            @SuppressWarnings("deprecation")
            @Override
            public Cursor newCursor(SQLiteDatabase db, SQLiteCursorDriver masterQuery,
                    String editTable, SQLiteQuery query) {

                query.bindBlob(1, mac);



                if (Build.VERSION.SDK_INT < 11) {
                    return new SQLiteCursor(db, masterQuery, editTable, query);
                } else {
                    return new SQLiteCursor(masterQuery, editTable, query);
                }
            }
        }, query, null, DB_TABLE);

This is a design bug in the Android database API.

query and rawQuery accept only string parameters. execSQL accepts any Object parameters, but does not return results. SQLiteStatement accepts parameters of any type, but allows only queries that return a single value.

What you can do is to ignore parameters, and format the blobs as blob literals by hand:

cursor = db.rawQuery("SELECT a FROM b WHERE c = x'112233'", null);
