Issue
Seekbar를 다루고있는 Thread에서
ui를 업데이트 하기위해 handler을 사용할 때, 너무 늦게 ui가 업데이트 되는 문제 발생

UI를 다루는 Thread runOnUiThread()

    val tt = object : TimerTask() {
        override fun run() {
            runOnUiThread {
                playTime = String.format(
                    "%02d:%02d",
                    ((mediaPlayer.getCurrentPosition() / 1000) % 3600 / 60),
                    ((mediaPlayer.getCurrentPosition() / 1000) % 3600 % 60)
                )

                tv_main_player_duration_time.setText(playTime)
                seekbar.setProgress(mediaPlayer.getCurrentPosition())
            }
        }
    }
