Applications?

Why don't all app's have a exit or close? Take Facebook for instance once, you load that app it stays open no way to close it and taking up battery. Is there a app so you can have theses close.

For crying out loud, search a little. You have a rooted device running Leo Droid and yet NO IDEA how Android manages applications? There are a plethora of task killers (-> google it) around, but also everybody knows they are not needed (-> google it).
Don't get me wrong, I know that not knowing stuff is a perfectly natural thing for a human being (after all, I am a teacher). But in this day and age of information being readily available at the click of your mouse (Google et consortes, this forum's "Search" button...) you still need someone to find/type in the answer to YOUR QUESTION so that you get it on a platter... Sigh.

Multitasking the Android Way
http://android-developers.blogspot.com/2010/04/multitasking-android-way.html
P.S Do NOT use any of those task killers on your 2.1 or later versions of Android phone!
Cheers!

Concerning Facebook I totally understand his complain. Even with disabled notifications and "leaving" the app via backbutton it is listed as the highest battery-consumer (under*#*#4636#*#* --> battery usage while idle).
Since I didn't find a solution for that I uninstalled Facebook. But the other guys are right, as long as an app is programmed well, it does nothing in background and sleeps. No need to close apps or free RAM. Free RAM is always a sign of bad memory management in the OS so keep it filled up as it will speed up your phone!

Thanks facebook is high battery consumer, never used a task killer and I never will.

I have installed the facebook-app and it is no battery drainer for me.
Go to chat, then menu -> go offline.

if the app is closed then it won't sync up itself will it? (or if it does it'll just restart itself again).
say you have facebook to sync each hour - I thought the hour was from open...
so open check news feed, back out of it (facebook still running), after running for an hour it will check again and notify you if you have notifications on...
The only thing that does seem to annoy me slightly is when I open improved email it seems to open a whole host of other apps at the same time, including soundhound, stocks, maps, and about 10 other things... no idea why as it doesn't need those apps opening at all

1 GB RAM? Deception.

I understand that Android memory management cannot be compared with Windows memory management. CHECK
I therefore don't care that my SGN always shows about 100 MB free RAM (according to Quick System Info Pro) because you know, it's only a number. CHECK
I dont't have any lag when starting and switching (most) apps on my SGN. CHECK
I have installed only the most important apps (for me). Counting only those running as a service/widget and therefore needing some RAM permanently: Live wallpaper, Light Flow, Calendar Widget. CHECK
BUT:
Pressing "recent tasks" while BROWSING (e.g. opera mobile) and switching to another app like "google reader" causes opera mobile to close in background. And every restart takes about 2 sec and a reload of every web page tab.
So 100 MB free RAM is not just a number - it's a major problem for me. My previous device: HTC Desire on CM7.1 and I could not remember that a simple task switch closing opera in over 1 year!!!
Android 4.0.1 always seems to close the app that uses most RAM - and that's Opera. The task manager shows at least 4 other unused apps (settings, google mail - no widgets used) that use 120 MB in total that DO NOT get killed!! Even if they are unused for quite a while. Don't you think too that Android should priorize the foreground app and the last used foreground app instead of apps that have not been shown for minutes? Isn't switching between too apps the most common use case? SGN's "1 GB RAM" is pure deception to me. It's what Samsung has built into the device but not what you really get.
How do you cope?
[Sorry for my bad English but it just flowed out of my angry fingers]

I haven't had any problems with this whatsoever. Try closing tasks yourself so the system isn't forced to close one for you? Worth a shot.

Closing tasks before surfing is not what I want to do on a high-end device with 1 GB RAM. I want to use at least 2 apps concurrently and I think that this is not much to expect...

I typically have 275-300+ MB free at any given time (according to the settings page).
Not sure how your managing to use so much. I've yet to have android have to close a app for me.

Solution: Use a different browser.

Same problem here, and I didn't cope I created my own mod of Opera Mobile where I added a service which increases the OOM priority of the app. Android then don't close it anymore.
Link to my Opera Mobile "keep-in-memory" mod: http://www.reddit.com/r/Android/comments/n7p48/app_mod_by_requests_latest_opera_mobile1153_with

That's the issue. The value of Opera is set too low where the Android system will close it first over other processes. It doesn't care that it is Opera, just what the value is. You can check all that with Auto killer memory optimizer.

Settings page seems to calculate the free RAM differently ("wrong"?)
Oh and changing my browser is not a solution - happens too on stock browser.

Auto Killer shows that Opera will be the process most likely to get killed, that's true.
But why is it that killing is needed so often?

Already asked but nobody answered.Settings in my phone shows above 300mb and with elixir2,autokiller memory optimizer and few other apps shows below 200mb.Dont know which one is correct.
And one more question. My sgs2 has all the time free ram +450mb.Why GN has below or around 300mb (if settings correctly report the ram) with almost same apps installed?

restart the phone and tell us the memory value as soon as you restart without opening any apps

I don't think Android sets the values. It the app itself. So they programmed it whereas they wanted it closed more often than not. Like someone said, you can reconfigure the app the raise the value.

I did a reboot (first one since 3 days when I unboxed the device, it's so damn stable :-D ) and know I've got ~ 200 MB free too. Maybe I had a leaking process which led to this problem??

more than likely. its probably an app that really isnt made for ICS.
or it could've been an app with a high value for keeping in memory that was using quite a bit and would never close (games are usually set that way)

And Android works on thresholds, I'm sure you are aware. So once your device gets to a certain memory level, it starts to kill processes with low priority. So maybe you have too many things running in the background or Widgets. Get rid of things you really don't use because they could be using resources.
I'm using a Droid RAZR, which is bogged down wth Motorola stuff, but auto killer still reports 315 MB of ram. I've frozen much of the bloat though.

You don't set the value, Android does that based on requrements of the application, what type of application it is, and what state it is in.
What I did with my Opera Mobile mod, was to add a dummy service with high priority that don't do anything. This sets the OOM value to 2 when Opera is not visible in the foreground, this is just slightly below the priority of the keyboard.

Why don't browser pages stay in memory?

I've been wondering why my browser tabs get kicked out of memory after so long. Usually if I take a phone call or switch into a large app and return to the browser, I have to reload all my pages. I normally have 3-5 tabs open at once. With VZW's slow 3G it's a pain to reload and lose my place. Doesn't this phone have 1GB of RAM? I wouldn't think a phone call would cause the browser to be removed from memory would it? This has been plaguing me for years just wondering if there was anything I could do to prevent it.
Sent from my Galaxy Nexus using XDA App

Yes its just something to do with the latest ICS version, memory management is more aggressive with the browser or something. It drives me mad too. Sometimes ill switch to the homescreen for one second without loading a single thing, go right back to the broeser and it was kicked from memory.

Is the behaviour the same in the new Chrome Beta?

Yup, I find this a bit annoying, too.

It doesn't seem to be. I've just had a test and it seems to keep all pages open.

Open browser -> load page -> menu -> save for offline reading

But wouldn't you then have to do this for each tab?

Because Android doesn't offer true multitasking. It closes apps you are actively using and caches apps you don't ever use... Poor memory management and aggressive task closing makes for a poor user experience.

Yep. It's a little too aggressive. It's most annoying when i'm using Spotify or something. I might pause the music for a little while for whatever reason, run a couple apps. When I go back to Spotify I have to restart the whole app.
It should intelligently monitor usage and cache apps based off that...

Hmm. I have never used Spotify before, but that sounds way too aggressive. I use slacker.com and if i pause it there does not seem to ever be a problem going back and having the song pick up right where i left off. Google listen seems to do the same. Now don't get me started on the one or two times per day slacker causes my galaxy nexus to reboot ......

[Q] Can anyone tell me is this OK or my RAM is vanishing!!!?

I got HTC One V for me and now after 3 days, just 45MB of RAM is FREE. No apps are running / opened.
Also when I touch the 'home' button on the bottom of the screen, it says 'loading' and after about 10 seconds of waiting, the home screen appears. WHY IS THIS HAPPENING TO ME?

That's quite unusual. When idling with no apps open, my phone has anything from 50 - 120 mb of RAM free. Could you provide more details that would help us identify the problem (i.e anything you've downloaded/modified recently, screenshots of your task manager page, running any custom launchers, any custom ROMs, rooted/unrooted etc.)

You have also apps that are running on Cache slot. See first screen? Go to that again, press menu on your phone to bring up the menu screen and select Show cached processes. Also, it is a good advice to restart your phone once in awhile. Just to make sure that the cache is rebuilt and the ram is defragmented.
Cheers

Galaxy Nexus multitasking issue

Android is praised for having 'real' multitasking. But why does it have to 'suck' on a phone with 1GB memory?
Chrome starts to reload 3-4 tabs only if it's the only app 'opened' (of course there are other background services. but I don't have much running services, map, google messaging service, keyboard, )
I think it could also be problem with app. app not releasing memory resource when goes to background.
But it's really annoying to see that apps activity needs to be created again from scratch after opening a few apps.
Please discuss your opinion here.

I don't have facebook running as I've said earlier. I don't even have it installed.
But I"m still not convinced that it's the BEST android multitasking could have. it's too aggressively killing background activity..

Get autokiller from the market and adjust the settings then. You want lower numbers in the app to allow more applications to stay active. Note that some apps might just kill background memory use, there's nothing you can do about that one.
Doing this might make your phone more laggy. You need to decide for yourself what the best trade-off is for you.

When exactly does it do it? I have 5 tabs open and I'm good! Is it after a while of inactivity?

It's not a refresh (like refresh web page), I think it's just re-rendered from the cache..
even though I'm android fan, I'm jealous how iOS manage to run pretty well for daily use with 512MB... probably dalvik JIT is culprit here?

I personally think this is a problem with chrome and this is the reason I don't like chrome because it runs a constant large service at 70+ mb at all times which takes away from general multitasking of the phone. My guess is this is related to your problem. Persistent services on android are rather powerful and when one is too large it has detrimental effects. Maybe others don't experience this with chrome, but I did, and that's why I stopped using it.

Yes, chrome is worse than stock browser.
Stock can maintain usually 4-5 tabs easily without reloading.
Hopefully Google could do something with both chrome and improve OS multitasking capability.
