  1. POAndroid: camera view - app crashes when I don't use a deprecated method
    text
    copied!<p>In my app, I am trying to set up the camera. My class extends SurfaceView and implements the SurfaceHolder.Callback methods.</p> <p>Here is some of my class:</p> <pre><code>public class CameraPreview extends SurfaceView implements SurfaceHolder.Callback{ private SurfaceHolder mHolder; private Camera.Parameters cameraParameters; private Camera camera; public CameraPreview(Context context) { super(context); mHolder = this.getHolder(); mHolder.addCallback(this); // If this is deprecated, why do I still need it? // It says deprecated, but app crashes when removed. mHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } @Override public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { Camera.Parameters parameters = camera.getParameters(); List&lt;Camera.Size&gt; previewSizes = parameters.getSupportedPreviewSizes(); Camera.Size previewSize = previewSizes.get(0); parameters.setPreviewSize(previewSize.width, previewSize.height); camera.setParameters(parameters); try { camera.stopPreview(); camera.setPreviewDisplay(mHolder); camera.startPreview(); } catch (IOException e) { e.printStackTrace(); } } @Override public void surfaceCreated(SurfaceHolder holder) { camera = Camera.open(); cameraParameters = camera.getParameters(); } @Override public void surfaceDestroyed(SurfaceHolder holder) { camera.stopPreview(); camera.release(); camera = null; } } </code></pre> <p>My question involves the "setType" method in the constructor. The API claims the method is deprecated and ignored. However, if I comment out that one line, the entire application crashes when I call camera.startPreview(). I am trying to figure out why this is. If it's ignored, then it shouldn't matter what I did with that method. It implies that there is something very wrong with this implementation.</p> <p>I am running Android 2.2 software.</p> <p>Any help would be appreciated.</p>
