    It happens if your class is missing the link of R.Class which you may have to import. So, Before starting the class you can simply start by

    import Your_Package_name.R;

    E.g.

    import com.example.myproject.R;

    You can manually write this when Clean/Rebuild project is not the solution.

    Use-case:

    import javax.crypto.spec.SecretKeySpec;
    import javax.net.ssl.HttpsURLConnection;
    import com.example.jsonwebservice.R;
    

    This worked for me.
