Close an Application?

Hi
This might be a stupid question, but anyways:
I bought me a HTC Desire yesterday and im very happy with it.
Now i installed the Advanced Task Killer as i heard its a good app.
Now, every time i open something, like the SNESoid Player, or even my SMS(Messages), and the close it by pressing the Home or back button, i see afterwards in the Task Killer that its still running!?
So, how do i "close" an application, or is this just normal? It's pretty weird to me.
Thanks

This is one of the most asked and answered questions. Search and you shall find.

You probably used a WM device before Android I can imagine. Android OS handles all that stuff automatically, you shouldn't worry about apps not closing because when an app isn't used it isn't using either memory or CPU. When a new application opens and needs memory, the one(s) still running will close and give space for the new one.

As "ArtieQ" said it's not recommended to use a task killer.
But if you really need to stop a program you can use your native task manager, from "settings">applications>manage applications - then when the list of applications loads, you can press menu button and choose "filter" and then "running". Now when you choose an application from the list, it will show you information for it and an option to "force stop" it, that is to close it.

Thanks alot!
Well, i used a crappy iPhone 3G before..no multitasking you know

I was looking for an answer to this question and find something here but I am still a little bit confused : many applications that I have tested dont close if I press the home or the back button and they don't have any "quit" or "exit" command or menu entry. I was facing some battery issues with all these apps in the background. It's true that uninstalling some of them and force closing others in the app manager solved the issue but it is really not confortable to go in the app manager every time after using the phone to close the apps and save battery. I am wondering if an auto-close application exist in the market...

Advanced task manager has an autokill function within It's settings. It also has a desktop widget that you can press to kill apps when you want. You will probably want to add some of your apps to the ignore list though so notifications etc still work ok

I remember that installed somthing like advanced task manager and it ended up by eating my battery charge cause it was running all the time. I'll test this and report back.
Thanks for the tip

Instead of using a task manager/killer consider using 'autostarts' which is an app (paid) which allows you to stop apps starting automatically.
For example, maps gets started when you do almost anything and once started really eats your battery.
I've been using autostarts for a while now and would definitely recommended it for battery saving.

thanks for this tip iain2510

Titanium backup not freezing apps

Anyone with this issue? It allows me to freeze them. Says they're frozen. But then they're not grayed out and they are still active.

Yep. Noticed that the first day I had the Nexus. In ICS you just go to Settings->Apps and freeze from there. It is part of the OS and one of the best things they added!

Wow. Thanks. Didn't realize that.
Edit: I don't see that option in Setting -> Apps. Am I missing something?

Sorry... I was going too fast this morning... Select the app, click on it and it should see an option to deactivate or uninstall. System apps will show deactivate and regular apps uninstall...
I am not on my phone so I don't remember the precise label for the option...

Thanks again. I'm actually trying to freeze non-system apps. But that's definitely good to know.

Close all?

Yes was hoping for an all close at once type app. Had that on iPhone thought might have something similar.

There are 3rd party app killers in the play store. Check there...
There was a stock task manager...but I guess Google removed it for JB

App killer

Cyanogenmod 10.1 has a button on the multitasking menu to do that. But it's kinda pointless except to clear the list of recently used apps. Android, if my understanding is correct, automatically fills the memory with tasks so killing apps is worse than pointless since you're just causing the system to prioritize unused background processes over the ones that you use more often.

You should listen to this guy. I know you're coming from a different OS, so you aren't aware of how Android deals with memory. The system is very good at multitasking. Apps that have been idling in the background will be pushed out and won't consume resources or ramp up your CPU. By killing those apps, you force the system to have to reload and process resources necessary to start the app. Android will keep enough of the resources to quickly fire up the app, but restrict activity so that your battery is pretty much unaffected.
An analogy if you need it: Android will bookmark and close whatever you were reading. That way, you can move the book around or leave it on the shelf and quickly pick it up and continue from the last page you were on. You are requesting that the system instead just closes the book, and buries it in a box with other books, and which is located in the attic. It takes more resources to find the book and locate the page again. Just let Android do its thing. Any popular dev will tell you the same thing.
TL;DNR - Don't use a task killer, you will get far better battery life and performance if you let the system deal with system resources.

Don't listen to this guy. He used the phrase "smart one," which I haven't heard since I was in elementary school (and I thought it was un-clever and uselessly sarcastic then). He also thinks that swiping away apps from the recents menu kills them. This is not how Android works. AOKP devs will not implement a recents menu that actually does let you swipe to kill apps because it's a useless feature that does more harm than good (zero benefit, actually). Just trust that your system knows how to handle its resources.
TL;DNR - Swiping away apps from the recents menu doesn't kill them. Stop trying to kill apps; only do so if they're unresponsive.

If u really want it, aokp has this feature

Let's say I start loading a web page and quickly jump to another app before it's loaded, then when I return to Chrome the page is ready and waiting. Doesn't this imply that apps are not just simply bookmarked and closed, but may remain active in the background? I am asking, not saying btw.

Foreground apps are told that they are no longer in view, but are allowed to keep running if they wish. The OS will stop them if the memory is needed - which with 2GB is not very often on the nexus 4!

So Hung0702 was wrong on the last page when he said:

It seems as though background apps can use resources and may have a negative impact on battery. Now I have got to the bottom of this I also want a clear all button!

Yes, they can keep using resources in the background. However, they will usually not keep the cpu awake unless they have an actual background service, so they will not stop the device from sleeping. As far as I know this is not enforced, but most apps will release the wakelock when told to pause by the OS (because the app is now hidden). This means they shouldn't have much impact on battery life.
You can see what is currently running by going to Settings -> Apps and select the Running tab. The recent apps list is not the same - most will have actually closed when you hid them.

Samsung Galaxy S6 Edge+ Battery Saving Tips

A phone even with killer looks and amazing features still needs a descent battery backup to support it all. In past we've seen that a few tricks here and there always tend to increase battery life. Usually that includes disabling a few apps or features. This thread is for specifically targeting such tips & tricks and sharing it all so that S6 Edge+ can live upto its expectations..

1. To start with, lets get to the list of bloatwares that can be safely disabled.
If any of you own the AT&T version, here's a list you can disable:-
AT&T Apps:-
AT&T FamilyMap
AT&T Hot Spots
AT&T Live
AT&T Locker
AT&T Mail
AT&T Mobile Locate
AT&T Mobile Transfer
AT&T Navigator
AT&T Ready2Go
AT&T Smart Wi-Fi
Drive Mode
Caller Name ID
Mobile TV
Plenti
Smart Limits
Yp (Yellow Pages)
Other Apps:-
S Voice
Amazon (I prefer the playstore version for frequent updates)
Amazon Kindle
Device Help
Live Weather (Yahoo)
Lookout
Theme Store
Visual Voicemail
2. Refrain from using any free application that has embedded advertisements. They tend to run threads in background to load adds and thus degrade the app performance and used data (so naturally consume more power too). Either buy add-free version or find an alternate app for same purpose and without adds.
3. Disable notifications from social media/news apps like Facebook, Twitter, Tapatalk, etc. Although, the phone wouldn't be that smart if all the notifications are disabled, however, keep them at bare minimum. Not everybody would be interested in notifications from all the apps, so spend some time analyzing through all the installed apps and their settings to turn off the notifications for the apps you do not need to get notifications for. There are several apps that keep sending notifications and running a thread in background which again checks internet to load the notification content. An example would be games like Candy Crush or Clash Of Clans.
4. Turn off "Send Usage Statistics" or "Help Improve the app performance", "Participate in improvement" etc settings from the app which sends data from your device from time to time which acts as a survey to improve the performance of the app. Although this is a necessary option for a developer, however, if you do not care about your granular contribution towards further development of the app, try deselecting such options while setting up new apps.
5. Refrain from using external Memory Management Apps and RAM Cleaners. They tend to run heavy background services to detect memory usage and kill applications. Trust me, you would be better without them.
6. Try using black wallpaper and lock screen. Also, always select Dark Mode if any app has theme section. This makes the pixels produce less brightness and considerably save more battery.
7. Keep GPS Location off when not using any navigational/location based apps. When the GPS is ON, there are some apps that tend to acquire a GPS Lock even though they can work without it. Keeping GPS Off will not allow such apps to request for GPS Lock. GPS Locking is a battery draining process.
8. You can use certain tools like Greenify, WiFi Automatic, etc. to automatically manage application states or phone wireless to save some additional battery. Use these only if you are lazy like me. Otherwise you can always manually turn on/off wifi/bluetooth/nfc etc etc. Also, there are tools (like Juice Defender) which can enable/disable data connective at a frequent interval which results in really good power conservation without loosing push notification.
With applying most of these settings, I'm getting 6-7 hrs of screen on time very easily even when I've downloaded 1+ GB data and 40 minutes of video chat (hangout). Not to mention the usual gaming and application usage.:cyclops:
I hope that helps. I'll keep adding if I get any (without root).

Reserved for future use!

I'm sure you mean rooting and installing all sorts of battery saving items/tweaking.
Marely rooting wouldn't bring any difference to battery life for sure!

Just tweak brightness, make sure you getting good signal and use WiFi when available, don't leave Abby of the radio on unless not using it and that shall be good I guess

It's the icon on the lower right corner of the screen that says "Apps". Once you get in there find the app that you want to disable. Long press the icon of the app and drag it to the upper left corner of the screen where it says "Disable". Then when the "Disable" word lights up red just release the app into there.
Check out my screenshot for an example.

Please tell me a solution if any one knows:
I open facebook and after some time i close this application by click on list tasks soft key and close it. Immediately when I go into setting > application manager > running apps I still see a facebook process running. Technically i guess this should be gone i guess and hence any idea how to clean these which i guess can improve battery life.
Update: If I have notifications turned on in facebook then yes it can still run some process even after I close it in Apps Tab but I see the same with Samsung Music Player i.e after I close it I still see a thread in "Running" Apps.

These kind of apps do tend to run a background process to check for updates. Closing the app doesn't necessarily mean that the processes will close. And I'm not even sure even if you turn off all the notification services of an app, all the related processes will close for sure, it depends. Also, if you are using apps like facebook etc, do not worry much about the battery life if you have turned off the background data usage and notification services. It will have very minimal impact, almost negligible!

Auto-Force 90hz Using Tasker; Select your apps and enjoy

First thanks to everyone for their help on this small project.
This task will strictly run at 60hz, but once you select the apps you want it to run 90hz on it will jump up to 90. This will revert back once you exit the app you've enabled 90 on
Directions
-Once the profile is imported make sure it is enabled.
-Turn off smooth display
-To choose your apps tap on the profiles name -> tap choose apps.
-Once you have selected your apps make sure you save the changes by tapping the check on the top of your screen.

Yes it works, even on Android 11, I can confirm that. (Enable show refresh rate in developer settings, there you can monitor it the best) Make sure Tasker can access root.

Will this work with custom rom's or only the "stock" ones? Ie what is it changing to set the display rate? I have a tasker profile setup for this that uses Global `oneplus_screen_refresh_rate` but not sure that's gonna be available on an aosp related rom.
*update* Works great on my custom Android 11 rom on a oneplus 7 pro. Thanks Kevtrejo37
