camera - Android App only working One time, then crashes -
okay having problem getting app work. have game needs few pictures , strings user. have opening screen (openingscreen) acts splash screen opens menu (menuscreen). there user can pick go game or go activity shows current pictures (pickscreen). user can go activity , there open activity gives larger version of picture have picked or default picture (picone). here user has option take new picture , change current strings. part of works great. problem occurs when:
after user picks picture , backs out of app. next time open it, force close either when go pickscreen or after press done after taking new picture , when go picone activity. not same thing everytime, crashes @ 1 of points.
the other issue happens when change 3 string names. after pressing save , going pickscreen, app crashes when going picone or if out of app crashes when going menuscreen pickscreen.
i know lot of code at, have spent lot of time looking around , getting code different places app , @ point cannot figure out. figure there many people more knowledge me out there, asking help. know cannot ask question without showing have been doing work, here is.
why may app work once , crash in various spots second time in? way work fine after force close, again once. , why force close when change strings?
thanks everyone!!

logcat give stack trace, , use debug pinpoint place it's crashing. debugging modern application reading through code, oop code, impossible.
