set orientation of android camera started with intent ACTION_IMAGE_CAPTURE [duplicate]

Answer 1

The above answer is very thorough, but I found I had to do a little bit more in order for every case to work, especially if you're dealing with images from other sources such as the Gallery or Google Photos. Here's my DetermineOrientation method. I have a utility class where this is located so I have to pass in the Activity in order to use managedQuery(which btw is deprecated so use cautiously). The reason I have to use two methods is because, depending on the source of the image, ExifInterface will not work. For instance, if I take a camera photo, Exif works fine. However, if I'm also choosing images from the Gallery or Google Drive, Exif does not work and always returns 0. Hope this helps someone.

public static int DetermineOrientation(Activity activity, Uri fileUri)
{
    int orientation = -1;
    int rotate = 0;
    try {

        ExifInterface exif = new ExifInterface(fileUri.getPath());
        orientation = exif.getAttributeInt(
                ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
        rotate = 0;
        switch (orientation) {
            case ExifInterface.ORIENTATION_ROTATE_270:
                rotate = 270;
            case ExifInterface.ORIENTATION_ROTATE_180:
                rotate = 180;
            case ExifInterface.ORIENTATION_ROTATE_90:
                rotate = 90;
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    if(rotate == 0)
    {
        String[] orientationColumn = {MediaStore.Images.Media.ORIENTATION};
        Cursor cur = activity.managedQuery(fileUri, orientationColumn, null, null, null);
        orientation = -1;
        if (cur != null && cur.moveToFirst()) {
            orientation = cur.getInt(cur.getColumnIndex(orientationColumn[0]));
        }

        if(orientation != -1)
        {
            rotate = orientation;
        }
    }

    return rotate;
}

http://developer.android.com/reference/android/media/ExifInterface.html#TAG_ORIENTATION

So if in

Activity.onActivityResult(data, request, result) {
 if (request == PHOTO_REQUEST && result == RESULT_OK) {
   ...
   Uri imageUri = ...
   File imageFile = new File(imageUri.toString());
   ExifInterface exif = new ExifInterface(imageFile.getAbsolutePath());
   int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
   int rotate = 0;
   switch(orientation) {
     case ExifInterface.ORIENTATION_ROTATE_270:
         rotate-=90;
     case ExifInterface.ORIENTATION_ROTATE_180:
         rotate-=90;
     case ExifInterface.ORIENTATION_ROTATE_90:
         rotate-=90;
   }
   Canvas canvas = new Canvas(bitmap);
   canvas.rotate(rotate);
 }

Does this help at all?

Just to add to Greg's great answer, here's a whole "category" to do the job:

public static int neededRotation(File ff)
        {
        try
            {

            ExifInterface exif = new ExifInterface(ff.getAbsolutePath());
            int orientation = exif.getAttributeInt(
               ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

            if (orientation == ExifInterface.ORIENTATION_ROTATE_270)
                { return 270; }
            if (orientation == ExifInterface.ORIENTATION_ROTATE_180)
                { return 180; }
            if (orientation == ExifInterface.ORIENTATION_ROTATE_90)
                { return 90; }
            return 0;

            } catch (FileNotFoundException e)
            {
            e.printStackTrace();
            } catch (IOException e)
            {
            e.printStackTrace();
            }
        return 0;
        }

you'd use it more or less like this ...

public void onActivityResult(int requestCode, int resultCode, Intent data)
    {
    if (requestCode == REQUEST_IMAGE_CAPTURE) // && resultCode == RESULT_OK )
        {
        try
            {
            Bitmap cameraBmp = MediaStore.Images.Media.getBitmap(
                    State.mainActivity.getContentResolver(),
                    Uri.fromFile( Utils.tempFileForAnImage() )  );

            cameraBmp = ThumbnailUtils.extractThumbnail(cameraBmp, 320,320);
            // NOTE incredibly useful trick for cropping/resizing square
            // http://stackoverflow.com/a/17733530/294884

            Matrix m = new Matrix();
            m.postRotate( Utils.neededRotation(Utils.tempFileForAnImage()) );

            cameraBmp = Bitmap.createBitmap(cameraBmp,
                    0, 0, cameraBmp.getWidth(), cameraBmp.getHeight(),
                    m, true);

            yourImageView.setImageBitmap(cameraBmp);

            // to convert to bytes...
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            cameraBmp.compress(Bitmap.CompressFormat.JPEG, 75, baos);
            //or say cameraBmp.compress(Bitmap.CompressFormat.PNG, 0, baos);
            imageBytesRESULT = baos.toByteArray();

            } catch (FileNotFoundException e)
            {
            e.printStackTrace();
            } catch (IOException e)
            {
            e.printStackTrace();
            }

        return;
        }

    }

Hope it saves someone some typing in the future.
