public void playfm() {     uri myuri = uri.parse("http://108.166.161.206:8826/;stream.mp3");     try     {         if (mp == null) {             this.mp = new mediaplayer();         } else {             mp.stop();             mp.reset();         }         mp.setdatasource(this, myuri); // go initialized state         mp.setaudiostreamtype(audiomanager.stream_music);         streaming=true;         progress.setvisibility(view.visible);         stream.setvisibility(view.visible);         stop.setenabled(false);         mp.setonpreparedlistener(this);         mp.setonbufferingupdatelistener(this);          mp.setonerrorlistener(this);         mp.prepareasync();         log.d(tag, "loadclip done");     } catch (throwable t) {         log.d(tag, t.tostring());     } }
