apps not always opening from app drawer - Galaxy S II Q&A, Help & Troubleshooting

this is my first android device so i don't know if there's a history with this problem but, as the title suggests, i sometimes can't open apps.
when i click on it, the app will start to fade as if launching, but that's it. i'll keep clicking it and it'll just fade in and out. i have to exit the app drawer and go in again in order to open the app. it's increasingly happening more often now.
anyone else have this issue?

[Q] recent app button

does anyone know how to clear the recent apps so there is not a long list? is there anyone that I could shorten it to only show my last 3 apps?
thanks again

If you hold your Power button down a while, a list of options will come up. Select Power Off. This will power down your tablet. When you restart it the list will be cleared.
What type of things do you have on your recent list "sexfreak"?
there are things there that are adult oriented, I also dont like how it shows the last picture taken. I was hoping for something a little more slick then powering it off and on, like maybe shortening the list that it would display, or a "app" or link that would clear it out.

Just use one of the Task Manager apps then kill all the processes.
i use advance task killer, it free's the memory up but still leaves the "history " should I use a different task killer?
Developers can mark their apps to not show in recent apps list, but the list itself is only modifiable by android OS. So I think there is no a task killer/manager which can help you.
You can reboot tab or open as many app as needed to hide your problematic app from the lsit
So far Task manager will not clear your recent app list. Only solution I have found is rebooting the device.
Does anyone know where the data is stored? Would it be possible to navigate to the location of the file and clear it that way?

has anyone noticed that after you kill an app that it will start on its own? gmail, books, clock, browser, craigslist, google voice and others will start up after I "kill" them

How to close App

I have ICS 4.0.3. and I want to know how to close App?
How do you know for sure this App is closed, without having to go in Settings and close it there every single time manually.
You don't.
Android handles management of apps and will close them when it needs too. It will also pre-launch apps so they are ready to use. So no need to worry about closing them. Just go back to the home screen or whatever and don't worry about it.
If something is misbehaving you can go into your Settings > Apps find you app and hit Force Close, but that should not need to be done often. If you do then find a different app.
Even if you do this to "close apps" Android will probably just relaunch them in a few minutes anyway. You just don't need to "close" apps. That is a traditional PC convention and does not translate to Android.

Click on recent app tab, find the app that you wish to close, swipe left or right to close it. Love this feature so much.
Open the recent apps button at the bottom (3rd from left and looks like 2 boxes) and then swipe the app you want closed to the left or right.
Edit: Crap. Lol someone beat me to it

Pretty sure that is just a list of apps you opened recently. Swiping them off just removes them from the list, and doesn't stop the application from running. You can test this by swiping it off then going into your Settings > Apps. For me, the app is still running even when swiped from the list. Also things stay there even when an App has actually been forced close.

Correct this doesn't close the app but just gets rid of it in the list of recent apps.

LOL. Yeah, when I first saw this I was kinda confused by it. I know how Android manages memory and apps, so I didn't understand what it was for: especially with prominent placement on the System Bar. I guess they just felt they needed something for people used to closing apps.
This would be great for people that run 3 or 4 apps all the time since they would not need to have them on the Home screen or go to the App Drawer.
Android does a good job managing memory, so you should only need to close apps that are having problems. This can be a hard transition from the Windows world.

Now this isn't necessarily true.
I played w/ this a bit and put the Task Manager widget on the home screen. On some apps, if you remove them from the recent apps list, the task disappears from the Task Manager maybe 5-10 seconds later. Now while I realize that not all running apps necessarily show up on the Task Manager, I've noticed that if an app/process is ended on the Task Manager, it is no longer listed under running apps in the settings.
And when you use the Task Manager to close certain apps, they'll still show up in the Recent Apps list but instead of showing a proper image of app activity, it'll be just a blank black square. When you tap that square, it just opens the app as new.
I used the app called system to verify and swiping does close them....awsome.

My life is changed forever

I just discovered that you can get rid of apps from the recent apps menu (the square button next to the home button) by swiping them to the side. I don't know why this makes me so retardedly happy, but I am sure that SOMEONE else out there will also appreciate this tidbit of information.
Anyone else have any nuggets of joy to share?
I liked that trick also when I first found out. Another thing too is that you can hold down the app in recent menu and a quicksetting will come up to let you remove it from list or look at app info.
Remember though, this only removes it from recent apps list. It doesn't close down the app itself.
Does it really matter though performance wise? I Always thought Android puts background apps into an "idle" state where they dont take up any resources until used? Although it is cool for people with OCD like me

Yes it does close the app. It just doesn't close background processes of the app.
Swiping an app from recent apps menu removes the app from cached memory, but keeps the background sync's (if it has any) still running. So you can kill off Facebook, but it's background sync (that would be started during system boot up anyway) remains.
You can test it, if you swipe browser from recent app's memory, it has to reload the page it was on. Same with Facebook app. But Facebook app's background process keeps running until you 'force stop' it.
Android application architecture runs in two layers, foreground and background processes. UI and the things you can use are written to memory when focus is lost from those apps, clearing them from recent apps also clears the memory those apps take at the time.
Is it useful? Yeah, for some things. But it won't improve your performance in any real noticeable way. Best you can do is swipe away apps that you don't need, keeping only apps that you want to keep in memory should you re-open them again. But that's usually too much micro-management to be worth it.

Perhaps, BUT, not every app in the recent apps list is actually running. That's why many times (most of the time?) the screenshot isn't what you actually see when you select an app from the list--you're really restarting it.
I think it's safest and easiest to just assume that you're really only removing apps from the recent apps list, not actually managing what's running in any way.

Yeah it doesn't make any difference performance wise, but it makes the menu much more useable for me =D
Thanks for this message, this is my first android device and I've been trying to figure out how to "close" applications. Did a search in here (I think), prime manual search and googled it. I am slightly OCD and like to "close" thinks that I'm not using. Harkens back to my early Windows days when you closed apps to conserve memory.
In the manual it says to close application by clicking on an X in the recent apps menu. Though unless it is super tiny, there isn't one.

if you have the dock, 2 finger gestures on the touchpad act as screen swipes. i.e. swipe two fingers across the tab, the tab changes screens. Also, if you want to actually kill the apps, add teh asus task manager widget to a screen. works great!

That was an ASUS Honeycomb customization. It went away in ICS...

that's what I meant. I should of been more clear then. just swiping it doesn't close down app "Completely", meaning no background process either. you have to use a task manager or Force stop in order to "Truly" close n stop an app from running.

You know.....that Asus task manager widget does not work on mine. It doesn't matter if I press x next to one app or select kill all - nothing happpens. I think mine is broken
I removed it from one of my home screens, no need to have it if it doesn't work

It's a bit different though, because those background processes will (likely) already be running even if you don't start the app. Most of those background processes are started by boot activity in Android and others are started by scheduling activities (such as alarms or certain notifications and sync). These will be usually restarted once app is started again too (after Force Close) and if they are not already running (and they usually are).
Force Close is unnecessary unless you know that a certain app is bad for the system and was run accidentally, etc.

App keeps refreshing

One of my apps (Airwatch) keeps refreshing / opening from scratch when I launch it. I tried locking it in the recent apps dialogue, changing battery optimisation to "ignore", and also changing Launch Control to manual and allowing all three options.
Any ideas in what else I can do to make the phone keep the app open in the background? I use it all the time and it's quite annoying having to wait for it launch every time I need to access it.

fastest way to force stop an app?? help please

what is the fastest, easiest way to force stop an app ?? i know settings, apps, find app, but with a bunch of apps its a pita. any other tricks, shortcuts, safe apps, or any other ideas?? not looking at hiding the notification, but stopping the app.
say 2 things, new to oreo and s9, last phone was an s7. anyways, if i had a program running in the notifications, say for my motorcycle gps, tomtom, i was able to long press the notification, then go to app data and force stop. not seeing that anymore.
Trying to find the fastest way to force stop an app running, that has a notification. for example this one says connect device. I am not trying to hide the notification, but force close it when i don't want it running. for example this app gives me live traffic, sometimes i want it, sometimes i don't.
thanks much for the time
settings, developer options, running services
that seems to work too, and the app i want to end is on the first page.
seems easier than the apps, and scrolling down to the Ms
hmm
Greenify, then you can set what you want to force close, and then make a home screen button. Bam it easily blows them away.
Recents, long press the app icon on the left, wait for the i info letter to appear on the right, press i, force stop.
You're welcome

world be nice to find an app that shows ALL opened apps and services and can completely close it in one click.
thank you so much!!!!
I just moved from s7. on s7 android 7 I can long press shortcut on home and can tab on i icon That menu has removed.
The apps you actively use are closed when you swipe them away in recents. You dont need any fancy force closing. Try it. Open recents, swipe away the app, when you open it again it loads from scratch. Or am I missing something?

That not correct. Some application even you remove it from recent app it still run in background.
In my case Facebook Messenger is often cause media sound issue, after end call sometime media sound route to earpiece. Two way to solve that is kill the app or restart phone.
You can use my apps Killapps and Hibernator
