[Q] CM9 : Permanent Background process limit

Hi guys,
just one question, search for it but didnt found a solution jet.
I´m using CM9 , latest version ofc. Under Settings -> Developer options -> Background process limit there is some options to choose. I´m unsig "At most, 2 processes". But, after rebooting the device, the option reset itself to "standart".
My question is : Is it possible to set this command as an startup file in the init folder, that after every restart it will be "2 processes" instead of "standart" ??
I hope to get some help, thanks !!!

Just a thought but I doubt you can as the phone needs more than 2 process to boot up?.....so I'm guessing this won't ever be a persistent or init.d feature,

I´ve the same problem....
But I´ve an idea. This app runs an sh file on startup: search in google play for Autostart (root).
but I don´t know the command to set the background process limit... And I don´t know if theres any...

Or can somone say where th Backround Process Limit is saved?

Pretty interesting feature that saves lots of memory and makes the devices work better; i have been using this feature on my Samsung Galaxy tab 2 7, and still setting it up. Makes thing runs better although sometimes you can kill apps that you want to be running in the background.
Any ideas on his question?.

I'm setting up phones for other people and I have found out that it is the single feature that probably speeds up -the most- most of the phones especially those that are low in the memory department.... Unfortunately to most of the people (that I'm helping with their phones) it is impossible to set this option each and every time that their phones boot so I thought maybe I'd add it a as init.d feature or -maybe so that not to disrupt the booting process- as sth which would run after a timer (which -say- lasts for a minute) runs it's course.
My only question is if anyone know how to enable this feature programmatically (e.g via shell)...
(sorry for the thread ressurection btw)

Two years old unsolved thread and no answer yet... what a shame ...
Greetingz.

this app works for me, there's an option in settings to stop background processes http://forum.xda-developers.com/xposed/modules/recent-app-cleaner-t2734053 although you need to be rooted and have Xposed Framework.

Finally figured this out, man was it annoying.
I need it for my 2012 Nexus 7 running Android 5.1.1
It was running slower than molasseses until I changed the data partition to f2fs (make sure you have a kernel and ramdisk that support f2fs!) and enabled this tweak.
It can be done with root access with a single command.
service call activity 51 i32 x
Where x is the number of background processes you want.
If the API changes in the future, it's easy to look it up again.
http://grepcode.com/file/repository...4.4_r1/android/app/IActivityManager.java?av=f
Look for the line with SET_PROCESS_LIMIT_TRANSACTION
Then just extrapolate that info to http://grepcode.com/file/repository...ERSION/android/app/IActivityManager.java?av=f
Replacing DESIRED_ANDROID_VERSION with the version you're interested in.

Activity number has changed for android 8 and 9
For now the end of 2019, android 8,9 has been the major platform for recent user's handy phone, the command for those use:
```
service call activity 51 i32 x
```
can not be exactly do what you will see in android8 and android9, the major issue was for the activity number '51' must to set it to 42 to Oreo and 47 for Pie, see github issue link (https_:_ //_github.com/flode/SetAndroidProcessLimit/issues/5#issuecomment-546690235 )
That means you should use: `service call activity 42 i32 x` for Oreo and 47 replaced for Pie.
Hope for adding new activity number for Android10

[Q] Ram issues, often less than 256 MB free

The title is the real starting place of my issue. Out of the devices 2 GB, 1.5 GB is the average amount that is used and its really starting to impact the performance of the phone. The few things that I have tried never seem to be a more permanent solution. My Moto X is Rooted with a Sunshine Unlocked Bootloader.
Normally on my phone I have the following running in background:
tasker & Related plug ins
Xposed framework
Some widgets( Evernote, weather & Calendar)
Here is what I've tried so far:
Greenify, to help manage what apps are operating in the background.
Uninstalled a large number of my tasker plug ins
Reduced the number of Xposed plugins that I have running
Reduced the number of widgets that I have my launcher running
Here are my ideas that I have left but I don't know what it will fix.
Find an app launcher with lower RAM requirement that still meets my needs. Currently using an old version of GO Launcher I like.
Wipe the phone and start over with the stock AT&T 4.4.4 ROM.
Another possibly related issues is that I've been having apps crash often, like Touchless controls and Contacts, but when I try and send the bug report it has my own address listed instead of Motorolla's.

have you tried flashing a stock firmware through RSD LITE? have you tried doing a hard reset? from stock recovery? your problem sounds like that a 3rd party app has screwed up your phone... And please dont use 3rd party launchers... They cause alot of problems.

If you asking to me stick with stock launcher I don't think I can do that. There are a lot of features the stock launcher is missing like Folders that sync to folders within the App Draw, just the way they display an open folder, the ways you can organize the app folder, how you hide apps you don't use, ie keyboards and the visuals associated with the uninstall process. But if you have suggestions on how to resolve some of the feature differences I'd be interested to hear.

You should check the running apps in the settings also check the cached background processes.
You'll find the culprit there.
Post screenshot if possible.
It's probably Facebook or something like that

What would you say is a good threshold to use to consider if an app is a problem? Would you say more than 25MB? 50MB?

Apps like chrome consistently use 100mb..
Otherwise 50mb

Take that last hope..Rsd lite your stock firmware and all your problems will be vanished.. Im sure..
A hard reset is a reset which you do thorough the Bootloader of your phone without booting to actual android home screen... Like you open your Boot loader by pressing appropriate keys and select recovery and Erase Cache and Factory reset from there... Google Hard reset and learn about it. Its really important to learn about hard reset if you own an android device..
As far as your launcher is concerned i can understand... And i dont really think that the launcher might be causing the problem... You just need an RSD LITE flash to completely wipe your phone and bring it to the factory state and make it completely fresh... I bet rsd lite flash will fix your problem because it erases the whole device and reflashes everything like boot,modem,system,kernal etc... GO FOR RSD LITE FLASH... and please take extra precautions before Flashing through RSD LITE.. because its risky if you do it in the wrong way.... Make sure to find the exact firmware of your phone which matches the carrier.. and also check the bootloader version of the firmware.. DOWNGRADING THE FIRMWARE WILL BRICK YOUR DEVICE PERMANENTLY.. so always upgrade or flash the same firmware as you have now.. Take extra precautions.. Good luck..

It is Linux based, free RAM is wasted RAM. The system will put stuff into memory as needed, and remove it as needed. The system tries to keep as much stuff in memory as possible to improve performance so it doesn't have to put it back into memory if you launch it again. It is how the Android memory killer works, and the kernel is what controls the free memory.

if this is true why do i have more performance issue when the ram is full? I have to wait for the phone to respond to the touches on the screen.

If that is the case, then your device is likely not freeing memory properly. Either an app is not closing properly, or you have a lot of background apps running that can't be freed from memory, or you have a rogue app killing your phone.

As he said, "free memory" will always be very low.
This is part of why people freaked out over vista... As modern kernels do, it was using most available ram for tasks that might happen because this memory can be cleared instantly. But vista actually reported this memory usage, and people freaked out, not being used to the concept. I believe they adjusted how memory was reported in 7...
Give this a read
http://serverfault.com/questions/85470/meaning-of-the-buffers-cache-line-in-the-output-of-free
If you have a terminal emulator the command "top" will show you memory usage by category so you can see not only how much is free, but how much COULD be free at a moments notice if needed. This is what you want to know.
"atop" is another version of top, it reports slightly different statistics and can be a little more readable...(it may be htop not atop, if one doesnt work try the other. They both exist but only one is prepackaged and... I forget.)
You should also be able to look at processes to see what is using up significant amounts of memory....

How long does it take to set Apps to "Inactive"

Ive been running Android 6.0 now since a while on my Nexuses and all apps are still marked as active (Developer Options -> Inactive Apps). However im pretty sure i didnt use all of my apps in the recent time.

I Dont think anyone knows what this setting means. Including myself. I just noticed it and wondered what it does...

iirc it has to do with marshmallow's doze feature. and it just allows you to "doze" an app manually I think. I forget where I read this but I remember it one day reading random marshmallow articles on the internet

Hmmm does that eliminate the need for greenify?

Maze Alpha X shipped with adware?

Accidentally I stumbled upon the folder gangyun and pref_storekeytool inside.
I scanned the Maze with an antivirus scanner and beautysnap.apk was reported as adware.
I guess beautysnap.apk is part of the system camera?
Unfortunately no app can beautify me, so I would like to delete this app. Is it safe to do it?
TIA

What virus scanner did you use? I've just received my Maze Alpha X. There are some bad things about this phone, I'm a bit disappointed. The worst in my case is that the front camera doesn't work. It's like there's no camera at all.

Yeah unfortunately this phone is loaded with precarious apps, adupsfota for instance disguised as the ota wireless update is full of dodgy adware/spyware and if you look at the permissions your see just how worrying it is, it has permission to access banking apps, android pay, key-logger, microphone, camera the list goes on, I've disabled it several times but it manages to re-enable itself. Beautysnap is also a bad one which I have managed to disable for good, LocationEM2 is another suspect app, Fotaprovider which is also adups related. Basically this phone really needs an alternative kernel/custom rom before it can be safely used but as far as I'm aware there isn't one as yet.
The CPU usage is always very high too which is not a great sign, not good at all, I'm surprised Amazon can sell phones in this state tbh.

Ive used a few but the adware/malware/spyware that the phone has installed as standard on the kernal/rom it's shipped with are installed as system apps with the exception of beautysnap so you need to go through them manually. I used an app called SystemPanel2, it's a great app that gives you a really complete overview of whats running on your phone and what not, it can record system processes, memory, battery and cpu usage over a period of time as well as network stats.

I couldn't be able to find those suspicious apps. I've run a bunch of virus/malwares scanner, nothing reported. I've installed SystemPanel2 and I didn't find the processes you list. I believe our phones run different firmwares. I've got mine from Gear Best.

Under your Wireless Update system app what does it say? On mine for instance is says "com.adups.fota". If your firmware is good/clean then that's a good sign that if I put a fresh stock rom on here it should be fine, I was thinking maybe all the maze alpha firmware's were affected.

My com.adups.fota "seems" to be clean.
For hibernating apps on my rooted Alpha X I use SD Maid Pro.
Under app control you set several things
A) Hibernate the app
B) Disallow start on boot
C) Look up where all the files of the app are located
D) Remove app completely
E) etc

No such thing as clean addups I'm afraid dude.
A newly discovered malicious app is found on China-made mobile devices running the Android OS. This is a baked-in system app used to update the device’s firmware but is found to also steal personal information, among other things. A blog is recently published about this malware by Kryptowire.
Already we have had inquiries on whether we detect Adups or not. The answer to that is I believe we do. You see, the app in question, which goes by the package name of com.adups.fota, has a couple of variants. There is an older version seen around 2014 and a newer version that emerged mid-2016. This older version we detect and have done so since 2014. I can verify that this older version was indeed pre-installed on various Chinese mobile devices bought cheaply on online stores, mainly Amazon. I know this because ever since we started detecting this older version of com.adups.fota, we have received support tickets periodically about why we are detecting a system app that cannot be uninstall—I’ll get to how to address this later.

I want to know if theirs a firmware for the Maze Alpha and the Alpha X without addups baked in, I hope so because it's a great phone otherwise.

Defragmentation option appeared. Wow!

For the first time ever since getting my Mate 10 on launch day, I just received a pop up notification to defragment my phone which will improve performance. I did so. Wow they were not wrong there! Everything is so quick now. Apps launch super quickly! Anyone else had the opportunity to defragment their phone?

Mate 10 non Pro. ALP L29C636. UK.

Stange, I got the same phone and rom version .
All I've got was an update to .132 yesterday....
haven't noticed anything about defragmenting phone......
Where can I find it?
cheers.

Great Post.

I don't think you can find it. It just appears out of nowhere. I guess it depends on how much you have used your storage and delete and save files.
One thing I have done recently is empty the recycle bin folder in the gallery app which had over 30 days of deleted photos and videos. Perhaps deleting the accumulated storage taken up left a big gap in the storage file system. This is purely a hunch. Have no idea if this was the reason I got the defragmentation notification.
I wish I took a screenshot of it now.
Just found this blurb.... Defragmentation is mentioned....
"The HUAWEI Mate 10 and HUAWEI Mate 10 Pro take the “Born Fast, Stay Fast” promise to a new dimension. Leveraging AI-powered Battery Management, the devices improve memory allocation utilization, using different mechanisms such as: CPU Resource Allocation and Management, Run-time Memory Management, IO Resource Management, Storage Management and Defragmentation and Battery Management."

Yup I get a de-fragmentation pop up once in a while.
Still waiting for a firmware popup.

I saw this once and laughed, remembered me of Windows 98.
Android is supposed to support trim, so devrafmantation shouldn't be a thing... Unless Huawei is calling it Defrag but instead they're doing something else behind the scenes.
Anyways, the born fast stay fast BS is based on the system continuously trying to shutdown processes ASAP and keep them from working properly, and it's continuously pushing the user to delete all kind of "unused" files.
So I've a phone with 128 GB storage and 6GB of ram, but I neither can use the storage nor keep apps open in RAM cuz the system doesn't like it.
Wished we could disable the phone manager and its BS entirely.

I agree, that could be the reason apps like Adguard keep getting killed regardless of if its been whitelisted in Phone Manager.
As we approach having a stable TWRP/Root solution for ALP's, (cudos to Pretoriano80) I hope devs would find a solution to the over zealous AI/NPU.

You are full of BS, one of the weaknesses of F2FS is fragmentation decreases performance more than EXT4, so it actually needs defragmentation.

doesnt F2FS do auto trim?

I just got the notification to defragment on my Huawei P10 VTR-L09 and I clicked it, But I was doing something so I decided to go back to it and do it later. I figured I would be able to do a search In the settings to find the defragment option. Well guess what... It is not there. I guess the only way to defragment is when the system wants you to and not whenever you feel like it. I should have just done the defrag when I first got the message. Now I have to wait until it pops up again.... They should give you the option in the phone manager. Anyone know how frequently the defrag option pops up??

Yes a warning to others. If you get the defrag option, you MUST do it there and then. Do not navigate away from that notification as you can't get it back.
