Hi developer There are a lot of articles on the Internet about React Native Development, but it is not clear with what message and for whom they were written, because they all carry the meaning like “Well, this is the same React as on the web, only on mobile phones.” But people who are engaged in native development for mobile devices in flight, after all, it is impossible to understand React Native and how it works with Android without deep study. The Setting up Android Emulator which is a software product that faithfully replicates the image and functionality of Android in other operating environments. The utility creates software conditions for launching applications and transposes the Android language into a language understandable to other operating systems, using their hardware. In the article ‘How to Setup Android Emulator for React Native’ I will tell you about React based not only on web development, but on Android. All interested are welcome!
The Android emulator for a computer is necessary for software developers testing new applications for mobile devices, as well as for game lovers who lack the power and large screens of gadgets. The emulator allows professionals to test a new program or version of Android OS without the risk of harming a mobile device. Let’s see why you might need an Android emulator when working with open sources. Many people use their phones or web applications for this purpose, however, there are several reasons that speak in favor of the emulator:
- Confidentiality: Working with open sources from a smartphone, you can accidentally (or not accidentally) transfer your personal data. A virtual Android device helps you stay anonymous, so you don’t have to use your personal smartphone, accounts, or phone number to investigate.
- Fictitious GPS coordinates. Of course, the GPS location can be faked on both a smartphone and a tablet, but it is much easier to do this on an emulator. As described later in this guide, you can enter any coordinates you want to access information in various applications.
- Expenses. The most obvious reason for an Android emulator is that you don’t have to buy an additional smartphone for investigations because your primary device is an iPhone or because you need a second Android smartphone to avoid revealing your phone number and real accounts.
Genymotion is one of the most well-known Android emulator programs for Windows, mainly used by application developers. A significant advantage of the program is the low resource consumption due to the virtualization solution, which in this case is significantly simplified. And this is combined with a rich set of tools, including emulation of GPS coordinates, a shell that allows you to control sensors, and an unprecedentedly fast start-up. The emulator supports over 40 virtual devices, working with the Android SDK, Studio and Eclipse, simulating calls, SMS, battery power, Wi-Fi connections, and even front and rear cameras. Easily integrates with most well-known development environments. The product is paid, but it supports both Linux and Mac. However, there is also a free version of this program for personal use (mainly for games). It can be run through VirtualBox (developed by Oracle).
How to install Genymotion?
First, let’s create a Genymotion account for personal use by going to https://www.genymotion.com/fun-zone/. Be sure to select Gaming in the Usage Type. To confirm your registration, you will need to enter a real email address. After completing the registration and verification process, click on the Download Genymotion for personal use link found below the buttons for downloading a 30-day free trial and purchasing a paid version of Genymotion. A couple more clicks after that – and you will be taken to the page where you can download the installation file. If you have not yet installed Oracle’s VirtualBox, then select the first file (larger with VirtualBox) because this program is required to run Genymotion. While installing the VirtualBox software, your computer may panic a little (this depends on your Windows security settings). To use Genymotion, give permission to install the program. With VirtualBox and Genymotion installed, select Personal Use in the Usage notice dialog box. You have installed Genymotion, congratulations! A little more, and the virtual Android device will be at your complete disposal.
Now, let’s move to the main issue of this article – how to set it up for React Native? On Windows 10 and Android Studio, you can go to Android Studio under “File” -> “Settings” in Settings, then under “Appearance & Behavior” -> “System Settings” -> “Android SDK”. Active on the “SDK Tools” tab: “Android SDK Build-Tools ..”, “Android Emulator”, “Android SDK Platform-Tools”, “Android SDK Tools”. If everything is installed, then you can start the emulator in Android Studio with “Tools” -> “Android” -> “AVD Manager”. If the emulator is running, you can try “react-native run-android”. Instead, you can quickly launch the android emulator from the “android avd” command line. After starting the emulator, you can check with adb devices if the emulator is visible. Then you can simply use “react-native run-android” to run the application on the emulator. Make sure you have installed platform tools to be able to use adb. Or you can use “brew install android-platform-tools”. That’s all!
In the article “How To Setting up Android Emulator for React Native” I highlighted the main problems in working with React Native in conjunction with Android, described why we need Android emulators and showed step-by-step instructions for installing one of the most popular, and of course now you know how to run this emulator for React Native. Hope it was interesting and useful for you. Thanks for reading!
