1. android studio run error ... module
sol ) F4를 누르면 Module Setting이 나오는데 거기서 아래와 같이 셋팅을 한다.
I fixed this by adding facets in Module settings. They were missing. right click on project > open Module settings > Facets > Add facets ( "+" sign at the top ) > Android. After adding facets you will have modules.
UPDATE:
For latest version of gradle, Facets have been removed, you can directly add modules now. right click on project > open Module settings > Add module ( "+" sign at the top ) > Phone and Tablet Application (Now you can create a new module and configure it).
