I need android.permission.WRITE_EXTERNAL_STORAGE declared in manifest of an app I'm developing. Is there a way to explain to a user why I need this permission at install (optimal) or at run time? So when app is installed something like "This permission is needed to use custom levels" is displayed? I need external, not application directory write permission.

AFAIK, your only option is to use a privacy policy page that explicitly states what each dangerous permission in the app is used for.

You cannot change the default permissions dialog box (Look here).

However, you can have a dialog box pop up just before user gives permission for the first time. In the dialog box you can have the content you want with two button continue and cancel. When user selects continue then you can let default permission dialog box pop-up.

But as said by DaveNOTDavid this is not the best practice. As a hobbyist it is alright otherwise mention it in the Terms and Condition or Privacy Policy, as mentioned above.

Edit: I was reading the Documentation and found this. It might be helpful for version 23.0.0 and above.
