Typically this file will be called "strings.xml", and must be placed in the values directory:

MyApp/res/values/strings.xml

The strings can now be retrieved by your application through the symbol specified in the "id" attribute:

public class MyActivity extends Activity
{
    public void onStart() 
    {
        super.onStart();

        String back = getResources().getString(R.string.back).toString();
        back = getString(R.string.back).toString();  // synonym
    }
}

Unlike system resources, the resource symbol (the R class) we are using here comes from our own application's package, not android.R.

Note that the "mainLabel" string is complex, including style information. To support this, the getString() method returns a CharSequence object that you can pass to a TextView to retain those style. This is why code must call toString() on the returned resource if it wants a raw string.
