android - 在Android中获取辅助外部存储设备的公共(public)/根目录？

Question

在 android 中，我可以使用以下方法获取手机的可移动外部存储:

for (File f : context.getExternalFilesDirs("/")) 
    if (Environment.isExternalStorageRemovable(f))
        Log.println(Log.DEBUG, "#", f.getAbsolutePath());

但是，这返回 /storage/8E6A-06FF/Android/data/test.application/files 这不是我想要的，因为我只想要可移动的根路径 /storage/8E6A-06FF/。如何获取手机移动存储的根路径？

你可以试试这个，它对我来说非常有用。它对所有操作系统版本都非常有用。到目前为止，我没有发现这个功能有任何问题。

public static String getSDPath() {
    String filepath = "";
    String[] strPath = {"/storage/sdcard1", "/storage/extsdcard",
            "/storage/sdcard0/external_sdcard", "/mnt/extsdcard",
            "/mnt/sdcard/external_sd", "/mnt/external_sd",
            "/mnt/media_rw/sdcard1", "/removable/microsd", "/mnt/emmc",
            "/storage/external_SD", "/storage/ext_sd",
            "/storage/removable/sdcard1", "/data/sdext", "/data/sdext2",
            "/data/sdext3", "/data/sdext4", "/emmc", "/sdcard/sd",
            "/mnt/sdcard/bpemmctest", "/mnt/sdcard/_ExternalSD",
            "/mnt/sdcard-ext", "/mnt/Removable/MicroSD",
            "/Removable/MicroSD", "/mnt/external1", "/mnt/extSdCard",
            "/mnt/extsd", "/mnt/usb_storage", "/mnt/extSdCard",
            "/mnt/UsbDriveA", "/mnt/UsbDriveB"};

    for (String value : strPath) {
        File f = null;
        f = new File(value);
        if (f.exists() && f.isDirectory()) {
            filepath = value;
            break;
        }
    }
    return filepath;
}
