Camera preview still black

Question

I\'m trying the camera preview on my Android applications. When I try on my real devices, it gives me black screen.

This is my code and it doesn\'t throw any error,

Answer 1

Bit of an odd issue I've just found relating to black camera preview. In my case it turned out to be because I had the manifest options

PARTIAL_WAKE_LOCK and also REQUEST_INSTALL_PACKAGES

Why these affect the camera like this I don't know - or whether it's just related to the device I'm using - but removing these permissions resolved my issue. It's taken me 2 hours of stripping a project down to figure out where the issue came in!
