Google Maps Android API V2 problems -
i'm trying put working example of google maps android api v2. have found 4 tutorials describe how (dj-android, vogella, 2 tutorials official docs) , none of them work. have found dozen posts, one, many other developers, same problem: "binary xml file line #x error inflating class". on stackoverflow, none of dozen posts have single accepted answer. know of no working examples of api anywhere on internet.
the contents of project pasted below. think have has been recommended various posts but, many others, i'm getting inflation run time error.
this actual project taken vogella tutorial wouldn't compile. applied fixes other posts of same problem.
can tell me how make work? know of working example anywhere? thanks, gary
