Typo for 313, but 312[.5] ((1280/(cos(arctan(9/16)*4.7) is more accurate anyway. Corrected, thanks!

I'm working on a fix for the multitasking issue, I think I may be on to a very simple "fix", but it's not perfect, but it is better.

To address about the GS3, I was very heavily debating the GS3, and still am. However, given Samsung's history of weak radios that kind of blows any performance increase out of the water in my opinion. An extra GB of RAM sounds great, but when a phone doesn't have great connectivity (I'm still amazed at the increase in performance in ALL the radios on the LTEvo)

Although, the mutitasking issue might be a moot point for me anyway, as I've always been a fan of CM, and CM9 is looking to be shaping up REALLY nice.

Linaro Android Nearly Doubles ICS Performance, And Now Parts Of It Are Being Added to CM9

Yes, actually I was planning on it already. After I get it set up to my liking I'm going to give a very detailed review.

Waiting eagerly for your feedback

(trying to figure out whether to get SGS3 or EVO LTE
SGS3 - better multitasking, possibility (at least in theory) of global roaming by unlocking SIM (since vzn claims they will do it, it should be possible for sprint version to do so as well)
EVO LTE - better UI (my opinion), usually more timely updates/support, better display/camera)

Yes, I read http://androidforums.com/htc-evo-4g-lte/542768-compare-contrast-opinions-gsiii-vs-evo-4g-lte.html

This is the one thing I can't stand about the evo... Literally every time I go to one of my recent apps.. It reloads the Page.. Super annoying... This definetly can't be what they intended

Yes. I just upgraded to the EVO 4G LTE from HTC hero. When I have games open and return to them via recent apps, they do not take me back to where I left them...they restart. I didn't have this issue with the Hero, I now feel like I actually received a downgrade. Multi tasking is impossible.

Someone mentioned multitasking with the game Cartoon Wars -- I was curious and tried it both on my Evo 3D and the Evo LTE. The Evo 3D can successfully multitask it with a few different apps, but the LTE cannot.

Does anyone know if the One X folks have made any progress on this?

I'm running various tests on this using a One X rom modified for the LTEvo, but I'm testing various configurations, and it's too soon to give my version of the cookbook to solve this.

FWIW, I can say that I was unable to re-enter video streams for a service I subscribe to (anime) on stock, but now, I can hit Home, try something else, and go back into that video, in progress, just like I could on the 3vo.

So, I'm close, and it will require root, but it's looking very doable.

IOWA is definitely looking at the same thing, pretty sure novox77 is as well, and I know other rooters are, so, my point is a few of us are looking at different angles on how to do that, from different directions.

My issues were -

  • 3-dot invasive screen menu bar (solved - it's gone)
  • remapping hardware buttons (solved)
    • long press Home bring up menu from anywhere
    • long press multitasking (recent apps) button brings up QuickDesk
      • My preferred widgets, including Google search, and apps come up regardless of whether at homescreen or inside another app
    • rom I'm using gives a lot of flexibility on this, those are just my personal choices
  • multitasking (in-progress, and a lot of positive data points/successful trials)
  • battery life (must work right with multitasking fix selected)


So, that's where I'm at, fwiw.

PS - I've got a long press on the recent apps button bringing up QuickDesk, and I'm able to run some apps, launch QuickDesk to run others on the fly, exit them, and return to my running app in progress, no trouble for many apps. Given where I started on this one, that's not a bad report right there.

Earlymon, is it the case that the One X folks have gotten/figured out a fix and you're working on implementing a similar solution for the Evo? Or is it more that your testing and experimentation is attempting to pave new ground for the One X and Evo alike?

Maybe somewhere in between is a better answer.

The dev community for the One X and the LTEvo are both working at improving performance, but that's subjective. Many seem to trying to improve multitasking, other seem to be going for speed and smoothness, others are going for combinations, some are going for Sense implementations, others are providing hybrid Sense/Senseless - on some roms, everything works, on others everything works with caveats, and on others there are clear call-outs to work in progress.

So, rather than my usual tricks of doing whatever I needed under the hood for me (and often forgetting where my notes were months later), I decided on a different approach.

I had the following criteria -

  • all functions had to work, as good as stock
  • Sense 4 customizations that I hated (3 dot bar, buttons etc) easily fixed, along with missing features
    • this I got with the Charmeleon rom
    • no special skills required or flash this, superwipe that, stand on your head on Tuesday combo of tweak flashes that we usually face
    • it adds a set of customizations with a combo of either on/off buttons or menu selections that you use like a normal human while your phone is running, and the interface is clear and straightforward, very friendly
  • Sense launcher and Sense widgets intact
    • At present, I'm in retreat on that, I'm using the Nova launcher
    • Biggest challenge was the Sense clock and after searching like crazy, I'm likely to recommend anything by Droid27 in the Store
    • My present homescreen is here
  • and finally, full and comprehensive multitasking
  • that anyone can get to with a series of 1,2,3,4 rooting and flashing steps
    • must be easy for everyone
  • people wanting more or better or best are free to flash one of the integrated roms of their preference (taking what the rom dev gives them)


Getting multitasking to work is a matter of adjusting a combination of -
  • Android memory limits that shuffle out or kills apps based on memory numbers (out of memory limits)
  • virtual memory management limits
  • adjusting cpu performance to respect the limits change (kernel cpu parameter adjustments)


The One X devs seem to have used two approaches - selecting from settings used by a Swiss Army Knife called the V6 Supercharger - or by adjusting various parameters on their own, the latter being what the present LTEvo devs are beginning to focus on.


The V6 Supercharger showed a lot of promise and I probably already have a settings combo sufficient for most people, but I was unsatisfied with what my combo (of everything) in particular did to battery life, so I'm trying some of the tricks under investigation by LTEvo dev -viperboy-. (just started that today, nothing to report yet)


IOWA is looking at doing the same thing by rolling his own set of multitasking tweaks (rather than my choose from the menu approach), and he's told me that he ought to be able to script them/bat file them so that they're accessible to anyone as well. Neither is asking for the other's numbers, I think we both want to wait until the end to compare notes - a parallax view on the problem, if you will.


TL/DR -


I'm going for an easy to flash, easy to install, easy to use, combo of things available from the dev community to solve the problem.


My criteria are - at least 12 web pages at once (16 preferred), with the ability to switch back and forth with a video stream and a game (both in progress) without either bailing out on the user (me) and without the launcher losing its mind - all without lag, all with acceptable losses in battery life (because something has to give somewhere).


I think if I can hit that reliably, then most folks can be happy.


FWIW - I could crash Sense 3 and about anything else on my 3vo if you just ask me to, all it takes is loading a lot stuff (20 web pages per session is very common for me).


Sorry for the long reply, hope this clarifies and is what folks might be interested in.

@EarlyMon:
This is exactly what I would love to see on this phone! I've been laying low with flashing ROMs and mods right now until things settle in a little bit, plus I just haven't had the time to tinker.
Is it your intent to find what works best to fit your criteria, then put together "cookbook" for the rest of us to follow to achieve the same results?
Also, any particular reason you recommend Droid27's clock/weather widgets over others, such as Beautiful Widgets? The only drawback I see with BW is that there is no animated "flip" on the flip-clock when the time changes. Small detail, but I'm a sucker for things like that.

Just wanted to add that the results I'm getting are better, but by no means comprehensive or near solved. I think this is going to take a multi-pronged approach that is above my 'paygrade', unless I dive into kernel development. There's a first for everything though.

Welcome to the forums!

The target is a cookbook, yes.

Droid27's are free, and I want to offer a free solution. The other free alternatives were visually or functionally deficient,and many of the paid ones were no better. BW is great, go with that if it suits you. Droid27's lacks the variety of widgets but has a lot appearance choices and works exceptionally well.

Thanks! I'm fairly active over on AndroidCentral (same username), but have been lurking over here a bit too. Your dev section seems to be a bit more active here than what's currently over there so I decided I'd jump in.

Got it on the free solution. I bought BW a long time ago on my first android (Optimus S), so it's available and I'm very familiar with it.

I really hope you guys achieve what you're setting out to do. I was running a tweaked/patched/cobbled-together alpha port of CM9 on my Optimus, and as much as I liked it, the constant flakiness was starting to test my patience a bit. So I'm enjoying having something that is 100% functional right now (multitasking notwithstanding). I enjoy tinkering with things, but I'm going to sit back a little bit and wait for the real experts to come out with something fully baked before I start getting flash-happy again.

Thanks for your efforts on this!

Has this issue been brought to HTC's attention? Maybe they can work on an ota update with multitasking fixes.

Yep - HTC Addresses Multitasking Concerns For One X and S – Calls It “Sense” Optimized

Quote:
HTC is aware of some questions in the enthusiast community about how the HTC One X handles multitasking and memory management for background apps. We value the community’s input and are always looking for ways to enhance customers’ experience with our devices. That said, right now multitasking is operating normally according to our custom memory management specifications which balance core ICS features with a consistent HTC Sense experience.
(ps, for those who didn't like the neon theme on that Droid27 I used, I've updated my screen shot to show something a little more conventional, but still not straight Sense clock widget (trust me, it has one))

I really hope they do something.. Even if it really is working as planned.. It could definetly use a change.. This is my one and ONLY gripe with this phone.. But when I weigh evrything else that I love about this phone... It doesn't bother me as much.. This will for sure be the first time I keep a device for a full 2 years.. I can say that with confidence

Towards the end my sense reloaded all the time on my EVO 3D I hated now. Today it did it twice on the LTE and has done it a couple other times. What makes this happen. Someone told me on my 3D any apps that I moved to SD card that had an X on them move them back to phone and then I was told if you have alot of widgets. I used to have some memory booster app to free up ram is that good to have. And when I am done with an app is it best to always hit the back button all the way out instead of going to the home screen? Thanks!

It's reloading because there's not room for the apps you're using and Sense - so it reloads Sense when needed.

Don't use memory boosters or task killers, that will make the problem worse overall.

So an app like this I shouldn't get Android Assistant(18 features) | AppBrain Android Market

I have a habit of hitting my home button alot and not backing out of apps but I should back out right? I love this phone and it just reloaded again when I unlocked the phone just now. I'll deal with it I'm still glad I got this phone it's great. I know to not use task killers but why does out phone come with task like our 3D did? I never have downloaded one but I have used a memory booster to help the memory but then I deleted it also on my 3D after all my reloading problems.

That looks like a handy monitor and some things, like a cache cleaner or browser history cleaner, are perfectly ok. Just not memory managers or add-on task killers.

Apps use memory in the Linux services - if you go to settings, apps, find your app and Force close it, all memory for the app will be cleared properly - most all add-ons are hacks and don't do it right.

Monitor and task management tools vary wildly in their ability to tell the truth. Some will report actual ram memory used, others are actually reporting cached memory (as when an app is parked and not in ram) - killing or playing with apps that are parked in cache do nothing to help actual used ram at that instant - it just confuses the operating system.

If you don't see a problem hitting home instead of the back key, then don't sweat it. When you hit home, you're leaving many apps running - for some apps, there is no difference between home and the back key. If you home out of an app where it does matter, and you don't go back to it for a while, Android will sense that it's been idle and simply shuffle it out of ram to cache and leave a little ... let's call it an "address card" (very few bytes in memory) that tells the operating system where to go into cache to restore your app to the state it was once in. If it sits unused for too long, even that gets all cleared out.

The point is - Android tries to run as many things at once as it sensibly can. Because it knows it's not running on a PC with big memory and a hard disk, it will move things in and out of ram so that whatever you're running now will run efficiently (unlike Windows, where if you start running enough stuff, everything can slow down a lot) - but it gets that efficiency by putting apps to sleep, caching them and then even auto-killing them.

Android multitasking, as I've just described it above, is controlled by a set of complicated numbers that basically say what to do when and by how much. Those numbers are things that IOWA, myself, others and the dev community are tinkering with. The numbers are like a Rubic's cube - we want to solve as many sides of the puzzle as possible, not just one.

Ok, I hope this is all accessible and makes a lick of sense. If not, it's my obtuse writing style, not you, feedback what's unclear and I and/or others will hope to clarify.

PS - cache is a hidden part of the phone's 16 GB of storage, it's not ram.

Biggest issue I had with multitasking is a couple of time when several things were open and I pressed multitasking button to see what was there once I slide up to apps the other apps that were there the icon either didn't show up or it was something else like maps had no icon gmail had phone icon pressed multitasking button again and once more to jump back in and it was fine

Well I just don't like when my sense reloads just cause it did it all the time on my 3D but on this phone since I've had it only a few times recently. So I thought maybe not backing out and going right to home had something to do with it I don't really know. But I'm still having trouble with text not sending sometimes and I am trying to send a picture now and it won't send. At work on my 3D there were always 2 spots i could go to to make my text send and I got text to come through on this phone they won't send and last night all at once after I had just gotten home all my text came through at once. My friend said maybe it's my phone I should trade it in for a new one. I hate to do that since I have everything on it already. But I don't know if an update will fix it or once we get LTE it will be better I don't know what to do.

Texts ought not be affected by any multitasking. To narrow in on that, please if you can, hold down your power button for a good ten seconds - eventually, the capacitive buttons will flash and then your phone will reboot - that's the same thing as a battery pull on this phone. Then, go a day using only the phone and sms, nothing else, see if you can find any change in how texts are working out for you. Let us know what you find.

Meanwhile - news from the root multitasking trenches after hours under the hood on my phone monitoring everything -

As it turns out, it seems one dev is making a mistake on how his settings are for multitasking (his mods are not actually taking hold), and other devs have seem to have some settings that are in conflict with one another on this.

I've contacted those involved, so with a little luck, we may have some solutions to those issues pretty quickly.

I'm testing what I hope could be the final, simple cookbook now.

So here's my relative finds so far.

I've set the android auto memory thresholds to the following, and it's improved multitasking a bit.

Foreground Application : 10MB
Visible Application: 12MB
Secondary Server : 20 MB
Content Provider : 40MB
Empty Application: 64MB

I've also lowered the VM Heap to 96MB from 128MB. (Considered the default VM Heap on my Shift was only 32MB, 96MB is still HUGE.)

There are a variety of ways you can tweak these settings, and if this stays consistent for the next week or so I'll write a batch zip that can apply these settings permanently. If that works, I'll post it on AF.

By the way - when we talk about multitasking, we're talking about what's apparent to the user.

Android multitasks, and it's often surprising for those unaware of how much is going on under the hood.

At the moment, I'm running a set of tests that involve streaming video with audio on headset, Talk session mirrored from my desktop to see if Talk notifications come in (yep, they do ), two system monitors running, a browser, and another streaming vid from another app all queued up and ready to go. Those are my apps, in addition to the messaging, time, weather and phone services running, as well as the launcher, of course.

Here's the list of processes that that really shakes out to -






Anyway - the above shows why I said that tinkering with memory parameters is like playing with a Rubic's cube.

So, I took the Evo 3D settings and tweaked the last two, kept the others, not terrible.



I'm able to leave and re-enter video streams without losing my place and also keep 7 web pages open without my browser losing its mind.

Did you try restarting the phone? I did that and it fixed my reloading issues. I know to do that now when sense starts to act all wonky.

Also from another thread on AF:

settings>developer options and under Application settings make sure Don't Keep Activities is unchecked and Background Process Limit is set to use the Standard Limit option. Once this is done, restart your Evo 46 LTE by holding the power button and choosing restart.

It's very frustrating expescially when I'm trying to show off my new phone and getting the loading screen. What gives? I have done a factory reset, cleared the google wallet, just in case. But it happens just about everytime I browse a few pages on dolphin, looking through pulse etc.

I have rebooted my phone but I just checked my developer settings and they were what they were suppose to be. I also didn't know about holding the power button down for 10 seconds and seeing the buttons flash was like a battery pull so I did that. I am still getting an occasional sense reload not sure if I got any today maybe once I forget but all my text have been sending today so that's good.

I still love this phone. I was at a concert last night inside of Belterra casino and I had no signal at all couldn't upload a pic or anything but once it was over and I got to the slot machines it was working fine good 3G. But if I have no 3G signal shouldn't I roam and be able to do stuff? That confuses me I know we roam on Verizon so maybe Verizon people didn't have a signal too I don't know. At my work AT&T people have signals where mine don't. But I love Sprint and there unlimited data so I'll with Sprint. This phone is great!

I think you're in a poor signal area and that's all there is.

I hope I'm not going over ground already covered or using the wrong thread, but exactly what happens when you "toss" a card from the multitasking "deck"? It doesn't seem to kill the task like task manager.

In some ways, it works better. It will completely remove a fresh app from memory, and it will remove the stub of one sleeping. The HTC Task Manager doesn't accurately display running apps, and the multitasking deck only shows apps you've opened.

Hm. Well for example, there is a glitch I get with the facebook app. When I take a photo and upload it to facebook using the facebook app (not facebook for sense), it sometimes will show two progress bars in notifications, of which only one will move. It will complete and erase, but the second progress bar will remain indefinitely in notifications. The only way I have found to remove that dead notification is to kill the facebook app with task manager. Flicking it out of the multitasking deck doesn't do it.

Yeah I know that especially in my house and at work. I use wifi always when I can though. But out of town at this casino with no free wifi it really sucked in one spot. But another concert here in town last week it worked better than my 3D and was uploading pics to FB and doing good so it varied I guess. But I am not giving up this phone or Sprint's unlimited data just for a not so good signal in a few spots. LOL! I love this phone. We never got 4G here but it worked in one or two spots by my house it was weird. I really hope LTE gets here at least by next year like they say. Now I know this has been asked but if you don't have LTE your phone should be on CDMA only right? Someone said 3G is better with that on but I think I had it on and then put it back. I do have my NFC still on though was messing with Android Beam and knew I was gonna try the tags here soon so I left it on and haven't noticed a difference in battery drain with it on.

Rose - the CDMA with LTE on/off has some discussion about which speed is better, but those results are anecdotal - and connectivity ought not be affected, but if you find a setting that works better, go for it because we don't know exactly what's going on the hood for radio management. Use what works for you.

I think that's part of a known Facebook bug that is addressed in the viperROM for rooted users - sorry, I don't use FB, just passing on my understanding from reading others comments.

I have now seen a couple other glitches that left notifications and required task termination, which tossing from the multitask deck did not solve while killing in task manager did. In particular, I ran into the issue with a Jetcet print task earlier, which glitched out with my printer and was unable to print.

Speaking of which, now I'm on the lookout for a fix there. I like the Jetcet integration.

Yeah I've noticed that too when uploading a pic to FB I see it up top and it says on going and I usually just reboot my phone and it's gone. I also see the one that moves and says 100% and the one stays at the top and it says ongoing.

You should be able to get rid of it by killing facebook with the task manager.

Thanks, I saw you wrote that. I was restarting phone where it closed all apps and rebooted. But I guess that's quicker and easier.

Content Provider : 40MB
Empty Application: 64MB

I've also lowered the VM Heap to 96MB from 128MB. (Considered the default VM Heap on my Shift was only 32MB, 96MB is still HUGE.)

There are a variety of ways you can tweak these settings, and if this stays consistent for the next week or so I'll write a batch zip that can apply these settings permanently. If that works, I'll post it on AF.

Cool. Does anyone have any links to provide so I get learn how you guys are able to mess with these settings? I'm very intrigued.

Wouldn't lowering the heap in the VM cause garbage collection to occur more frequently?

The VM heap is what each 'sandbox' is allowed to take up as a maximum.

So by lowering the heap, (in theory anyway) Android will move RAM around inside that application to accommodate that VM heap instead of killing other applications.

This allows more RAM to be left over for other applications by limiting how much RAM an application can have. This is very useful for memory hungry apps like the browsers or games.

The default VM Heap of 128Meg is the largest I've ever seen, and I'm still playing with VM heap sizes to determine the best fit.

Given the VM Heap used on my three phones with 512mb RAM(Epic, OG Evo, and Shift) was between 32 and 48 mb, a VM Heap size of 96mb is still huge by comparison.

With this being said, I have noticed improved multitasking performance with these settings(actually tweaked them a bit more).

Between EarlyMon and I we should be able to find the 'sweet spot' as he's doing his own experiments using his own values. FWIW our current values are very similar, and we're both getting better results than before.

Lowering the VM heapsize can increase the number of smaller apps running at once and provide faster response switching between them, but can lead to crashes on memory intensive apps. For those, a larger heapsize is needed to prevent crashing.

Again, it's part of the necessary balancing act.

If you are rooted, make frequent nandroid backups, and don't care about driving your rom to crashing and you're using the stock rom, then you can try Rom Toolbox. If you don't know what you're doing and don't make nandroid backups then you ought not even consider experimenting.

I just wanted to let people know that i have not had this issue much at all after removing the stock widgets from all the home screens.

Also, the stock browser doesn't always reload open tabs, now. It still does occasionaly, though.

I only have friendstream, gmail, and google search widgets on 3 different screens. One other good thing since doing this is the gmail widget actually updates now. It used to show the same emails from when I first loaded it and would only update when Sense had to redraw, which was getting quite annoying.

I ticked the 2D option and will let you know of anything different that I notice.
