You can use this simple static function, It is super easy to implement and reuse :)

public static Bitmap getBitmapFromBytes(byte[] bytes) {
        if (bytes != null) {
            return BitmapFactory.decodeByteArray(bytes, 0 ,bytes.length);
        }
        return null;
 }

This will work 

byte[] byteArray = DBcursor.getBlob(columnIndex);  

Bitmap bm = BitmapFactory.decodeByteArray(byteArray, 0 ,byteArray.length);
