Blowup in View Message handling when map moved without setting mMainActivityCallbackHandler #105

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create a new OpenStreetMapView instance
2. Do not invoke setMainActivityCallbackHandler
3. Move the map

Since my application didn't need the activity callbacks (yet) I did not set a 
callback handler.  However the messages are fired anyway but with a null object 
which eventually leads to a null pointer exception.

It would be nice to not send messages when mMainActivityCallbackHandler is null.

What version of the product are you using? On what operating system?
