Transform meters into Pixels

I would like to transform a metric value into pixels to add to a Marker.

In earlier versions I used it as follows:

import com.google.android.maps.Projection;
Projection projection = mapView.getProjection();
float raio = projection.metersToEquatorPixels(metros);  

But in new versions ( com.google.android.gms.maps.Projection ) this method is not available!

How do I transform meter into Pixels?
