We (the developer) are expected to resolve this conflict by either removing the resource (if it is a duplicate), renaming one of the instances or by moving one instance to a resource file with an appropriate qualifier. That is, there needs to be only one resolvable value for string/hello_world when referenced from the app module. In our app module we need to be able to resolve a unique resource for the combination of type, name and device configuration. The way resources work in Android starts to become apparent. /strings.xml: Error: Duplicate resources Execution failed for task ':app:mergeDebugResources'.
