What is the process to modify the default language of an Android application?

edit

To modify the default language of an Android application, follow these steps:

1. Open your Android Studio project.

2. Right-click on the res folder, then select New > Android Resource Directory.

3. Select "values" as the resource type and "language code" (e.g. "en" for English, "es" for Spanish) as the resource name. Click OK.

4. In the newly created values-language code directory, right-click and select New > Values Resource File. Name the file "strings.xml".

5. Open the newly created "strings.xml" file and add the translated strings. For example, if you're translating to Spanish, you would provide the Spanish translation for each of the English strings.

6. Repeat steps 3-5 for each language you want to support.

7. In the AndroidManifest.xml file, add the following code to the application tag: android:configChanges="locale".

8. In your activities, override the attachBaseContext() method and add the following code:

Configuration configuration = new Configuration(); configuration.setLocale(new Locale("language_code")); context = context.createConfigurationContext(configuration);

Make sure to replace "language_code" with the appropriate language code for each activity.

1. Build and run the application.

2. To test the language change, go to Settings > Language & input > Language and select the language you added to the app.
