If you want to get your hands dirty with some behind-the-scenes stuff on your Android phone, Task Manager is the app to open. It’s not for everyone. The Task Manager app is found on the App menu. It may not be found on your Android phone.
The Task Manager window shows all the phone’s currently running apps, along with trivial information about each one: The CPU item shows how much processor power the app is consuming, and the RAM item shows how much storage the app occupies.
You can use Task Manager to kill off tasks that are hogging up too much CPU time or memory or that simply bug the stuffing from your couch. You touch items you want to kill off and then touch the End Apps button. The apps are silently snuffed out.
A nifty feature in Task Manager is the Auto-End list. When apps have been assigned to this list, they automatically exit two minutes after the display times out. To add apps to the list, select them from the main screen and touch the Add to Auto-End button at the bottom of the screen.
There’s no need to kill off an app flagged as “not running.”
Task Manager doesn’t delete apps; it merely stops them from running. To delete an app, use the Android Market.
The Android operating system does an excellent job of managing apps. If resources are needed for another app, Android automatically closes any open apps as needed. There’s no need to futz with Task Manager, unless you just enjoy messing with such a thing.
