public class AccessibilityDetector
extends com.android.tools.lint.detector.api.LayoutDetector

Check which looks for accessibility problems like missing content descriptions

TODO: Resolve styles and don't warn where styles are defining the content description (though this seems unusual; content descriptions are not typically generic enough to put in styles)
