android - 下载文件时如何设置手机内存路径？

Question

I am developing an Android application that can download .mp3 files. The path i set for downloading files is "/sdcard/downloadedfile.mp3". It is going to sdcard

.我想设置设备内部存储器的路径。所以没有 sdcard 的设备应该默认进入内部存储器..

谁能帮我找到一个解决方案..>？

我想你可以试试这个:

String fileName="name.mp3";
File folder = new File(Environment.getExternalStorageDirectory().getPath() + "/floderName/");

if (!folder.exists()) {
    try {
        folder.mkdirs();
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println("Default Save Path Creation Error:" + folder);
    }
}

File logFile = new File(folder, fileName);
if (!logFile.exists()) {
    try {
        logFile.createNewFile();
    } catch (IOException e) {
        e.printStackTrace();
        System.out.println("Default Save Path Creation Error:" + logFile);

    }
}

顺便说一下，请不要忘记在android6.0上添加权限和运行时权限
