推荐答案

默认下载位置是您在代码中设置的任何内容。您可以将文件写入几乎任何您想要的文件夹。



至于保护文件，你真的不能。没有办法阻止某人从手机上复制文件并共享它们。



唯一可以保护音频的方式（注意我没说文件 ！是指您以您设计的格式对音频进行编码，并且只能在您自己的播放器中进行解码和播放，以便了解它。这不是一件容易的事。祝你好运。

There default download location is whatever you set in your code. You can write the files to practically any folder you want.

As for protecting the files, you really can't. There is no way to stop someone from copying the files off the phone and sharing them.

The only way you can protect the audio (notice I did not say "files"!) is if you encode the audio in a format you devise and can only be decoded and played in your own player that is written to understand it. This is not trivial to do. Good luck with that.
