A note about my environment: I use the command line (not Eclipse). I build using 'ant debug' - should I be using release? I'm using the "normal" apk - should I be using the -unaligned one?
Any advice would be appreciated, as this example is a large reason why I bought the book! Thanks in advance
Not able to run Chapter7_Sample_WhereAmI
