the toast parts never runs

[Ron McLeod]

I just ran your code and got Toast for clicks on both start and stop buttons. Do the ids in the layout file agree with the those in the code?

[Ryan flech]

my mistake. it is working. but now my problem is the whole code is not working or i can't work with it because i don't have two android phone.will you help me with??

my App is voice chat.you push on "start reciving" button in phone X then in phone Y put the Ip address in the textview and push start button.so you can talk to each other (phone X talks to phone Y)

you have to do it over the Wifi.

Unrelated to your problem - you might want to look at using AudioStream for this type of application - it takes care of the networking/scheduling/de-jittering/concealment/etc for you.
