public final class CameraInfo

  1. Object
  2. CameraInfo

Describes a physical camera available on the device.

Returned by Camera#getCameras() and Camera#getDefault(CameraFacing). Instances are immutable and may be passed to Camera#open(CameraInfo, CameraSessionOptions).

Constructors

public CameraInfo(String id, CameraFacing facing, Dimension[] photoSizes, Dimension[] previewSizes, boolean hasFlash, boolean hasAutoFocus)Used by platform implementations.

Methods

public String getId()Opaque, platform-specific identifier.
public CameraFacing getFacing()Direction this camera faces relative to the device screen.
public Dimension[] getPhotoSizes()Supported still-photo resolutions, largest first.
public Dimension[] getPreviewSizes()Supported preview/frame-stream resolutions.
public boolean hasFlash()True if this camera has a flash/torch the application can drive via CameraSession#setFlashMode(FlashMode).
public boolean hasAutoFocus()True if this camera supports tap-to-focus / autofocus.
