            string path = GetPathToImage(data.Data);

            edit = prefs.Edit();
            edit.PutString("ProfilePicUri", uri.ToString());

    {
        ICursor cursor = ContentResolver.Query(contentURI, null, null, null, null);
        cursor.MoveToFirst();
        string documentId = cursor.GetString(0);
        documentId = documentId.Split(':')[1];
        cursor.Close();

        cursor = ContentResolver.Query(
        Android.Provider.MediaStore.Images.Media.ExternalContentUri,
        null, MediaStore.Images.Media.InterfaceConsts.Id + " = ? ", new[] { documentId }, null);
        cursor.MoveToFirst();
        string path = cursor.GetString(cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data));
        cursor.Close();

        return path;
    }
