/**
|
|
* The Camera class is used to set image capture settings, start/stop preview,
|
|
* snap pictures, and retrieve frames for encoding for video. This class is a
|
|
* client for the Camera service, which manages the actual camera hardware.
|
|
*
|
|
* <p>To access the device camera, you must declare the
|
|
* {@link android.Manifest.permission#CAMERA} permission in your Android
|
|
* Manifest. Also be sure to include the
|
|
* <a href="{@docRoot}guide/topics/manifest/uses-feature-element.html"><uses-feature></a>
|
|
* manifest element to declare camera features used by your application.
|
|
* For example, if you use the camera and auto-focus feature, your Manifest
|
|
* should include the following:</p>
|
|
* <pre> <uses-permission android:name="android.permission.CAMERA" />
|
|
* <uses-feature android:name="android.hardware.camera" />
|
|
* <uses-feature android:name="android.hardware.camera.autofocus" /></pre>
|
|
*
|
|
* <p>To take pictures with this class, use the following steps:</p>
|
|
*
|
|
* <ol>
|
|
* <li>Obtain an instance of Camera from {@link #open(int)}.
|
|
*
|
|
* <li>Get existing (default) settings with {@link #getParameters()}.
|
|
*
|
|
* <li>If necessary, modify the returned {@link Camera.Parameters} object and call
|
|
* {@link #setParameters(Camera.Parameters)}.
|
|
*
|
|
* <li>If desired, call {@link #setDisplayOrientation(int)}.
|
|
*
|
|
* <li><b>Important</b>: Pass a fully initialized {@link SurfaceHolder} to
|
|
* {@link #setPreviewDisplay(SurfaceHolder)}. Without a surface, the camera
|
|
* will be unable to start the preview.
|
|
*
|
|
* <li><b>Important</b>: Call {@link #startPreview()} to start updating the
|
|
* preview surface. Preview must be started before you can take a picture.
|
|
*
|
|
* <li>When you want, call {@link #takePicture(Camera.ShutterCallback,
|
|
* Camera.PictureCallback, Camera.PictureCallback, Camera.PictureCallback)} to
|
|
* capture a photo. Wait for the callbacks to provide the actual image data.
|
|
*
|
|
* <li>After taking a picture, preview display will have stopped. To take more
|
|
* photos, call {@link #startPreview()} again first.
|
|
*
|
|
* <li>Call {@link #stopPreview()} to stop updating the preview surface.
|
|
*
|
|
* <li><b>Important:</b> Call {@link #release()} to release the camera for
|
|
* use by other applications. Applications should release the camera
|
|
* immediately in {@link android.app.Activity#onPause()} (and re-{@link #open()}
|
|
* it in {@link android.app.Activity#onResume()}).
|
|
* </ol>
|
|
*
|
|
* <p>To quickly switch to video recording mode, use these steps:</p>
|
|
*
|
|
* <ol>
|
|
* <li>Obtain and initialize a Camera and start preview as described above.
|
|
*
|
|
* <li>Call {@link #unlock()} to allow the media process to access the camera.
|
|
*
|
|
* <li>Pass the camera to {@link android.media.MediaRecorder#setCamera(Camera)}.
|
|
* See {@link android.media.MediaRecorder} information about video recording.
|
|
*
|
|
* <li>When finished recording, call {@link #reconnect()} to re-acquire
|
|
* and re-lock the camera.
|
|
*
|
|
* <li>If desired, restart preview and take more photos or videos.
|
|
*
|
|
* <li>Call {@link #stopPreview()} and {@link #release()} as described above.
|
|
* </ol>
|
|
*
|
|
* <p>This class is not thread-safe, and is meant for use from one event thread.
|
|
* Most long-running operations (preview, focus, photo capture, etc) happen
|
|
* asynchronously and invoke callbacks as necessary. Callbacks will be invoked
|
|
* on the event thread {@link #open(int)} was called from. This class's methods
|
|
* must never be called from multiple threads at once.</p>
|
|
*
|
|
* <p class="caution"><strong>Caution:</strong> Different Android-powered devices
|
|
* may have different hardware specifications, such as megapixel ratings and
|
|
* auto-focus capabilities. In order for your application to be compatible with
|
|
* more devices, you should not make assumptions about the device camera
|
|
* specifications.</p>

|
|
* Sets the rotation angle in degrees relative to the orientation of
|
|
* the camera. This affects the pictures returned from JPEG {@link
|
|
* PictureCallback}. The camera driver may set orientation in the
|
|
* EXIF header without rotating the picture. Or the driver may rotate
|
|
* the picture and the EXIF thumbnail. If the Jpeg picture is rotated,
|
|
* the orientation in the EXIF header will be missing or 1 (row #0 is
|
|
* top and column #0 is left side).
|
|
*
|
|
* <p>If applications want to rotate the picture to match the orientation
|
|
* of what users see, apps should use {@link
|
|
* android.view.OrientationEventListener} and {@link CameraInfo}.
|
|
* The value from OrientationEventListener is relative to the natural
|
|
* orientation of the device. CameraInfo.orientation is the angle
|
|
* between camera orientation and natural device orientation. The sum
|
|
* of the two is the rotation angle for back-facing camera. The
|
|
* difference of the two is the rotation angle for front-facing camera.
|
|
* Note that the JPEG pictures of front-facing cameras are not mirrored
|
|
* as in preview display.
|
|
*
|
|
* <p>For example, suppose the natural orientation of the device is
|
|
* portrait. The device is rotated 270 degrees clockwise, so the device
|
|
* orientation is 270. Suppose a back-facing camera sensor is mounted in
|
|
* landscape and the top side of the camera sensor is aligned with the
|
|
* right edge of the display in natural orientation. So the camera
|
|
* orientation is 90. The rotation should be set to 0 (270 + 90).
