How to Prevent Your Unity Game from Closing Entirely on Android with Application.quit

When developing games for Android using Unity, developers often encounter issues related to application lifecycle management. One such problem is how to properly handle the application closure without entirely shutting down the app. The specific scenario at hand involves using Application.quit() in Unity, which can sometimes lead to unexpected behavior, such as closing the entire application instead of transitioning to an exit activity. If you've faced this issue, don't worry; you're not alone, and there is a solution!

Understanding the Problem

In your original setup, after calling Application.quit(), you attempt to transition to an exit activity in your Android application by employing the following code:

However, instead of being directed to the Exit activity, the entire application closes. This can be frustrating, especially when you want users to have the option to exit gracefully through a specific activity.

Key Configuration

You have also defined specific configurations in your AndroidManifest.xml:

These configurations are intended to manage how the Unity player activity behaves, but they alone may not resolve the closure problem upon calling Application.quit().

The Solution

Good news! This issue can be resolved by adjusting the way you handle quitting the application. Instead of utilizing Application.quit(), you should switch to Application.Unload(). Below is a breakdown of the steps:

Step 1: Change the Quit Method

Instead of calling:

replace it with:

Step 2: Maintain Different Processes

Ensure that your activities are running on separate processes, which you have already handled correctly through your AndroidManifest.xml file. The settings for singleTask and UnityPlayerActivity are crucial for maintaining separate contexts. By doing this, when you unload the Unity context, the app does not completely shut down, allowing you to transition to the exit activity without interruption.

Step 3: Test Your Changes

After making these changes, test your application thoroughly to ensure that the exit activity opens as expected and that no lingering processes lead to unexpected application behavior.

Conclusion

By following the above steps and changing your game from using Application.quit() to Application.Unload(), you can effectively handle application closures within your Unity project for Android. This adjustment not only streamlines the user experience but also ensures smoother transitions within your app's activity lifecycle. Always remember that managing application state is crucial for creating engaging and user-friendly mobile games!
