I already tried to generate my key in https://developers.google.com/android/maps-api-signup with too much MD5 many times but doesn’t work .
When a try MapView using
var mapIntent = new Intent (Intent.ActionView, geoUri)
it works but i can’t put my overlay items .
I need to use my MapView from layout but just show lines and overlayitems.
I tried use the example HelloMap in cellphone but happen the same thing doesn’t show map just overlay items.

Instead of generate the release .apk i publish the .apk as i will publish into store !
My MapView worked on both 3g and wi-fi.
