The sample projects Toasts and Selectable are broken in 4.2.0-beta2

% cd $sdk420/samples/Selectable
% "$sdk420/bin/monkeyc" "-o" "bin/Selectable.prg" "-f" monkey.jungle "-y" "$developer_key" "-w" "-l" "1" "-d" "approachs60"

But if I compile it (the same project, taken from the 4.2.0beta2 samples) with 4.1.7 the compilation succeeds, and I can run the resulting program. So this is probably a bug in 4.2.0 (unless there's a subtle bug in the project that earlier compilers simply didn't notice).

For Toasts, I get

% cd $sdk420/samples/Toasts
% "$sdk420/bin/monkeyc" "-o" "bin/Toasts.prg" "-f" monkey.jungle "-y" "$developer_key" "-w" "-l" "1" "-d" "fenix7"
ERROR: Device 'fenix7' does not support API Level '4.2.0'.

And this time 4.1.7 agrees. So in this case it looks like the sample project needs fixing.
