Turning Meters into Pixels

Question

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

In earlier versions it used if as follows:

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

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

How I Turn Metro into Pixels?
