Task Manager

The Task Manager allows viewing and stopping processes, services and tasks. Its main features include application management, process management, battery and other system information. With the auto stop feature processes can be stopped periodically.

Notes:

The SD card icon can only be shown with Android 2.3 and above.

If you don't need a task manager, you can check out the Application Manager, the Battery Display App or the CPU Display App for some of its functions.

Close processes:

In Android it is possible, that some processes with services (e.g. the Battery Display) will be restarted directly by the system, after they were closed. This behaviour exists in some other task managers, too (e.g. the one of the Galaxy S2). Some processes cannot be killed (noticed on the Galaxy S2 with Android 4.0.4). I am looking for an option, to close processes not the 'light way'. I think you need 'Root' then.

Update notes:

All services of the application will be stopped during the update. Please go to the auto stop feature activity and leave it again to restart them. If the services are not running, no auto stop will occur.
