androidx.annotation.RestrictTo

Denotes that the annotated element should only be accessed from within a specific scope (as defined by Scope).

Example of restricting usage within a library (based on gradle group ID): 

<code>
    @RestrictTo(GROUP_ID)
    public void resetPaddingToInitialValues() { ...
  </code>
Example of restricting usage to tests: 
<code>
    @RestrictScope(TESTS)
    public abstract int getUserId();
  </code>
Example of restricting usage to subclasses: 
<code>
    @RestrictScope(SUBCLASSES)
    public void onDrawForeground(Canvas canvas) { ...
  </code>
