Answer 1

You should Use This Permission in your mainfest file.

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

Answer 2

I'm not sure just try to create folder like below -

success = myFolder.mkdirs();

instead of

success = myFolder.mkdir();

as per mkdirs() And, don't forget to add the below permisstion into your manifest file.

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