Need Help with adding a button or ImageView so i can switch to a front camera please help!!! Can anyone help me out and fast been trying to add it in but i keep getting an error on the switch camera. I tried implementing an intent that was a separate class to front camera but when switching back to the back camera the screen will stay black. I want to implement the front camera in correctly the way it should be please if anyone could help thanks. And if you please can please add the front camera source code into my project if you can thanks.
