backgroundAudioManager 安卓系统无法触发onPlay、onPause和onStop，为什么？IOS和微信工具下是可以的，有人知道吗？bug？

//app.js

App({

    onLaunch: function () {

    var that = this;

    backgroundAudioManager.onPlay(function (res) {

    console.log(‘音乐打开’)

    that.globalData.isPlaying = true;

    })

    backgroundAudioManager.onPause(function (res) {

    console.log(‘音乐暂停’)

    that.globalData.isPlaying = false;

    })

})
