考虑像这样使用一个 Android's default external storage folders, in your case the DIRECTORY_MUSIC

File path = Environment.getExternalStoragePublicDirectory(
    Environment.DIRECTORY_MUSIC);

您可以使用此 File class constructor 在 SD 卡上创建一个新文件夹：

File audioFolder = new File(Environment.getExternalStorageDirectory(), 
    "newaudiofolder")
if (!audioFolder.exists()) {
    boolean success = audioFolder.mkdir()
    if (success) {
        // save the file 
    }
}
