Question: I got a question about the "Androidmanifest.xml".
The default settings of the installation of an application is that
the application have permission to the SD-card and Telephone Calls.

How can I set that the application has only access to the SD-card and not to the Telephone Calls what is set as default?

Answer: 
Unfortunately, customizing the section index is not possible using the public APIs.

You'll probably end up creating a custom section index view if this feature so important for your app.
Refer to this answer: 

[Custom UITableView section index](https://stackoverflow.com/questions/5987399/custom-uitableview-section-index)

I think it is really tough or next to impossible to customize section index or create custom section index.

Let me know if you need more help.

Hope this helps.
