cc.audioEngine does not consider cc.loader.resPath on Android

[fleon]

• cocos2d-x version: 3.17
• devices test on: iOS, Android

Steps to Reproduce:

If I am using cc.loader.resPath, all files loaded by cc.loader are relative to that path, except for all audio (sfx and music) files on Android, in which case they are absolute. Because of that I have to use the below logic in my code:

// resPath is '1x', '2x', '3x' etc

function playEffect(name, repeat = false) {
  // todo: bug with android... takes absolute path instead of relative
  const dir = cc.sys.os === cc.sys.OS_ANDROID ? 'res' : '..'
  return cc.audioEngine.playEffect(`${dir}/sfx/${name}.wav`, repeat)
}

function playMusic(name, loop = false) {
  cc.audioEngine.stopMusic()

  // todo: bug with android... takes absolute path instead of relative
  const dir = cc.sys.os === cc.sys.OS_ANDROID ? 'res' : '..'
  cc.audioEngine.playMusic(`${dir}/music/${name}.mp3`, loop)
}

The above code is in JS, but the core issue lies in the C++ version of AudioEngine for Android.

cc.loader.resPath is not used for audios. https://github.com/plter/Cocos2d-x-js-3-docs/blob/master/Cocos2d-JS/Features/cc-loader/en.md#respath
