Are you adding the map with the designer? This is required in GoogleMaps v2 library.

 

[schimanski]

Oh, sorry I have overlooked it..now it works

Are you adding the map with the designer?

Could you explain the exact difference between adding by code and by designer? (except "auto initialize")

 

[Erel]

Version 2 of GoogleMaps library is implemented as a custom view and it expects several properties to be set during initialization.
It is very simple to add it with the designer. You can create a layout with only the map and add it to your existing program.

Just wanted to know where the difference is
