Database Develop

2.2 OS changes with cached apps and multitasking?

Anyone who uses system panel knows its the best task manager and the ONLY one that shows the device true multitasking. It's shows 3 categories, active running apps, cached inactive apps, and system processes. All 3 of this group shows up in 2.1. But in 2.2 froyo there is no longer cached apps group. It skips from active apps to system processes.
I asked the developer and he responded with the following:
http://androidforums.com/android-ap...eople-who-hate-task-killers-2.html#post882019
To Roger: sorry for delay in getting back to you as well, as far as I can tell the N1 with Froyo does not have any inactive/cached apps. I'm running the leaked Froyo version as well. On the other test phones (an Incredible, a Droid, and a G1) as well as in (non-Froyo) emulators I do see inactive processes as before.

Does anyone know what this means exactly? Has android 2.2 been changed where in no longer pre-loads apps? My observations on froyo using system panel shows that my running app list is now much larger than eclare with no cached apps at all, ever. Has Google changed this and removed cached apps? Or perhaps view are just now hiding it somehow so task managers cannot see this info?
If true then system panel would need an update. But that response from the developer seemed to not indicate that.

bump. so not ONE person noticed that froyo doesnt cache apps anymore?

this may only be an issue with the pre-released Froyo.

perhaps, but that seems like a pretty significant change to the OS. i'm wondering if they either changed the way the OS works completely, or if its just a bug that is being fixed for the final release of 2.2.

The 2.2 leak has a lot of missing code in it.
alot.

I don't have an N1 so can't answer your question, but I did notice that the developer you spoke to, TESTED FROYO ON A G1!!!

Seems logical to me to keep out until ready for final release testing, because you can test a lot faster if things aren't being swapped out and in.

He's probably not a developer working on Android, probably just a application dev. Why would he be running a leaked version if he worked at Google.. Also, I think maybe he just doesn't know how to properly form a legible sentence since it would seem he meant other phones he has, not specifically that they are running 2.2, though I could see how you might think that reading what he said.
I would just hold off on questions like this until a final release is out, it's pretty pointless to worry about until Google drops an official OTA update.

Ok so now that the official froyo is released, and the multitasking STILL works differently, where do we find out what and how things have changed? Cached apps no longer exist, instead all apps show as running in system panel. I'm surprised there's not more mention of this since it seems a fundamental change in OS has occurred. Anyone have any insight?

On the technical side I can't speak, but for the end user experience, Froyo's multitasking has been the same or better than before. I experience less "jittery" lag and it seems like more programs are not unloaded (ie: run immediately, no load time at all) vs before if you used say Facebook, then browser, K9 mail, few other things, then back to Facebook it was ~1s to reload.. Maybe Facebook is a bad example here, as it seems to ALWAYS load fast, but you get the gist..
It of course could be the extra ram available now... 512M total vs the 256M before?

Well, if they did significantly change something, it was really for the better. Things just fly now switching back and forth.
Of course, I was only stock before and only had access to half the memory. So it could just be keeping a lot more of my apps in memory now that it has access to the full 512mb.

Well using system panel shows that in froyo there is an entire group of missing app now, inactive cached apps, are just flat out gone in froyo. It doesn't seem to be related to the new available RAM in 2.2.

I noticed this on first day on 2.2
I think the possible reason is 2.2 support more than 256M RAM. So the 16MB free RAM threshold is hard to reach now.That's way we didn't see Inactive process. maybe we can try run alot of apps backgroud untill reach 16MB free RAM threshold. Then use systemplane to check if there is any inactive process.

I've already tried that, gone down to 14 mb but they do not appear. They are completely gone from the OS, and system panel developer already confirmed that they are gone from 2.2 and It's just the way the OS is now. Check the link I posted earlier in the thread. What we need to find out is WHAT and WHY Google made these changes. Why isn't anything mentioned in the changelog etc?

Are you just interested in knowing why? Or is it affecting you in a bad way? Whatever reason they have, it has improved performance a lot. I just assume they are categorizing them differently now. Because the apps 'running' in the background still aren't really running, they are just waiting in memory in case you need them again.

I'm just wondering why, and what exactly the changed. My phone runs great with no issues.
Previously system panel showed 3 groups of apps, the first was running apps, and these are the ones actually using some type of resources typically. While the second group was inactive, "frozen" not using any resources.
But now in 2.2 everything goes into the first group. And the OS no longer starts a bunch of apps pre loaded upon boot up. It only loads apps you use now. So still I'm wondering if now these 2 groups are combined into the one active list, can we tell the difference? Or is there no difference anymore, and only running apps are now shown?

Ok, so the frozen category would be ones that were FCed to release their memory. Which could kind of imply that the OS would remember their state.
Android doesn't remember the state for you if it is no longer in memory. It is up to the app to save its state when it is told it is going into the inactive state.
So it could be that the frozen category wasn't actually anything special, just apps that were forced out of memory, and now they don't even mention them anymore.
You said that you couldn't force anything out of the list though, right? If you can't get anything automatically removed form the list, I would say they just combined the two categories.

Another thing that changed is that its not possible to kill most apps. Browser and some others can be killed. But for. If most part if you kill something it just stays there running, or immediately pops back up.
But yes the frozen apps list is just plain gone. It was a useless list anyway. But I wonder what exactly they changed and what it means and how it works.

[Q] Full RAM after using a some apps... with a little analysis

After fixing some lags with I/O system by using filesystem LagFix I still have a Lag problem in my system and I think it's not related to Samsung.
I think this could be an Android problem.
After a fresh reboot I get 124MB of free RAM.
BUT... every day I need to reboot the phone because after 3 hours it became laggy.
Now I analysed this and read a bit about the memory management on several forums and was able to reproduce the lag 2minutes after reboot.
I just need to use much applications one after another to raise the RAM usage for every application.
When the free RAM reaches 40MB I think the system clears some pieces for using it for the app I now want to use and there is the LAG.
Is there any fix for Android not caching every activity of an application in the RAM?
Now for me Android feels like: Usage -> Full RAM -> Lag
Sorry for the new thread but after 2 hours of research I didn't find anything useful over search function.

Yea, every program should have as much ram available as their size. 2gig for program storage on sgs, so there should be the same amount of ram ;D Anyway, theres still less memory for programs on the sgs than for example in the N1. I'd say there is about 384MB of ram total on the sgs and not the 512 claimed.

Not just the RAM for the apps... there's much more...all mails from internet, all google talk conversations, the wather I checked out from internet with any widget, feels like every interaction is cached into the RAM until it reaches the 40mb mark and after that every interaction on my system is laggy... for example: opening the notification bar needs 2-3 seconds.
I already talked to N1 users with the same problem

Heading out the door in a minute so can't comment on the rest, but I strongly disagree with that part of your statement.
As an N1 owner I've NEVER seen lag like I suffer on the SGS. Never seen the absolute FREEZE in the GUI like the SGS gets.
I'm running FroYo on the N1 now, so can't compare side-by-side to the SGS things like memory usage, but I don't think that's the issue here if you're going to use the N1 as a comparison, despite other users complaining of lag.
You might try Autokiller or the free memory manager app from the Market and see if that improves thing, they'll keep more or less memory free depending on settings. You could test how soon lag comes with default, minimal, and aggressive settings.

I never testet Froyo because everyone said, it's unstable but for me it seems like froyo has other RAM management than Eclair when you said you can't reproduce this problem.
I'm already using a task killer... I have my main apps ignored or excluded and most time there are 2 or 3 apps which will be killed after lock or time or what else.
What's the problem here... if I would use a PC with 512MB RAM and use only 10 small applications, it won't cache everything in the ram until it's full.

Hi, didn't read all the posts, but u should look into the RFS file system, which is samsung proprietery file system. It has a very bad implementation on android (i could be wrong). As for ram, the phone has 512 mb, but 128 are reserved for Gsm/data connection. Just think if you had an incoming call and all your ram was in use, u had to wait for the system to clear up some memory before being able to receive the call physiclly. That would be a long wait.
I could be wrong and sorry for the bad english.

Have you ever tried "Minfreemanager" app?
It can change the minimum available memory level in different app usage.
The device must be rooted first.
Then select "Aggressive" preset and see the result.

DAMN!!! Nice app... it does exactly what I need cleans my RAM so I'll get 120MB and after that loading of apps is much faster than starting apps with Android included RAM cleaning.
It just cleans my RAM like a reboot but without the reboot
This should be a temporary solution until someone finds a better solution or until froyo is released.
I would like to have an application like this with an autoclean option on 2 hours

Guys please,
Getting off-topic here. Here is Android Development.
Not Q&A or General.
Please post in the right section.
Here is getting too many off-topics that pose no relation to Android Development.

Auto killer is better.Its exactly the same as minfreemanager but can be made to apply at boot.Minfree manager resets itself at boot.

I use Memory Booster Lite (free version) app to free up memory, must do that manually but it works very well, if you buy the app it free up memory automaticly.

No, wrong. The reserved ram is in the form of a ram disk, which seems to be a bit oversized. Not really sure why a ram disk is needed at all, personally.

This is the correct solution. the JF* series of firmwares have very bad default settings for killing unused apps. Use this app to set them a bit better and you shouldn't have any problems.

It does have 512 of ram, but some is partitioned off for the phone, so that you can always receive phone calls. Just about every device does this, because users would be more upset if they couldn't pick up the phone until they had closed a bundle of running programs. Don't you think that people here would have noticed earlier if the SGS physically had less ram than claimed ?
As far as the OP is concerned, sounds like you are just running too many programs at once. Its not an android problem, its user error.
Any task manager, but particularly an auto-killer will set you right, although alternatively you could try not leaving every app open when you're finished with it. You think your PC would run ok if you left one game open while you opened another ?

I wasn't comparing a N1 on FroYo to the SGS on Eclair. My comments were in regard to when I was on Eclair, which was several months...FroYo's only been available for a couple of months. What I said was since I'm on FroYo now, I can't compare side-by-side, but my experience with an N1 on Eclair was never any lag problem or GUI freezes.
Anyways, I also suggested you try Autokiller, and you missed that or misunderstood it by saying you already run a Task Killer (which is generally considered a bad idea, but I see you picked up on Autokiller after someone else suggested it. Enjoy.

Thank you. This removes almost all lag I'm experiencing.

[Q] Why does many installed apps increase lag?

Can't see why this is the case (but it obviously is) as long as I have lots of free disk space and not many apps running at the same time. Any logic in this?

I've been experiencing the same issue and wondering the same thing...

There seems to be several things causing this, but the two key issues are:
The moviNAND (the internal flash drive/"SSD") firmware seems to have an issue with fsync() taking extremely long. E.g., it slows down whenever a file is written/updated on the internal storage.
RFS, the file system used by Samsung is buggy as hell and corrupts data after a while.
There are several topics on these issues in the Android Development forum. There are also several "lag fixes" trying their best to overcome these issues. Go check them out

We have no idea if that is ACTUALLY true.. Just because fsck picked some things up on 1 phone, doesn't mean it happens everywhere.. Furthermore, it doesn't mean the problems detected affect operations

that has no truth at all about more apps slowing down the phone, my phone is the prove

Before jpk i didn't noticed slowdowns with aprox 100 apps, now i do on jpk =/

With autokiller the phone is still laggy.
And please, stop thinking I'm stupid or I don't know a **** about smartphones, ROM's changing, firmware or knowing how a phone must run.

AFAIK this topic and its responses are for the OP

I have about 190 Apps installed and do not experience any diferene in overall speed of the phone. But only because i know that a lot of the programms start on boot and stay in background.
I have more than 15 apps turned off with the full version of autorun killer to prevent the auto restart of the apps. Otherwise the phone would definetaly slow down.
It´s really incredible what apps start on the boot!

Do you need to be rooted ti use all of the functions in autorun killer? I am not rooted.
Can you compile a breif list of the "biggest culprits" to stop with this utility to gain back the most speed and efficiency? I am a bit nervous that I will stop the wrong items and somehow damage my phone...

Autokiller and task killers are not the solution here! Quick lesson on Android, and why having even A SINGLE BAD APP is going to ruin your whole phone!
Android has something called an 'Intent'. In order to start an app, an intent is made by your launcher or a button you press, and the Android system reads this intent and works out what app it needs to start up.
There is a second type of intent though, called a 'Broadcast Intent'. This is an intent that is sent out to anything that is registered to listen to it. This means that an app can register to listen to all sorts of events, such as battery level changed, application start, or a tons of other things. Even if the application is closed, if it is registered as a listener, Android will start it right back up so it can deal with the intent. If the intent comes every 5 seconds, Android will run this app every 5 seconds even if you have a taskkiller killing the app.
The only real solution is to not install apps which are bad! Finding bad apps is a real mission, too. Hopefully in the future, utilities will be available to let us track down these terrible apps, but till then, you'll have to work it out yourself.

No need for Root to use all features of Autorun Killer. I would disable only the apps you know and which you do not need at startup and running in background, such as (in my case) Paypal, App Center from Androidpit, Daily Briefing, Photoshop Express, Word Press, TweetCaster, etc.
Every of these apps works normal, even when deactivatet on startup.
So unless you do not disable system apps (must be previously set enabled in settings) you are safe.

There is an app called Autostarts at 0.95$.
It shows what is launched au startup, when you enable/disable wifi etc.
It think it gives insight on how apps seems launching out of nowhere.
I also reccomend Watchdog Task Manager Lite, the free version.
It does not kill anything, but notifies and logs the bad apps that consumes over a certain CPU percentage.

[Q] memory usage

Good day!
Im new to xda-developers forum, just found a link in youtube while watching some stuff about galaxy note.
I have not discovered my galaxy note thoroughly yet coz its still new to me. Just wondering, the usage of memory without running any apps will go about 60%-70% percent. My temporary solution for this is to run task application and kill all exciting apps. Just wanna ask what kind of problem this may be?

No need to get alarmed by that. That's the way Android runs: it keeps apps in cache, so you can access them faster. When there's too much of them cached, the system kills off some apps.

in this case, i cannot access on other apps that i'll run. just manually kill all the apps every-now-and-then.

the only thing is, when i access on other apps like games. loading on the apps takes longer or even it crashes. maybe its because of the memory allocation of the apps or just there is no enough memory space to allocate the app.

While what the other member said is true, unused memory is wasted memory, but the issue is exactly that. Android ends apps that you may be running to be able to open more apps, which I find bad.
While it is normal to find the amount of ram you have said already loaded and being used, I still don't like it.
There are times that I'm trying to multitask and I open an app and right away jump back into the previous app to find that Android OS has decided to close it, within 3 seconds of hitting the home button. It makes multitasking a little harder. But there are ways around this .
But still, I hope ICS fixes this issue. I don't need 200 of the 1 gig of ram in use, what I would like is to have 300 or so free to be able to multitask normally.

RAM always at 70% on MI5

Hello fellow MI5 users,
I received my phone one week ago and I start having some issues with the RAM. In fact, at the start of the phone, it's already at 70% filled up which is too much for me. Indeed I use a lot of RAM and I'm that type of guy who let the apps running in background everytime because I keep opening them everytime. I was wondering if it was possible to have a link to a better ROM because I guess it's the problem and also a link for a tutorial on how to flash it I'm a newbie in this type of manipulation but I'm very interested so I hope you will help me guys. By the way, my MIUI version is the MIUI 8 Global 6.8.18. I honestly don't know what can i give as information but I'll answer ASAP at any questions
Have a good day

This is working as design - Android keeps apps in RAM to reduce I/O on resuming from background - faster & more energy efficient.
You can change the number of background processes via the development settings or you can kill apps on closing.

I've seen that indeed but it was set at standard so I'll probably put it at 3 I guess. How should I set the memory optimization? I've read it should be set off, altough I tried middle and I feel comfortable like that?
Is it normal to start at 70% without anything started ?

For the 3GB version? Pretty much. MIUI is horrible.
After booting I typically had 1.3GB / 3.0GB free but after a while this averaged to around 650MB free.

I know that but I need more because I use multi-task a lot. Is there a way to change the ROM so I have more space to work with? Even if the ROM itself is beautiful.
Indeed it's the 3gb version 32gb. It have lags sometimes and I think it's due to the full RAM. Can I have a link to a custom ROM which works fine on this device?

I'm a little confused, you want as much RAM available but you want as many processes in the background as well? That sounds contradicting to me. Memory optimization maps to ZRAM, if you set it off there will be no memory compression and thus even less processes will be kept in the background. If you set it high, you can have as many processes as possible, but there could be lag due to (de)compression time overhead.

Try different Rom
Try to use a different Rom. On the Stock Rom is a lot of bloatware which is using your RAM too.
First you need to get an Bootloader unlock permission and have to unlock the BL.
It could take up to 10 Days to get the permission from Xiaomi

After that you have to flash a recovery like trwp via ADB. Google it for videos or threads how to do it.

After that you can flash a developer Rom.
I use the Resurrection Remix and it works fine. The CM 13 stucks in Bootloop. Maybe because I made a full wipe and had to sideload my rom.
Because you don't have a SD card option you have to have the room installed on your hard drive. But just follow the description below
http://forum.xda-developers.com/mi-5/development/unofficial-resurrection-remix-m-5-6-9-t3395945
It took me just 1 day to get the unlock permit but don't try do do it without it. You brick your phone.
The RR Rom works really fine. Fingerprint and everything. It has no bloatware and you have to get the gaps like in the description. Arm64 nano seems enough.
Good luck and fun with a great phone.
Normally the android system kills the unused apps even in background. But i also experienced lack in multitasking.

I think you misunderstood the OP question, he wanted more free RAM at start in order to have as many as possible apps in the background.

Yup exactly

Try trwp 3.0.2.0 with 3.0.2.1 people experience bootloop

In fact, I'm just doing some research before asking because I'm very new. I have found some videos but they are pretty old and not on this phone but I guess it works more or less the same way

OK, in that case, just open Security->Permissions->Autostart and disable those which aren't immediately needed upon start. I have 18 autostart items (mostly system monitoring & social media apps) and I usually start with 1.5 GB free RAM.
