      CameraHost getCameraHost()
      void setCameraHost(CameraHost host) Call this (or override getCameraHost()) to supply the CameraHost used for most of the detailed interaction with the camera.
      void takePicture() Call this to take a picture and get access to a byte array of data as a result (e.g., to save or stream).
      void takePicture(boolean needBitmap, boolean needByteArray) Call this to take a picture.
      void takePicture(PictureTransaction xact) Call this to take a picture.
      boolean isRecording()
      void record() Call this to begin recording video.
      void stopRecording() Call this to stop the recording triggered earlier by a call to record()
      int getDisplayOrientation()
      void lockToLandscape() Call this to lock the camera to landscape mode (with a parameter of true), regardless of what the actual screen orientation is.
      void unlocklockOrientation() Call this to set the camera to unspecified orientation mode.
      void autoFocus() Call this to begin an auto-focus operation (e.g., in response to the user tapping something to focus the camera).
      void cancelAutoFocus() Call this to cancel an auto-focus operation that had been started via a call to autoFocus().
      boolean isAutoFocusAvailable()
      void restartPreview() If you are in single-shot mode and are done processing a previous picture, call this to restart the camera preview.
      String getFlashMode()
      ZoomTransaction zoomTo(int level) Call this to begin populating a ZoomTransaction, with the eventual goal of changing the camera's zoom level.
      void startFaceDetection() Calls startFaceDetection() on the CameraView, which in turn calls startFaceDetection() on the underlying camera.
      void stopFaceDetection() Calls stopFaceDetection() on the CameraView, which in turn calls startFaceDetection() on the underlying camera.
      boolean doesZoomReallyWork()

      • setCameraHost

         void setCameraHost(CameraHost host)

        Call this (or override getCameraHost()) to supply the CameraHost used for most of the detailed interaction with the camera.

        Parameters:
        host - a CameraHost instance, such as a subclass of SimpleCameraHost

      • takePicture

         void takePicture()

        Call this to take a picture and get access to a byte array of data as a result (e.g., to save or stream).

      • takePicture

         void takePicture(boolean needBitmap, boolean needByteArray)

        Call this to take a picture.

        Parameters:
        needBitmap - true if you need to be passed a Bitmap result, false otherwise
        needByteArray - true if you need to be passed a byte array result, false otherwise

      • takePicture

         void takePicture(PictureTransaction xact)

        Call this to take a picture.

        Parameters:
        xact - PictureTransaction with configuration data for the picture to be taken

      • record

         void record()

        Call this to begin recording video.

      • stopRecording

         void stopRecording()

        Call this to stop the recording triggered earlier by a call to record()

      • lockToLandscape

         void lockToLandscape()

        Call this to lock the camera to landscape mode (with a parameter of true), regardless of what the actual screen orientation is.

      • unlocklockOrientation

         void unlocklockOrientation()

        Call this to set the camera to unspecified orientation mode.

      • autoFocus

         void autoFocus()

        Call this to begin an auto-focus operation (e.g., in response to the user tapping something to focus the camera).

      • cancelAutoFocus

         void cancelAutoFocus()

        Call this to cancel an auto-focus operation that had been started via a call to autoFocus().

      • restartPreview

         void restartPreview()

        If you are in single-shot mode and are done processing a previous picture, call this to restart the camera preview.

      • zoomTo

         ZoomTransaction zoomTo(int level)

        Call this to begin populating a ZoomTransaction, with the eventual goal of changing the camera's zoom level.

        Parameters:
        level - a value from 0 to getMaxZoom() (called on Camera.

      • startFaceDetection

         void startFaceDetection()

        Calls startFaceDetection() on the CameraView, which in turn calls startFaceDetection() on the underlying camera.

      • stopFaceDetection

         void stopFaceDetection()

        Calls stopFaceDetection() on the CameraView, which in turn calls startFaceDetection() on the underlying camera.
