Nexus 5 not creating directory

When I run the code at the end of the video, I get the error "Failed to create directory."

// Get the URI

            // 1. Get external storage directory
            String appName = MainActivity.this.getString(R.string.app_name);
            File mediaStorageDir = new File(

            // 2. Create our subdirectory
            if (! mediaStorageDir.exists()) {
                if (! mediaStorageDir.mkdirs()) {
                    Log.e(TAG, "Failed to create directory.");
                    return null;

I'm sorry, I had copied something differently and changed it. It works fine now.

The code in the video works on my Nexus 5, but I'll take a look at what you've posted and see if I can troubleshoot anything.
