Android上的Javascript音频播放静音 [英] Javascript audio play muted on Android

问题描述

我想播放mp3声音，当事件发生时我正在使用以下代码：

I want to play an mp3 sound, when an event occurs and I am using the following piece of code:

var audio = new Audio('coins.mp3');
audio.play();

它在Chrome浏览器的Windows下工作得很好，但是如果我在我的4.4 Android上打开它，它会被静音。我测试了另一个Android版本（2.3，而不是Chrome），它正在运行。如果我从4.4 Android上的onClick事件调用代码，它似乎也有效。

It works great under windows in Chrome, however if I open it on my 4.4 Android, it is muted. I tested on another android version (2.3, not Chrome) and it was working. It seems it is also working if I call the code from an onClick event on 4.4 Android.

任何人都可以为我解释这个行为，因为我找不到答案经过几个小时的谷歌搜索。 :(

Can anyone please explain this behaviour for me, as I can not find the answer after some hours of googling. :(

提前致谢！

推荐答案

这是链接到谷歌Android漏洞，因为Android中缺少对AUDIO标签的支持。

由于编解码器许可问题和操作系统实施/支持，HTML5音频支持在不同设备/操作系统之间并不一致。如果你只是在播放MP3文件，你可以通过使用PhoneGap的 Media 课程，将在所有平台上提供一致且可靠的音频编程。

HTML5 Audio support is not consistent across different devices/OSes due to codec licensing issues and OS implementation/support. If you are just playing MP3 files, you can reliably handle those by using PhoneGap's Media class, which will provide consistent and reliable audio programming on all platforms.
