Hi there folks.
I'm new to Android system, but I'm a lone wolf of Linux and Unix system administration.
I have some question about it's resource management.
As I have searched, Android manages the device memory as a pool where it lays the apps pre-loaded in a priority-fashion, layered from 1 to 6, closing what is no longer necessary and keeping recently used/most used apps loaded for fast paced use.
Is that correct?
Also, I want to know more about memory and processor management.
Speciffically if I can use the same concept of memory management in Linux and Unix systems in Android. I'm thinking about developing scripts for memory and processor optimizing (to save memory use and processor time for the sake of battery duration).
I searched but couldn't find any reliable documentation on it.
Could you enlight those for me?
Thanks in advance,
Rafael Umbelino

Hello!
Recently I'm doing research about OS optimization when using SSD and I was wondering if Android implements some of them, but I didn't found anything about it. Do you know for example if it saves less timestamps (or other metadata) than normal to reduce writes, or how it handles the fragmentation of data?
Thanks in advance for any help!
I'm developing for Android mainly with Qt/Necessitas.
It installs a runtime (similar to .net runtime, JRE runtime) to phone internal storage.
As the runtime is fairly large, few tens of Mb depending what is used, I'd like to filter out those devices with a small internal storage upfront.
I haven't been able to find a proper way to do it. Is it possible?
For now I'm trying to achieve it by insisting on armv7, large screen, thinking that more recent devices have bigger screens and a modern cpu, which usually correlates with more internal storage.
I would have posted directly to android developers, but I don't have the kudos to do it...
Hi guys i'm trying to simplify a project i am about to embark to make a proof-of-concept "Android spy watch" lol.
I havent found anything like this anywhere on the net however i feel that i may have found all the pieces to the puzzle. I just need a little help putting them together.
The idea for my project is to start with a Android OS wrist watch and install OTR plugin & messenger. Lastly i will need the the OS to be somehow LIVE as to see it does not save any type of data (logs). I'm wondering how possible it would be to boot the OS from a SD-card ?.
So there it is i'll list all the hardware and see if anyone can come up with a simple fix. I appreciate greatly any time or opinions anyone has to offer.
Android Wrist Watch - Z1 Android Wrist Watch Mobile Phone
CPU / Memory / Operating System
MediaTek MT-6513 650MHz Dual Core Processor
DDR: 4GB ROM; 2GB RAM;
FREE 8GB MicroSD Card
Android 2.2 Froyo Operating System
SD CARD
I plan to use the WIFI function of the watch to connect when needed to chat with IM.
To my knowledge IM+ supports OTR plugin.

Hi fellas.
Long story short: I seek detailed information about how LMK and especially Virtual Memory works so I can educate myself for teletubbic purposes.
Details:
I'm my old, 1gb Samsung Galaxy S3 device I suffer quite a lot because of poor ram management. Slow insufficient memory for even 1 app ooorr app transitions(multitasking), laggy apps, out of memory reboots drains my will to live.
So time to time I searched internet (especially most of the XDA forums) to find a solution for this, for months(again, time to time). In this process I learned a LOT but unfortunately its not enough since I still haven't found what some virtual memory values and related build prop entries does. Some people made guides but it's not specific and explanatory enough, unfortunately. Just some basic info from surface.
There are a lot of apps and roms that claims to provide better ram management through different ways but as you might guess, none of them completely solved my problems.
Don't get me wrong. I know that at the and, it all comes down to my 1gb device. But through my whole Android experience, I know what this device is capable of. So.. Yeah.
I want specific amounts of apps to stay in memory.
I want my system to kill apps without a second thought in out if memory situations. Fast as if I use "force stop" button in Apps/Settings. (this is important, huh)
I want to set priority to apps about using memory according to app's needs and my use frequency.
To do all of that, instead of crying in forums, I want to educate myself about ram management and do my thing by myself by optimizing system to the end.
Any help, guides, links, courses, piece of info appreciated.
Thanks in advance
