final void setPreviewTexture(SurfaceTexture surfaceTexture) Sets the SurfaceTexture to be used for live preview. So the users can see themselves as looking into a mirror. Then preview callback is invoked with the buffer. Nonetheless, if you only have limited RAM space, you might need to purchase additional RAM chips if you'd like to continue using your personal computer smoothly.

After focus completes, face detection will resume sending face callbacks.

false : true, mCamera); return; case ERROR_CALLBACK: Log.e(TAG, "Error " + msg.arg1); if (mErrorCallback != null) mErrorCallback.onError(msg.arg1, mCamera); return; default: Log.e(TAG, "Unknown message type " + msg.what); return; } } } If the apps call autoFocus(AutoFocusCallback), the camera will stop sending face callbacks. interface Camera.ShutterCallback This interface was deprecated in API level 21. previewEnabled public final boolean previewEnabled() Return current preview state.

final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object.

If this method has never been called, null will be returned by the raw image callback since there is no image callback buffer available. Using this method, the shutter sound can be disabled. FIXME: Unhide before release setPreviewCallback public final void setPreviewCallback(Camera.PreviewCallbackcb) Installs a callback to be invoked for every preview frame in addition to displaying them on the screen. reconnect public final void reconnect() throws java.io.IOException Reconnects to the camera service after another process used it.

You must call release() when you are done using the camera, otherwise it will remain locked and be unavailable to other applications. Throws: java.io.IOException - if a connection cannot be re-established (for example, if the camera is still in use by another process). The starting position is 0 (landscape).See Also:setPreviewDisplay(SurfaceHolder) setZoomChangeListener public final void setZoomChangeListener(Camera.OnZoomChangeListenerlistener) Registers a listener to be notified when the zoom value is updated by the camera driver during smooth zoom.

Parameters:degrees - the angle that the picture will be rotated clockwise.

The camera service will initiate a series of callbacks to the application as the image capture progresses. Didn't you find the solution you were looking for? interface Camera.ErrorCallback This interface was deprecated in API level 21. There is no need to call this after recording starts or stops.

staticint CAMERA_ERROR_SERVER_DIED Media server died. If you are not recording video, you probably do not need this method.
