udp socket 통신에 구글 protocol buffer를 적용

Question

byte[] data = new byte[1024];
outPacket = new DatagramPacket(data, data.length, serverAddr, serverPort);
inPacket = new DatagramPacket(data, len);
dSock.send(outPacket);
dSock.receive(inPacekt);
byte[] resultBuffer = new byte[inPacket.getLength()];

System.arraycopy(inPacket.getData(), 0, resultBuffer, 0, inPacket.getLength());


parseFrom(resultBuffer).toBuilder();

 

inPacket이 잘리는 건지 뭔지

PacketClass.parseFrom(resultBuffer).toBuilder(); 를 하면

InvalidProtocolBufferException이 발생합니다

com.google.protobuf.InvalidProtocolBufferException: Protocol message contained an invalid tag (zero).

어떻게 해결해야 될까요
