This only works on M1 Apple Silicon Macs. It offers Android devs an easy and free way to test and debug apps.This is the first preview. Visual Studio Google Emulator Manager Free Way To.In a nutshell, Reactive App is a framework for building native apps using JavaScript and React. Add the ANDROID_HOME environment variableDo you know React Native? If you don’t, you should really do something about that, especially if you’re a web developer interested in creating native mobile app. Dmg, drag/drop to /Applications, then right click in /Applications and select Open skip the developer identity verification check.Unfortunately, React Native has nothing similar, at least for the moment, forcing all Windows users to concentrate on Android… or to install a MacOS virtual machine using VMware or VirtualBox, which is basically what I’m still doing when I have to write software using XCode or React Native.Anyway, here’s what we need to do to install React Native and its Android dependencies on Windows: Install ChocolateyChocolatey is a cool package manager for Windows that will greatly help you to get the proper things without messing up your system configuration, which is rather easy using other standard, linux-oriented package managers such as npm, yarn and the likes. This is more a Apple cruel restriction than a React Native limitation, though: the sad part about mobile development nowadays is that Apple does not allow any kind of iOS emulator outside their ecosystem, thus forcing any developer who wants to create multi-platform mobile apps to develop using a Mac… Which is kind of sad, if you tell me, since nobody should be forced to use a Mac.The only mobile framework who does actually allow to do something against that is Xamarin, which lets you use a really cool iOS remote simulator for Windows. Unfortunately, we cannot build and run iOSapps, as they do require a MacOS (or, to better say, a OSX machine). Install React Native (and its dependencies)The first thing we need to do is to install React Native framework on our system, together with all its required dependencies to build and run Androidapps.
Visual Studio Google Emulator Manager Download And InstallTo do that, go to this URL and choose the Android Studio option. Install Android StudioThe next thing you’ll have to do is to download and install Android Studio. Install python2 jdk8If you already have the required version of Node.js, JDK or Phyton on your system, remove them to the above cmd to prevent Chocolatey from re-installing them. If you prefer Powershell over CMD, there’s a (even longer) one-liner for that as well.> choco install -y nodejs.Preparing the Android SDKAndroid Studio installs the latest Android SDK by default: building a React Native app with native code, however, requires the Android 9 (Pie) SDK in particular. Once setup has finalized and you’re presented with the Welcome screen, proceed to the next step. Performance (Intel ® HAXM) (if you have a INTEL CPU: if you got an AMD one, click here)Once done, click Next to begin installing these components. Make sure the boxes next to all of the following are checked: Intel x86 Atom_64 System Image or Google APIs Intel x86 Atom System ImageNext, select the SDK Tools tab and check the box next to Show Package Details here as well: locate and expand the Android SDK Build-Tools entry and make sure that 28.0.3 is selected. Locate and expand the Android 9 (Pie) entry, then make sure the following items are checked: If you prefer to do that using the menus, go to the Preferences dialog, then Appearance & Behavior > System Settings > Android SDK.Once you’re there, select the SDK Platforms tab from within the SDK Manager, then check the box next to Show Package Details in the bottom right corner. Clone a Boilerplate from GitHub and modifying it.Each option comes with pros and cons: the React Native CLI is good enough for a sample “Hello World!” application, but it’s missing some key features you’ll most likely need to add by yourself ( Redux, React Navigator, axios and so on) the Boilerplate will install a set of pre-made classes and UI elements (a menu, a navigation system, and so on) that will probably ease your development curve. Create it from scratch using the React Native CLI. Create a React Native ProjectOnce React Native and its required dependencies/components are installed, you have two options for create your first app: Add the ANDROID_HOME environment variableOpen the Windows Control Panel, select System, then Change settings > Advanced: from there, click on Environment Variables, and create a new ANDROID_HOME user variable that points to the path to your Android SDK, which should be the following (be sure to check it):If you get a message from your OS saying that “npm” cannot be found, be sure that your NodeJS installation folder is present in the PATH environment variable: if it isn’t, add it and try again. Install adobe flash mac os xRemove the previous git history by deleting the root. Copy it to another folder, such as /MyApp/ Option #1: Use React Native CLIOpen an elevated command prompt, g et in the folder you want to create your app root folder in: once you’re there, t ype the following command to create your first React Native app:… That’s it! Option #2: Cloning a Boilerplate Anyway, in the next two paragraphs we’ll deal with both scenarios. Create your configuration file App/Config/index.js (if not already present) If the project has a default name, you can also rename it to your own project name using yarn run rename — MyApp For example, if it comes with a packages.json file, it will most likely require you to run npm update or yarn install to install/update the required dependencies. Go to the Visual Studio Code official page and download it, then have it installed.Right after that, open the Extension pane (bottom last icon on the left) and install the React Native Tools, a great extension to debug and syntax highlighting React on VS Code.You’re almost done: from Visual Studio Code, do File > Open Folder, select the /MyApp/ folder – the directory you created or cloned your first app in – and open it.You should be welcomed by the following page:Now it’s time to either connect your Android phone to your computer (providing that the USB Debug feature is enabled on it – click here to read how), or to launch an Android emulator using the Android SDK using the Android Studio’s AVD Manager ( click here to read how).Right after that, from Visual Studio Code, go to the Debug screen and select the React Native debug configuration: a brand-new launch. Install Visual Studio CodeNow that our React Native app is ready, we just have to install a decent coding editor to be able to edit and/or debug it: that’s where Visual Studio Code kicks in. ANDROID_SDK_ROOT variable.Other common errors that could prevent the Android app from launching are licensing issues ( License for Android Package XXX not accepted) and the absence of a suitable emulator ( No connected devices!): the former can be fixed by opening the Android SDK Manager and installing/updating the missing packages as for the latter, just be sure to either plugin a debug-enabled Android device or launch an Android emulator from the AVD Manager. For example, as we can see in the screenshot below, the Android app will install the Gradle build tool during the first run:If you get the SDK location could not be found exception, it means that you either don’t have installed the Android SDK or you didn’t set the ANDROID_HOME variable (see below). Remember to start a Simulator or to connect an Android/iOS device before doing that!If you did everything correctly, your app should start running, installing some pre-requisites if necessary.
