android.annotation cannot be resolved IntDef and NonNull

Question

I'm trying to run a sample android code in Andriod Studio, but when I try:

import android.annotation.IntDef;
import android.annotation.NonNull;

keep getting an error related to this line like:

the import android.annotation cannot be resolved

Any suggestion will be appreciated

I think it would be better if you work with the support annotations: add this dependency to your project and see if it works:

compile 'com.android.support:support-annotations:24.2.0'

I had faced the same problem and came across this question but was not answered. I could resolve this issue by following steps mentioned here.
After this, You shall sync the project with Gradle files.
Note: You may not find the same annotation path
e.g. import android.annotation.NonNull; --> import androidx.annotation.Nullable;
