QCamera on Android and continuous focus

[imironchik]

Hello.

I set camera focus mode on Android device with.

m_cam->focus()->setFocusMode( QCameraFocus::ContinuousFocus );

m_cam->focus()->isFocusModeSupported( QCameraFocus::ContinuousFocus );

Reports true.

But I see focus on the distant object, I don't see auto focus working. The focus always the same. Maybe I missed something? What should I do to make auto focus to work on Android device?

Tried this:

m_cam->focus()->setFocusMode( QCameraFocus::ContinuousFocus |
    QCameraFocus::MacroFocus );

The same behavior. No focus on the objects in 0.1 - 0.5 m...

Looks like this doesn't work. It is necessary to invoke QCamera::searchAndLock() from time to time...

So, my solution is:

m_cam->focus()->setFocusMode( QCameraFocus::MacroFocus );

and I do:

m_cam->searchAndLock();

on image changes (significant changes).
