Question

I was learning how to connect to the internet by readiing a book, and in the first line of the example given was the following:

String myFeed = getString(R.string.my_feed);

I’m still learning how to connect to the internet but I could not understand what does R.string.my_feed means, and the author has not given any clue how my_feed is defined.

Now my question is, how to define my_feed? Should I create a folder named string and inside it write the website I want to have access to or what?

Answer 1

There is an XML file reserved for defining custom strings, it is in res/values/strings.xml. If strings.xml doesn’t exist, create it with the following content:

<?xml version="1.0" encoding="utf-8"?>
<resources>    
  <string name="my_feed">http://myfeed.com</string>
</resources>

Then you can access it using

String myFeed = R.string.my_feed;  // (it becomes a static final property)
