Map Bounds Are Not Properly Set To Query Map Features

[saadsaifse]

Hi, in the code here the screen coordinates are not set to the correct coordinates for android. Should be set to mpbounds.NorthWest for tl and mpbounds.SouthEast for br

Right now, this function does not return any features

var tl = map.Projection.ToScreenLocation(mpbounds.NorthEast);
var br = map.Projection.ToScreenLocation(mpbounds.NorthEast);
var region = tl.ToRectF(br);
