Android 14 no longer allows “Killing apps in background”!
In the Android application store, there are many apps that provide “one-click acceleration” function, which speed up the mobile phone by cleaning the background applications in the Android system.
Is such an operation useful, and is it reasonable for such an App to exist? With the release of Android 14 DP2, Android users have an official explanation.
Generally speaking, this type of “one-key acceleration” app has a special permission (KILL_BACKGROUND_PROCESSES), which clears background applications by executing system commands (ActivityManager.killBackgroundProcesses), and simply and roughly kills resident processes in memory to reclaim memory.
Starting from Android 14, the API for App to obtain the above-mentioned special permission (KILL_BACKGROUND_PROCESSES) will be restricted. “One-click acceleration” apps, including all apps that can get the permission to kill the background, will only be able to clear their own background processes.
It is no longer possible to clear the background processes of other apps, which means that the “one-key acceleration” app will become history, and the situation of multiple apps fighting each other in the background will no longer happen.
Android gave an explanation for this. According to the description document of Android 14DP2, Android believes that applications “should not use killBackgroundProcesses() API or other methods to try to affect the process of other applications.
Android is designed to keep cached apps in the background and automatically kill them when the system needs memory. “One-key acceleration” app unnecessarily clears other app processes, which may reduce system performance and increase battery consumption.
Because the system needs to completely restart these applications later, this requires more resources than restoring existing cached applications. Starting from Android 14, only system apps with the new permission KILL_ALL_BACKGROUND_PROCESSES can kill background processes of other apps.
Also, an interesting detail is that the description document also mentions: “Third-party apps cannot improve Android device memory, power, or thermal behavior.”
