Android 7.0 (API Level 24) provides support for multilingual users, allowing users to select multiple locales in the setting. The locale object budget represents a specific geographic, political, or cultural area.<\/p>

Operations that require this locale to perform a task are called locale-sensitive and use that locale to generate information for the user.<\/p>

Step 1: Create A New Project & Create Resource Files<\/h2>

To create a new project in Android Studio.<\/p>

In this step, we need to create a string resource file for the Gujarati language.Go to app > res > values > right-click > New > Value Resource File and name it as strings.<\/p>

Now, we have to select the qualifier as a locale from the available list and select the language as Gujarati from the drop-down list. Below is a picture of the steps.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t
\n\t\t\t\t\t\t\t

Now, in this resource file, strings.xml(gu-rlN) add the code given below.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
