How can I find the orientation of a picture taken with Intent MediaStore.ACTION_IMAGE_CAPTURE?

Question

When I take a picture with Android's camera app, it detects the phone's orientation and saves the picture accordingly. So if I take a picture of a building, the roof will be on the topside, whether I hold the phone in landscape position or portrait.

However, when I use

Intent imageCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 

to get a picture, the camera app doesn't react to the orientation. If I hold the phone vertically (portrait), the resulting picture will be rotated, with said building's roof to the left of the screen.

How can I set the intent so that the camera will take the orientation into account?

Or can I deduce in some way in what orientation the picture was taken and rotate it myself afterwards?

Or is there another way?

Answer 1

I found the answer. The Exif of the image has an indicator of the orientation. Just in case, Exif can be viewed in Android like this:

ExifInterface exif = new ExifInterface("filepath");   exif.getAttribute(ExifInterface.TAG_ORIENTATION); 

Answer 2

Read from Exif if available, otherwise read from MediaStore

public static int getImageOrientation(Context context, String imagePath) {     int orientation = getOrientationFromExif(imagePath);     if(orientation <= 0) {         orientation = getOrientationFromMediaStore(context, imagePath);     }      return orientation; }  private static int getOrientationFromExif(String imagePath) {     int orientation = -1;     try {         ExifInterface exif = new ExifInterface(imagePath);         int exifOrientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION,                  ExifInterface.ORIENTATION_NORMAL);          switch (exifOrientation) {             case ExifInterface.ORIENTATION_ROTATE_270:                 orientation = 270;                  break;             case ExifInterface.ORIENTATION_ROTATE_180:                 orientation = 180;                  break;             case ExifInterface.ORIENTATION_ROTATE_90:                 orientation = 90;                  break;              case ExifInterface.ORIENTATION_NORMAL:                 orientation = 0;                  break;             default:                 break;         }     } catch (IOException e) {         Log.e(LOG_TAG, "Unable to get image exif orientation", e);     }      return orientation; }  private static int getOrientationFromMediaStore(Context context, String imagePath) {     Uri imageUri = getImageContentUri(context, imagePath);     if(imageUri == null) {         return -1;     }      String[] projection = {MediaStore.Images.ImageColumns.ORIENTATION};     Cursor cursor = context.getContentResolver().query(imageUri, projection, null, null, null);      int orientation = -1;     if (cursor != null && cursor.moveToFirst()) {         orientation = cursor.getInt(0);         cursor.close();     }      return orientation; }  private static Uri getImageContentUri(Context context, String imagePath) {     String[] projection = new String[] {MediaStore.Images.Media._ID};     String selection = MediaStore.Images.Media.DATA + "=? ";     String[] selectionArgs = new String[] {imagePath};     Cursor cursor = context.getContentResolver().query(IMAGE_PROVIDER_URI, projection,              selection, selectionArgs, null);      if (cursor != null && cursor.moveToFirst()) {         int imageId = cursor.getInt(0);         cursor.close();          return Uri.withAppendedPath(IMAGE_PROVIDER_URI, Integer.toString(imageId));     }       if (new File(imagePath).exists()) {         ContentValues values = new ContentValues();         values.put(MediaStore.Images.Media.DATA, imagePath);          return context.getContentResolver().insert(                     MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);     }       return null; }
