All Implemented Interfaces:

android.hardware.Camera.AutoFocusCallback
```
public interface CameraHost
 implements Camera.AutoFocusCallback
                    
```
Specification of a CameraHost, which is the primary way by which an app will interact with the library. This allows for a single code base supporting those using CameraView directly, CameraFragment, the CameraFragment for the Android Support package's backport of fragments, and who knows what else in the future. A concrete implementation of this class, SimpleCameraHost, provides reasonable defaults for all of the functionality. Hence, you can either extend SimpleCameraHost and override where needed, or implement your own CameraHost from scratch. *

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`public enum`	`CameraHost.RecordingHint`	Indication of what purpose we plan to put the camera towards. If your use of the camera is single-purpose, return STILL_ONLY (for photos) or VIDEO_ONLY (for videos). If you support both (all the time or via some sort of user-selectable mode), use ANY. NONE indicates that something else should be making this decision (for internal use only).
`public enum`	`CameraHost.FailureReason`	Indication of why we were unable to open up a camera. NO_CAMERAS_REPORTED will be used if getCameraId() returns a negative number. Exceptions raised when the camera is opened will return UNKNOWN.

`abstract Camera.Parameters`	`adjustPictureParameters(PictureTransaction xact, Camera.Parameters parameters)`	Implement this to configure the Camera.Parameters just prior to taking a photo.
`abstract Camera.Parameters`	`adjustPreviewParameters(Camera.Parameters parameters)`	Implement this to configure the Camera.Parameters for the purposes of the preview.
`abstract void`	`autoFocusAvailable()`	This will be called by the library to let you know that auto-focus is available for your use, so you can update your UI accordingly.
`abstract void`	`autoFocusUnavailable()`	This will be called by the library to let you know that auto-focus is not available for your use, so you can update your UI accordingly.
`abstract void`	`configureRecorderAudio(int cameraId, MediaRecorder recorder)`	This will be called by the library to give you a chance to configure the audio of the MediaRecorder, just prior to beginning to record a video.
`abstract void`	`configureRecorderOutput(int cameraId, MediaRecorder recorder)`	This will be called by the library to give you a chance to configure the output of the MediaRecorder, just prior to beginning to record a video.
