I tried several things to try to get the camera preview to show up in portrait on a SurfaceView. Nothing worked. I am testing on a Droid that has 2.0.1. I tr

You can try this (good for 2.2 or below). Here I rotate the image before saving it to sd card. But it is only for portrait mode. If you had to make it for both mode then you should check camera orientation and put some check before capturing image.

PictureCallback jpegCallback = new PictureCallback() {
   public void onPictureTaken(byte[] data, Camera camera) {
      FileOutputStream outStream = null;
      try {
        imageFilePath = getFilename();
        InputStream is = new ByteArrayInputStream(data);
        Bitmap bmp = BitmapFactory.decodeStream(is);
        // Getting width & height of the given image.
        if (bmp != null){
           int w = bmp.getWidth();
           int h = bmp.getHeight();
           // Setting post rotate to 90
           Matrix mtx = new Matrix();
           mtx.postRotate(90);
           // Rotating Bitmap
           Bitmap rotatedBMP = Bitmap.createBitmap(bmp, 0, 0, w, h, mtx, true);
           ByteArrayOutputStream stream = new ByteArrayOutputStream();
           rotatedBMP.compress(Bitmap.CompressFormat.PNG, 100, stream);
           byte[] byteArray = stream.toByteArray(); 
           outStream = new FileOutputStream
                              (String.format(imageFilePath,System.currentTimeMillis()));
           outStream.write(byteArray);
           outStream.close();
        } else {
           outStream = new FileOutputStream
                              (String.format(imageFilePath,System.currentTimeMillis()));
           outStream.write(data);
           outStream.close();           
        }       

        preview.camera.startPreview();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
    }
  }
};
