To look up coordinates in Google Maps on Android, you’ll need todrop a pin—tap and hold a spot on the mapto do this. You’ll see a red pin appear on the map and a Dropped Pinwindow at the bottom. The coordinates for the pinned location appear in theSearchbox at the top. You ...

And the differences between the data stored and the projected map when using lat/long. Thanks! EDIT This may be more specific to China and the infamous offset issue. Looking at the following coordinates: 31.230548,121.470965 for the Shanghai Art Museum on Google Maps and ditu...
