Is there a way to stop android closing certain apps?

Hey,
I use an app called 'itching thumb' wich replaces the default home screen. But as the app is only intended to switch task I still use the defaulft home screen (sense). The problem now is, that this way 'sense' is sleeping and since it has a high memory usage it's often closed by andoid. My question now is, is there any way to let android prefer other apps to close?

App closes on screen off..

Recently, I have been facing this problem of app closing when I switch off the screen by clicking the button on the top..
Besides, app also closes after a few minutes of non activity when the screen is still on..
Please help me out...

Hi there and welcome to the forum!
If you'd like to get help here maybe you should provide few more details. For starters let's begin with your android version (which ROM do you have on your phone and how it's installed) and give some examples of apps that FC.

Apps closes when re-opened

Sorry for the vague title.
When apps that require additional data (GTA III, Spectral Souls, ect) are downloading, I find that I need to keep them running in the foreground.
If I open GTA III, let it start downloading data, switch to home and do other stuff, then switch back, the app immediately closes and I have to resume the download by relaunching the app.
I am not familiar with downloading data for apps so I am not sure if this is expected behavior or if there is some issue with my tablet.
Thank you in advance.

I have experienced the same issue.
Also even when I play a game and go to the home page to look at something and try and get back after a few minutes the game restarts.
Its as if multitasking does not work or the applications are being killed.

One of new features in jelly-bean is closing non used apps automatically instead of keeping them in ram
like android does normally, to controll dfault system behaviour in this case go to setting/developer options/keep activities, this may be causing problems, from developer point of view every app should be killed when user quits is., and android activity life cycle was sometimes real pain in the ass, especially in case of porting apps from other platforms.

Thank you for the response. But this is not true multi tasking then. And what is the default standard limit mean? Thank you.

lol apps dont close when you press the home button smart one. and op if you click the multi-window button(the one on the right of home button) you can swipe them all away really fast but dont really know about all at once

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.

Spam on my android phone

I have a note 2 and maybe a long time ago I downloaded apps which might have caused a problem on my phone and I thought I removed the apps but the problem is still there months later.
Basically random apps are added to my phone. I don't think they are actually downloaded to my phone because I can't see them in my app list but over time it's clogged up all my free home pages with icons for the apps. Now that all the space is taken it will say no space for shortcut.
I'm not sure how to get rid of this problem. Help please?

I use to store application to Samsung Kies

From what this sounds like, you have shortcuts on your home screen that are to non installed apps. Try pressing and holding the app until a menu comes on the top of the screen, keep holding and drag it to either "Uninstall" or "Remove"
I hope this helps

Id say back up what you need and fctory reset.

Assuming these arent just latent shortcuts and a bad launcher....
You could, try avast (incase it virual); you could remove all non - essential apps one-by-one (I would start by opening the playstore and looking at your apps to find the ones with the lowest reviews, read the comments.); you could try a new launcher and forget about the old homescreens, if these appeared there you would know something is afoot.
