We have to develop a new application which main function is to take photos/videos or browse existing photos from gallery and share them with FB friends.
In order to share photos/videos users shall navigate to camera and run it,than there is an option 'Browse from gallery' , from where user can access its gallery.
As I have investigated all the Android applications and social networks, all of them firstly ask 'From where to you want to browse?'and there is 2 option
2.Take new photos
The user is free to choose which one to open. He is not forced to first run the camera, which is heavy process for mobiles and than navigate to gallery.
Which way is the right way?Run the camera and than give the option to navigate to gallery? Or let the user to choose from the beginning , Camera or Gallery? Is there any guideline I could read?
Only Instagram first runs the camera and than gives an option for gallery.
