Gestione delle Attività in Background

In 2025, an app running in the background is defined as one where none of its activities are visible to the user, and it is not running any foreground services. Background tasks can be categorized into asynchronous work, task scheduling APIs, and foreground services, with different methods suited depending on the task’s nature and duration.

• Asynchronous work (e.g., Kotlin coroutines, Java threads) is for concurrent operations while the app is in the foreground, but these stop when an app goes to the background.
• Task scheduling APIs, such as WorkManager or JobScheduler on Android, enable tasks that need to continue running even if the user leaves the app. These are suitable for periodic data fetching, sensor readings, or location data acquisition. WorkManager is the preferred tool due to its flexibility in scheduling and chaining tasks.
• Foreground services are used for critical, continuous tasks that must not be interrupted and need to be noticeable to the user. These carry more system restrictions for performance and privacy reasons.

Apps must select the appropriate API based on whether the task needs to run when the app is backgrounded, how critical and long the task is, and whether alternatives exist for specific use cases (like geofencing instead of continuous location tracking) to optimize resource efficiency and user experience ^[1].

For more typical consumer uses, like playing YouTube videos in the background on iPhones in 2025, users can enable Picture-in-Picture mode or specific playback settings to allow apps to operate in the background without requiring premium subscriptions ^[2].

If users want to manage or close background apps on devices such as TCL or LG smart TVs or Android phones, there are updated procedures and apps available in 2025 to quickly close or freeze background apps to improve device performance ^{[3] [4] [6] [8]}.

In summary, apps in 2025 use a layered approach to background activity management, balancing resource efficiency, user experience, and system restrictions with tools like WorkManager for Android and Picture-in-Picture mode or playback settings on iOS.
