Out on the search for an online Android emulator to test out some apps on the go? Here’s everything you need to know about web-based Android emulators and a step-by-step guide on how to use one.

Android OS is easily one of the most widely used mobile software platform there is, and there’s a good reason for. Apart from being highly versatile, Google has kept Android OS open-source, meaning that developers, and even end-users can choose to use devices running the mobile OS and even modify it easily. Since Android OS is based on the Java programming language, the Android SDK (System Development Kit) has been traditionally used by developers to create, modify, and test out apps for various Android devices.

Over the years, the Android OS platform has received a significant boost with the evolution of the Google Play Store. The addition of an add marketplace with millions of offerings has changed the way people use their mobile devices. In recent times, there has been a significant growth in users who have been using their computers to run virtual machines based on Android OS. The software that allows this is called an Android emulator, and the popularity of Google’s mobile platform has created an entire community around it.

What is an Online Android Emulator

Android emulators have existed for several years, helping developers test out apps on their local machines, hammer out the kinks and make it ready for deployment on the Google Play Store. Similarly, mainstream users have also enjoyed the use of Android emulators to run mobile apps on the big screen, manage messaging and social media accounts directly from the computer, and even play high-definition mobile games such as Player’s Unknown Battleground with better gameplay controls. However, since an Android emulator needs to be installed as software on the Windows, Mac, or Linux device, it can be restrictive at times.

For when you are on the go and need the ability to quickly test out an app, the only solution is an online Android emulator. With a web-based Android emulator, you can simply skip past the installation phase that is needed with a traditional Android emulator and boot it all up on the cloud.
