target platform android vs. google api
I followed this tutorial: http://developer.android.com/resources/tutorials/views/hello-mapview.html
and it runs ok, except when I click on my icon in the map, the dialogue box does not come up.  And the application stops.  Did anyone else run into a similar problem?  

I don't know what is google api; can someone explain it to me please?  Does this mean that the code in above tutorial will not run on an android handset?
