everyone. i am making an app like craiglist. it takes the photo of the item and puts it into image view. and i have 2 radio buttons. and everytime i click on radio buttons the app crashes. the camera part is working btw. ok i have couple of questions about my app that i cant figure out how to do.. 1. how do i prevent it from crashes which occurs while selecting radio button. 2. how to i pass the user selected radio buttoon value into another screen's textview. 3. how do i print the image that i captured in both screens. like have the same image pass into another activity. 4. also the price for the item. how do i make it to display into another screen.?
below are my code. feel free to edit and making corrections. thank you!
