iPhone simulators however are free from hardware constraints such as running out of memory. This means that on Android Emulators, you can be reasonably confident that the physical device will act similarly to the emulator. Simulators, on the other hand, only mimic the software environment they otherwise have access to all of the host system's hardware resources such as disk space, memory and processor speed. The difference between emulators and simulators is that emulators mimic the software and hardware environments found on actual devices. You may have noticed we've been saying "iPhone Simulator" and "Android Emulator". You can then go back to Settings → Developer options to enable "USB debugging".įor any platform-specific issues and nuances, consult the documentation. * To enable USB debugging on your device, you will first need to enable the "Developer options" menu by going to Settings → About phone and then tapping the Build number row at the bottom seven times. close the Android emulator (if you had it open).That's it! You're now up and running on your android device. Now that we've got all the environment prep out of the way, let's get started and create our application. Once you're done, let's pick up from "Creating a New Application" together. If you are on a Mac, you may want to choose iOS for this workshop, as the setup tends to be easier than Android on a Mac. If you want to test on your own iOS device but you don't have a Mac, you may want to look into using Expo instead.įor getting started, follow the React Native CLI quickstart in the environment setup guide until the section titled "Creating a New Application". This is why a lot of React Native developers end up using MacBook Pros, since this way you can work on both native apps are the same time. Note! If you are using a Windows or Linux machine, you won't be able to build the iOS app, but you can build the Android one. If not, you should expect to spend an hour or so on installing and configuring them. If you already have these installed, you should be up and running within minutes. This requires Android Studio or XCode in order to get started. If you are already familiar with mobile development (or if you can't or don't want to use Expo), you may want to use the React Native CLI.
