mediaTimer = setInterval(function() {

推荐答案
当我在浏览器中打开链接时，提供播放声音的链接无法正常工作。我不能播放声音。
The link u r providing for playing sound is not working properly when I am opening the link in a browser I m not able to play sound.
因此，请将ur rockGuitar.mp3存储在assets / www文件夹中，并在播放该文件时提供文件的src为
So kindly store ur rockGuitar.mp3 inside your assets/www folder and while playing that file provide the src of the file as
src= "/android_asset/www/rockGuitar.mp3";
newMedia= new Media(src,onSuccess1,onError);
或在声音src中提供工作链接。
Or provide working link in the src of sound.
