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.

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
http://forum.xda-developers.com/mi-5/how-to/unlocking-xiaomi-mi-5-bootloader-t3336243
After that you have to flash a recovery like trwp via ADB. Google it for videos or threads how to do it.
http://forum.xda-developers.com/mi-5/development/recovery-twrp-xiaomi-mi-5-t3412123
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.

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.

[PROPOSAL/REQUEST] Can we have a Go Edition ROM for Huashan?

Good Day.
I would like to clarify that I do not know how to create ROMs and I do not know how to write codes(anymore) but since our devices are aging, would be it great to send our Xperia SP off with a bang with an Android GO edition-like ROM? our devices cant handle newer apps and processes anymore but at least I think the Go edition ROM can still make our phones as usable as daily drivers either on Android Q or Pie.
please consider. thank you.

As far as i may concerned, LOW RAM optimisations are already implemented in the codebase for current active ROMs for Huashan. And, to the best of my knowledge, which i may be wrong, these optimisations are derived from Android GO itself. I vaguely remember that at one time this is a main topic said by Adrian the master himself.
Huashan is no longer capable to run modern apps that somewhat uses heavy resources (which i myself don't understand why Instagram needed such a computing power). Unfortunately neither do current Go phones. That is why PWA is a thing to all Go devices. I.e. Maps Go, Twitter Lite, etc.
Of course this is not an objection to your proposal. Just thinking of dropping my thoughts here

Android Oreo and Pie just doesn't cut it well for this phone.
Instead of shoving newer android versions down this phones throat expecting miracles. We should go back to one of Lollipop or marshmallow ROMs and realise how much lag free and usable it is. They're still pretty modern looking and does the job well.

Free yourself from Google and then you'll see how smooth current ROMs are.
Not to mention that they offer battery times like 7-12 days.

I don't use gapps on LOS 15.1. Knowing that they crap the phone out.
LOS 15.1 is good, we get latest security updates, better UI etc.. but hangs and stutters more with apps and multitasking.

I don't agree with that, KaBombaBoom. I ran Oreo for a long time and recently upgraded to Pie. The phone is still surprisingly fast until some hungry app gobbles up all RAM and it starts running on swap.
That's what doesn't cut well for any phone in the long run, those apps that keep growing bigger and bigger and requiring more RAM though mostly or no new functionality is added.
Google Play Services itself is heavy, not to mention other google apps such as their mail, I open it from the browser these days. I'd love to get away without GApps but retaining the deep sleep wake that push notifications provide.

That's the main reason I never tried android without GApps. That and the fact that all drivers are mostly proprietary anyways, so why bother

Of course it wakes up. I've been using it as my daily driver with WhatsApp for some time last year, and it was perfect. There was just one problem which I could not resolve : message backups. I mean, it was working perfectly when I made backups on the SD card, but if I wanted to have them somewhere in the cloud, the only option was the Google Drive - which is not working without Google services.
Btw. it's possible to use One Drive instead of Google Drive (eg. for photos backup in the cloud, but not WhatsApp - if you have maybe Office 365 subscription.
And it's possible to have anything else running without Google - contacts, messaging, even a lot of applications indicating they need Google on the phone - they are working without Google anyway. Thet's except for paid apps, of course.

best rom for mi9

Hello,
Bought my mi9 3 months ago, but don't apreciate miui at all.
I don't like google and all the apps i don't need.
I hope i could find a rom from xdadev but i'm lost, too hard for me.....:crying:
Perhaps somebody could help and drive me to the good place ?
Best regards.

Lineage OS is a good value if you don't want google apps. AOSP apps replaces it (browser, messaging app, phone, camera, ...), but there is no bloatware.
But if you want to have more customization features, you can test crdroid or havoc os for example.

If the only reason you don't like miui is the amount of useless apps, all you need to do is debloat all of them. Even the Google app can be debloated.

I'm having trouble with all of these interface changes; I'm getting old.
I don't know if it's simple to unbloat my phone or change completely the rom, or if I risk bricking it.
Could you tell me if it is possible to save my stock rom or find it somewhere, to come back to it if i give a try to lineage os or debloat my useless apps. I have global 11.0.6.0 QFAEUXM.
Is there somewhere in the mi9 forum a tuto for newbies to change the rom to lineageOS ?
Installed ADB/Fastboot tools, but don't know what i can uninstall without problems ; i don't even know what are all those apps.
Sorry for my bad english.
Best regards.

Hi @chaussettdeguerr, I suggest you use the original one from MIUI. Based on the information above, you will have 11.0.8 soon. You just need to organize the icon into an Unused folder and forget about it (troubled applications). Anything else you can do as you like from themes to font and so on. From my experience, changing from one room to another is not a good idea for long time user. It will waste a lot of time from here to there. You can alway try new themes and stuff from the Store until you like something without switching rooms

Thanks
But i installed ADB tools as suggested and removed 31 apps.

Thank you all

I thing you have to select from 2 categories,
MIUI based or AOSP based
If you care about Camera and stability, go for MIUI based.
If you care about Smoothness, Stock android 10 gesture and light battery usage.
I couldn't stay more than 3 weeks with AOSP because of serious Camera issues, 4K Video recording was choppy, photos shotted at 2 mega pixel if I set to 16MP or 48MP.
Screen Mirroring will not work on AOSPs and will reboot phone.
My recommendation is Xiaomi.EU or MiRoom (first boot is in russian language and you have to search in settings to find Eng language )

Question is there any way to overcome Miui controling over apps and permissions

Hello guys
I am on MIUI 12.0.5 and I am suffering from miui constantly shutting down my apps permissions and making the apps services stop for example accessibility or usage permissions. I am tired and tried all solutions available from locking the apps in background to removing miui battery optimization, still miui finds way to stop the apps.
does rooting help in this regard because I am really sick and start to look for another phone brand.
Thanks

You have to install a custom ROM.

This is one of the reasons why some reject Miui and choose for a custom rom.

guys I actually tried almost all custom roms for this device with no offense to any rom developer nobody could make a stable rom [without deep sleep issues which ****ed me] like miui sadly that's why I went back to miui 12 in hope that It's less aggressive than 13 which was crazy controlling
I want other solutions than custom roms because I don't want to format my device now and I never found any rom that suits all my need, it's either have nice features but not stable or the other way.
