I need to calculate the direction between two geolocation points (lat and log defined). I don’t really need the entire angle (I found something like this), but only N, NE, E, SE, S, SW, W, NW is fine.
Any help is appreciated
You can use Location.bearingTo ( http://developer.android.com/reference/android/location/Location.html#bearingTo%28android.location.Location%29 )
Create 2 location objects from your points, and you can get a precise bearing. Then you simply compare it to the 8 values. (like between -22.5 and +22.5 it’s N, until 67.5 it’s NE, until 112.5 it’s E, and so on)
