我在我的代码中使用虚拟表面.它在运行4.2.1的Canvas HD中运行良好但是当我的nexus 5/S 3上部署了相同的应用程序时,它在camera.takepicture上提供RunTimeException

这是我的代码

  {
    camera = Camera.open(cameraId);
    if (camera != null)
   {
    SurfaceView dummy = new SurfaceView(context);
    try {
    camera.setPreviewDisplay(dummy.getHolder());
    } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
    }
    camera.startPreview();
    camera.takePicture(null, null, new PhotoHandler(context));

    }

logcat的:
