android - "Unfortunately the application (name) has stopped" message -
whenever run app (explore ca) getting message "unfortunately explore ca has stopped". app displays list of tours , gives option filter clicking on menu bar (fancy/cheap/all)
i found solution:
first step: right click on project -> java -> built path ->source ->add folder -> click gen , src ->click ok
second step: right click on project -> go properties -> libraries -> add jars -> , add jars of project libs folder
