How to make own Reciver

[pkopec95]

Hello, i have question how to make own data reciver.
In Library we have:
` private class ConnectedThread extends Thread {
private final BluetoothSocket mmSocket;
private final InputStream mmInStream;
private final OutputStream mmOutStream;

    public ConnectedThread(BluetoothSocket socket, String socketType) {
        mmSocket = socket;
        InputStream tmpIn = null;
        OutputStream tmpOut = null;

        // Get the BluetoothSocket input and output streams
        try {
            tmpIn = socket.getInputStream();
            tmpOut = socket.getOutputStream();
        } catch (IOException e) { }

        mmInStream = tmpIn;
        mmOutStream = tmpOut;
    }

    public void run() {
        byte[] buffer;
        ArrayList<Integer> arr_byte = new ArrayList<Integer>();

        // Keep listening to the InputStream while connected
        while (true) {
            try {
                int data = mmInStream.read();
                if(data == 0x0A) {
                } else if(data == 0x0D) {
                    buffer = new byte[arr_byte.size()];
                    for(int i = 0 ; i < arr_byte.size() ; i++) {
                        buffer[i] = arr_byte.get(i).byteValue();
                    }
                    // Send the obtained bytes to the UI Activity
                    arr_byte = new ArrayList<Integer>();
                } else {
                    arr_byte.add(data);
                }
            } catch (IOException e) {
                break;
            }
        }
    }}`

And I want to make this but with my conditions. For example if two last bytes is 0x0D.
Could u help me?
