ForceKill Focused

LSPosed module for OneUI 8.5 that adds a Force kill item to the per-task popup menu in Recents, directly below Keep open.

Tapping it swipe-dismisses the task card, closes the menu, force-stops that one app (the tapped task only), and removes its Recents card.

Requirements

• Samsung device on OneUI 8.5
• Root via one of:
  • Magisk + Zygisk + LSPosed
  • KernelSU + ZygiskNext + LSPosed

There are no separate Magisk/KernelSU builds. It's a plain LSPosed APK hooking com.android.systemui (and the OneUI launcher), so it works anywhere LSPosed runs.

Install

1. Download the APK from Releases and install it.
2. In LSPosed Manager, go to Modules and enable ForceKill Focused.
3. Set the scope to com.android.systemui and com.sec.android.app.launcher.
4. Reboot, or restart SystemUI.
5. Open Recents, tap a task's icon, then tap Force kill.

How it works

Everything lives in one file, MainHook.java.

• Menu injection: OneUI's task menu is a custom DataBinding view (task_menu_layout containing task_menu_item_layout rows), not a framework PopupMenu. This was verified via on-device resource and stack-trace inspection.
• Hook point: LayoutInflater.inflate() is hooked. Each task_menu_item_layout inflation schedules a post() that clones the row below the Keep open row, which is matched by its task_option_dedicated_app string. A marker tag ensures only one copy is added.
• Target resolution, in order:
  1. The tapped card's TaskView.getTaskPackageName() (exact)
  2. The view-tag chain (TaskIconView args)
  3. The top non-system recent task
• Kill sequence: hidden ActivityManager.forceStopPackage(), then killBackgroundProcesses(), then removeTask(). This runs inside the hooked process (SystemUI / launcher), which holds the required permission.

Troubleshooting

Recents internals change between OneUI builds.

• Button doesn't appear: get the Recents activity name and check that it matches the module's substring filter:

  adb shell dumpsys activity activities | grep -i recents
