Buggy source:
public void setDefaultCameraParameters(Camera camera,Camera.CameraInfo cameraInfo){
  Camera.Parameters parameters=camera.getParameters();
  parameters.setPictureFormat(ImageFormat.JPEG);
  List<Camera.Size> supportedSizes=parameters.getSupportedPictureSizes();

  boolean hasAutoFocus=supportedFocusModes != null && supportedFocusModes.contains(Camera.Parameters.FOCUS_MODE_AUTO);
  if (hasAutoFocus) {

  }
  if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {

  }

    float whRatio=(float)tempSize.width / tempSize.height;

      float tempWHRatio=(float)size.width / size.height;
      if (tempWHRatio == whRatio) {
