                        .setAction("Action", null).show();

        public void onEndOfSpeech() {
            // TODO Auto-generated method stub

        }

        @Override //더 많은 소리를 받을 때

        }
    };


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

버튼을 클릭하면 음성인식이 시작되도록 하는걸 따라하고있는데

버튼을 누르고 로그캣을보니 bind to recgnition service faild 라고만 계속 뜨네요 ㅠㅠ

고수님들 좀 도와주세요
