注意事项

1、 在安卓系统如果当前app存储位置在MEDIA_MOUNTED(SD卡)，音频文件会被存储到”外部存储路径”+”/”目录下，否则存在”/data/data/app包名”+”/”目录下,文件名需要自己定义。在IOS系统中，录音文件名只支持wav格式，写成其它格式会报错，文件名可以写成全路径也可以只写文件名，插件自动补全路径。全路径为该应用下的”documents/tmp”。也可用使用cordova的file插件将目录写成cordova.file.LocalFileSystem.TEMPORARY。需要注意的是指定的路径在开始录音之前必须存在，否则会引发异常报错。
2、 播放音频文件之前要先加载文件路径。
3、 本文实例所用的demo在\model\UI2\demo\native\audio目录下，可以自行打包查看效果。
