Two Launchers!

Hello,
The main Google ICS launcher as I noticed uses around 30mb of ram. However, GO launcher uses around 65mb. My question is if I used other launcher as default one (in my case GO launcher), will the main one keep working? I.e., will it be around 95mb of ram used?
Or, when I use one launcher as default one, the other will be inactive?

The amount of RAM the launcher uses is different for each person. For example, my RAM usage by the stock launcher is 47mb, and is usually around that 50mb point. But anyways...
You select one as the default and let it be your launcher. The other one is no longer running. When you reboot your device, GO Launcher would start automatically, and the default launcher would not.

battery lfe 2 launchers

Is battery life reduced when you have 2 launchers. I installed Espier and noticed now that I have 2 launchers battery life has reduced is this normal? I like the way to uninstall apps from espier. I still use TWLauncher and just use Espier to uninstall apps since I did not set a Default launcher I guess both are running simultaneously.

Activate one of the Launchers, then go to Settings > Applications > Running Services, if you see both launcher you're using in there, then yes, both are consuming battery. Normally, you should only see the launcher that is ACTIVE.

I've seen a similar behavior, but in my case is I found that the problem was with the launcher itself, in this case "GO Launcher EX", I've noticed that after a while, it will start consuming CPU (around 3%) even if it is idle, the solution I found is restarting it (the launcher).

Launcher Redraws / Reload

I've tried the V6 supercharger script, nova, and apex. NONE of them eliminate launcher redraws. It's so annoying!
The only launcher that provides a smooth stock experience with no redraws is...the stock launcher. Why? I love the features of the other launchers, especially being able to back up my homescreen. But the redraws kill the experience. Why is it so hard for aftermarket launchers to replicate the experience?

Whaa...

Try adding this to your build.prop. I had the same problem and this little tweak locks the home screen in memory works great for me. Pay attention, that you don't mess something up in your build.prop!!!

I believe Apex has the option to lock the launcher in memory, if not do the build.prop tweak in the post ^ mine.

Try a less intense kernel too.

Wow. My nova launcher rarely redraws. Rarely. And when it does its quick.
let it be.

Laucher reloads and redraws are the results of Androids wonderful memory management. You'll have to find a launcher which locks in the memory, but by doing so, other apps will auto-kill faster than usual.

When I run nova or anything other than stock launcher, system panel shows its process as "perceptible" and using 40mb of ram while stock launcher has a process running too. Essentially I find its running both launchers, being more prone to kicking it out of memory.
Also on 4.0.1 this happened with the stock launcher getting redrawn. On 4.0.4 it seems to be fixed almost completely.

I still don't have perceptible in my sys panel and my nova usually hovers around 42ish and Max around 50. But I did buy the nova prime and set it as default. No sign of the other launcher unless it is system UI which hovers around 25mb.
let it be.

Yeah I'm jealous then. I been messing around tonight and can't get it to stop showing like that.

This is why I freeze/uninstall all launchers except the one I'm using in Titanium backup. Though you shouldn't really have to, because Android should kill off the old launcher process eventually (when it needs more memory for something else) and it shouldn't return unless you manually switch back to that launcher. But I freeze it anyways just to ensure it doesn't interfere with anything. I freeze a lot of other Google/Android services that I don't use too.

I have been using apex launcher since the beginning on my galaxy nexus. However after android 4.2.2 update, I found that redraws have been really frequent and annoying.
The same happens on my nexus 7, especially after using memory hog apps like the "new hangouts" (really, really poorly optimized...)
Indeed apex reloads always, after exiting from hangouts.
Recently I tried also nova launcher (importing all settings from apex, so my configuration is identical), and I have to say that nova has much less redraws with respect to apex (both on galaxy nexus and nexus 7).
For example when rotating the screen from portrait to landscape, I don't experience any visible redraw with nova, while apex was redrawing quite often...
So far so good, I decided to switch to nova, even if I liked apex really much

wetter app caused launcher redraws
I also had frequent launcher redraws on my GN... the issue came with Android 4.2 and got MUCH worse with the recent 4.3 update (i'm on stock rom).
yesterday I removed the widget from wetteronline.com's "wetter app" I had on my homescreen - and surprise! I could not believe it, did not have a SINGLE launcher redraw since then (2 days heavy use) what a relief...
so I still think it is a bad memory management issue in Android, but maybe it is worth trying if one of your apps or widgets is contributing to the problem.

why are ICS launchers painfully slow?

I often get the circling arrow type of refresh notification when trying to open the drawer in launchers like Apex and Nova. I have the latest radio and set my build.prop to keep launcher in memory. I have almost 200 apps. Is there any way to make ameliorate the problem? It "refreshes" way too often and takes way too much time. I've been using Smart Task Bar and even when installing new apps, as far as I can recall, it has never made me wait to show all apps. What do you guys think is the problem here? Would moving apps to SD help? I vaguely recall it makes the startup slower.

You cannot lock the home launcher process in memory via the build.prop like you can with GB in ICS.
Second, I feel like Smart Taskbar is hijacking the launcher process and as such your home launcher is not getting the appropriate priority it needs to stay in memory. Every time you see the app reloading animation that means your launcher has been killed and has reloaded.
You should try V6 Supercharger to reprioritize your home launcher and unfortunately, uninstall Smart Taskbar since if it's using the launcher priority you will always have to deal with a reloading launcher since it'll be killed very often.
On a different device (and possibly Android version) I'm sure Smart Taskbar would be great, but if it's sitting behind all your tasks, all the time, it's using up memory, which is why your launcher keeps getting killed.

Apex launcher has been fine for me, and I'm at around 160 apps now.
"Move to SD" moves the app to the FAT32 portion of the SD card, which would be much slower overall. I'm using SD-ext which still shows as installed to internal, but all the apps are on an sd-ext partition of the SD card (moving to SD would be pointless from there as it's already on the SD just on a faster/leaner ext4 partition). Besides some applications simply do not like being stored/run from a FAT32 partition.

Thanks for the replies. Although when flashing andromo I picked to have supercharger installed, following your advice, I chose to reinstall via directions from the supercharger thread with script manager and the .sh file. Works better now with less refreshing of launcher. Added bonus, global touch responsiveness significantly improved.

Most memory efficient launcher that doesn't redraw?

Hi all,
I've been using the latest XenonHD w/ Air Kernel #580 and for the most part, everything works fine as it should, however there are periods were i get sporadic launcher redraws, the one i use is Apex Pro and have the 'keep in memory' option checked. This hinders my productivity and communication at the hospital because i would need to wait like 10 seconds everytime for the launcher to redraw then i can proceed to opening my medical applications. The main apps i use through the day are Pulse, Spotify, Epocrates, Medscape, Nurse Drug Handbook, Mini-Nurse, Gmail, browser, and etextbooks. Any launcher suggestions I could try where i don't have to deal with these redraws? Thank you

It's a complicated issue. Redraws may be due to memory or the widgets you're using. Try removing some widgets to see if the redraws go away.
Particularly, Blik causes redraws for me but I've learned to live with it because I very much like the widget.

Simply try Holo Launcher (non-HD version), it's the lightest of them. It has an option to keep in memory.
