/**
 * The StringProvider interface exposes an abstract method of translating strings from the OpacApi
 * classes. Since version 3.2.1, it is highly discouraged to hardcode any string into the OpacApi
 * implementations which might be displayed to the user, as this makes internationalization very
 * hard.
 *
 * While Android has a powerful i18n library using the 'string resources' concept, our apis.*
 * subpackage should not depend on Android, to make it seperable from the app, e.g. for running our
 * test suite on a PC. Therefore, this abstract interface provides access to Android's i18n API on
 * Android devices. It currently performs a no-op on other devices.
