Launcher(any) lag fix

[britoso]

As mentioned here and here:
adding "echo ro.HOME_APP_ADJ=1" to /data/local.prop fixes the launcher redraw lag.

Documentation:
http://code.google.com/p/sipdroid/wiki/FAQ

Due to limited memory home screen often takes several seconds to load. Luckily these phones allow root access. Issue the command "echo ro.HOME_APP_ADJ=1 >/data/local.prop" and reboot, to lock home screen in memory.

update:
it does seem to made a difference
Here are the commands: (batch file to do this here,post#5)

1. adb remount
   adb pull /system/build.prop .

2. edit build.prop with a decent text editor and add these two lines a the end
   

   #fix for screen redraw lag
   ro.HOME_APP_ADJ=1

3. adb push build.prop /system/
   adb reboot

you could try

adb shell stop
adb shell setprop ro.HOME_APP_ADJ=1
adb shell start

if it works you just have to add ro.HOME_APP_ADJ=1 to build.prop.

tried:

adb shell stop
adb shell setprop ro.HOME_APP_ADJ 1
adb shell start

My phone hot rebooted after the last command.
After it rebooted I ran

C:\Users\meeee>adb shell getprop ro.HOME_APP_ADJ
4

Since its 4. I guess it did not stick.

Also tried setting it and immediately reading it, did not stick.

C:\Users\meeee>adb shell setprop ro.HOME_APP_ADJ 1

C:\Users\meeee>adb shell getprop ro.HOME_APP_ADJ
4

The setting stuck after putting it in build.prop, time to check if it made any difference...

C:\Users\meeee\Desktop>adb shell getprop ro.HOME_APP_ADJ
1

Don't reboot, try the commands and watch out if your problem got fixed. If it works like that you can add the line to build.prop.

It did it on its own.

Added this cmd to build.prop but see no changes... what lags you talking about btw?

 

[britoso]

For me my home screens were sluggish. There was a delay when I tried to switch desktops.

I made a little bat.file, which adds those 2 lines to your build.prop.

- put "Launcher_lag_fix.bat" in ..Android/tools/
- doubleklick
- and wait till reboot.

No one has posted yet what the command actually does. All it does is tell Android to try to keep the launcher in memory.

Shouldn't affect anything like the scrolling or any response while actually using the launcher, but will fix some lag for when going back home from any other app, as it doesn't have to re-launch the launcher if it was kicked out of memory.

Various options like this exist in some launchers, and I think Cyanogenmod has this option in the settings too. They are not all the same as this command though, so this may work better for some people while the other ways to do it may work better for others.

As per this it locks the 'screen' in memory. (maybe they mean the screen buffer)

Due to limited memory home screen often takes several seconds to load. Luckily these phones allow root access. Issue the command "echo ro.HOME_APP_ADJ=1 >/data/local.prop" and reboot, to lock home screen in memory.

Makes sense as I always have had launcher locked in memory before this and was still having my home screen redraw very slowly when I switched to it.

A good find
Btw just for info there were issues in apps from pre release system dump of arc
However if u r using apps from the retail dump 'they don't lag'

can you specify where is the android/tools mentioned, can it be found in all android phones?

Btw, I have seen ">>" and ">" then "space" /data/local.prop in other websites, while in the sipdroid article, it is exactly
"echo ro.HOME_APP_ADJ=1 >/data/local.prop".

adb comes with the sdk, for my windows machine its at
C:\android-sdk-windows\platform-tools

in unix ">" sends text to a file (deletes whatever was there) and ">>" appends at the end of a file. If you're not familiar its easiest to just add the one line manually at the end of build.prop.

Hey y'all, wondering if anybody can help me with this:

I'm at work and don't have access to ADB. Can I use Root Explorer to copy the file to the sdcard, mount the card on a PC, edit it, and then use Root Explorer to copy it back again? Or will that cause issues with permissions or something?

EDIT: Well it's intellectual now, I nandroided back to my previous ROM due to some other issues. I'd still like to know though.

 

[Dude Random21]

Ya the root explorer thing should work but just to be safe I would nandroid first cause worst case scenario your phone freezes you pull battery boot into recovery restore nandroid. But seriously I don't think it will be a problem.

 

[Dude Random21]

Just out of curiosity I wanted to see if I could do this without a computer at all and turns out all you really need to do is download estrong (or any other root explorer), turn root explorer option on, mount /system and go and edit build.prop through the the built in note editor in estrong. So that might be an alternate solution for you kippswanson.
