I want to switch cameras from another activity

[sufyan5008]

hi there I want to switch cameras b/w front and back from settingsActivity. For example a user selects the camera to the front or back and then clicks save the record button should start recording to the selected camera. I want the exact same thing that it's currently doing by switching cameras with icon besides the capture icon but instead of the camera screen, I want in settingsActivity. can you please help me?
