I've found similar solution. You can use CameraUpdateFactory.newLatLngBounds(LatLngBounds bounds, int padding)

Here is an example:

Builder boundsBuilder = LatLngBounds.builder();
ArrayList<LatLng> decodedPoints = (ArrayList<LatLng>) PolyUtil.decode(step);
for (LatLng point : decodedPoints) {
    boundsBuilder.include(point);
}
LatLngBounds bounds = boundsBuilder.build();
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngBounds(bounds, 10);
map.moveCamera(cameraUpdate);

Use zoomToSpan() on MapController. Compute the span based on the distances between your points. If your points are not centered, either take that into account (by increasing the desired span) or recenter the map.
