cannot resolve android symbol - android app - intelliJ

Question

I am using intellij-idea to develop android app. I created a project with an android module, but none of these :

import android.app.Activity;
import android         


        

Answer 1

Basically, this is because you didn't add Android SDK. So you need to add android SDK.

• go to Files and select project structure.
• go to project and select the project SDK
• click New and select Android SDK version
