Answer 1

This works well;

public class ExifUtils {

public static Bitmap getRotatedBitmap(Context context, Uri uri) {
    try {
        Bitmap bitmap = MediaStore.Images.Media.getBitmap(context.getContentResolver(), uri);
        float width = (float) bitmap.getWidth();
        float height = (float) bitmap.getHeight();
        float max = Math.max(width / 1280.0f, height / 1280.0f);
        if (max > 1.0f) {
            bitmap = Bitmap.createScaledBitmap(bitmap, (int) (width / max), (int) (height / max), false);
        }
        Bitmap rotateBitmap = rotateBitmap(bitmap,
                new ExifInterface(context.getContentResolver().openInputStream(uri))
                        .getAttributeInt(ExifInterface.TAG_ORIENTATION, 1));
        if (rotateBitmap != bitmap) {
            bitmap.recycle();
        }
        return rotateBitmap;
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
}

private static Bitmap rotateBitmap(Bitmap bitmap, int i) {
    Matrix matrix = new Matrix();
    switch (i) {
        case 2:
            matrix.setScale(-1.0f, 1.0f);
            break;
        case 3:
            matrix.setRotate(180.0f);
            break;
        case 4:
            matrix.setRotate(180.0f);
            matrix.postScale(-1.0f, 1.0f);
            break;
        case 5:
            matrix.setRotate(90.0f);
            matrix.postScale(-1.0f, 1.0f);
            break;
        case 6:
            matrix.setRotate(90.0f);
            break;
        case 7:
            matrix.setRotate(-90.0f);
            matrix.postScale(-1.0f, 1.0f);
            break;
        case 8:
            matrix.setRotate(-90.0f);
            break;
        default:
            return bitmap;
    }
    try {
        Bitmap createBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, false);
        bitmap.recycle();
        return createBitmap;
    } catch (OutOfMemoryError e) {
        e.printStackTrace();
        return null;
    }
  }
