资产经理，OpenFd? [英] Asset Manager, OpenFd?

问题描述

我的资产文件夹中有一个文件，我想通过以下方式进行访问:

I have a file in my assets folder I wish to access, I do so by:

AssetFileDescriptor fileSound = am.openFd("myfilepathetc/mymp3.mp3");

但是我得到了错误:

This file can not be opened as a file descriptor; it is probably compressed

经过一番谷歌搜索之后，似乎我需要向文件中添加扩展名，例如.mp3，因为Android会压缩资产文件夹中的内容，除非其格式已被压缩，唯一的问题是，我的文件已经是mp3而且它仍然无法打开.

After some googling it appears that I need to add an extension to my file, such as .mp3 as Android compresses stuff in the assets folder unless its of a format already compressed, the only problem is, my file is already an mp3 and it still wont open.

是否有不妥协的方法?还是有人有更好的方法从资产访问mp3，请注意，由于我不想打扰，我不想从原始文件夹访问它.

Is there a way of uncompromising it? Or does anyone have a better way to access an mp3 from assets, please note I do not want to access it from the raw folder for reasons i wont bother going into.

推荐答案

为什么不使用它:

private void playAudioSound() {
    try {
        AssetFileDescriptor afd = context.getAssets().openFd("sounds/jad0005a.wav");
        MediaPlayer player = new MediaPlayer();
        player.setDataSource(afd.getFileDescriptor());
        player.prepare();
        player.start();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
