Right way to use the @NonNull annotation in Android Studio

Question

I\'d like to use the @NonNull annotation in Android, but I can\'t figure out just the right way to do it. I propose you this example:

public voi         


        

Answer 1

Google examples do it as follows

import static com.google.common.base.Preconditions.checkNotNull;

...

public void doStuff(@NonNull String sParm){
     this.sParm= checkNotNull(s, "sParm cannot be null!");
}
