            headerOut.writeInt(mCurrentBlobVersion);
            DeflaterOutputStream out = new DeflaterOutputStream(sink);
            out.write(data);
            // finishes and commits the compression run
            out.close();
            result = sink.toByteArray();
            if (DEBUG) {
                Log.v(TAG, "Deflated " + data.length + " bytes to " + result.length);
