Task Manager for any CyanogenMod/CyanMobile roms

Alternatively, you can use Root Explorer or similar other app to install TaskManager on your device.

• With the help of root explorer copy the TaskManager.apk file from above to system/app/ directory. [You may need to remount system as read/write using the R/W button at the top of the app before you can make changes to system files.]
•  Now navigate to /system/app/ folder and long press on TaskManager.apk file to get a list of menu options. Select Permissions from the menu (you should see something like below --not exactly the same though.)
• Then, Set appropriate permissions : Read-write for Owner and Read only for Group and Others. Or more specifically, set permission to rw-r-r. You can also use root explorer permission option to set the permission as shown below.
