[Q] android does not automatically kill apps - Android Q&A, Help & Troubleshooting

i have my lenovo p770 and its been a month since i used it,
my problem that ive encounter was when i have a low ram the android cant even kill apps on its own to free ram for the apps the im gonna use. is my device defective? it forces the apps to crash , i asked the same users with me but they dont experience it. theres a solution to my problem, it is to restart the phone. but i dont want to restart it over and over again. i hope somebody can help. i try to search many many times but cant find solution. thx.

clarrification
my problem is unlike what u can suggest. that android will just free ram when needed to run a certain app. it forces the app to crash and the launcher a lag.here are some picts of it. i reset the phone several times monitoring it. even without games or whatsoever. it keeps increasing constant and hard to decrease it. in a purpose of casual use.

[Q] Help - Phone reboots ramdomly

Hi all,
Need help with my phone
I have the this problem that it reboots ramdomly
I tried various roms and still the phone reboot ramdomly
Please help because dont know where to look.
Now i have MIUI Rom installed at the moment
Here are some possibilities. Hope it helps.
1) Perhaps the mobile is too hot. Check the temperature (you could install a app to do it, like TempMonitor Lite). The X10 loves to work below 42° C (colder is better).
2) If the bug happens after you install your apps, perhaps your apps are using almost all the memory and the system can't find enough to use. Maybe you have a faulty app. You could uninstall some background running apps and / or check your amount with Auto Memory Manager (if you use the "Aggressive" profile it can free up some memory for the system to use).
3) Perhaps this is the time to visit your technical assistance. Your main board can even be damaged (sadly it can happens, for example, if your mobile is exposed too much time to hot temperatures).

[Q] Problems on Xperia pro K16i or android system?

Hello,
i have this mobile for about half year, but have there some problems, that i still not able solve.
1) I see problems with lags and unwanted pausing at some games. But still not found why. And how. Because in some games i do not click on pause button, but game when i moving fingers on display randomly go to pause, or go to black screen or stop respond for while. It look as weak procesor, or it is problem of memory? This device have low memory, but i try kill every aplication that i can, but problem still persist. And i have also problem kill some aplications. I kill them and they start again. And not are because because must run.
I also try disable builded antivirus but too without changes.
In some cases mobile start wifi conection or data transfer, that i have set off.
I dont know how i can receive email when i have disabled wifi and data.
And two times mobile send premium sms that i unable control, and not figured in mesages, and not know that i send that kind of sms. I call operator to block all premium numbers to awoid this robbing.
2) android market is extremly chaotic and it look there is security problem - google play. Is posible found most easy way how to block some aplications to accest to sensitive operations? (acces to call, sms, and other services?)
Im thing there is too much many aplications that want baseless access to some services.
3) is possible mount on this phone Windows mobile 6.5? Because that system been most suited for me and in basic have most aplications that i need, and have also a loot prety good games. On android are there minimal.
Or some way to modify rom and kick and kill stupid aplications and system layouts.
Please can somebody good, frienldy help?
thanks.
Still any idea?

Constant crashing...?

Hi Everyone,
Basically, I got my Samsung Galaxy Player 4.0 in January, and when it comes to the features, I have been loving it. This is my first Android device.
However, I have been having problems lately. First, some basic information: it's an 8gb device, and I have a 32gb class 10 microSD card in it. I have a huge number of apps on it (over 200), however, I keep careful tabs on what is running in the background, reporting an app if it runs in the background even when not needed and that will reopen if killed, and if I don't really need it, deleting it after a week. I've only had to do that with a couple of apps so far. As I use this a lot as a PDA (I don't have a phone, this basically covers those bases), I have a couple of things that always run in the background, which I want there (textplus, Linphone, MailDroid, SwipePad). After getting rid of the services that I don't need, I'm still looking at over 100MB free RAM. I'm still on the stock ROM, and I'm using GO launcher Ex. I reboot daily.
My problem is that it crashes often - sometimes daily. Usually, it will go something like this: An application freezes, the whole system becomes unresponsive, and I either have to reboot it by holding down the power button for 8 (?) seconds, or something snags and it reboots by itself. Usually the first sign is that the haptic feedback for the home button comes about a second later after I press it - except then it is almost always too late. The power button will usually turn the screen on or off, but the lockscreen won't appear, I'll see the screen as it was before, frozen. Sometimes, it eventually reboots, while sometimes it doesn't, making me hold down the power button to reboot it, and sometimes, just as it will start "becoming unfrozen" (it goes to the home screen and it starts loading), it will reboot.
It seems to be that after an approximate time of active use, it will crash. Before that, apps can freeze, FC, and within a few seconds, I'll be back on the home screen or in another app, doing something else. After that, on the other hand, it seems to me that whenever an app freezes or has a problem, it basically takes down the whole system with it.
Something tells me that this isn't just normal (otherwise Android wouldn't have over 50% of smart phone market share ), because I haven't heard of problems like this before, and other people with Android I know don't seem to be having the same problems (if any, at all). I have been reading around, and saw some thread about another phone describing similar problems, and it turns out it was a motherboard problem, so the phone was returned for warranty, except I don't remember where that was, I'm just hoping it's something like that...
OK, now that you've read my long post (sorry, I thought it would be best to give more details than get asked about them), I really hope this isn't something normal, because outside of this problem, I'm really enjoying all the possibilities, capabilities and flexibilities of Android (I'm looking at you, iPod). It's really quite aggravating, today I lost my public transit itinerary on Google Maps (I feature I love), and thankfully, I remembered enough to make it through, but it is quite frustrating. Please tell me this is not Android being Android?
Go Launcher is not Officially supported on these devices and swallows the small amount of ram very quickly, I tried it for a day and got rid of it because of how badly it impacted performance.
edit: looks like since I tried it they added support for our players, still won't run it, its to much of a system hog.
I don't know, but I tried switching to the default launcher, and it already crashed earlier than usual. Any other ideas? I'll try some other launchers over the next few days.
Sounds like you are running out of system resources. You say you have a couple hundred apps installed and I bet some of those are becoming active and hogging precious ram and cpu resources in the background until the system crashes. I have a 2 year old Samsung Captivate and I only have minimal amount of apps because it will often big down and become unresponsive and crash. So before you head out to a repair shop, remove some of your many apps and see if that helps.
So, if I understand, even if an app runs in the background for a short period of time, it still consumes resources, even after it's stopped running?

If you have a titanium backup freeze apps that run in backround and see what happens ..when you open programs they will stay in memory so use some memory kill widget to clean memory from time to time.I have a stock rom witch is not very good with memory menagment so sometimes when memory is full it just stop and only help is restarting ..so i use app "quick system info" which give you memory ajd cpy usage displayed in status bar and when memory is close 2 full i just click on that and it kill all other aps except what a use in that moment.
Sent from my GT-I9000 using XDA
So, basically, the ROM is to blame? As to Titanium backup, I think that needs root, and I'm not quite ready to root yet (I've done enough hacking on my iPod). I do plan on upgrading to android 4.0 eventually (once all the issues get fixed, this is my main device, after all), and I think I'm going to have to root it at that point, but I'll be able to test it on a different ROM then, as well as try freezing apps. For now, I've tried LauncherPro, which seems a lot more lightweight, and it seems to be making it through the day until I reboot, and seems to be very stable... it also loads my widgets lightnight fast, which is great.
Correct me if I'm wrong, but the way I understand it is:
obviously there are memory leaks, every OS has that
Android will not kill services, but only programs
If there are places where memory can be freed, Android will do that when necessary
If no memory can be freed, and there is barely any memory left, than a minor FC or a frozen app is all it will need to push Android off the cliff
Is this the way it works? And, then, when I upgrade to 4.0 (CM9), most of those problems should be gone (because of better memory management)?

[Q] How to find which apps cause memory leaks?

Could anyone show me a user friendly android app which can effectively show which apps cause memory leaks on a phone?
I can only find developer tools to detect memory leaks within apps like Eclipse MAT. Sadly I'm not a developer so I would rather prefer just a list of apps to uninstall and not the exact cause of memory leak within a specific app.
Thx for any help!

Why do you believe you've got some apps leaking memory?

Cause it doesn't matter which rom do I use on my phone (I've tried plenty of them) it gets laggy after a couple of days.

Check how much each app consumes from settings->apps->running, and compare memory usage from time to time. You can also use logcat and see what ActivityManager is up to, i.e. if it begins to kill apps more frequently ("No longer want ...").
But low on memory, is only one explanation of lag. An app usually don't survive long enough for a memory consumption/leak to become an issue.
OK. So what I actually noticed last time is the next: after a few days background apps started keep restarting. I guess it was because minfree tried to make some space to meet the aimed value, but system kept restarting apps cause they were essential. Since I started using greenify I meet this problem after a little bit more time as before, because I only leave the most important background processes unhibernated. That was the reason Isuspected memory leak.

I'd guess you've hit the limit of the number of simultaneous tasks Android can run before starting to kill them. If you get more than 15 running, ActivityManager have no other choice than kill the last recently used. And if they all are "sticky", Android must as well restart them, causing an endless kill/restart loop, only limited by the restart pause enforced by ActivityManager. Try removing/disabling some bloat-ware.
But you'll see this clearly in the logs looking the at ActivityManagers output.

I can assure you I don't have any (or at least not that much) bloatware on my phone. When those infinite restarts happened I had about 5 background processes. And those restarts started to happen after more than 2 days every time. If I had too much apps it would started without any delay.

Apps keep closing on galaxy S3

Hello, I have a really frustrating problem with my galaxy S3.
All apps are closing when I am using them.
It started with Google Chrome that was closing after browsing the web for a few minutes but more and more apps keep closing.
I installed many different web browsers but they all do the same, they freeze and close.
Games and other demanding apps are also doing this, for example: Real Racing 3.
I am running Android 5.1.1 Cyanogenmod and I already tried multiple roms that all had this problem. (All clean installs and I did a factory reset before and after the flashing)
I was thinking of a ram issue (the s3 only got 1gb) I checked the ram usage and there is always about 200mb free ram.
Using Greenify didn't make the apps crash less but it did give me a battery boost.
I don't know anything about the kernel ram settings and I don't know if this can solve the issue.
Is there someone with the same problem or does someone know how to solve this?
Thank you in advance.
edit: i also tried freezing all user apps that are active in the background
I found a sort of solution to my problem, I downloaded the app: Lspeed and I did set the ram preset on "game mode".
Background apps close so I won't get any notifications but I can play games or use heavy apps.
It is not the best solution but I will have to deal with it due to the 1gb ram.
