Google’s latest Android 15 update introduces new changes to the way apps behave on Android devices. One of the notable features is the adjustment to app behaviour when a user forces an app to close. This update ensures that not only the app itself but also its associated widgets are properly handled during this process. These adjustments aim to improve the overall user experience, security, and app management on Android devices.
Adjustments to App Behavior
When a user forces an app to close, the system will now terminate or cancel any pending intents associated with the app. Intents in Android are messages from an application to act, such as starting another activity or sending data between apps. Previously, these pending intents could remain active even after force closing an app. This potentially leads to behaviours or security vulnerabilities that users do not need. By cancelling these pending intents, Android 15 ensures a more robust shutdown process, enhancing both stability and security.
This change is particularly important for ensuring that apps are properly shut down when needed. In earlier versions of Android, users might have experienced issues where forced-stopped apps left residual processes or notifications, causing confusion and potential security risks. By fully terminating these intents, the system can more effectively manage app states and resources, ensuring that forced-stopped apps do not continue to operate in the background.
Widget Behavior
Widgets are an integral part of the Android experience, providing users with at-a-glance information and quick access to app functionalities directly from the home screen. With the Android 15 update, the behaviour of these widgets has been carefully reconsidered to align with the new app management policies.
When a user force stops an app, the system will temporarily disable and display widgets in grey until the app restarts. This means that users cannot interact with the widget on the home screen until they restart the app. The design of the update ensures that it prevents any potential issues that might arise from widgets trying to access data or perform actions while the app is not running.
According to the official Google developer log:
“If a user force stops an app on a device running Android 15, the system temporarily disables all widgets for that app. These widgets will be grayed out and users will not be able to interact with them. This is because, starting with Android 15, when an app is force stopped, the system cancels all pending intents for the app. The system re-enables these widgets the next time the user launches your app.”
This approach ensures that widgets remain in sync with the app’s state, preventing the display of any old or incorrect information.

Developer Tools and Methods
To assist developers in managing these new behaviours, Google has introduced the “ApplicationStartInfo.wasForceStopped()” method. This method allows developers to confirm whether their application is in a stopped state, providing them with the ability to handle app state changes more effectively. By using this method, developers can ensure that their apps and widgets behave correctly and provide the best possible user experience even after a force-stop event.
User Interaction
Despite these changes, users can still open the app directly by tapping the icon or indirectly through the “Share” menu in other apps. This ensures that users can still access the app’s functionality even if the widget is temporarily inactive. By providing multiple ways to restart the app, Android 15 ensures that users have control over their app usage and can quickly restore functionality when needed.
Benefits of the Update
The adjustment to app behaviour and widget handling in Android 15 provides several benefits to users:
1. Improved Security: By cancelling pending intents and disabling widgets, the system reduces the risk of malicious apps exploiting these features to perform unauthorized actions. This is particularly important for preventing potential data leaks or unauthorized operations that could compromise user privacy.
2. Better User Experience: The update ensures that apps are properly shut down when needed, reducing the likelihood of issues caused by apps trying to access data or perform actions while not running. This leads to a smoother and more predictable user experience, as users can trust that force-stopped apps are fully inactive.
3. Better App Management: The ability to restart an app directly or through the “Share” menu provides users with more control over their app usage and helps them manage their apps more effectively. This flexibility allows users to quickly regain access to app functionalities and ensures that widgets are only active when the corresponding app is running.
4. Resource Optimization: By fully terminating apps and cancelling pending intents, Android 15 helps optimize system resources. This can lead to better performance and battery life, as the system will not overlap due to residual processes or widgets.
Developer Considerations
For developers, the Android 15 update brings both challenges and opportunities. Ensuring that apps and widgets comply with the new force-stop behaviours requires careful testing and possibly modifying existing code. However, these changes also provide an opportunity to enhance app reliability and security, which can lead to better user reviews and increased user trust.
Developers should update their apps to handle the new widget behaviour appropriately. This may involve ensuring that widgets check the app’s state before attempting to perform actions or access data. By leveraging the “ApplicationStartInfo.wasForceStopped()” method, developers can design their apps to gracefully handle force-stop events and ensure a seamless user experience.
Conclusion
The Android 15 update brings changes to app and widget behaviour, particularly when a user forces an app to close. This update ensures that not only the app itself but also its associated widgets are properly handled during this process. The benefits of this update include improved security, enhanced user experience, and better app management. It also reduces the risk of unintended behaviours and provides users with more control over their device usage.
