    Task Killers... The Answer from Google & Developers

    In response to the vast amount of questions regarding Task Killers, I find this to be a valuable article/video in making a determination in whether or not to use a task killer on 'auto-kill' or manually killing apps just because they're open. A task killer is meant to shut down unresponsive apps, not EVERYTHING open.

    Good explanation of how the Android OS is designed to handle applications.

    Make your decision from there
    PLEASE READ THIS!!!

    *quick cut & paste from the link*
    from the developer who designed System Panel.


    Please read this section FIRST. There are a great many misconceptions about how Android works with regard to
    starting and stopping applications.

    How to Use a Task Manager
    Android was designed from the ground up as an operating system (OS) for mobile devices. Its built-in application and memory-management systems were engineered with battery life as one of the most critical concerns.
    The Android OS does not work like a desktop operating system. On a desktop OS, like Windows, Mac OS X, or Ubuntu Linux, the user is responsible for closing programs in order to keep a reasonable amount of memory available. On Android, this is not the case. The OS itself automatically removes programs from memory as memory is needed. The OS may also preload applications into memory which it thinks might soon be needed.
    Having lots of available empty memory is not a good thing. It takes the same amount of power to hold "nothing" in memory as it does to hold actual data. So, like every other operating system in use today, Android does its best to keep as much important/likely-to-be-used information in memory as possible.
    As such, using the task manager feature of SystemPanel to constantly clear memory by killing all apps is strongly NOT RECOMMENDED. This also applies to any other task killer / management program. Generally speaking, you should only "End" applications if you see one which is not working correctly. The "End All" feature can be used if your phone/device is performing poorly and you are uncertain of the cause.

    Process Types
    The SystemPanel process listing groups applications into three categories: "Active", "Inactive", and "Internal":

    • Active applications are actually running at the present time on the device. An active application may be running in the background and not have any information currently displayed on the screen.
    • Inactive applications have been preloaded into memory, but are not actually using up any system resources. Such applications will not consume any battery power whatsoever. The memory used by these applications can be immediately reclaimed should other applications require it. As such, there is no need to manually remove these applications, as you will see no tangible benefit from doing so.
    • Internal applications are those which are part of the Android operating system itself. Some of these applications may be terminated manually, but they will be immediately restarted afterward by the OS."


    Now the video from Google.
    * Originally posted by Renthor @ DxF *

    I highly recommend people, especially those new to Android, watch the Androidology series of videos put out by Google themselves. In particular, part 2 does a great job of explaining how Android (and really Linux) is different then most people's OS experience.

    Here's the link to part 2, "Application Lifecycle"




    Bear in mind these videos are aimed at developers, but the gist of it is still applicable to everyone.

    After watching the whole Androidology series, I decided to let the OS do its thing with killing/running apps and processes. I have a task killer installed only to kill unresponsive apps that the OS can't kill for whatever reason (which by the way, is a fault generally of the app's developer(s). Not the phone or OS). And the Android OS actually comes with it's own "Task Killer" for this purpose, I just prefer to have easy "one-tap" (or close to it) access to such things.

    Here's the rest if you're interested (highly recommended. Especially if you're a dev) Videos | Android Developers

    Thanks for the link to the video. I ran across some form of this information, and have not used a task killer to just stop apps running. If I was uninstalling an app, I usually killed and released the memory and data it held, before doing the uninstall.
    Still need to do a reboot. I'm thinking weekly, would help keep down the weirdness.

    Very nice resource and a good topic for Google to finally chip in on. This makes sense, and the end all button certainly could've been the root of some users' confusion.Anyways I laughed at the part "Its built-in application and memory-management systems were engineered with battery life as one of the most critical concerns."

    This bit really hit home with me. Memory is meant to be USED.

    Im a task killer freak and I ALWAYS shut down any apps I am not using, even if I have a feeling I will have to go back to them. This vid certainly changed my view. Thanks a lot
