hello evry one

i’m developping an integrated application using Gear2 and android and i used the voice Recorder Sample to record voice

the probleme is that the recording voice can be executed only one time

when i navigate from the voice recoding page to another page using window.location.href=”” , the audio control will be closed. i don’t know how because when i go back to the voice recoding page i get this error when i push the recording button  (js/models/audio.js (187) :TypeError: ‘null’ is not an object (evaluating ‘audioControl.recorder’) ) and of course these two errors before(

js/models/audio.js (48) :[object CameraError]
js/views/main.js (285) :onAudioError())

pleaase help i want to have the possibilty to record voice and navigate between html page . 

help pleaase
