how can i make one button do two things

Postby manutd » Mon Oct 26, 2009 10:53 pm

Hi

I need help with a camera application im creating.

Basically I want to take a photo, then automatically move to the next class just by pressing one button.

I have the code for the camera aspect working perfect, preview, layout, button to take photo and save locally. Just need help to move class automatically once the button has been pressed to take the photo.
