Accessing the Android Camera in Qt
-
try to reboot your device first.

Hmm, I tried rebooting twice and made sure both times that camera was the only app running. I am deploying the app from Qt creator directly using Qt version 5.3, and as far as I know the example you suggested has not been modified.
-
declarative actually worked out of the box for me, which is why I'm confused. The fairly simple QML code had no trouble finding the camera on my device, so I'm debating whether or not I should look at the source of the QML Camera object to see what's going on there.
I will also try and run the camera app on my desktop with a webcam just to verify that it works.

No luck on a Nexus 4...I must be doing something wrong. If I ever figure it out I'll report back.
edit: I assume nothing special needs to be done regarding Permissions in the Manifest; there is a comment in the generated file that seems to indicate Qt takes care of this based on the needs of your app.

bq. Using Qt Multimedia with QWidgets has never been really supported on Android. You'll have to stick to QML for now. We'll add support for QWidget in 5.4.0. https://codereview.qt-project.org/#change,85577 makes sure the device doesn't get into an undefined state when trying to take a picture without a valid viewport.

I see. Thank you very much for your help, Vincent. Perhaps I'll explore getting the VideoOutput from the QML Camera as a buffer somehow.
