React Active for Android: How to build a cross-platform React Native app

The era of React Native apps

Have you got an idea on how useful React Native can be when you want to build cross-platform app development? Give a pat on your back. You are on the right track.

It is extremely simple to build an app with React Native. The overall look resembles any native iOS or android in its aesthetic appearance and performance. In comparison to other cross-platform app development platforms like Cordova cannot pose a great impact on your app development processes like React Native does.

Relying on the best Mobile app development company is a must for smoother Android app development and iOS app development processes.

Let’s get into the basic model of information on ReactNative app development first.
You might be quite familiar with these if you have gone through the official documentation of React Native and React. It would provide everyone with the right knowledge to keep moving in the right direction.

These are the few factors about React Native you might be knowing in advance:

  • React leverages state and props while wanting to pass different data via the application.
  • The data would only travel through a single direction.
  • The passed data in props would not be mutable.

As for React Native, these are the terms you should be familiar with:

  • Action
  • Reducer
  • Stateful Component
  • Stateless Component
  • Store

Set up the project

While you start any project, you need to remember a few universal rules:

  • Understand more about the tasks you need in the application.
  • Organise all the files in a proper manner.
  • Follow the right guidelines and particular coding conventions.

These are the things you need to consider for React Native:

  • Leverage a single top container to pass data to different containers.
  • Figure out an easier way of screen transition.
  • Manage all your application forms easily.

Understand what values you would be passing at different locations easily. This will help you out to debug in a better way.

Divide the task

You might need to assign various tasks that every application section would cover. With respect to React Native, you might need the following tasks for division:

Containers: These are those stateful React Native components dealing with data such as making server calls, passing the data to different components and setting local state. Hence they have their job limitations to access and distribution of data.

Components: All these stateless components would deal with the data visualisation. Their task would involve reorganisation and omission of data while building the UI app. We pass the data and callbacks to them through containers.

Actions: Their task involves the passage of data to various reducers to update the store. This is where we store every application data. You might include a few fetch requests to call specific APIs, pass appropriate data and get the right response. This can also include a few custom data which we need to pass to different reducers.

Reducers: They can listen to every action emitted. They also have the privilege to update every store with every data you receive.

Store: This is where every data would live.

These would be the set of major tasks of any application in React Native. You need to keep all these tasks independent in order to keep it organised. This quantity of boilerplate would be necessary to keep everything clean. You can organise every other file which might simplify your task. These are the files you need:

Helper functions- You need them inside your code to refactor to a different helper directory.

Application fixed values- It can remain constant through the entire application. You can also refactor it to default values directory.

Take a note on the structure of the project

All you need to do next is to set up your project structure. You can apply them over here for small and midsize projects. You also have the privilege to create commonplace for reducers, actions, containers and components. With this setup, you can track all similar functions:



  1. Import/export your code

While an application would grow larger, you would have difficulties to track every functionality of certain component across various directories. While dealing with a large application, use every component as your module. With such a setup, you have the freedom to import/export any kind of reusable code which you might have already laid your hands on. Then you just have to copy the entire module into your new application


After the initial setup, you just need to follow these steps:

Install Node.js. Install them using this create-react-native-app command line utility when you open a new terminal window and run the command given

Next step would be to run this command:

Navigate to the folder via your command line. Start your development server.

Open the App.js file with the help of a code editor.

02. Run your app

Leverage Expo client app for application testing. Scan your QR code inside your terminal. Leverage the Android simulator in case you have Android Studio installed.


03. Create a basic login

Create a test login by typing the following to add the sample text to your app:


It is important to work with styles which might match up with CSS. While you need to add a style to the text you created, you can edit the text line to:

You can add the text style using this command:

04. Set up Firebase and NativeBase


You might have to install three more libraries called Firebase, NativeBase and React Native Dialog Input. All you need to do next is to navigate your project folder by leveraging this command line.

Import the Firebase, React Native Dialog Input and NativeBase at the App.js file.

Setup the firebase configuration by using this command:

05. Build the container


To build the container, you might have to remove your <View> section which would be placed automatically by React while you create the project. You can also replace it using the container while you set up your login form containing the input field and the label for the email id and password. With three buttons, you can configure everything. You just have to use this text:

Once all this is done, ensure that you set up the events, create a sign-up function and login function, signup function and forgot password function.

To sum it up


Creating a React Native code is the right choice for every business since it would pose a lot of business value as well. You can impress your customer with the speed and simplicity of the app functioning.
