[android-developers] trying to get polylines to work in google maps api v2

2013-01-11 Thread John Merlino 
Using google maps api v2, I had multiple markers displaying correctly
but I wanted to add a line joining them, so I added the polyline
functionality below. However, when I rendered map again, now it just
shows map without markers or line:

 IteratorMapString, String iterator2 = historyData.iterator();
while(iterator2.hasNext()){

MapString, String item = 
iterator2.next();

double currentLat = 
Double.parseDouble(item.get(latitude));
double currentLong = 
Double.parseDouble(item.get(latitude));



Double.parseDouble(item.get(longitude));


mMap.addMarker(new MarkerOptions()
.position(new LatLng(currentLat, currentLong))
.title(item.get(address)));



Polyline line = 
mMap.addPolyline(new PolylineOptions()
   .add(new LatLng(currentLat, 
currentLong))
   .width(5)
   .color(Color.RED));


}

The fact that you're using latitude for currentLong would probably skew
things on the map ...
