Android Task Killers: How Do Killing Background Tasks And Services Actually Help,
In a desktop OS, like Windows, advertisements by connecting a program, the OS will search the "prefetch" cache, and load from when available. If the program is just not in the prefetch, it will be loaded from your hard drive, using a copy loaded into prefetch. When you quit this software, this program unloads from RAM, but stays within the prefetch, thus it can be retrieved quickly if you need it again.
Prefetch also predicts what you would want to use next, and prefetches several of that, to increase response speed. In later versions of Windows, like Vista and Win7, the leading memory is employed as much as possible to aid with the prefetch. A mobile OS, including Android, want to do something very similar. The difference is at Android OS, program that 'ended' will not be actually unloaded from operating memory, until other programs actually request more memory. By keeping enter in memory, it might be immediately accessed again.
If a ask for more memory is created, THEN existing programs are killed, in accordance with the use frequency, to generate more room for your new program. Most Android programs do NOT have a "quit" function in any respect. NOT accessed, they can't slow down the computer. Furthermore, since Android system powers all memory simultaneously, not selectively, killing programs not being utilised actively will not likely save any power in any way. Thus, killing regular running process does NOT build your system more responsive, nor will it save power.
Any claims which they do so is often a myth. Where did the Myth Came From, The myth which you will want Task Killers came on the days when Android phones consist of VERY little memory. The original TMobile G1 had only 192 MB of RAM. The Motorola Droid was included with 256 MB of RAM. Modern Android phones like Samsung Galaxy S series or HTC Evo / Incredible have 512 MB of RAM. The Android OS will wipe out programs that usually are not immediately needed if it needs to load another app (for instance receiving email, making or receiving calls, etc).
However, it's not possible to control the thing that was killed. You can't specify "kill this, and not that". Task Killers assist you to anticipate the automatic killing process by killing off programs except those within the "ignore list". If there's enough space, no automatic killing must take place. However, if that is just not sufficient, apps and services will still get killed.
If you kill an active component that the OS still needs seeing as there are other programs calling it, Android OS only will restart it immediately. If it is needed later, the task is going to be killed now, but restarted if it is called. However, not every services along with programs will gracefully accept the "lag" that this OS would need to restart this course.
That's why sometimes you will see this "Force Close / Wait" dialog box, once the Activity (UI) calls another parts from the app, but failed to get a response back. If there is enough memory, then Task Killer will still only slow it down as takes stuff OUT of memory merely to see them loaded way back in when they are called again.
Thus, Task Killers are NOT needed on phones with 384 MB or maybe more memory. Is this software still running, A game that runs in "real-time" might have multiple portions: a task to detect user input, a broadcast receiver to get tilt sensor and button messages, a site to do background processing, etc. In contrast, an internet browser doesn't have a more activity to execute upon the finish of the surf session, until it receives another user command. Thus, in the event you exit out of a website browser, the app is going to be deactivated (i.e. not unloaded, just will no longer run).
