ICS Task Manager

Hi
When I use Task Manager on my S2 to exit applications, I am given a warning "If you force stop an app, it may cause errors" and prompted to click OK or Cancel.
Before I upgraded the firmware to ICS I don't remember getting this and if possible I would like to disable the prompt.
Any suggestions would be appreciated. :afraid:
Thanks

What is the best way to close apps?
If I use the back button to close the internet browser it still shows as an active app in task manager.

I have now placed my internet homepage as a shortcut on my homescreen, which allows me to exit using the back button. Task manager has no apps showing as active .:D
 
Hold down the Home button for a few seconds and you will be given a list of all open apps. . Then hold down on each task and select to close them.

normally u may be right, but i use sms messaging only a couple of times a day, so i want it to end each time i finish. why would i want to leave it running?
 
Is it also a bad idea to clear the Ram memory ? I've noticed it gets dangerously high in Ics usually around the 650 Mark with very minimal apps running at times.

As i have a rooted phone i also use a cache clearing app from the market.

Why do you consider that "dangerously high"? Android isn't Windows, and works in a completely different manner. If the OS requires more RAM than is available it will quickly find it by itself.

Similarly, clearing caches is self-defeating; the whole point of caching data is to save time and resources. Android is specifically intended as a mobile OS for resource-restricted devices, remember. ;)

sorry, incorrect. ie i can exit the active app, get the annoying message, & still receive messages.

True...

But the point the others are making is that you do not need to close those apps using the task manager. First, I have yet to see the stock sms app causing wakelogs which is what usually drains the battery. Second, these apps actually take very little battery anyway.

Closing apps manually, and clearing RAM has its uses, but not for everytime you want to close an app. It takes more juice to restart the launchers, widgets and background running apps after clearing RAM. So you actually lose more juice. Not to mention you have to have the screen on to do all this.

The only time I close an app using task manager is when an app is not playing nice, like opening, working or closing properly. Then I can restart the app fresh if I want to. Mostly to do with games.

The other cause is the voice talk. Sometimes it doesn't close properly and clearing RAM usually makes sure it shuts down properly. And usually that is prefixed by a long wakelog due to voice talk anyway. Also, hasn't happen for long while. Probably not since updated to GB 2.3.6.

Seriously, being trigger happy with closing apps through task manager and clearing RAM does not help your battery life, IMHO.

Cheers

I don't know what its doing under the surface but when it gets that high i notice a dip in performance. Clearing it rectifies that. Just a thing I've always done.


Plus I've never known how or why these things work. Which is why I turn to you lovely people. ;-)

I would think that the dip in performance is placebo. There would in theory be a slight dip in performance, but you shouldn't notice it.

What happens is, Android clears old applications from memory when new apps require it. This is why sometimes when you open the browser, all of the pages in the browser are refreshed, because the pages were cached in memory but they were cleared when an app required the RAM.

There would be a slight overhead when you open an app that needs RAM, and Android clears the RAM as there isn't enough free, but it shouldn't be noticeable.
