support:appcompat-v7:22.2.0'
Additionally you should update the following lines in your gradle as well:
classpath 'com.android.tools.build:gradle:1.2.3'
compileSdkVersion 22
buildToolsVersion '22.0.1'
targetSdkVersion 22
