I am having real troubles getting even a simple Map app to open (both on AVD virtual device or on real Android phones). Using Eclipse / ADT up to date installation.
The code is more-or-less straight from a book chapter on GoogleMaps v2 ('Android Application Development Cookbook' by Wei-Meng Lee / Wrox). A few weeks ago before a SSD failure, I briefly had similar code running. I have left the code from the book untouched - downloaded / imported etc. Other simple helloworld and other apps run fine on the AVD etc.
I have:
- added the google-play-services-lib
- got my GoogleMapsv2 API key - leaving the package name unchanged
- trawled through loads of articles / questions here and elsewhere and compared code / checked for errors.
Nothing seems to help. After 4 weeks of frustration I am now begging for help (and possibly forgiveness if this is a simple mistake!)

I really do think I've tried everything before asking for help here.
(I used to hand-write Z80 assembly code and hand-convert it to Hex in the early 1980's - that was SO simple compared to this........)
Massive thanks for any help from you guys!
added later - here is my error log
