Android resources

A resource is additional static content used in an Android application.

Each type of resource goes under res/<type-dependent-folder-name>, ie:

AnAndroidProject/
    res/
        values/
            strings.xml
        drawable/
            graphic.png

String resources are saved under res/values/ and is accessed in app code using R.string, R.array and R.plurals.

The XML filename here is arbitrary, as each string resource defines its own resource ID.

xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="fruit">Apple 🍎</string>
</resources>

Then to use in code:

java

// "Apple 🍎"
String fruit = getString(R.string.fruit);
