Screen Shot #1 - Android Studio Project Gradle Build View Screen Shot #2 - Android Studio Project Gradle Sync View Going through the "Android Studio 2.2 Development Essentials book" and following along with the tutorial in chapter 3. Everything was OK until I completed a task in the Development Essentials book (chapter 3, page 24 in book) that said, As we can see from the component tree hierarchy, the user interface layout consists of a layout parent with a single child in the form of a TextView object. If Android Studio has used a RelativeLayout manager for the project, the first step is to convert it to a ConstraintLayout. ConstraintLayout is a new and flexible layout manager that is used in most projects in this book. To achieve this conversion, right-click on the content_android_sample entry in the Component Tree and select the Convert RelativeLayout to ConstraintLayout menu option as shown below: Upon completion of the above quoted tutorial task (in chapt. 3 of the Development Essentials book), an error was presented that said: Error: Failed to resolve: com.android.support.constraint:constraint-layout:1.0.0-alpha1 Also, a rendering error was listed as well that said: Rendering Problems The following classes could not be found: - android.support.constraint.ConstraintLayout ( Add constraint-layout library dependency to the project, Fix Build Path, Edit XML, Create Class) Any thoughts on how to fix this?
