Creating a polygonal geofence

Question

Does anyone know how to create a polygonal geofence in Android? I know that Android supports circular (i.e., lat/long + radius) geofences, but I need more precise control over their boundaries.

Huh. I searched for an answer several times and I didn't ever come across that. I'll look into it today. — Dylan Knowles, Sep 10 '13 at 16:39

For concerns about CPU & power consume, I recommend to use the solution decribed here.

Create a fake circular geo-fence around your Polygon
When a geofence alert is thrown for this circular geofence, evaluate if it is also inside your Polygon using the answer provided by Karl.

Good idea! As far as I know they do that in video games as well to make collision detection more efficient. I never would've thought to use it in geofences. Thanks! – Dylan Knowles Jul 14 '16 at 02:06
