Boost Android Emulator Performance to Save Time

Testing is one of the most important aspects during your app’s build because it allows you to see how users interact with your app. For Android developers, fragmentation is a major concern they must overcome due to OS variations. The Android Emulator is a great tool to test Android applications or Android-based Hybrid apps in a development environment.

While using Android virtual emulator in a development environment for testing, developers can configure the emulator to pretty much every possible device type available in the market. Some of the more popular devices that should be tested include Google Nexus, Samsung Galaxy, and the Amazon Kindle Fire to ensure the app matches to each device’s screen resolution. Developers can even choose the device processor type (Intel Atom or ARM) for their virtual emulator to optimize processing speed. This tool becomes even more important for developers who don’t have access to 400 different Android devices for testing.

Drawbacks

Even though Android emulator provides tremendous options for developers to make adjustments to configuring, most developers tend to avoid testing Android applications on emulator because of its sluggish loading and response time. All too often, the emulator won’t load at all to run an app.

If a developer is building an application on a low configuration machine (4 GB RAM or lower and Intel i3 or lower), then development and testing may become nightmarish. Developers may witness no sign of the emulator loading and even if it gets loaded, it seemingly takes forever to launch and load the app.

Emulator can create some serious headaches when testing Android apps.

Solution

Our Android Mobile App Developers have struggled with emulator in the past, but they’ve found an option to maximize the response time of Android virtual emulator. Below are steps to increase the RAM size of emulator beyond the configuration limit of virtual emulator.

Note*: The steps below are configured on Windows 7 machine

  1. Locate below folder location on your machine:
    • C:\Users\<username>\.android\avd\<YOUR EMULATOR>\
  2. Open config.ini (Configuration file)
  3. Update below attribute to 1024MB
    • hw.ramSize=1024MB
