hello

depends on which launcher you are using.

Native launcher on Froyobread its LauncherPro, and its does not have this function

A good launcher with this is GoLauncher
[Nexus S General] Nexus HAL:
Greetings! I've read all about not using task killers and refrained myself from using one. But now i'm a bit confused with the efficiency of android RAM management. I simply can't use my Nexus S smoothly beyond 100 hrs of uptime. after which the 'running' tab usually shows >200mb ram used with roughly 50mb of free.

I understand the used RAM was supposed to keep the previously opened apps in cache for faster subsequent execution time. But thats not what going on under the hood, i suppose, after 3/4 days of uptime. When i view 'show cached process' from the 'running' tab, it barely lists the default launcher and 1/2 other apps whereas this menu usually shows more that 10 apps being cached after a fresh boot.

The horrible thing that starts to happen then, most of the apps start exiting as soon as i touch the back button. Nothing except the foreground app stays in the RAM and everything else get dumped out of it and reloads at next launch.

Whats keeping the RAM then, if there's no space for app caching after merely 100hrs of uptime?

I'm not sure but the whole thing has led me believe my system has a major memory leak somewhere. Or, as i've read that the Nexus S actually have quite a bit lees than stated 512mb ram available for user apps… but should i expect this to be normal behaviour? Then why google released this model with inadequate amount of ram in the first place? I'm rebooting my phone every other night to keep it smooth!

Please shed some light, feeling totally lost. I'm moderately heavy user and come from symbian background.

PS: my phone is factory installed stock 2.3.4 with default launcher and widgets since i purchased if 2 mnths ago. no root done yet.
[Nexus S General] rentaric:
The cached app list in normal Android settings is inaccurate. Try apps like SystemPanel Lite.

Android does take care of RAM usage perfectly usually. Are you saying that your phone gets slower over time? That is quiet impossible unless you got a faulty installation of Android.

Also the "back" button does mean "exit and don't cache" for some/many apps.
[Nexus S General] italia0101:
Actually I agree my phone gets slow after time. I have to reset then after that it flys aagain
[Nexus S General] temp9300:
I noticed this problem as well, and i had read about it before, there are more people noticing it.

Maybe it happens only when you have too much stuff installed and running, if you are not a power user you might not notice it.

I think the android memory management is lacking here and the launcher app should be more robust, but the issue could also be solved if we had more memory.

I have 200+ apps installed in my nexus, some of them have services that run in the background automatically (and some of them didn't even have to, like some games and apps) and this uses memory.

I have around 15 or 20 apps always running as services, this uses 150mb+ memory. If i close any of these they will just start again in a few seconds automatically. The only way to stop this (my ns is not rooted) is if i uninstall them.

So, after a while, the most noticeable effect is that the launcher gets more sluggish and lagging. if i force close all apps it's smooth again, but only for a while. Also after i run a heavier app (like a game) and close it the launcher will restart/reload.

The workaround i found is to uninstall some of the apps/games that run as services until things get smoother again, but i don't want to give up most of them so i have to put up with a bit of sluggishness.
[Nexus S General] Nexus HAL:
Yeah.... my phone gets slow over time, kind of. Let me explain it...

after a fresh boot, i can browse, email, check facebook, make calls, send sms and then come back to browser to find my last loaded page still there. but after 2/3 days of up time, whenever i leave a foreground app and go somewhere else, it gets killed. the worst case i faced was, from the google search app, after inputting my query, it had to close itself before opening the browser to perform the search. it gets that bad.

during these times i usually face a slight delay and jittery animation while opening each app. and the cached processes usually shows only the launcher occupying ~30mb of space and 1 or 2 other very small apps. it appears, because of lack of RAM the system also stops caching the usual number of processes.

i've also thought that my installation could be faulty. i'm using it purely stock for the first few months to get the hang of the way android works. what bothers me, without even rooting it, how can can it get faulty. i even did a factory reset after taking it out of the box.

I'll monitor the situation with the SystemPanel Lite and report back. Thanks for the reply.
[Nexus S General] Nexus HAL:
This sounds exactly like what i'm facing. thanks for the input. I've also lost my launcher once after exiting the browser with several tabs open.. had to click the home button and then launcher again to get icons back on it. This usually doesn't happen after first 10-15 hrs but after several days of uptime.

I respect the way android tries to manage RAM automatically even by re-spawning the apps if it thinks they needed to be kept cached even after a force close from default task manager. With this kind of supreme automatic power comes huge responsibility of managing it well. It should count for every bits of data (concurrent garbage collection system?). But somehow it appears the ram management system is failing to count some of it and letting parts of the RAM go un accounted for.

I have like 30 apps installed from market with roughly 5 of them having active background process running. And I believe and hope this shouldn't be enough to take the android RAM management system down only after a few days of uptime.

Thanks again for the reply.
[Nexus S General] temp9300:
I'm going to try "auto memory manager" i read about in other thread as a way of forcing a minimum amount of free ram a bit higher than standard Android does.

It's one more service using memory but if does what is supposed to, maybe at least the launcher will stay more responsive.

The mild setting is too close to default so i have created a custom that looks roughly between mild and agressive.

I'll report back later.
[Nexus S General] AllGamer:
the phone gets horribly slow when the RAM drops to below 50 Mb free

in which point i always have to use task killer to kill them all, and it's fast again until it again reaches less than 50 Mb RAM

another thing i noticed is that with very heavy high quality pictures/icons loaded to customize the launcher it will slow down the performance

instead if the whole launcher theme is less than 2 Mb or less then the phone also works very fast.
[Nexus S General] Nexus HAL:
...and its unfortunate that i'm hitting the 50mb free RAM barrier with the stock launcher in only 3/4 days of uptime, regularly. why does the default app kill option let the memory go below 50mb then, if this can potentially hamper performance? and i'm not talking about any android phone here, but google's own Nexus flagship. :(

i remember reading a blog post by an android engineer explaining the merits of memory management by the OS and how task killers only worsen the situation. could they possibly optimize the OS ram management for light to moderate use and expected the heavy users to root and manage it on their own by tinkering the free mem settings? what else could explain the situation?

i wonder how things are with other skinned androids with similar hardware configuration if a Nexus is having tough time behaving well even with its trimmed software package. and i consider myself as only a moderately heavy user.
[Nexus S General] Ok_Kaleidoscope5109:
the memory cleanup isn't perfect in Android.

As much as everyone likes to say that Google tells you not to use task killers or any thing and that Android can take care of itself, every nice ROM out there plays with the minfree settings.

Fact is Android isn't perfect.

I know this from a 256MB device. We set it to it could boot with 30mb free. You could do maps and stuff, but a day later Maps would crash left and right because you ran out of memory. Even if it said 30mb free still in About phone.

The same with the Nexus S. Stock settings allow little free memory. I saw this in CM7. It gets slow after a day. A reboot fixes it all.

I suggest tweaking the minfree values or something so you can get decent performance. Fact is that performance will drop off a bit with up time, but at least if you tweak your minfree settings it should last a LONG time without needing to reboot.
[Nexus S General] demo23019:
this works great after patched my phone never gets slow

http://xdaforums.com/showthread.php?t=1111145

just an FYI if you try it dont use the CWM version doesn't work on NS for some reason at least it didn't for me

just manually move with root-explorer and set perm to 777 and enjoy

edit

OP not rooted this requires root
[Nexus S General] Nexus HAL:
thanks for the informative reply. i've started to get the point about the situation. maybe a little more RAM would've delayed this kind of clogging but at its current state our little green robot simply isn't mature enough to carry the load we're putting on its shoulder. it that case i would accuse google of spreading the word that manual intervention isn't necessary. thats simply misleading. they way they've programmed the stock rom appears to be optimum for light use only.

anyway, i guess re-adjusting the minfree values require root, right? i should better start reading up on rooting then.
[Nexus S General] Nexus HAL:
i'm thinking of learning about rooting now. i like android for everything else it does and this particular device got me hooked with its unusual and clean look, and i don't wanna give up on it easily. but i think i'll have to gather up a lot of knowledge from this forum pages before i can attempt something like you've described.

thanks a lot for the solution anyway. i'll try it as soon as i feel comfortable with my understanding of android internals.
[Nexus S General] demo23019:
its not really that complicated just a script file you put into /system/etc/init.d with Root Explorer and set full permissions with root explorer and reboot and it starts working and if you dont like or dont want to sue anymore you simply delete the file.

but yea get rooted definitely worth it and you will gain more knowledge
[Nexus S General] temp9300:
well, things didn't exactly as i had planned, the test with memory optimizer was going ok but i only did for a day.

After that, i managed to sell my Nexus and went for an SGS2!

So far no lag/sluggishness issues and i have installed most of what i had in the NexusS, this phone has 2 important advantages, it has double the ram (so it should take longer to fill) and also it's faster which might compensate.
[Nexus S General] window7:
Dun use the script if you're running netarxhy, mathkid95;16006240 or trinity kernel. It will just made you worst. Oh yea, and also dun use it on Brainmaster miui rom :p
[Nexus S General] king23adrianc:
really?? but simms22 use auto memory manager too.. so i think we can still use the script with trinity kernel
[Nexus S General] simms22:
auto memory manager and the script are two different things. honestly, i havent tried the script because auto memory manager works for me. ive been setting it higher than the aggressive setting lately btw...
[Nexus S General] crowbarsolutions:
As a developer I've had to deal a lot with Android's memory management. Simply put, Google is correct in saying that Task Killers do more harm than good. Android is pretty smart about clearing memory.

However, a lot of apps and even some basic framework level calls cause memory leaks, which the garbage collector can't clean. So the only solution is a device reboot.
[Nexus S General] demo23019:
I use matrix, and worked fine on netarchy when i was testing.

and Brainmaster MIUI ROM already has script so yea dont need with his ROM also he provides trinty kernels on his ROM page so if trinity had issues with ram script i dont think he would be providing download links to use with his ROM

Best thing ever!

Use option 9 which is MegaRam 2 and then use option 12 which bulletproofs your launcher.

You will never experience lag again :D
[Nexus S General] Nexus HAL:
thanks everyone for stopping by...

are you guys talking about the auto memory manager by mad squirrel thats available on market? if yes, can anyone confirm me whether it requires root or not? as far as i gather, it adjusts minfree settings, which is supposed to require root. but the free version of the software says it doesn't require root and the premium version says root requires!

as i'm new to android i've avoided rooting so far in fear of messing things up but it appears, the stock rom itself is somehow messed up when it comes to memory management, or some rough app is fooling around. so i might end up rooting it anyway. but for the time being, a non-root solution, if available, would help tremendously.

by the way, i disabled the facebook notification, and currently on my 3rd day without re-boot. it eased the problem to some extent i must say.

[Galaxy Tab 10.1 General] lordwinkevin:
I had an unlocked bootloader but after going back to stock OTA 3.1 and an OTA update (not touchwiz, i thought it was) my bootloader is now locked.

I dont have the unlucked symbol every reboot.

I also noticed a video app on stock honeycomb that stores rented movies and personal vids.

I am charging my tab right now to get TW cause i think it needs to be well charged before getting the OTA.
[Galaxy Tab 10.1 General] MrSewerPickle:
It does indeed lock the boot loader on unlocked tabs. During the update I noticed in the preboot/apply screen it said "Encrypting Bootloader...."
[Galaxy Tab 10.1 General] pokey9000:
I have yet to get the update, so I don't know the exact flow... but it sounds like this happened somewhere between the update finishing downloading and the reboot to apply the new update, right?

Or did you see it on an all text screen with something that looked like:

----- Start to Encrypt BCT&Bootloader -----
[Galaxy Tab 10.1 General] MrSewerPickle:
Yep, It was on the download mode type text only screen in the top left under "Odin Protocol v1.somthing"

Similar to what Ive seen on CWM type flashes before....It was written out briefly then some other items followed it then the tab rebooted.
[Galaxy Tab 10.1 General] pokey9000:
Thanks! That confirms my suspicions that the fuse setting gets done in the bootloader (where ODIN lives).

Hi @all

I have a lot of HTC Flyers 3G, I would prepare for co-workers. For that i would like to set policies for the users, like lockdown apps market, prohibit to change themes, and a lot more.

I need to modifie the device and lock it completly down, the Users can only use the WLAN, 3G, CAM and the configured apps on it.

Is there any apps where i can modified these settings, have anyone a good manual how i can realize. Or is this not possible ?

thx

galbur
[HTC Flyer, EVO View 4G] Farsquidge:
You will have to root the devices then create an app that is locked down to whatever you require and runs at boot to replace the generic Android UI.

If you do not have these skills, then you will have to contract a SW Developement company to do this...
[HTC Flyer, EVO View 4G] Elim:
Like my previous writer say: 1. You have to root (S-OFF, perm. root) because you have to change system settings.

2a. After this and with a little unix knowledge you can configure the system, remove APPs etc. You have to done this once, then make an backup and flash this backup on the other Flyers.

2b. Or you build your own custom ROM. Here in XDA is a kitchen to do so but also here you need enough knowledge and experience with Unix.
