Why the folder is not created in the internal storage of some android devices?

I have created a folder in the internal storage for storing files. But the issue is the folder is not created in some Android devices. The folder is created in lollipop devices but not in oreo and nougat.

The code for creating a folder in internal storage

File f1 = new File(Environment.getExternalStorageDirectory(), Constants.STORED_FOLDER);
if (!f1.exists()) {
  f1.mkdirs();
}
Log.e("check_path", "" + f1.getAbsolutePath());

Also, I have another query on how to make the folder visible in the gallery.

It is not visible in the gallery? How to solve this issue?

For show up your folder immediately, you need to send a broadcast

sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
        Uri.parse("file://"
                + Environment.getExternalStorageDirectory())));

this code will tell the gallery app that something has been added so please rescan for media now

Since Android 6.0 (If my memory right), many permissions needs to be assigned dynamically (at runtime). You need to get your permission at runtime.

Is there any additional permission is needed for higher level API?

The basic permissions are WRITE_EXTERNAL_STORAGE, but you not only needs to declare it in AndroidManifest.xml, but also at runtime.

Also I have another query how to make the folder visible in gallery. It is not visible in gallery? How to solve these issue?

If you mean the photo gallery, you may need to wait for the media process to scan the whole sdcard to get your folder (which must contain some photos) added in gallery.
