How to create directory in external storage?

I want to create a directory in external storage but I am unable to create it.

This is my code:

 String path = Environment.getExternalStorageDirectory().toString();
    File dir = new File(path,"/appname/media/appimages/");
    if (!dir.isDirectory()) {
        dir.mkdirs();
    }

    File file = new File(dir, "image" + ".jpg");
    String imagePath =  file.getAbsolutePath();
    //scan the image so show up in album
    MediaScannerConnection.scanFile(this,
            new String[] { imagePath }, null,
            new MediaScannerConnection.OnScanCompletedListener() {
                public void onScanCompleted(String path, Uri uri) {

                }
            });


    File file1 = new File(Environment.getExternalStorageDirectory().getPath() + "/MeaVita");

    file1.mkdir();


    //  imageRoot.mkdirs();

    Log.d("directory",dir.getAbsolutePath().toString());

I tried both using mkdirs() and mkdir(). But neither of them work. I am unable to see the folder at the path storage/emulated/0/ .

I am running this on android 23.0 onwards also I have added the permissions. 

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

Does someone know what goes wrong in my code?

Thanks in advance.

I checked it .. Its a permission issue .. quick solution to switch to 22 instead of 23. or you need to handle permissions on runtime see : link

With certain permissions you need to check at runtime if the users accepts them you can do it by creating a method like this: 

private void checkFilePermissions() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        int hasWriteExternalStoragePermission = checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE);
        if (hasWriteExternalStoragePermission != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                    REQUEST_CODE_ASK_PERMISSIONS);
        }
    }
}

And then use it before you access your storage
