As the image below shows, the application is not too complicated.
The two buttons will each create a new thread to send and recv audio data respectively. And the sender will read audio data from the file /data/1.wav. Then, it sends the data to udp port 2048 on localhost. The receiver reads on 2048 port and feed data received to AudioTrack object.

hw do i get full duplex in this??
To achieve full duplex, start receiver and sender threads on each peer simultaneously.
so instead f buttons n on click n dn calling - all i do is call both the func send and receive together rite??
in dis fr prog 2 run do v need 2 do port forwarding also?? or jus run d code on 2 wifi conn machines ??
no need to set up port forwarding if these two devices are in the same lan.
my log cat shows byt_count but d receiving end aint playing d audio i hav sent from my sd card.. so isnt any ip addr required for directing d audio towards d odr end...

I tried to contact you but couldn't.
Anyway,
I am looking for a player which can play UDP and RTSP stream on android 2.2 platform.
Could u please help me regarding this?
Plase respond positively, Crossing my fingers and hoping for the best...
Thanks
I get a url multicast (udp, rtmp, mms..) (like IPTV)
Can I stream it on android ?
Please help.
Hello,
I have understood that the audio data is PCM. I can compress the audio before sending via UDP?.
Yes, it's definitely possible. Just decode it at the receiving end before play a sample.
Thank you so much. This works for me locally. However, when I tested it over the internet (using external/public ip) I have to do port forwarding. I am about to distribute the apk for testing purposes and I don't want to require each of them to manually do port forwarding. How can this be done without port forwarding?
How can I download the streaming audio project folder and import to my android ADT? thanks!
how can i send voice stream from one android device to multiple android device via server??can u plz give me any reference or link??
I am trying on same phone, it just giving me noise.
I mean started receiving thread and then I started streaming thread.
It receives packets but only noise is coming not actual audio.
Please help.
I cant stop this thread and I dont know why.
When I send again, it overlap with the previous.
Can anyone solve my problem?
Thanks for your help
