Re: [android-developers] Adding markers with different drawables on google map in android

I am multiplying by 1E6 because GeoPoint needs latitude/longitude in micro degrees. How to check if latitude/longitude are transposed?

Why are you multiplying by 1000000.0?

Also have you ensured that latitude and longitude are not transposed?

(I had an issue when creating a KML output file: I thought that because my label said latitude it was correct, and the bug only threw itself into light when the point appeared over the sea!)

Here are some of the points I am plotting:
"latitude":"30.2782345","longitude":"-82.1603470"
"latitude":"30.2768497","longitude":"-82.1673126"
"latitude":"30.2713966","longitude":"-82.1601944"
"latitude":"30.2767563","longitude":"-82.1324768"
"latitude":"30.2897949","longitude":"-82.1278839"
"latitude":"30.2755909","longitude":"-82.1269608"
"latitude":"30.2761593","longitude":"-82.1239471"

These are obtained from a webservice.I am multiplying each lat/lng value with 1000000.0 while creating GeoPoint with them.

Do you use modified latitude and longitude coordinates?

Can you give an example of what points you are plotting to?

I've zoomed it manually and searched for the pins.....still can't see any other pin than the source and the last added one.Zoomed the map as far as the zoom controlls allow.I'll recheck if the points are accurate.

will u plz explain?

You know the word is spelled "please", right? The 'z' doesn't even make sense ... :-)
Sorry, pet peeve ... anyway ...
 

I've used mapView.getController().zoomToSpan(sourcemarker.getLatSpanE6(), sourcemarker.getLonSpanE6());  won't that do the zooming?

I mean literally, physically zoom the map out yourself, with your finger, using the zoom controls on the map. Go looking for your markers to make sure they didn't up in Zimbabwe or something. When I started with adding a map to my app, I was trying to plot a bus stop in downtown Chicago but ended up placing it in the middle of the Atlantic Ocean. It happens - all it takes is one wrong digit ...
