Camera.AutoFocusCallback
| android.hardware.Camera.AutoFocusCallback
|
This interface was deprecated
in API level 21.
We recommend using the new android.hardware.camera2 API for new
applications.
Callback interface used to notify on completion of camera auto focus.
Devices that do not support auto-focus will receive a "fake"
callback to this interface. If your application needs auto-focus and
should not be installed on devices without auto-focus, you must
declare that your app uses the
android.hardware.camera.autofocus feature, in the
<uses-feature>
manifest element.
