Changing colour of Markers – Google Map V2 Android

You have a couple of characters wrong there. Compare your code to this:

googlemap.addMarker(new MarkerOptions()
    .position(new LatLng( 65.07213,-2.109375))
    .title("This is my title")
    .snippet("and snippet")
    .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ORANGE)));

Removed ) on third line, changed setSnippet to snippet and removed ; on forth line.
