I have a 0.5GB ZTE Cheapo Android JB phone. I kill apps using Advanced task Killer and then they start a few seconds later. As a result, I have constant low memory notifications. I've us d Manage Apps to look at the apps in question e.g. Viber, Line. I've moved the apps, when I can, to the SD card. I notice that there is a 'Launch by default' parameter, but it's grayed out for the 'naughty' apps. Why do these apps keep re-appearing and what can I do bout it? PS I've tried rebooting but no improvement.

Hi,
I installed Advanced Task Manager and after killing all running tasks, there is only a little of RAM amount available, around 130MB. So is it normal for a 512MB-ram-powered device or should I call the service?
Thanks
Tasks will still auto start, depending on what they are. I suggest firstly, to get a system monitoring software to know who consume the RAM. I use "Quick System Info".
Once you know who the consumers are and if they are not useful always, but still restart even if terminated them, probably uninstall them.
But if still you want them there but not really running all the time, then its time to be rooted, use "Autostarts" program to control them (ie. stop them from auto starting). If they are system files (ie. cannot be uninstalled by Applications Manager), use "Titanium Backup" to backup and uninstall them.
I use 200MB swap file and 98 swappiness setting in Urukconfig.But it use RAM in most time and seldom use swap.Is this because the Swap file is in internal storage but not in a fast SD card ?I`ve got a micro SDHC (class10) 4GB and I want to format it into 2parts.One is used as swap partition.The other one is a FAT or NTFS filesystem.But I don`t know What is the name of the 2 parts in /dev.One more question,can swap partition be a EXT3 or EXT4?
Thank you for reply.My English is not good.Sorry~~
What did u use to "measure" the free memory? How does it affect u?
In general u have to know that android does not have the windows like "free memory" as it tries to keep as much apps in "background" as possible. To load em faster at next startup.
Many programs have the strange behaviour to have several listeners to startup every once a while or they even load at startup. You can check this with "Autorun Maganger"
With "Task Manager" you can see what apps are currently running. You will be surprised what apps are loaded right after startup - even u never started em
Anyway having "low" memory at runtime isn't to bad normaly - as android will kill unused apps to free memory if needed. Just if the value is permanent under about 35MB the system will get sluggish.
Regarding your swap: "I use 200MB swap file and 98 swappiness"
Sounds heavily wrong to me. As the CPU will be permanently use for swapping apps and will slow down your device meanwhile...
The problem of android and swap is that active processes (like widgets, services, the running program) can't be swapped. Swap just gets u the ability to hold inactive apps in memory to load up faster at next startup. (if u want to know more about it read about the "life cycle" of android apps on google) But since they are on a VERY slow memory compared to RAM the reload process actualy isn't that much faster...
Try reading the Tweak guide in my signature to learn more about memory management.
Before, I got the same issue like this so I used Autorun Manager to manage some auto startup and backround running apps but It didnt work. Now I find an other solution. That is TiTan Backup Pro. I use TiTan to freeze some apps that always appear in backruond running apps like Market, Fring, Textfree...
Although It takes more time but It may save the battery and ram. Dont worry about the next time when u need to use these freezed apps because every times u freeze an app, u can defrost it immediately. So that app will not run at backround until u run that app again.
That the way Im using to save battery and ram

Yeah thats what i use to do - but u have to check with autorun manager before to know wich apps to "frost"
Thank u very much
256MB RAM is too little.
Hey guys, Wanted to know if someone could clarify the difference between active applications, running services, system storage, and app cache. I understand that active applications are apps that are left open (usually what happens when you press the home screen to leave the app) and that closing these apps clears up LOTS of RAM. I also understand that running services are the background processes that some apps use and that closing some of these are pointless cuz they will just start back up again. My question is, are all these categories eating away at my RAM? Does clearing up Cache also free up RAM? Are apps that are downloaded on the system storage also eating up RAM or is system storage a completely different thing? Sorry for all the questions, But I am hoping someone here can give me a clear explanation or breakdown of the things I just listed. Thanks!

It's not a PC. It's not Windows OS. Stop worrying and let Android manage it for you. Relax and enjoy your phone.
Hey...not sure if this has been answered before or not but im trying to figure out battery draining issues and one of things ive always used is ram optimizers...I have Android Booster and Android Assisant ....and then i also use the built in task manager to clear memory...shouldbi be using these apps or are they draining the battery by running in the background? They seem to clean up a nice amount of memory....and keep my phone running fast....just dont know much about them...

I do not think that by cleaning your RAM, you can reduce power consumption by RAM.
Actually, you do increase it. Android itself closes unnecessary applications when needed to clear memory. But, when you clean memory, either by task manager, or some custom tools, you are basically forcing applications to close and restart unnecessarily. I would say, it is additional load on CPU, and thus on battery.
For most applications, exactly startup and finish times are most expensive in terms of CPU load and battery. And most well-designed applications will not drain your battery when paused.
Reminds me of RAM cleaner programs for Windows machines, that would simply trigger excessive page faults.
while i agree with most of what you posted, there are 2 major flaws in your logic:
1. you talk about closing apps that restart on their own, but not many apps actually do that. sure, widgets, services, your launcher, communication apps and syncing apps need to run in the background, but certainly there are other apps eating away the battery, that need to be fully closed, when not needed. kies air or wifi file explorer come to mind. some of those apps don't fully close through the back button and must be killed from a task manager to save battery.
2. you say apps are paused. that is not necessarily true. many apps are capable of fully running in the background, after all, we are talking android and not iOS. we have full multitasking and apps are not generally suspended. say, you want to play a game for the first time and it needs to download more data. you can do whatever you want with your phone, open a dozen other apps, browse and listen to music, that download will continue in the background. this might fill up the ram over time, if you never close an app or apps do not allow direct closing.
there is a reason why samsung supplied the phone with a built-in task manager.
some apps are not well made and don't quit properly and need to be killed that way and killing off unnecessary apps (that won't restart) makes sense.
and let's not forget apps that get stuck but don't force close. they need to be killed as well. what else are you gonna do? restart the phone? certainly that wastes way more power than a restart of a few services.
every time you have a look at the samsung task manager or the "running" panel of "manage applications" and you use 500 something MB of ram and kill all apps, it will go down to something like 200 something, then the services restart and you are back up to maybe close to 300 (all numbers vary on your rom and apps). given that situation permanently saving 40% of ram is certainly a good reason to kill apps before you put the phone in your pocket.
I guess, then, it is best practice to kill all apps from task manager, a few times a day, especially after using several different applications and closing them. Applications that are needed will be restarted automatically.
I am not sure about running so called "RAM optimizers" constantly, though. When you are using your phone, it simply introduces more lags. Otherwise, it does nothing, if you have cleared RAM after heavy usage.

killing itself is not necessary in the 1st part.
the more the memory android uses the better the apps behave, thats how android is desinged.
if you people still want to release some memory just use the samsung task manager ot clear memory or "fast reboot" from market.
Thx for the posts...i deleted the 2 android apps for now to see if theres a difference...i will trybusing just the built in task manager for a few days and see how that goes. But for example i mainly use my phone for words with friends...facebook...twitter and instagram....when i run the built in task manager it frees up mabye 200mb of ram....then i would run android booster which would clean up another 200mb and would close stuff like facebook...and tweetcaster and so on....the built in task manager doesnt seem to pick up on and close everything it should...which is why i downloaded the others...my phone has 800+ mb available and i usually find that ots using 500 of those 800 at all times...i wouldbfind myself constantly closing stuff with the optimizers...but like you said...they just open up in the background again anyway. Im rooted and have got rid of all the safe stuff to get rid of and the funny thing is i still dont see much of a difference in ram consumption...i think of ram as important cause it keeps things running smooth with no lag...not sure what to do i guess...ill try it like this without the optimizers and see how things go and download them again if i get bad lag...what i really need is a actual list of my phones internal software so i can get rid of the rest of the unneeded system files...ive found similar lists..but never a list of my actual phone...theres certain stuff running on my phone that isnt in the lists ive found so i left them with the worry that i may have to reinstall the rom if i delete the wrong thing...im also a android noob...only 2 months of using it so far so ive got tons more learning to do...thx for the opinions tho...keep em coming if you got em!

hi all,
i have the V30+ and it sometimes closes apps for no reason, examples:
1. playing candy crush and then i get a watsapp message, i go to watsapp and answer and then go back to the game and it reloads, the game was removed from memory.
2. driving with waze while the screen is off (using sound only on long straight roads) and it just closes.
any ideas? is there a setting or something or is it a bug?
In recent apps window you have little pin and you can pin an application that will not be closed.
I've noticed the same thing. It almost seems random. Sometimes I'll tab out from Pokemon to Discord and tab back and the game will have closed, sometimes it will still be running. I have set the battery settings for power saving exclusions on certain apps and those apps are still randomly closing. I am wondering if there is another setting somewhere?
I don't like the pin option because I want to be able to manually close the apps as I need. If I un-pin it to manually close it, I have to remember to re-pin it next time I open it to keep it from closing unexpectedly? This is also assuming that the pinned app doesn't close in the background anyway.
Pinned apps are still closing when in background. When opening 'recent apps' the app appears to be still there, but when selected it has to reload from scratch. Something is killing backgrounded apps.
bump. I also have this issue. I would like a fix
have exactly the same issue. Power saving exclusion ON for an app. Switched to another app such as browser or whatsapp, switched it back and the app that excluded from Power Saving was killed.
Mine is a H930DS with 4GB ram. When looking in Settings > Memory I usually have less than 900MB free. Is it a normal free memory level?

Android is designed to use 100% memory.
