Re: [android-developers] itemizedOverlay, onTap
While creating the object of your class helloItemizedOverlay you are
supposed to pass the current context. Use the constructor
helloItemizedOverlay(Drawable defaultMarker, Context
context). When you do this your context will not be null.

Re: [android-developers] itemizedOverlay, onTap
While creating the object of your class helloItemizedOverlay you are
supposed to pass the current context. Use the constructor
helloItemizedOverlay(Drawable defaultMarker, Context context). When you do
this your context will not be null.
This constructor in turn is calling the super constructor.
Thanks
