android - updated sdk today since then not been able to do an -

i updated android sdk today - since have had next problems

stopped exporting apk ( doesn't tell me why) can't run emulator (message on console says cannot find *.apk) i tried reloading project, after getting message id did not exist (even though there) managed eclipse recognise project, rejects switch/case statement on options menu

all worked yesterday - , have looked @ of solutions set forwards on other posts - , none seem work.

currently on android sdk tools 23.05 , eclipse luna 4.4.1 (running on linux may factor)

has thought how solve - suggestions appreciated.

i managed things work, although getting error related case statements in libraries. checked properties, , project not set library couldn't understand this.

i tried 1 thing should have done first - have done 30 years ago when first in - rebooted whole system.

now eclipse showed project beingness library, able reset , seems work.

i can assume update yesterday messed of memory, , eclipse lost bearings.
