RootTools create zombie process about roottools HOT 4 OPEN

What does your code do, other than checking for root? The snippet you attached is not very informative.

from roottools.

@Fusion

The purpose of that snippet is to check for Root without freezing the UI (from a secondary thread) on Activity.OnResume.
If the device got Root, I finish() the current activity.

The problem is that every check RootTools.isXxxx() create a few Zombie (process that are not terminate until a device reboot)
Thoses Zombie use all the RAM memory of the device until the point when the device completly stop being responsive.

Every time "su" is executed, it spawns a zombie process that survives the application and grows in memory allocation. Ouch!

the solution is simple yet powerful: start your own custom su daemon :)
this way you only need to show the root confirmation dialog once every reboot and you can keep a list of pid's in memory which you can retrieve even when your app process got killed by a task manager:
