Resources can be added for a specific product flavor.
For this example, assume that we have already defined two product flavors called free and paid. In order to add product flavor-specific resources, we create additional resource folders alongside the main/res folder, which we can then add resources to like usual. For this example, we'll define a string, status, for each product flavor:
/src/main/res/values/strings.xml
<resources>
<string name="status">Default</string>
</resources>
/src/free/res/values/strings.xml
<resources>
<string name="status">Free</string>
</resources>
/src/paid/res/values/strings.xml
<resources>
<string name="status">Paid</string>
</resources>
The product flavor-specific status strings will override the value for status in the main flavor.
