I get the error when clicking on the run button that says cannot compiler and I set it to JDK 1.8 in the SDK part but still get the same error in IntelliJ Ultimate. Any thought how this can be fixed?

Does the project include SDKs for other languages etc.? Android, C/++. Those will need defining too. – Harmelodic Mar 13 '16 at 12:25

You need to check also the Project
tab on that page, and each module's SDK under the Modules
tab and its Dependencies
sub-tab. They all allow you to specify what SDK to use at different levels. The Project
tab should be set to the only SDK you have, but it might not have anything set and similarly for the module dependencies - they should be set to 'use Project SDK' but they might not be. That's usually the source of the kind of error you're seeing.

On Android Studio it's possible that the SDK may not be completely or properly installed. Setting the SDK's to an older version worked for me. – SMBiggs Jan 10 '17 at 04:26
