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);
}

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.
