Recording audio streaming in android without microphone -

i'm trying create app stream radio internet im using mediaplayer class , working fine.

i want add recording function app , use mediarecorder class seting

recorder.setaudiosource(mediarecorder.audiosource.mic); recorder.setoutputformat(mediarecorder.outputformat.mpeg_4); recorder.setaudioencoder(mediarecorder.audioencoder.amr_nb); 

but catch microphone sound. want record stream sound only.

what can ?

it's not possible record audio playback that.
it is possible audio data mediaplayer using visualizer api, audio of very low quality since it's intended visualizing purposes, doubt enough needs.

another alternative handle streaming in sort of proxy/relay server running within app, take audio data gets remote server , write file mediaplayer.
