Getting started with React Native and Redux

This article is a simple step-by-step of how to start a project with React Native and Redux.

Source Code (Branch init)

Create-react-native-app

Following the path of its excellent web brother, I recommend the use of the create-react-native-app to bootstrap your new project. This one configures all the build tools necessary to create a React Native app, and gives you some excellent Expo integrations.

First thing to do is to install CLI tool with

npm install -g create-react-native-app

Now, run the following command with the name you want to give to your project

react-native init my_awesome_app

Go forward to the new folder, and run

react-native run-android

Announcing the Ionic React Beta

How to Get Started with React & Ionic?

Getting started is quite simple. Begin first with create-react-app, because we want you to use Ionic with React in the most familiar way. We also recommend using TypeScript in your app, something we recently wrote about on our blog if you need tips. While this is not required, we mention it because Ionic React ships with TypeScript type definitions, and it makes for an excellent developer experience.

 npx create-react-app my-ionic-app --typescript
 cd my-ionic-app

Unstructured Supplementary Service Data (USSD)

Unstructured Supplementary Service Data (USSD), sometimes referred to as "Quick Codes" or "Feature codes", is a communications protocol used by GSM cellular telephones to communicate with the mobile network operator's computers. USSD can be used for WAPbrowsing, prepaid callback service, mobile-money services, location-based content services, menu-based information services, and as part of configuring the phone on the network.^[1]

USSD messages are up to 182 alphanumeric characters long. Unlike Short Message Service (SMS) messages, USSD messages create a real-time connection during a USSD session. The connection remains open, allowing a two-way exchange of a sequence of data. This makes USSD more responsive than services that use SMS.^[1]  (extract from Unstructured Supplementary Service Data).

Install and build your first React Native app

React Native lets you build mobile apps using only JavaScript. With React Native, you don't build a "mobile web app", an "HTML5 app", or a "hybrid app". You build a real mobile app that's indistinguishable from an app built using Objective-C or Java. React Native uses the same fundamental UI building blocks as regular iOS and Android apps. You just put those building blocks together using JavaScript and React. React Native lets you build your app faster. Instead of recompiling, you can reload your app instantly. With Hot Reloading, you can even run new code while retaining your application state

What are five differences between React.js and React Native?

Reactjs is front end library developed by Facebook. It's used for handling view layer for web and mobile apps. ReactJS allows us to create reusable UI components. It is currently one of the most popular JavaScript libraries and it has strong foundation and large community behind it.

React Nativeis a mobile framework that compiles to native app components, allowing you to build native mobile applications (iOS, Android, and Windows) in JavaScript that allows you to use ReactJS to build your components, and implements ReactJS under the hood.

Web Apps in WebView

To deliver a web application or some web pages as a part of an android client application, you can do it using WebView.
The WebView class is an extension of Android's View class that allows you to display web pages as a part of your activity layout. It does not include web browser, navigation controls or an address bar,.. just web page content.
WebView can be used to display static document that's hosted online.
WebView can also be used to build dynamic data for users.

Consuming a RESTful Web Service with Spring for Android

This Getting Started guide walks you through the process of building an application that uses Spring for Android's RestTemplate to consume a Spring MVC-based RESTful web service.

Compile và chạy ứng dụng rest server

You will build an Android client that consumes a Spring-based RESTful web service. Specifically, the client will consume the service created in Building a RESTful Web Servce.

Chạy spring boot rest: java -jar gs-rest-service-0.1.0.jar

The Android client will be accessed through an Android emulator, and will consume the service accepting requests at:

http://192.168.1.3:8080/greeting

The service will respond with a JSON representation of a greeting:

{"id":1,"content":"Hello, World!"}

The Android client will render the ID and content into a view.
