Multitasking the Android Way

My apologies if this is a repost but I came across this yesterday and thought people here might be interested. Anyone that has ever been confused by the way Android multitasks (let's be honest, we all have) should read this.

Interesting. And the author certainly has a cool last name.

Definitely a good read. Thanks.

I'm still TOTALLY confused between what a process vs service is and how everything works together. what's the difference between an app I just sent to the background vs its associated service or process? are they one and the same?

A process is any task that the CPU has to perform. For example, say you open a text file. That's a process. Once the file is opened, the process is done.
A service is a long-running task, often launched by a process. More specifically, services are A) for tasks need to run in the background, B) usually for long-periods of time (or indefinitely), and C) most importantly, independent of user-input. Instead, services usually respond to changes in the system (ie Battery Indicator, see below), or periodically checking the internet for something.
- For example, the Battery Indicator app, which puts the battery percentage in the status bar (see picture below). Whenever the battery changes in the system, the Battery Indicator service is alerted, and the percentage in the status bar is changed.
- Another example is the Google Talk service, which is running whether or not you launched the app. That's because it needs to stay open in case someone messages you.
Without services, nothing could run in the background for long periods of time. For example, without the Google Talk service, if you wanted to receive a message, you'd have to have the app open and in the foreground 24/7. Once you opened another app, you'd go offline. (coughiPhonecoughcough )
You can view your services in Settings -> Applications (on Sense UI anyway).

Very informative, thanks for that.

Excellent blog post! Thanks!

This would definitely seem to support the "No task killer" philosophy.

Good stuff to see...thanks

I wish I could agree with that but without some type of task manager, my N1 does not run smooth at all. =\

Low memory issue

I have just flashed an EnergyROM having the GTX Sense theme. After flashing, I checked out the task manager, and this is what I saw:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
This is what it says when tapping on the 85% icon:
Why is the program memory so low? I have tried searching for other posts regarding this problem, but I couldn't find anything similar.
I would also like to mention the fact that lately, my device has been acting very weird. I leave my place with my HD2 being alright, and after walking for 10-15 minutes, I get it out of my pocket only to see that it is completely shut down (or at least it doesn't respond to any commands). The power/end key does nothing, and the only solution is to reset it via the dedicated button on its back. I have realized that the phone is actually on, but the memory usage is so high that it simply cannot answer to any commands.
PS: Right now it says 88%.

you should install cleanram as it helps free some ram...also get cleartemp as it'll show you what's eating your space up so you can delete them easily...and finally don't forget to soft reset
one more very important thing which saves a LOT of space if you're on stock rom or your cooked rom doesnt have it(highly unlikely) is moving the album cache...read the thread here and look out for 4tune's cab
Edit: i just noticed your total program memory is at 197.91mb but mine is at 336.37mb...thats something to look at as well i think?

hi try try this program this is the trial if works pay for it
is all in one software

You definitely need to check into the amount of total program memory. It should be as damnshah stated - well over 300MB for a 512LEO device.
Perhaps trying re-flashing and see if the amount of program memory is still <200MB.

Have you solved?

I had to flash another ROM, so I decided to go for the GTX themed ChuckyROM. It looks better, feels better, and the memory status says:
Total: 453.6 MB
In use: 184.2 MB
Free: 269.4 MB
Anyhow, the phone is working flawlessly now! Thank you all for your support!

GingerDX battery drain related thing..??

Hello guys,
I found something strange in GingerDX ROM that I have marked in screenshot
Even this process can't be stopped more than 5mins. It starts itself.
In other CM7 ROMS there is no such process that is running in background.
AS written in second screenshot "kept for better speed", may be this is the process that also provide speed to system but also drain battery.
What do you think about it..??? Did anyone also found this..???

Hit the THANKS button if I helped you!

android core apps is a cached process. so it rests in the green half of the RAM indicator line. closing it wud result in less RAM

GingerDX v022 on Stock Kernel... NO SUCH PROCESS
"Running" shows ...
Maps, Settings, Maps, Android Weather, 3G Watchdog, DSPManager, Google Services, Android-Keyboard.
It's also not listed in the "All" tab, and I even can't find it with Titanium Backup.
Better investigate which app/mod spilled it into your ROM.

Tip for JB stock ROM users.

I am far from being an Android power user. I don't use mods, skins or launchers and prefer to stick to stock ROMs.
The farthest I go is to root my device, given the fact that some apps I need either work better with it or won't work at all without it.
So you have an idea, just the other day I posted I couldn't figure what "Greenify" was good for since, as I understood it, If we have to enter the app to hibernate/de-hibernate the target apps we might as well just launch and kill them, as needed, only to be kindly enlightened by another user about the fact of life that some apps do still run in the background, even after we've killed them.
...Pretty "tech challanged", right?
...but, coming from this "restricted" background, I do have a tip to share with you guys after having tried some online suggestions to deal with the relative "sluggishseness" and low Quadrant benchmarks I was faced with, after having migrated to JB XSP.
Apps took up to 3 seconds to launch and I was having this kind of values in Quadrant:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I tried a bunch of stuff to improve things up. I removed a series of apps I rarely used, even some system ones, using SystemApp Remover and inhibited others like MacroDroid. Still, no improvements.
Until...
Today, acting on tip read online, I went to "Settings" ---> "Developer Options" ---> (Activate) ---> "Drawing" and changed "Window animation Scale", "Transition Animation Scale" and "Animation Duration Scale" from the default values to 0.5x.
I got definite improvement in launch response, general "sluggishseness" with Quadrant values jumping to this:
Happy Puppy now
Hope this helps!
XK

I tried your suggestion and here are my results
Before change
4488
After change
3446
Restored to original settings
4146
Sorry for lack of images but I am unable to attach them.
In my case those settings did not improved the performance it actually decreased it. This might be on a case by case scenario but a good tip nonetheless

Note the huge jump in the I/O score. Seems out of character with the other devices.

Marshmallow have memory leak just like 5.0

Marshmallow have memory leak just like 5.0, that was fixed in 5.1 most likely the story will return once again and it will be fixed with 6.1
Hopefully also M7 will get 6.1 .
I there for just want to recommend to restart your phone atleast One time per day, since your device will become slower and slower it is on because of the memory leak. and it is not just huawei it is the same on all marshmallow phones, it is a google problem right now.

Do you have some details?

Unused RAM is wasted RAM. LMK on MM on our device is catastrophic. I have random closing apps like FB, FB Msg, Viber in middle of writing messages... And I'm not the only one...
Cached processes screen. You see here should be all apps that you exited via home button and it should it load quickly just like you bring minimized app on pc - it should be instant and it shouldn't reload it like our device is doing.
Free ram should be around 50-60 MB max all other ram should be used for cacheing background processes. Huawei software department need some help with understanding how RAM should be used.
See?

Reminds me of one plus 3 that released a phone with 6 gb but only use 4 gb of it. It is indeed. Memory is there to be used.
Anyway. I also have random close downs of apps especially kik but also other apps I think it is the memory leak on 6.0 that I'd to blame but this is a Google problem not a Huawei.

Still, no news regarding this >> https://code.google.com/p/android/issues/detail?id=195104
(Anyone noticed otherwise with the August security update?)
I m on 4.4.4 (S5), thinking whether or not to upgrade to 6.0.1. Probably worths it, right?
Isn't there a practical workaround for this issue? Like certain apps (e.g. Clean Master), that clean memory/cache a good alternative? Does garbagge still accumulate on the system after long usage?
