常见问题:为什么您不应该使用Android(Geekfor.me) - XDA的任务杀手-developers

tl; dr版本:

  • Android很难编码,以在需要更多内存时自动杀死任务。
  • android很难编码,以便在完成它需要做的事情时自动杀死任务。
  • Android很难编码,以便在很长一段时间内没有返回它时自动杀死任务。
  • 大多数服务(在后台运行时)在不积极地做某事时使用很少的内存。
  • 内容提供商只是在有通知时做某事。否则它使用非常小的内存。
  • 在没有准备就绪时杀死一个过程只会导致它必须重新加载自己并在再次需要时从头开始。
  • 因为一项任务可能在后台运行,因为有原因,杀害它只会导致它尽快再次产卵,这是使用它再次寻找它的活动。它只必须重新开始。
  • 杀死某些过程可能具有不希望的副作用。没有收到短信,警报没有脱落,而力关闭只是为了命名几个。
  • 阻止您手机上运行的唯一真正方法将是卸载.apk。
  • 大多数应用程序将通过击中"后" 而退出自身,直到它关闭而不是击中"HOME" 按钮。但即使在击中家庭时,Android将最终杀死它一旦在后台就会杀了一段时间。

FAQ: Why You Shouldnxe2x80x99t Be Using a Task Killer with Android (geekfor.me) - xda-developers

tl;dr version:

  • Android is hard coded to automatically kill a task when more memory is needed.
  • Android is hard coded to automatically kill a task when itxe2x80x99s done doing what it needs to do.
  • Android is hard coded to automatically kill a task when you havenxe2x80x99t returned to it in a long time.
  • Most services (while possibly running in the background) use very little memory when not actively doing something.
  • A content provider is only doing something when there is a notification for it to give. Otherwise it uses very little memory.
  • Killing a process when it isnxe2x80x99t ready only causes it to have to reload itself and start from scratch when itxe2x80x99s needed again.
  • Because a task is likely running in the background for a reason, killing it will only cause it to re-spawn as soon as the activity that was using it looks for it again. And it will just have to start over again.
  • Killing certain processes can have undesirable side effects. Not receiving text messages, alarms not going off, and force closes just to name a few.
  • The only true way to prevent something from running at all on your phone would be to uninstall the .apk.
  • Most applications will exit themselves if you get out of it by hitting xe2x80x9cbackxe2x80x9d until it closes rather than hitting the xe2x80x9chomexe2x80x9d button. But even with hitting home, Android will eventually kill it once itxe2x80x99s been in the background for a while.

As Android was designed you don't need to kill apps.




No, and even more so with the latest 2.2 versions of Android. I used to use them, but I've stopped and everything has been better since I stopped using a task manager/killer. There is an app called Watchdog if you'd like to be notified about a process using a ton of CPU for a long period of time, which then will give you the option to kill that run-away process.



我有失控的进程(也许看门狗可以提供帮助),如谷歌地图,然后是两次的谷歌地图,一次杀死我的CPU / RAM并一次实际工作。我不得不使用任务杀手来杀死两个实例,然后运行正常的实例。



Yes. You should have a task-killer app, but not for the reasons you think.

I've had runaway processes (maybe watchdog can help) like google maps which then ran twice, once to kill my cpu/ram and once to actually work. I had to use the task killer to kill both instances and then run the normal one.

RARELY will you actually need to manually kill anything. But like all programs, sometimes stuff happens. I've had apps crash the entire phone and they were not running in root or anything.


有时当一个应用程序崩溃或达到一个状态时,它不是响应的,能够手动关闭它。 。 。但是对于Slowness问题,如果OS本身现在掌握多任务处理,则不需要任务管理器。


Sometimes when an app crashes or gets to a state that it's not response it's nice to be able to shut it down manually . . . but as for slowness issues a task manager isn't necessary as the OS itself handles multitasking better now.


这个全面,信息丰富的amp;易于阅读的文章题为" Android任务杀手解释说:他们做了什么以及为什么你应该使用它们"将为您提供Android如何通过它自行处理过程管理的快速概述默认。 (基本上不需要任务管理器/杀手应用程序 - 在Android OS的早期版本中更有用)


  • Android如何管理进程
  • 为什么任务杀手(通常)坏消息
  • 你应该做的是什么,例如:

    • 监视失控流程
    • 卸载不良应用
    • 可能root手机(虽然没有必要)

This comprehensive, informative & easily readible article entitled "Android Task Killers Explained: What They Do and Why You Shouldnxe2x80x99t Use Them" will provide you with a quick overview of how Android handles process management on its own fairly well by default. (Essentially that a Task Manager/ Killer App is not required- it was more useful in early version of the Android OS)

The Article will explain:

  • How Android Manages Processes
  • Why Task Killers Are (Usually) Bad News
  • What You Should Do Instead, e.g.:

    • Watch for Runaway Processes
    • Uninstall Bad Apps
    • Possibly Root Your Phone (although not necessary)


现在我有姜饼,我只需在设置菜单中的应用程序下使用"运行" 列表。


When I was running Froyo, I installed task manager not to kill tasks, but to find an easy to review list of what is running and learn more about how apps work. This seemed the easiest way to learn what was running quickly.

Now that I have Gingerbread, I just use the "running" list under applications in the settings menu.




  • 严重编程的应用程序(大多数)
  • android清理内存和卸载东西才能腾出空间(这应该只是临时的,但在旧的设备上或与自定义ROM非常烦人)




Ideally, you don't need a task manager for the reasons mentioned by Cristi.

Random slowdowns on Android are likely from one of two sources:

  • Badly programmed apps (mostly)
  • Android cleaning up the memory and unloading stuff to make room (this should be only temporary, but can be very annoying on older devices or with custom ROMs)

If you experience slowdowns, and can't or don't want to uninstall the apps that cause them (or you don't know which ones it is), then a task killer can really make a difference. The same applies for older devices that don't have enough RAM.

So: it shouldn't be neccessary, but you might try it as a workaround if you have misbehaved apps on your device.
