6 Answers You Must Know About Android Emulators

According to recent stats, 72% of all mobile devices presently run on Android or altered versions of it; from your LGs and Motorolas to Samsungs, Pixels, and so many others. The diversity is ever-growing, great, and problematic for software developers or designers in a hurry to ship. In Continuous Delivery, software developers do not need the extra time and often resources for testing each function on a varied selection of actual Android devices. Besides, very often you might have access to an Android device or phone. But what if you do not? That’s where an Android emulator can assist.

It can simulate an Android interface and OS so that you can test your app.  As a workaround, developers often make use of Android emulators. Here’s all you need to know about the Android OS statistics, emulator as a tool, how it works, where it is mainly used, popular emulator listings, and to what extent you can depend on it while you are testing your native web or Android apps.

Introduction to Emulators

How better is an emulator? The cool-o-meter freezes at the time you don’t require a time machine to play the 1990s classics like Day of the Tentacle or Oddworld: Abe’s Oddysee on your modern PC version. No more necessity to burn a hole in your pocket to purchase the most modern Xbox or PlayStation version. You do not even need to visit your friend’s place and patiently wait for your turn to play your preferred games.

All you require is a device, an emulator, or a platform that can allow you to imitate the features and functionalities of varied OS, browsers, hardware, or software. Even if your Operating System doesn’t support a specific website, game, or app, thanks to the emulator, you don’t need to stay under rocks. You can play your most preferred game and use that mobile application you are fond of on your test software or system, even when the app and the device are normally incompatible. This way, nobody can stop you from using your picky Android app on Mac or Linux!

1. How Are Android Simulators Used To Test?

Before implementing modifications to a branch, software developers run tests on code in pipelines. After a faster unit test with the IDE, functional and instrumental testing starts. Your Android emulator lets you run instrumented tests, for instance, examining that a code handles core resources and application-precise files and tests the functionality of the external dependencies.

Emulators also aid in application performance tests to confirm that interactions are smooth and applications use device resources within the necessary restraints. For perfect results, make sure you assess the CPU and graphic capacities on your gadget. Your Android emulator just lets your gadgets run at near-native speeds. As such, you mustn’t exactly anticipate native results from them. Worse so far, on virtual gadgets, you cannot test the performance of your Android applications against different benchmarks.

There is no reliable workaround that lets you test native applications at the same scales as Android emulators. You require the majority of real devices for complicated cross-browser tests on functionalities and user interface, so you can test across Safari, Firefox, Chrome, and other browsers. 

Engineers use testing automated frameworks such as Appium and Espresso to generate test scripts and implement them on diverse Android devices to manage benchmarked compatibility standards. 

2. Android Emulator: Strengths & Weaknesses

Android emulators mimic real-time Android gadgets. But they also come with a few limitations. 


Some capacities of your Android emulator comprise faster compatibility and data transfer with physical sensors such as accelerometers.

1. Speedy Data Transfer

Android emulators assist you in transferring data sooner and more capable than physical gadgets you connect through USB. An emulator offers drag-to-drop capacities that allow you to keep .apk files on the virtual gadget from your computer or workstation, which aids software developers to test applications rapidly and more efficiently.

2. Compatibility with Physical Sensors 

Android emulators are beneficial if you use physical sensors like accelerometers. When you test a given application component that depends mainly on sensors, it becomes simpler to align your settings through extended controls from your android emulator.


Some restrictions that Android emulators come with comprise ARM processor needs, hardware acceleration complexities, disk space usage, and unpredictability in understanding app relations.

1. ARM Processor Necessities

Most modern laptops or PCs use Intel x86 and the most common Android chipset accessible is ARM v7a. Keep in your mind that for speedy emulation, the host, as well as guest CPU architectures, should match. Hence, without a gadget comprising any ARM processor, emulation becomes poor, particularly for most Android devices accessible on the marketplace.

2. Disk Space

Your Android Virtual Device manager makes varied directories to contain virtual device cache, data, and data from SD cards individually. One virtual gadget takes over 3GB of the complete disk space and may crash if you lack adequate space during launch.

3. Hardware Acceleration Complications

Hardware acceleration enhances performance, even though setting up the procedure is complicated even for advanced software developers. Sometimes, accelerates the hardware outcomes in entire system failure or downtime.

3. What are the basic hardware necessities for using Android Emulators?

Basic hardwareconfigurations requirements might vary for varied Android emulators but the following should be adequate for you to effectively run the famous ones on a Windows PC:

Operating System: MS Windows 7 & above.

Processor: AMD or Intel Processor.

RAM: Your Computer should have at least RAM around 4GB.

(Note: Having 4GB or extra disk space is not an alternative for RAM)


  • Five GB Free Disk Space.
  • You have to be an Administrator on your System.
  • Upgraded graphics drivers from MS or the chipset vendor.

4. How to keep your system from getting slow while using an Android Emulator?

  • Just examine the following things to optimize your device to experience the better ‘Android on System’ experience:
  • Update GPU drivers (AMD/ NVIDIA)
  • Ensure that Virtualization is ON
  • Configure your anti-virus so that it does not interfere with Virtualization
  • Close different programs consuming a higher amount of RAM

5. What are the Best Android Emulators?

There are loads of best options out there when it comes to picking out an android emulator for your projects like MEmu, GameLoop, and Andy. You can discover a list of the best android emulators available on the market here, along with features on which ones will function better for your specific needs. Choose the most reliable and flexible one among them. One of the best Android emulators is LambdaTest which can provide great access to Ubuntu.


LambdaTest is the most modern, advanced automation testing platform that lets you test your application on an online device farm of 3000+ real browsers, devices and operating system combinations. Run mobile app tests and search bugs at jet speed. Not merely your public application, you have the liberty to test the locally hosted applications as well. This means that even whenever your application is in beta mode, you can obtain the tests done and find bugs sooner than ever.

6. Is an emulator a rooted device?

By default, an android emulator falls under the rooted class or category. You would not require making extra efforts to fetch a root ADB shell as it would be running in the shape of a root.
