Android getting an image from gallery comes rotated

You could use ExifInterface to modify the orientation:

public static Bitmap modifyOrientation(Bitmap bitmap, String image_absolute_path) throws IOException {
    ExifInterface ei = new ExifInterface(image_absolute_path);
    int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);

    switch (orientation) {
    case ExifInterface.ORIENTATION_ROTATE_90:
        return rotate(bitmap, 90);

    case ExifInterface.ORIENTATION_ROTATE_180:
        return rotate(bitmap, 180);

    case ExifInterface.ORIENTATION_ROTATE_270:
        return rotate(bitmap, 270);

    case ExifInterface.ORIENTATION_FLIP_HORIZONTAL:
        return flip(bitmap, true, false);

    case ExifInterface.ORIENTATION_FLIP_VERTICAL:
        return flip(bitmap, false, true);

    default:
        return bitmap;
    }
}

public static Bitmap rotate(Bitmap bitmap, float degrees) {
    Matrix matrix = new Matrix();
    matrix.postRotate(degrees);
    return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
}

public static Bitmap flip(Bitmap bitmap, boolean horizontal, boolean vertical) {
    Matrix matrix = new Matrix();
    matrix.preScale(horizontal ? -1 : 1, vertical ? -1 : 1);
    return Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
}

In order to get absolute path of your images from their uri, check this answer

2 One line solutions using Picasso and glide library

After spending a lot of time with a lot of solutions for image rotation problem I finally found two simple solutions. We don’t need to do any additional works.

Using Picasso library https://github.com/square/picasso

Picasso.with(context).load("http url or sdcard url").into(imageView);

Using glide library https://github.com/bumptech/glide

Glide.with(this).load("http url or sdcard url").into(imgageView);

Picasso and Glide are a very powerful library for handling images in your app includes. It will read image EXIF data and auto-rotates the images.

I use these static methods. The first determines the orientation and the second rotates the image shrinking it as needed.

public static int getOrientation(Context context, Uri photoUri) {

    Cursor cursor = context.getContentResolver().query(photoUri,
            new String[] { MediaStore.Images.ImageColumns.ORIENTATION }, null, null, null);

    if (cursor == null || cursor.getCount() != 1) {
        return 90;  //Assuming it was taken portrait
    }

    cursor.moveToFirst();
    return cursor.getInt(0);
}

/**
* Rotates and shrinks as needed
*/
public static Bitmap getCorrectlyOrientedImage(Context context, Uri photoUri, int maxWidth)
                throws IOException {

            InputStream is = context.getContentResolver().openInputStream(photoUri);
            BitmapFactory.Options dbo = new BitmapFactory.Options();
            dbo.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(is, null, dbo);
            is.close();


            int rotatedWidth, rotatedHeight;
            int orientation = getOrientation(context, photoUri);

            if (orientation == 90 || orientation == 270) {
                Log.d("ImageUtil", "Will be rotated");
                rotatedWidth = dbo.outHeight;
                rotatedHeight = dbo.outWidth;
            } else {
                rotatedWidth = dbo.outWidth;
                rotatedHeight = dbo.outHeight;
            }

            Bitmap srcBitmap;
            is = context.getContentResolver().openInputStream(photoUri);
            Log.d("ImageUtil", String.format("rotatedWidth=%s, rotatedHeight=%s, maxWidth=%s",
                    rotatedWidth, rotatedHeight, maxWidth));
            if (rotatedWidth > maxWidth || rotatedHeight > maxWidth) {
                float widthRatio = ((float) rotatedWidth) / ((float) maxWidth);
                float heightRatio = ((float) rotatedHeight) / ((float) maxWidth);
                float maxRatio = Math.max(widthRatio, heightRatio);
                Log.d("ImageUtil", String.format("Shrinking. maxRatio=%s",
                        maxRatio));

                // Create the bitmap from file
                BitmapFactory.Options options = new BitmapFactory.Options();
                options.inSampleSize = (int) maxRatio;
                srcBitmap = BitmapFactory.decodeStream(is, null, options);
            } else {
                Log.d("ImageUtil", String.format("No need for Shrinking. maxRatio=%s",
                        1));

                srcBitmap = BitmapFactory.decodeStream(is);
                Log.d("ImageUtil", String.format("Decoded bitmap successful"));
            }
            is.close();

        /*
         * if the orientation is not 0 (or -1, which means we don't know), we
         * have to do a rotation.
         */
            if (orientation > 0) {
                Matrix matrix = new Matrix();
                matrix.postRotate(orientation);

                srcBitmap = Bitmap.createBitmap(srcBitmap, 0, 0, srcBitmap.getWidth(),
                        srcBitmap.getHeight(), matrix, true);
            }

            return srcBitmap;
        }
