It may take a few minutes for the CLI to complete, as it will create the folder structure and set up dependencies. Open a terminal, go to a folder where you want the app to reside, and launch the following CLI command to create an app called ZSDKRCTDevDemo.
Once the environment setup is complete, you can go ahead to create a new React Native app. Simply follow the instructions in the Environment Setup doc to set up the development environment.If you have the latest Android Studio and Xcode installed on a MacBook, you can add the Link-OS SDK into a React Native project and expose the native methods through the Native Module system for both Android and iOS on the same MacBook. The environment setup for React Native is well documented. The source code for this tutorial can be downloaded from ZSDKRCTDevDemo on GitHub. Print a test label when tapping on a printer on the list.Scan for nearby Bluetooth printers on Android or list the paired Bluetooth printers on iOS.In this tutorial, we will create a React Native app with a simple use case that just does two things: We will demonstrate the steps of how to expose the native methods that are based on the Link-OS SDK libraries through the Native Module system. The Native Module system in React Native framework allows us to expose instances of Java or Objective-C classes to JavaScript as JS objects, therefore we can call and execute the native methods from JavaScript. Is it possible to call Java or Objective-C native methods from React Native? Thanks to the Native Module system provided in React Native framework, the answer is yes.
In this tutorial, we will walk through the steps of how to add the Link-OS SDK into a React Native project for Android and iOS, so that the React Native app can perform label printing through the native API in the Link-OS SDK.Īs we know, React Native is written entirely in JavaScript, while the Link-OS SDK libraries are written in Java for Android and written in Objective-C for iOS. Often, we have developers asking about how to integrate the Link-OS SDK with a React Native app for label printing on Zebra printers. Since its release in 2015, React Native has become one of the popular cross-platform mobile development frameworks used to build thousands of mobile apps. Global Solution Centers - Testing Services.
