Example of Localization in React Native Multi Language App

Here is an Example of Localization in React Native Multi Language App. Localization is the process of making something local in character or restricting it to a particular place. In case of application development, it is related to the development of the application according to the local language. Many of us build the applications for others which sometimes requires localization so let’s get started with the Example of Example of Localization. To do the localization we are going to use LocalizedStrings component from react-native-localization library.

How to Use

Here is the code snippet of LocalizedStrings we have used in this Example.

In this example below, we will make a Home screen to select the language and will show the Text content on the next screen accordingly from a common string repository where we have defined same text for each language code.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App.

Assuming that you have node installed, you can use npm to install the react-native-cli command line utility.
Open the terminal and go to the workspace and run Run the following commands to create a new React Native project This will make a project structure with an index file named App.js in your project directory.

Installation of Dependencies

To use LocalizedStrings we need to install react-native-localization package. To install this

Open the terminal and jump into your project

Run the following command

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module the directory named react-native-localization.

We are also going to use React Navigation to Switch the activities so we need to install react-navigation using

Linking of Library

To use react-native-localization library we have to link some dependencies in Android and IOS project files. In order to link the library you have to run following command:

You can see the following changes in your android project. If you are unable to find the changes then please do those changes as they are must for this example.

Go to the MultiLangExample> android > app > build.gradle.
Scroll down and you can see the following dependency and if not please add this.

Open MultiLangExample> android > settings.gradle and you can see the following lines and if not please add this.

 

Open MultiLangExample> android > app > src > main > java > com > multilangexample> MainApplication.java  and you can see the following lines in imports if not then please add

Scroll down and you can see the following line in getPackages after new MainReactPackage() if not then please add a comma(,) and add

 

Here we have done with our installation of the library. If you are still facing the trouble please comment below so that we can help you out from the problem.

Common Problem

You can face the following problem

To solve that issue update node_module > react-native-localizaion>android>build.gradle with the following code

You can download the source code from Github

OR

Follow the steps below

We are using the following project structure. So please make the following project structure and replace the code.

App.js

LanguageSelectionScreen.js

ContentScreen.js

stringsoflanguages.js

To Run the React Native App

Open the terminal again and jump into your project using. To run the project on an Android Virtual Device or on real debugging device or on the iOS Simulator by running

                

This is how you can make a multi-language React Native Application (Localization). If you have any doubt or you want to share something about the topic you can comment below or contact us here. There will be more posts coming soon. Stay tuned!
