Android camera resulted image should be rotated after the capture?

Question

I'm writing an Android application that uses the camera. I'm setting camera display orientation to 90, my activity is in a portrait orientation:

camera.setDisplayOrientation(90); 

I'm getting a well oriented preview picture, but the resulting image is rotated to -90 degrees (counter clockwise) and

exif.getAttribute(ExifInterface.TAG_ORIENTATION) 

returns ORIENTATION_NORMAL
Is it expected behavior? Should I rotate resulted image after the capture?

Device - Nexus S, API - 10

Try this

try {         File f = new File(imagePath);         ExifInterface exif = new ExifInterface(f.getPath());         int orientation = exif.getAttributeInt(                 ExifInterface.TAG_ORIENTATION,                 ExifInterface.ORIENTATION_NORMAL);          int angle = 0;          if (orientation == ExifInterface.ORIENTATION_ROTATE_90) {             angle = 90;         } else if (orientation == ExifInterface.ORIENTATION_ROTATE_180) {             angle = 180;         } else if (orientation == ExifInterface.ORIENTATION_ROTATE_270) {             angle = 270;         }          Matrix mat = new Matrix();         mat.postRotate(angle);         BitmapFactory.Options options = new BitmapFactory.Options();         options.inSampleSize = 2;          Bitmap bmp = BitmapFactory.decodeStream(new FileInputStream(f),                 null, options);         bitmap = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(),                 bmp.getHeight(), mat, true);         ByteArrayOutputStream outstudentstreamOutputStream = new ByteArrayOutputStream();         bitmap.compress(Bitmap.CompressFormat.PNG, 100,                 outstudentstreamOutputStream);         imageView.setImageBitmap(bitmap);      } catch (IOException e) {         Log.w("TAG", "-- Error in setting image");     } catch (OutOfMemoryError oom) {         Log.w("TAG", "-- OOM Error in setting image");     } 

It will work

Problem is the camera orientation is a complete disaster (as is capturing an image) because OEMs do not adhere to the standard. HTC phones do things one way, Samsung phones do it a different way, the Nexus line seems to adhere no matter which vendor, CM7 based ROMs I think follow the standard no matter which hardware, but you get the idea. You sort of have to determine what to do based on the phone/ROM. See discussion here: Android camera unexplainable rotation on capture for some devices (not in EXIF)
