I’m in chapter 1, page 8, and Android Studio has just created and opened my new project. All seemed to be going well, but in the lower pane of the screen of my Project Window there are a series of ominous messages:
Failed to find target with hash string ‘android-26’ in: C:\Users\cwldo\AppData\Local\Android\Sdk
Consult IDE log for more details (Help | Show Log)
Install missing platform(s) and sync project
What does it mean and what should I do? I am just beginning my study of Android Programming.
