如何在android外部存储目录中创建一个文件夹? [英] how to create a folder in android External Storage Directory?

问题描述

我无法在 android 外部存储目录中创建文件夹.

I cannot create a folder in android External Storage Directory.

我在清单上添加了许可，

I have added permissing on manifest,

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

这是我的代码:

 String Path = Environment.getExternalStorageDirectory().getPath().toString()+ "/Shidhin/ShidhiImages";
  System.out.println("Path  : " +Path );
  File FPath = new File(Path);
  if (!FPath.exists()) {
        if (!FPath.mkdir()) {
            System.out.println("***Problem creating Image folder " +Path );
        }
  }

推荐答案

这样做:

String folder_main = "NewFolder";

File f = new File(Environment.getExternalStorageDirectory(), folder_main);
if (!f.exists()) {
    f.mkdirs();
}

如果您想在其中创建另一个文件夹:

If you wanna create another folder into that :

File f1 = new File(Environment.getExternalStorageDirectory() + "/" + folder_main, "product1");
if (!f1.exists()) {
    f1.mkdirs();
}
