java - How to stream music through multiple phones over bluetooth -

-

i'm trying connect android phones stream music.

the set this,

phone connected phone b.

phone b connected phone c.

a <--> b <--> c

i want stream music a through b c , hear on c.

i've looked a2dp (here) appears support 1 device @ time.

is there way stream using a2dp b , send c?

i'm trying come solution doesn't involve saving file a onto b , streaming using a2dp. file big , delay before playing should short.

are there ways stream file on , send stream b c using a2dp?

are there other streaming options on bluetooth? or other streaming classes try , use once data in b?

thanks

i found audiotrack class , think sort of solves problem.

i can send music file byte[] using bluetoothsocket , bluetoothserversocket classes across many phones need to.

once reach end phone create audiotrack object , write bytes , play music stream.

the limitation file must .wav file , of specific bit resolution, sample rate , channel set up. once decided on 1 wanted support converted files wanted use this website , streaming worked.

note: solution noisy. i'm looking how can fix that.

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
