How to use the Vibrator in an Android Library Module

My goal is to make a simple library with some basic vibration methods so that I can have a more diverse and native set of options in some other frameworks. My problem is that I cannot use getActivity() or getSystemService(Context.VIBRATOR_SERVER) inside the library.

Here is the library class I have so far: 

import android.os.Vibrator;
public class Vibration {

private Vibrator _vibrator;

     public static void Vibrate(long milliseconds ){
         Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
         //getActivity().getSystemService(Context.CONNECTIVITY_SERVICE);
         v.vibrate(VibrationEffect.createOneShot(
            milliseconds,VibrationEffect.DEFAULT_AMPLITUDE));
     }
}

I am getting Cannot resolve symbol 'Context', and the same for getSystemService

Anyone have an idea of to call these methods from the library?

you need to pass context object in Vibrate() method as below:

public static void Vibrate(long milliseconds, Context context) {
    Vibrator v = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
    v.vibrate(VibrationEffect.createOneShot(
            milliseconds, VibrationEffect.DEFAULT_AMPLITUDE));
}

and for Context you need to importimport android.content.Context;
