I downloaded the Chapter03code.zip and extracted Fragments project, but when I try to import it in Androi Studio I get the error message:" Gradle 'Fragments' project refresh failed
Error:failed to find target with hash string 'android-N' in: C:\Aldo\Android SDK
<a href="install.android.platform">Install missing platform(s) and sync project</a>"

android-N does not exist nowadays.

What should I change in order to have the project imported?
