The XML resource files containing localized strings are placed in subfolders of the project's res folder.
A string resource provides text strings for your application with optional text styling and formatting. There are three types of resources that can provide your application with strings: String. XML resource that provides a single string.
A string constant is an arbitrary sequence of characters that are enclosed in single quotation marks (' '). For example, 'This is a string'. You can embed single quotation marks in strings by typing two adjacent single quotation marks.
Try context.getResources().getString(R.string.app_version) where 'context' is your Activity or Application instance.
If your question is really about getting the version name of your application there is a better way:
String versionName = getPackageManager().getPackageInfo(getPackageName(), 0).versionName;
This way you retrieve the info directly from the AndroidManifest and you don't have to maintain it twice.

In Java: R.string.string_name
In XML:@string/string_name
R.string.app_version or @string/app_version taken from strings.xml is your constant and will always represent the value you entered into that XML file.
