[Q] Forcing apps to stay in memory [ICS] - Nexus S Q&A, Help & Troubleshooting

Hi
I know this has been asked before but there is no reply to it anywhere.
Is there any way to force an app to stay in memory in ICS? Many apps seem to shut down when u navigate away from there sometimes even for 5 seconds to quickly check say facebook/twitter/sms/whatsapp.
I did not have that problem with Gingerbread...?
Any ideas guys how to force the app to stay open in the background no matter what?
Many thanks

gps bug?

Dont know if anyone else has noticed this but has happened to me a couple of times now. If I start up an app that uses gps i.e speed test then when I quit out of the app the gps symbol remains in the notification bar flashing. I dont know how to get rid of it and have to reboot my phone. Any ideas guys?
Is it possible that your app is still running in the background even after you quit? Some apps do that.May explain why gps is still running.

Hi. Yeah thats a possibility and have been thinking it through. Take for instance speed test, it has no exit key so you have to quit out of it by either clicking back or home. Maybe that is where the bug lies and its nothing to do with my nexus.
One other question I have if you could help me out is about multitasking. Say if I hit the home button when an app is running it still runs in the background. How long does it do this for with out resorting to using an task killer or similar?
Cheers

This problem is not unique to the Nexus S. I actually haven't seen it on the NS (yet), but I see it routinely on my SGS i9000.
You should be able to easily get rid of it by just turning on and off the GPS with the Power Control Widget. No need to reboot. Turning on and off Location Services in Settings screens for the phone should also do it for you.
Thanks ill try turning it off using the location settings next time it happens. I did try with the widget but when i turned it back on it returned and was still there.

From my VERY limited experience, some apps stop running as soon as you press home screen (e.g. website/forum apps), some you need to specifically exit the app (if there is an exit option), and then there are others that stay running until you force stop it. Seems like it depends on the design (or mis-design) of the app.
You can view what apps are still currently running under Manage Apps. You can also manually stop those processes there if need be.
Hope this helps.
Thanks. I've tried looking under manage apps/running apps before but the task I think the gps bug is coming from is never listed in there. Infact not a great deal gets listed in the standard gingerbread applications settings. Games that I know are still running in the background dont get listed either for some reason.

[Q] Nexus S suddenly very slow - error message

I love my nexus s, but suddenly the OS became very slow and I need help on where to start the trouble shooting.
It is the entire operating system -- even the touch screen.
I will pull down the notifications window and it will get stuck,
The browser select screen will pop up when I click on the "world" icon to open up the internet and after I select browser, there is a long pause before the background color appears (recognizing that I selected which browser) and then there is another long pause after recognizing that I selected it.
I have installed apps from other sources besides the android market.
At first I started thinking that I had too many apps running, so I started using the apps manager to force close the apps, but that did not help.
I tried restarting the phone multiple times with mixed results. Sometimes it would help a little, other times not at all.
I looked at how much room I had left on the internal drive and started moving more to the USB drive -- that didn't help.
I started wondering if I installed too many apps.
Then suddenly, when barely chugging alone to try to update a few apps (literally the install part was lagging -- not the download) I got an error message:
Error: Activity Android System(in process system) is not responding
It's funny -- when I want to replicate the error (as in right before writing this post - I cannot).
Thanks for your help on this matter.
Please instruct me on where to start trouble shooting.

root or no root?
no root. Thanks for fast reply.
my hunch is that an app was screwing something up.
There were a few that I wasn't updating because I didn't like how they started changing permissions. But maybe I should go through and update every app that I can... thoughts?

update is good. there could be an app freaking out holding up the system.
And at the worst case scenario you can do a factory reset (menu, settings, privacy) and see if that fixes it... of course you'll need to re-install your apps afterwards

I don't know how to check what launcher I use...
I don't even know what that is

try updating your apps. a factory reset will help, but that should be your last option. launcher apps replace the stock launcher, the thing you press to open the app drawer and that holds the phone app and such.
My phone was acting all sorts of crazy lately (couldn't connect to the internet amongst other random performance issues) and it turned out to be an app causing the problems. It was actually one of two apps. It was either Tetris or memory trainer. I deleted them right after one another so I'm not sure exactly... Just a heads up to be cautious if you're using these. For the record these apps were from the official Android market.

apps not installed error, gps problem

Hello guys
i have a stock rooted uclb3 infuse, and my problem is some times when i restart the phone most of the apps names become com.xxxx.yyy(x&y are names) and when i press them it says application not installed....all my apps installed on internal memory....
its happening frequently to me, and i almost had to restart my phone 5 times to get my apps to work... so what must be the problem and any solution???
one more problem is the GPS, my stock settings dint work fine for me, so i changed the server settings to nokia and i get a lock usually withing 20-30 seconds but the problem is it looses the lock after some time and then it takes lot of time to lock again, annoying while voice navigation.....

There is a thread in the dev forum with addons to cure the non scrolling wallpaper bug

data control

Hey guys, i would like to do the following. On monday-friday i would like to have my data off but have it turn on automaticly every hour. Another thing that i would like to have is to have data turn on whenever i launch app like chrome or email and have data turn off when i close it.
I know how to make a schedule for data on-off, but im having trouble finding a way to have data on if certain apps are launched. Help please.
Thanks in advance
Luke
Tasker, maybe? I've never tried to do something like that, or really had the desire.
Just curious, but why the desire to switch off data? Also, you would have to force close apps like chrome all the time due to how Android handles multi tasking.

I would like to have this ability because i only get one signal bar at work which kills my battery, right now i turn on and off data manually which is ok but i would like to have this done automatically if possible.

How to keep Apps running in the Background?

Hi everyone, ever since the update, my apps stop running in the background when I close the app. Example: I don't get Whatsapp notifications anymore unless I open the app and keep it open. If I close all open apps, I will no longer receive any of the notifications for any of them.
I went into the battery settings disabled battery saver mode but that didn't do anything.
I would appreciate any help you could provide.

It's apparently one of the issues with the latest OTA update, where closing all running apps will terminate the background processes associated with the apps closed. Prior to the update and the Close All button being added to the recent apps list, I don't think it had this problem (I don't use Whatsapp, but my Skype and Discord notifications still come through even if I don't have them on my recent apps list).
This is a little frustrating. Noticed that I wasn't getting any notifications from tasker, pushover, textra, hangouts, inbox and etc.
Also noticed that pushover will not update unless it is off of wifi. All my other devices receive notifications on this wifi. IE nothing blocked.
I have had to open all the programs that I want to receive notifications from, open. Not the best work around.

I noticed that on occasion there will be small text under the new button that says "long press to set up apps that could run in the background" I do it but it doesn't seem to do anything, maybe free up some of the RAM but that's about it. I'm wondering if there is a bug and if it's supposed to show something.
Has anyone else tried the long press?
As of now all I do is keep a folder on the desktop labeled background apps. It helps big time when I accidentally tap the close all button. But my solution as of now is to keep things open that don't seem to work in the background. I've been experimenting with what works and it seems like in some recent app updates they begin to work without being open. I know for sure that facebook and now facebook messenger work without being open, as well as some google services. I have a memory clearer app that I use when I'm not using my phone so it clears whatever it can without killing the apps. But that's what I have as of now, trial and error to figure out what I need to leave open and what I can close. And I strongly recommend the folder, I have had many times where I accidentally close everything and forget what I had to leave open.
It's a bummer though, I just bought the phone and then this update came out. Kinda kills the excitement of getting a new awesome phone if I have to deal with this frustration :/ Other than that, it's definately a nice step up from a Samsung S4.

does it misbehave after rebooting? or all the time?

Misbehave as in not show anything after a long press?
Yes, nothing happens anytime I try it. After reboot, the first time I pull up the running apps is when I get the prompt. After the first long press after a reboot, the prompt is gone. If I have an app open and then I do the long press, I am taken back to the desktop, but no matter what I try, nothing seems to happen after the long press other than being taken back to the desktop if I had an app open.
I have the same issue, I thought it was a Internet connection issue (see my thread) but after digging deeper realised my background apps werent running after closing them and the long press option does nothing.
I have the same problem. Any solution?

I've just installed the new update and it looks like the issues I had with background apps closing when clearing all apps has been fixed. I've got no apps running in the foreground yet can see Whatsapp, Fitbit, etc still running and I'm receiving notifications for them.
