Xcode mac 11 android#
If you're already familiar with Android development, there are a few things you may need to configure. Setting up your development environment can be somewhat tedious if you're new to Android development. You may encounter problems using higher JDK versions. If you have already installed JDK on your system, we recommend JDK 11. This will make sure your builds are faster on M1 Macs compared to using an Intel-based JDK. The Zulu OpenJDK distribution offers JDKs for both Intel and M1 Macs. Select "React Native CLI Quickstart" above for instructions on configuring a native build environment for React Native. If you're integrating React Native into an existing project, you can use the Expo SDK and development builds, but you will need to set up a native development environment. You can check this document to find out what versions are supported. The Expo Go app usually gains support for a given React Native version with new SDK versions (released quarterly). Learn more about adding native code to projects created with create-expo-app.Ĭreate-expo-app configures your project to use the most recent React Native version that is supported by the Expo SDK. You can leverage these libraries with development builds, or by using "prebuild" to generate the native projects, or both. There are many great libraries available outside of the Expo SDK, and you may even want to build your own native library. The tradeoff is that the Expo Go app does not allow you to add custom native code - you can only use native modules built into the Expo SDK.
Xcode mac 11 install#
Expo Go makes this possible by including a feature-rich native runtime made up of every module in the Expo SDK, so all you need to do to use a module is install the package with npx expo install and reload your app.
The Expo Go app is a great tool to get started - it exists to help developers quickly get projects off the ground, to experiment with ideas (such as on Snack) and share their work with minimal friction. Once you've set these up, you can launch your app on an Android Virtual Device by running npm run android, or on the iOS Simulator by running npm run ios (macOS only).
Xcode mac 11 how to#
If you want to run your app on the iOS Simulator or an Android Virtual Device, please refer to the instructions for "React Native CLI Quickstart" to learn how to install Xcode or set up your Android development environment. Running your app on a simulator or virtual deviceĮxpo Go allows you to run your React Native app on a physical device without installing iOS and Android native SDKs. If you're curious to learn more about React Native, check out the Introduction to React Native. If you have a problem with Expo, before creating a new issue, please see if there's an existing issue about it in the Expo issues. You can also ask for help on the Expo Discord. Now what?Įxpo also has docs you can reference if you have questions specific to the tool.
That's it!Ĭongratulations! You've successfully run and modified your first React Native app. The application should reload automatically once you save your changes. Open App.js in your text editor of choice and edit some lines. Now that you have successfully run the app, let's modify it. On iOS, use the built-in QR code scanner of the default iOS Camera app. On Android, use the Expo Go app to scan the QR code from your terminal to open your project. Install the Expo Go app on your iOS or Android phone and connect to the same wireless network as your computer. This will start a development server for you.
