How to Prevent Hot Reload in Android Studio When Switching Windows

If you are a Flutter developer using Android Studio, you may have encountered an annoying situation: every time you switch back to your emulator or to a different application, Android Studio automatically performs a hot reload. While hot reload is a powerful feature for many developers, it can often lead to unexpected UI changes, especially when making minor edits to your code, like commenting out a line. This guide will guide you through the steps to disable this automatic hot reload feature, allowing you to take control of when to see your changes reflected in your app.

The Frustration of Automatic Hot Reload

When developing an app, it is common to make frequent and small adjustments to the code. However, Android Studio's default behavior of automatically hot reloading can disrupt your workflow for several reasons:

Unwanted State Change: Minor edits can lead to unexpected changes in the app's state or user interface.

Loss of Context: Automatically reloading your app can make it difficult to understand the impact of your last change, especially if you are switching between multiple files or windows.

Decreased Productivity: If every small change results in an immediate reload, you may find it frustrating to test and debug your code efficiently.

Fortunately, you can prevent Android Studio from performing this hot reload every time you switch windows. Let's dive into the solution.

How to Disable Hot Reload When Switching Windows

Step-by-Step Instructions

Disabling the automatic hot reload feature in Android Studio is simple. Follow these steps:

Open Android Studio: Start Android Studio and make sure your project is open.

Access Settings: Go to the menu bar and click on File, then select Settings. If you are on a Mac, you will find the preferences under Android Studio Preferences.

Navigate to Appearance & Behavior: In the Settings dialog, look for the section titled Appearance & Behavior.

Go to System Settings: Click on System Settings, which is usually located on the left-hand side of the window.

Locate Autosave Options: Find the option labeled Save files when switching to a different application within the Autosave section.

Disable the Feature: Uncheck this option to disable the automatic saving of files and subsequent hot reloading when you switch applications.

Finalizing the Changes

After you have deselected the option, click Apply and then OK to finalize your changes. Now, you will have full control over when your app performs a hot reload, allowing users to trigger it manually using Ctrl+S or by clicking the reload button as needed.

Conclusion

By taking just a few minutes to adjust your settings in Android Studio, you can eliminate the frustration of automatic hot reloading whenever you switch windows. This allows you to maintain a more stable and controlled development process. With the ability to save and reload changes at your own pace, you can enhance your productivity and focus on building the best Flutter applications.

Now that you have the tools to manage your hot reload preferences effectively, enjoy smoother and more efficient development in Android Studio!
