Localization sample (using Dialogflow) in Java

Actions on Google: Number Genie Sample

⚠️ Warning: Conversational Actions will be deprecated on June 13, 2023. For more information, see Conversational Actions Sunset.

This sample demonstrates Actions on Google features for use on Google Assistant, including how to steer conversation in a numeric guessing game through the use of localization (French and English), deep links, fallbacks, contexts, alongside rich responses -- using the Java client library and deployed on App Engine.

This Action uses the i18n-node library to provide responses in both French and English, which are listed in the locales directory. In each function execution, the strings.js setLocale() function is called to set the i18n-node locale based on the user locale in the incoming request. Prompts are then selected by i18n-node from the available languages, defaulting to en if the user's language is unavailable.

⚠️ This code sample was built using Dialogflow. We now recommend using Actions Builder or the Actions SDK to develop, test, and deploy Conversational Actions.
