How to Create a folder in external sdcard in Android 4.4.2(Kitkat) API level 19

Question

I try a lot to create a folder in SD card in android 4.4.2 version. i try the following code

 String dirName="Test";
   File file = new File(Environment.getExternalStorageDirectory(), dirName);
        boolean status = file.mkdir();
                    if (status)
                        Toast.makeText(MainActivity.this,
                                "Directory created successfully", Toast.LENGTH_SHORT)
                                .show();
                        else
                            Toast.makeText(MainActivity.this, "Directory create failed",
                                    Toast.LENGTH_SHORT).show();

but it creates a folder in internal storage.

and I try another code is

  String path=System.getenv("SECONDARY_STORAGE");
                File file=new File(path +"/Test123");
                file.mkdir();

'but it creates a folder in internal storage. '. Don't believe you. Please tell the value of 'file.getAbsolutePath()'. — greenapps, Oct 10 '15 at 08:21
file.getAbsolutePath() gives the path of External SDCard but it does not create a folder. — , Oct 10 '15 at 08:31

The documentation states that

Applications should not directly use this top-level directory, in order to avoid polluting the user's root namespace. Any files that are private to the application should be placed in a directory returned by Context.getExternalFilesDir, which the system will take care of deleting if the application is uninstalled.

where with top-level directory they mean the return value of Enviroment.getExternalStorageDirectory()

Using getExternalFilesDir you will have

 File file = new File (getExternalFilesDir(null), dirName);
 if (!file.exists()) {
   boolean status = file.mkdir();
   if (status) {
        Toast.makeText(MainActivity.this, "Directory created successfully", Toast.LENGTH_SHORT).show();
   } else {
        Toast.makeText(MainActivity.this, "Directory create failed", Toast.LENGTH_SHORT).show();
   }
 }

also you should be aware of the fact that mkdir() returns false if the directory already exists

It creates folder in our applications folder inside the internal storage. – Oct 10 '15 at 08:34
it does, and accordingly to the documentation, that is the folder you should use – Blackbelt Oct 10 '15 at 08:35
It creates a folder but inside internal storage. not in external sdcard. – Oct 12 '15 at 03:52
it creates a folder inside `/sdcard/Android/data` – Blackbelt Oct 12 '15 at 08:14
it creates a folder inside /sdcard/android/data/ – Oct 12 '15 at 09:08
yes exactly. Stick with that and pollute the sdcard's root – Blackbelt Oct 12 '15 at 09:09
we are not able to create the folder in root of sdcard. we can only create a folder in package name folder in android 4.4.2(kitkat). – Oct 12 '15 at 09:12

This should be self-explanatory.

String folderName = "NewFolder";

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

Make sure you have added WRITE_EXTERNAL_STORAGE permission in your manifest.

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

You posted the same code as OP did. And even without checking results. So what does that help? – greenapps Oct 10 '15 at 08:19
Already used this bit of code @greenapps. Already works. Edited to give proper credit. – Aloha Oct 10 '15 at 08:19
I already added this permission in mwnifest file. but it does not create a folder in android 4.4.2 – Oct 10 '15 at 08:28
