How to add custom system service name to @ServiceName StringDef?

Question

In some of our Activities, we've overridden getSystemService() method to return some custom objects for custom service names. It works well for us, to pass down some object to a View somewhere deep inside such Activity.

But in Android Studio we get an error generated by a lint inspection in a line that gets our custom system service:

return (CustomService) context.getSystemService(SERVICE_NAME);

I know lint uses a @ServiceName annotation on getSystemService() which is defined via a @StringDef in Context class. I would like to know how I can extend this definition to include our custom service names.

I wouldn't like to turn of this very usefull inspection nor suppress this error every time we use our custom system service. That's why I hope it is possible to add custom names for lint to recognize that this call is correct.

If editing Context.java is not an option (i.e., you're not building a custom ROM) then there's nothing you can do apart from maybe suppressing the error somehow -- [this](http://stackoverflow.com/q/27474142/507761) might do it? — Matthew Read, Jul 09 '15 at 16:03

public class SomeClass{

    public static final String SERVICE_1= "SERVICE_1";
    public static final String SERVICE_2= "SERVICE_2";
    public static final String SERVICE_3= "SERVICE_1";

    @StringDef({SERVICE_1, SERVICE_2, SERVICE_3})
    @Retention(RetentionPolicy.SOURCE)
    public @interface ServiceName{}

    ...

    public Object getService(@ServiceName String name){
        //Resolve service by string name
        ...
    }

}

to use @StringDef annotation add following dependencies to gradle build file

dependencies {
    compile 'com.android.support:support-annotations:23.1.1'
}
