Alguém realmente precisa instalar um gerenciador de tarefas? Meu telefone faz desaceleração em ocasiões raras, mas não é algo que dificulta o uso regular.
Does one really need to install a task manager? My phone does slowdown on rare occasions but it's not something that hampers regular usage.
FAQ: Why You Shouldnxe2x80x99t Be Using a Task Killer with Android (geekfor.me) - xda-developers
- 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.
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.
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.
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:
What You Should Do Instead, e.g.:
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.
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:
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.
