java - Live Streaming of a music file in Android -


for learning purpose, tried creating client , server. 1 person sends udp packets of music file , other person receives it. created such app , packets being transmitted wanted. problem when after receiving packet, try play it, sound played nothing noise. meaningless sound comes speakers.

to test process of sending , receiving packets, tried replacing audio file text file , check contents of packets @ receiver side. noticed packets received highly random. mean not in correct order.

i know in udp packets can reach destination in order there no error control or anything. question how should correct sound out of speakers. if packets transmitted in order abc , received in order bca sound never correct. there way can convert byte array of packets meaningful sound.

i know one solution use tcp tcp not live streaming. for purposes live streaming , video conferencing, udp used. correct way gather , play received packets. appreciated.

code sender:

inputstream songinputstream = new fileinputstream("/sdcard/song.mp3"); byte[] buffer = new byte[1024];  try {     clientsocket = new datagramsocket(); } catch (socketexception e1) {     // todo auto-generated catch block     e1.printstacktrace(); } while ((songinputstream.read(buffer, 0, buffer.length)) > -1) {                      datagrampacket packet = new datagrampacket(buffer,                             buffer.length, hostinet, serverport);                     try {                         clientsocket.send(packet);                         log.e(tag, "packet sent "                                 + serviceinfo.getservicename().tostring());                     } catch (ioexception e) {                         // todo auto-generated catch block                         e.printstacktrace(); } 

code on receiver side:

byte[] buffer = new byte[1024]; datagrampacket packet = new datagrampacket(buffer, buffer.length); {             try {                 datagramsocket.receive(packet);                 log.e(tag,                         "recieved packet ip "                                 + packet.getaddress().tostring()                                 + " , port = "                                 + packet.getport()                                 );                  buffer = packet.getdata();                } catch (ioexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             } } while (true); 

now buffer contains packets sent sender not coming in correct order. how play sound using transmitted packets.
