There is official example code for this in the Android docs now (under setDisplayOrientation()):

public static void setCameraDisplayOrientation(Activity activity,
        int cameraId, android.hardware.Camera camera)
{
    android.hardware.Camera.CameraInfo info = new android.hardware.Camera.CameraInfo();
    android.hardware.Camera.getCameraInfo(cameraId, info);
    int rotation = activity.getWindowManager().getDefaultDisplay().getRotation();
    int degrees = 0;
    switch (rotation)
    {
    case Surface.ROTATION_0:
        degrees = 0;
        break;
    case Surface.ROTATION_90:
        degrees = 90;
        break;
    case Surface.ROTATION_180:
        degrees = 180;
        break;
    case Surface.ROTATION_270:
        degrees = 270;
        break;
    }

    int result;
    if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT)
    {
        result = (info.orientation + degrees) % 360;
        result = (360 - result) % 360; // compensate the mirror
    }
    else
    { // back-facing
        result = (info.orientation - degrees + 360) % 360;
    }
    camera.setDisplayOrientation(result);
}
