By far the best multitasking mobile OS is webOS. If a card is open and is anything other than a video, then it's running in the background unless the developer specifically codes it to suspend. Since I switched to Android, this is the one thing I miss the most about webOS.

For me, the only problem with how Android multitasks is with Quickoffice and Polaris Office. Try this: create a new document, add some text, and then start switching back and forth between it and other apps. Eventually (sometimes immediately) you'll return to a blank document, with no way to retrieve any edits. It's the same for a document that's been saved, and really limits how an Android device can be used to write long-form pieces while doing other things. Basically, you have to save every time before you switch to a different app (say, to look up some research).

In webOS, you'd just keep the card open and your document would be retained. And note: I'm not here to bash Android or glorify webOS. I did switch, after all. But man, either developers or Google have to fix this. At the very least, an app like Quickoffice should save its state when it's suspended, to include the currently open document. It doesn't actually have to run in the background, but it certainly shouldn't lose information.

Given how I'm using the Transformer, this a huge thing for me. I wouldn't switch to, say, the Touchpad, because webOS doesn't even have apps like this yet and probably won't for awhile. It might have Quickoffice sometime in the next few months, but that's about it. Oh, and the Touchpad is a weak tablet as well, and certainly doesn't have anything like the keyboard dock available. It's just that Google and the Android development community could learn a thing or two from webOS, starting with better multitasking support.

Okay, venting over. I feel much better now. :)
[Eee Pad Transformer General] EP2008:
I was just using the Playbook at staples and it also has the browser multitask problem... when I open a bunch of tabs (cnn, bbc, globeandmail, espn, etc.) and go to another app, returning to the browser causes all tabs to refresh - it's actually worse than on android because at least on android the tabs can remain "active" without the need to refresh SOME to MOST of the time.

So the illusion of multitasking remains on all mobile os's.
[Eee Pad Transformer General] diversificationied:
Multitasking means services running in the background. Which Android can, and does do. It does not mean having every single process and application running live in the background(who wants that anyways? not even windows does multi tasking like that anymore.).
[Eee Pad Transformer General] EP2008:
Yes, light services that check for certain notifications is one thing, but apps that were run in the last 5 minutes should not close so quickly. In the meantime, I have a lot of services running and taking up memory that I DON'T want - I wish there was a way to adjust what apps stay in the memory (and which never load automatically), even if it does mean having to manually manage memory usage, I would rather it truly multitask than "fake it".
[Eee Pad Transformer General] diversificationied:
Apps don't close, they are hibernated. If an app restarts from zero, it's a problem of the developer not implementing their save states properly. (I believe engadget app is notorious for this).

The concept of "closing" an app doesn't really exist. The closest thing is a force close, which is just removing it from memory.

There are a few apps that allow you tweak the thresholds, but they require root if I remember correctly.
[Eee Pad Transformer General] Mutnat:
Maybe even if it could use some of the 16/32 GB storage as a swap file it would help. It wouldn't slow the system down much since it's not on a magnetic platter like on a PC. I'd gladly give up a gig or two of my 32GB for a swap file if it meant the apps (or browser tabs) I was working with wouldn't get unloaded from memory while I was using them.
[Eee Pad Transformer General] EP2008:
Archos did this on their 256mb ram devices (added 32mb swap I believe). It did absolutely nothing on those devices, but maybe a gig or two would make a difference. I'm willing to sacrifice some battery life and speed for a true multitasking device.
[Eee Pad Transformer General] wynand32:
I hear you, and I do wish Quickoffice and Polaris Office would handle this correctly. That's really my only concern with Android, that these apps lose edits and new text with frustrating regularity.
[Eee Pad Transformer General] xufuchang:
illusion multitasking ? lol

want to see fake multitasking ,look at ios,it fakes it. but android is pure multitasking. multitasking allows app to still running and finish it's process in the background. try open a browser,load a rich content page, change to other app,wait for few second n backt to browser,the page should be loaded.

case when ur app won't continue from previous state just because android has its own way to kill processes, this is merely due to memory management.
[Eee Pad Transformer General] EP2008:
But the point is, if I return to the browser more than just a few seconds later, it restarts and then reloads all my tabs - this isn't multitasking. With the amount of RAM we have on these devices, apps shouldn't be closing so aggressively - and worse yet, apps that I don't want in memory shouldn't be taking RAM away from important 'active' apps!
[Eee Pad Transformer General] xufuchang:
yes some apps just buggy, even honehcomb itself isn't perfect. but multitasking sure is working in android.
[Eee Pad Transformer General] jerrykur:
That sounds like a design flaw in the applications. What happens when you switch to another application is the application being pushed into the background receives an OnPause() event. The application should handle this event by saving the user context in a manner that ensure no loss of data (ex write to the drive) and free resources. When you make the application the active you move it to the top of the activity stack and the app receives and OnResume() event. The app should handle this event by restoring the user context to the saved state.

This is all very well documented in the Android API along with the expectations of the actions the application should take. However, a developer can choose to ignore the recommendations.
[Eee Pad Transformer General] wynand32:
Thanks for the explanation. I'm surprised then that these particular apps are having the problem--I mean, Quickoffice should know better, right?

Well, I've reported the issue, perhaps they'll resolve it.
[Eee Pad Transformer General] galtom:
Can someone clarify this for me... (as I am used to Windows).

Let say I will start task like zip/unzip of a file/files or download of a file from the net. Can I do something different in the meantime and wait for the task to finish in the background?
[Eee Pad Transformer General] jerrykur:
Absolutely. I do this all the time.

There seems to be people confusing what an application does versus what the Android OS does. The OS supports multitasking which is running multiple tasks at once. It will switch between tasks as required. Your example of a file transfer is a perfect illustration. You start the file transfer and then switch over to reading your mail. The file transfer continues running and the OS switches back and forth between the file transfer and mail applications as required.

This OS multitasking has nothing to do with an application failing to remember what it was doing when another application runs. That is an application design issue and should be addresses by the application's developer. There may be very good reasons for the application to not maintain it's context when the user comes back to the application, but that decision is specific to the application.

[Eee Pad Transformer General] galtom:
Thanks for clarification of the issue.

Since we are on the subject (in a way)... are there available for Android following apps:

zip/unzip/rar/unrar - thing :-)

download manager that works with hosting sites like filesonic or others?
[Eee Pad Transformer General] ZaelFaroe:
Check out androZip for the first one. I have no idea on the second.

On the topic of multitasking on Android, there is a big difference between what are called activities and services. In android an activity is what holds a view and presents a user interface. Activities are only gaurenteed to be kept in memory while the user is viewing them. There is limited multi-tasking support in that they are kept in memory and the user has a list of the most recent, but an activity can easily be removed from RAM with no indication save the onPause event the activity recieves when the user leaves. As was previously mentioned, it is well documented that all data retention should be handled at the onPause.

A service is an all-together different beast. A service has no UI, and only does background processing. This is really where the multi-tasking element of android comes in. Applications like skype and gmail are composed of both an activity and a service. The service is always in the background checking occasionally for new messages or emails, and then when the user hits the icon in their notification tray the activity is opened to allow the reading of mesages and the option to reply.
[Eee Pad Transformer General] :
It could be argued that the OS should be responsible for an app maintaining integrity for the user though. Slippery slope and all that jazz.
[Eee Pad Transformer General] Magnesus:
Thats what OnPause is for.
[Eee Pad Transformer General] jerrykur:
Huh. How can the OS be responsible for the decisions an application's developer chooses to make? The OS and SDK provides a series of features and documentation on how they are intended to be used. But it is up to the developer to use features in a way that makes sense for the particulars of the application.
[Eee Pad Transformer General] EP2008:
Maybe there's some confusion over who should be handling background proceses, but Google has claimed that Android manages memory. To me, every app should be able to adequately "pause" what I was doing so it can restore back to the exact same state when I return. Merely returning to a browser to have all the pages reload isn't good enough.

[Galaxy S II Q&A, Help & Troubleshooting] CandyAndy:
Hello,

So I basically want to make a small survey that what launcher are you currently using and how is your battery life. I am trying to narrow down if some launchers are better for the battery life. I am currently using Touchwiz and get about 8 hours of moderate usage every day. Not good.

So how about you guys?
[Galaxy S II Q&A, Help & Troubleshooting] Jiia:
I used LauncherPro for a day but then removed it. It just hasn't evolved enough meanwhile TouchWiz, Sense UI and even MIUI have gone way ahead with their launchers. I don't think you will notice much difference in battery life between different launchers. LauncherPro renders stuff much faster but I don't like its appdrawer and dock.

Now I'm using TouchWiz until someone ports MIUI to SGS2.
[Galaxy S II Q&A, Help & Troubleshooting] godutch:
GO, I prefer vertical scrolling to horizontal scolling in touchwiz and like that you can sort the apps alphabetically (who on earth tought it would be a good idea to make a horizontal scrolling app drawer and sort the apps by install time!?), also the running apps (+task killer) and recent apps tab are real handy
[Galaxy S II Q&A, Help & Troubleshooting] orangejuice1982:
I'm gonna give Launcher Pro a go today. As for the scrolling, I quite like the horizontal scroll, but dislike it for seeming like the iPhone
[Galaxy S II Q&A, Help & Troubleshooting] CandyAndy:
By the way. How is the performance with some other launchers?

I used to have Go Launcher when using Desire. Now when I got this phone I first changed to Go Launcher also but then I noticed heavy battery usage and also some jerkiness with the scrolling, therefore I switched back to Touchwiz and still here. It is not THAT bad as everybody has been saying.
[Galaxy S II Q&A, Help & Troubleshooting] conantroutman:
Launcher pro paid version.

Could have easily had 24hrs moderate use yesterday.

Tbh I don't think the launcher is one of the main factors affecting battery life though.

[Galaxy S II Q&A, Help & Troubleshooting] ph00ny:
I noticed the similar jerkiness with the go launcher initially and ended up switching over to launcher pro for a bit. When i reinstalled go launcher to use the notification addon, transition was much better and the battery usage was on par with touchwiz

Builtin widgets are better with launcher pro but i like the notification addon for go launcher more.

I have both go launcher ex and launcher pro installed but the default launcher is set to go launcher
[Galaxy S II Q&A, Help & Troubleshooting] B3311:
ADW Ex. Very pleased with it.

Currently 30% battery left after 2 days 3 hours, moderate use, but have removed or frozen a lot of bloat and/or stuff I don't use (Facebook, Twitter, games). Freezing TW launcher seems to have helped hugely wrt to battery life.

On KE2 stock.
[Galaxy S II Q&A, Help & Troubleshooting] will-i-am1977:
I've got the following, adw launcher, go launcher ex,launcher 7, launcher pro, spb shell 3d and TW

[Galaxy S II Q&A, Help & Troubleshooting] poults:
I usually use go launcher but have been trying regina 3d launcher, looks nice but i should imagine it would have more of a drain on the battery although im yet to confirm that.
[Galaxy S II Q&A, Help & Troubleshooting] maranello69:
ADW Launcher EX its the best choice for me, there are many themes you can use to customize it even more, the desktop scrolling efects are just great and i love the posibility to hide the main dock and the notifications bar, the screen just looks awesome then :D
[Galaxy S II Q&A, Help & Troubleshooting] krabman:
Have had all the launchers mentioned already for a spin on the phone. I had been for the most part sticking with adw on the N1 but I was not able to get that to perform smoothly on this phone. Right now I'm actually using tw with most all of the wiz removed/frozen. I find I like it.
[Galaxy S II Q&A, Help & Troubleshooting] thetap:
ADW EX. the only con is the no-bubbles on the dock. if I receive a message I can't see it in the dock, only in the notification bar.
[Galaxy S II Q&A, Help & Troubleshooting] MaTiCeK-:
I'm using Launcher Plus Pro. It's great, but it freezes on almost every boot. Have to wait a minute for force close to pop up, then it works beautifully. I suspect it's because the SGS2 is scanning the SD cards on every boot.

Anyone , please ?

There are apps that will let your Axim act as a remote (eg. transmit commands) to devices such as TVs. And some have the ability to "learn" the IR code from a remote. So the software you're looking for is embedded in them but I don't know any standalone software.
[Windows Mobile Development and Hacking General] Dragoss91:
It doesn't matter if it's standalone or not , maybe I will manage to get those recorded codes . So , could you tell me name of those softwares please ? I have found RC II but I don't think it converts signal to HEX .

[Hero CDMA Q&A, Help & Troubleshooting] mtnchkn:
I posted a while back about the different recovery images here and have since been using Darch_RA-1.7 for everything (Firerat, GB ROMS, etc.).

When I change my custom partitions, there are two times when I need to ADB (one is arguable). I have to reboot into recovery during one point of modifying mtd partitions with Firerat Recovery, which can be accomplished by pulling the battery and just booting with HOME+POWER keys. It would be super handy though if there was a reboot into recovery command in my recovery image. I know this is in CW 3.x.

Secondly, and more important, is that to limit hickups in google restoring my settings when I load a new ROM, I need to apply s0be's fix before my first boot, which essentially is just making a dir /cache/download and then fixing the permissions for it.

I would love it if these commands could be apart of Darch's 1.7 recovery so that I could re-flash on the go without a computer for ADB shell. I am not completely sure how to do this (modifying the recovery binary), and moreover if I need to find the original source or just unpack and use the binaries. This little conversation was somewhat helpful.

Thoughts? Help?
[Hero CDMA Q&A, Help & Troubleshooting] mtnchkn:
Replying to my own post, but I had an idea that to address s0be's fix, I could possibly make it into a signed zip, of course assuming that would work (permissions?). Just a thought.
[Hero CDMA Q&A, Help & Troubleshooting] laie1472:
If your using Ra1.7 you don't have to pull the battery when using fr. Just choose the power off option and reboot with home+power. I know its off your op topic but I'd figure I'd post incase you were still using fr.

#Root/Hack-Mod_Always*
[Hero CDMA Q&A, Help & Troubleshooting] The Fer-Shiz-Nizzle:
And as for the s0be market fix, it is no longer necessary if you use firerat v1.5.8 and set your cache partition to 18
[Hero CDMA Q&A, Help & Troubleshooting] mtnchkn:
So that's why people have an 18mb cache.

Well that explains why I see a bunch of folks using 18 as the cache size, but didn't see that in the thread. My most recent repart with with 128 and 18, which although is a bit excessive for the cache (only using 4 of 18), will eliminate the need for s0be's fix.

For the record, I went ahead and did it anyways. Also, you can definitely just use the power off function (or battery pull) in Darch's 1.7 to get reboot to recovery.

Bottomline: I would say this is solved for my specific issues with Firerat MTD. Also, Darch's 1.7 is perfectly capable of installing GB ROMs.

What was told: Do a full wipe before flashing a rom. With this action the /data partition and ext partition (and some other partitions, but these two are the were apps will be installed) will be formatted. Now apps should not install "themselves". A solution for now:

Manually uninstall the apps which reinstalled themselves.

And you can turn google's automatic backup off . You get the google contacts from syncing with google account (settings>accounts & sync). I also turned off this automatic backup, sync on the described way and i have all my google contacts on my phone. Furthermore, i (would) backup myself with titanium backup + nandroid + sms backup & restore.
