For quick string references, like a global string, you should try and use the string resource. You can set a string resource by opening the file in your project explorer located at
values/strings.xml. In this file is where we will define our strings.
To manually enter a string (assuming your in Eclipse) double click the
values/strings.xml file, when the new window opens at the bottom select "strings.xml". In here you can add your own strings in the following format:
<string name="{a_name_here}">{you put the string's value in here}</string>
for example, I could store a URL for later use, it would look something like..
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_url_1">http://google.com/</string>
</resource>
We can reference that string in our code like this:
String s = getString(R.string.app_url_1);
