Android studio not found R.id.****

Question

It has worked fine till now, but I apparently touched something and something happened.
Android Studio did not found R.id.**** and R.layout.****.

What do I need to do to resolve the problem?

Answer 1

I got the same error and just found out I imported automatically android.R. I just had to remove it.

Check if you have import android.R at the top of your file.

Answer 2

check build.gradle(app). if there is not apply plugin: 'kotlin-android-extensions' on top of page include it. That works for me.

or type id 'kotlin-android-extensions' instead.
