Issues with apps to sdcard?? POST HERE ONLY!!!

I was able to install and run apps from the sd card (ext2), but somehow I still uninstall some apps that i don't use frequently. Is there anyway I can remove the apps from the sd card that i uninstalled? I know the fact that they don't occupy that much spaces, but still I'm thirsty for the knowledge on that issue

uuummm you can go to your terminal and
1- su
2- cd /system/sd/app or app-private
3- ls
4- rm "filename you wanna remove" without double quotes
5- Thats it !!!

and because of the "ln -s" command you could also cd /data/data/app .. it all points to the same place now

issues partitioning SD card for moving apps
I am having ALOT of trouble trying to format my 4GB SD card to the fat32/ext2 partitions.
I have tried using partition manager 9, setting the fat32 (2.8GB) as a primary, and also setting the SECOND partition ext2 as a primary (1GB). I also tried using gparted and did the same EXACT partition, size and settings in all the different programs. I also tried a mixture of FAT16/FAT32 and ext2 for all the settings. I then tried using ext2fsx on my mac using the same exact settings as before. No matter what, it doesn't mount /system/sd, it always is mounted to /system/sdcard.
(the below are estimated because I was entering all commands in the terminal on my G1)
I'm suppose to see something similar to the following:
dev/mmcblk0p2 1.2G 9.1M 1.1G 1% /system/sd
I always get something to similar to:
dev/mmcblk0p2 1.2G 9.1M 1.1G 1% /system/sdcard
I always see the fat32 partition but never the ext2. I know that alot of people on this forum seem to be able to do this without issue. I unfortunately have been working it on all day.
Can someone PLEASE help me out? Thanks!!!

have you tried moving the apps to sd? see if you actually move all your apps and look at that line again to see if there is an adjustment in size

Which directory does your mountd.conf and init.rc files specify in it if you open them up? Does it say /system/sd or system/sdcard? I believe tempo had his saying system/sdcard and used different files than the ones in the post by dwang that does basically the same thing. I recall one of them using /system/sdcard in their post and the other doing just /system/sd. Use the same file from the same post and don't mix the 2 up because they are not the same.
I used dwang's instructions and files and got my 2GB card partitioned and working. I have had a problem getting my 8gb card working for some reason but that is another story. It seems my 8gb isn't readable or writeable after I partition the ext2 section although the fat32 is ok. I'm familiar with linux but don't know what I need to do to make that partition writeable when I can't get it to show up at all except in gparted and partition manager under windows. I tried busybox df -h without it showing so no luck there...
Hopefully what I metioned helps you and maybe somebody has an idea why mine didn't work either although I wasn't very specific.

I tried both files and mounting on both /system/sd and /sd neither of which worked . I also tried various programs to partition the sd card. I have no other ideas...

Hi,
This is how it should look.
I use an adb shell through the computer (windows xp).
The drive with 1.5g available is the sd card drive.

Non-market apps on SD card issue
Okay... Getting this to work has sucked horribly for me and after rooting through the other forums that would apply to my issue i've found no solution. I have RC33 JFv1.42 LucidREM mod, with /app, /app-private, and /data all copied to the EXT2 partition of my SD card. I am trying to install the AndroidVNC viewer using the AppsInstaller app, I have AndroidVNC saved onto the root of the FAT32 partition of my SD card. The Appsinstaller sees it but when I go to install the .apk itself it's giving me the following error:
"androidVNC could not be viewed. Free up some space on your phone and try again." Giving me a 'cancel,' and 'manage applications' button under.
The error doesn't make any sense because when I login to my terminal as root and # busybox df -h, the only parts of my system that are full are the usual suspects:
/system
/system/modules
/system/xbin
all of which are full, but they always have been for me, so I'm not sure if the Appsinstaller is trying to use one of those blocks to extract to temporarily or something like that. what am i missing here!?!?

Partial App migration to SD card...possible?
Has anyone tried to move only *some* of the apps to the SD card?
I'm stuck with a class 4 mSD card, so as I understand it, moving the apps en masse to the SD card isn't a recommended option.
But I was wondering if perhaps I might move *some* apps to the SD card...maybe just ones that I don't use often, or aren't particularly complicated, or maybe just ones that seem to run perfectly fine from the card.
Some of the "high performance" apps, or ones with a lot of I/O dependency I'd leave on the phone internal storage.
As it stands right now, I'm at total app saturation. I've uninstalled infrequently used apps and have them backed up for ready restoration anytime/anyplace. I've moved every cache possible. Yet even at 13MB free, the phone still complains I don't have enough room to install the latest build of AndNav2.
Should I even attempt a partial migration? I have no paid apps (and apparently couldn't install any even if I wanted to) so I'd just be moving the *.apk file and maybe the *.odex files? Is that all I need to move and then symlink to?

Bump for day crew.....

I'm using this setup. I use my own bash script to move apps:
Code:
#!/bin/bash
# mvappndata.sh 1.1 by Autarkis
# GPL OpenSource
adb remount
adb shell cp -rp /data/app/$1.apk /system/sd/app/$1.apk
adb shell rm /data/app/$1.apk
adb shell ln -s /system/sd/app/$1.apk /data/app/$1.apk
adb shell cp -rp /data/data/$1 /system/sd/data/$1
adb shell rm -r /data/data/$1
adb shell ln -s /system/sd/data/$1 /data/data/$1
You call it with the application's name without the .apk suffix.
Code:
mvappndata.sh com.mobisystems.msdict.embedded.wireless.pons.ssd
Known Bugs:
* apps moved this way don't show as Installed or Updated in Market, but as Free
* sometimes, when you are running out of memory, it won't be possible to install new apps from market - the downloading process will hang right at the beginning. Making even more room does the trick
I leave all apps that are being started at boot time or once started should run as a service in the internal memory. I move all the big apps (like dictionaries) to the SD. It mostly works, but since many apps are buggy themselves it's difficult to tell where a certain Force Close is coming from.
Cheers from Switzerland,
Autarkis

Ah...precisely what I was looking to do. Thanks....that helps a lot.
I'm guessing I can modify the script to run directly on the phone....it appears you have constructed to move apps while connected to a PC via the USB cable. Is this correct?

Yes on both counts. I also use ls -laS to display installed apps sorted by size.

looping on android, home button & silent not working on 1.42
Hi,
Had a weird experience the other day. Phone was fine (rooted RC33/JF1.41). Got some AK Notepad reminders but was busy with something so I ignored them (but heard the alert go off). A few minutes later, the phone spontaneously rebooted and from that point on just looped on the android screen.
I figured I was due for an upgrade, so I popped out the sdcard and upgraded to JF1.42. The phone did come back to life, but at that point the home button won't work (wasn't a hardware issue as it worked to get me to the home+power loader) and when I held down power to shut down, I got only the "power off phone" option but no "silent mode" option. Very strange. This was obviously no good, so I went back to 1.41.
Long story short, the phone still looped, so I took this as a sign that a wipe was unavoidable (I didn't have a recent nandroid backup), but since I had WAY too many apps I never used (~200) and my phone was getting unstable (things were constantly force-quitting), I figured I may as well do some spring cleaning and start fresh.
I learned my lesson and finally got the important apps reinstalled and the phone reconfigured the way I want it -- and then did a nandroid backup so I can avoid this in the future.
But what the heck happened that made the buttons not work? That one freaked me out a bit...
And of course I still wonder what caused me to loop in the first place, totally randomly and spontaneously. Are there specific things that can cause that and if it happens again, is there an easy way to fix it?
Thanks

Gah! This is driving me nuts! I absolutely can't make this work.
I can transfer the whole /data/app and /data/data directories to /system/sd, but as I have a class 4 SD card, I get tons of force closes on apps.
So then I try just moving single apps. For example, moving the OI Flashlight app to the sd card.
Code:
# busybox -a /data/app/org.openintents.flashlight.apk /system/sd/app
# rm -r /data/app/org.openintents.flashlight.apk
# ln -s /system/sd/app/org.openintents.flashlight.apk /data/app/org.openintents.flashlight.apk
I do the same thing with the appropriate data directory for the app. I check and the files are moved. The symlinks are present.
But when I try to run the app, it just tells me that the application is not installed on my phone!
Grr! Then if I delete the symlinks and cp the files back to their original locations, same result. I end up having to re-install from backup.
Very frustrating. Any advice?

I don't know what busybox -a does.
It probably shoud say "cp -rp" instead.
It's important that you preserve access rights.
It's also very important that /system/sd is an ext2 partition. vfat won't do.
My script also assumes that as a preparation, /system/sd/app and /system/sd/data have been created. Like that:
Code:
mkdir /system/sd/app
mkdir /system/sd/data
I assumed that was self-explanatory, but it probably wasn't.

unionfs works for this:
have cake and eat it micro-howto:
(Use a recent jf dist)
/system/bin/insmod /system/modules/2.6.25-01843-gfea26b0/kernel/fs/ext2/ext2.ko /system/modules/2.6.25-01843-gfea26b0/kernel/fs/unionfs/unionfs.ko
(partition sd card as described in the aps-on-sd howto)
(mount to /data/local/ext for this example)
mkdir /data/local/ext/app
busybox mount -v -t unionfs -o dirs=/data/local/ext/app=rw:/data/app=ro unionfs /data/app
This has been tested; downloaded apps go to sd card but the system sees apps in /data as well.
The only issue with this is you can't umount the unionfs mount. In theory, you can have writes go to the real /data/app with:
busybox mount -o remount,dirs=/data/local/ext/app=ro:/data/app=rw /data/app
But I have not tested this.

Hi all,
I have moved apps to Sd Card.. I have moved cache to sd card and when all is said and done I had 47mb of 74mb free.. YES... but wait..
Now in using my phone I keep losing free space I am now at 45 of 74mb free. How can I found out what is taking my free space up .?

How to check app to sd???

go to terminal and:
df
see if your /system/sd/ device is being used. Did you make all the symlinks?

mine is being used but also the phone memory is decreasing also. help?

thx i think im not sure...checked out that i have my app to sd thx

I'm having the same problem. I did all the steps on this tutorial from maximus but when I d/l an app my intermal memory decreases and my sd memory remains the same. I went to terminal and wrote df and I don't know what to look for lol I did see system/sd or something like that though. But I'm not sure what that means. Sorry for being such a noob, I'm new to this

Same prob here fellas....
I followed the instructions for the Hyk apps to sd wiki tutorial.
when I check my sd card, it shows the apps
cd /system/sd/app
ls
and I can see that the /system/sd has 25MB used which sounds ok but at the same time, I only have 35MB left on the phone, it was 48 yesterday and all I've done is install apk files via my computer using adb install command.
Why is my internal memory going down and how can i fix it.

To answer my own question.
I think we also need to move dalvik-cache... though not really that important, it's nice to keep the 70-71mb free.
I moved the cache and it went from 35MB to 70MB free.

Keep in mind that moving your apps to sd does not move your cache for default programs. I noticed my memory dropping and realized that it was my browser, maps, market, etc cache. I followed some tutorials on here to move those and my memory hasn't been dropping anymore!

there are three directories that get increased when u install an app
/data/app - stores the apk file
/data/data - stores cache and databases that the app uses
/data/dalvik- app cache used by the system
if u move only one of the above directories ur internal space will still decline

su
cd /data
ls -l
this way you can see if its linked correctly- should show the app folders linked...

Missing Phone Memory after JF1.5

So I rooted my phone and installed JF1.5 last night. As of right now I have no plans to move anything over to the SD card as I am still learning, but for some reason I am missing phone memory.
I have the same apps installed as before I rooted and I am at 23MB where I was at ~40MB before I rooted the phone on RC33.
Can anyone point me in the right direction? I tried searching and came across with a solution, but that seems to be if you are moving stuff to the SD card. I tried to run the commands:
Code:
cp -a /data/dalvik-cache /system/sd/dalvik-cache
rm -r /data/dalvik-cache
ln -s /system/sd/dalvik-cache /data/dalvik-cache
reboot
And I get an error after the cp about /system/sd/dalvik-cache being 'read-only'.
Your help is greatly appreciated.

Those steps will only work if you have apps to sd. Do not try to do that without it, you'll mess up your phone. As for the greater amount of space being used, did you do a wipe when upgrading to JF1.5? If not it carries over all data to the new ROM so if you used the browser at all, the cache for it is usually fairly large and could account for a lot of that missing space. Try clearing that(in browser press menu->settings->clear cache)?

I have the same problem, and came accross the same solution to find out its only for people that have apps2sd... the help would definitely be appreciated

It sounds like its an additional cache for something. Try the following:
Restart your phone - did that work?
Go into app management and clear the data for the android market app.
It's possible there's another 1.5 app that causing cache to build up, but almost rest assured it's cache and probably market cache if you just redownloaded all your apps from there.

If all else fails(and I mean ALL else) you can try these commands:
su
busybox rm -rf /data/data/*
busybox rm -rf /data/dalvik-cache/*
reboot
but leave that as an absolute last resort. If you mess up even 1 character in that, you can really mess up your phone.

should be:
su
busybox cp -a /data/dalvik-cache /system/sd/
rm -rf /data/dalvik-cache
ln -s /system/sd/dalvik-cache /data/dalvik-cache
reboot

double post. sorry.

Okay I am just going to re-install JF and start from scratch to see if I can clear some of this memory up.
Just want to make sure - I do alt+w, THEN alt+s to wipe and then reload JF1.5?

Sorry to double post, but I just did a fresh install of JF1.5 preluded by a wipe (alt+w) at the bootloader screen.
The JF1.5 build starts out with 52MB of Available Space. This seems to be pretty low based on what I can remember from the regular updates. Can anyone shed some light or am I just better off doing cache/apps2SD to clear up some room?

Wow I was just wondering if I was the only one....I currently have available 24Mb nd I used the commands that is located at the H wiki web site....which worked well to bring back my application which were located in my Ext2 partition....I recently wiped my cache from the market like u guys said it nd it wiped around 5 -10 mb from my avalable (had 14 mb)...so now I am wondering is it the Cache from the phone dat is taking all the available space on my phone (which I think its pretty impossible)

Okay so I have half of my apps installed and I am down to 31MB already.
I am going to move something to the SD Card -- which is the easiest and least risky to move to the SD Card? It seems like the dalvik cache is the biggest and clears up the most space. Can anyone point me in the direction of a tutorial for this or any cache to SD? Thanks.

Sure, look in my sig.

Official way to make sure everything is correct?

I'm just curious, i'm pretty sure everything went well for me as for apps2sd... but i was wondering what is the 100% official no bs way to know if you have all your apps on your sd card along with the cache and it's no longer on your internal memory? i mean i only have 33 apps installed but i only have 67mb free on internal memory... i cleared my browser cache along with my market cache and only have 67mb free... any idea anyone?
i just cleared my faebook cache in app management and it jumped to 69mb free. so i'm taking it that my apps are on my sd card but my cache isnt? how do i go about doing this without messing everything up? any idea anyone please?
i forgot to mention...
8GB SDHC SanDisk Ultra Class 6
Rooted JF v1.5
33 Apps 69MB Free
Overclocked @ 528Mhz (Max) 384Mhz (Min)
AppsToSd (At least i think lol)

Well if you want to make sure the sym links are there, the best way i know is to connect the phone to your pc
adb remount
adb shell
cd /data/app
cd ..
ls
if you end up in /system/sd directory then you know its a sym link.

on another note as for the free space, the cache is held in the /data/data directory. I have the below folders moved to sd and have prob around 70+ apps installed and have 73 meg free. FYI also i remember reading somewhere that when you move folders off to the sd partition, nand does not back them up because nand does a bit for bit read of the flash chip on the phone and since that data is no longer on the flash it isnt backed up. Just something to think about if you want this info backed up.
/data/app
/data/app-private
/data/dalvik-cache
/data/data

Furthermore, if you move your cache to sd, put a symlink in and clear cache afterwards it will delete that symlink. You don't need to clear your caches after moving them, you should do it before they are moved.
Good luck.

just type
su
ls -l data
if you see app -> /system/sd/app
then you know you linked up correctly
same would go for any other linked directory
app-private -> /system/sd/app-private
dalvik-cache -> /system/sd/dalvik-cache
etc.

i think i messed everything up now... lol i followed somebodies instructions and all my apps werent working anymore, so i go to install them again but the market says they're installed already, so i uninstalled and tried to reinstall n now everytime it downloads and tries to reinstall my phone reboots... argh i didn't think it was gonna be soo complicated to get apps and cache working off of my sdcard.

There is a space between cd and ..
Cd<space>..
Sym link means symbolic links. Think of it as a shortcut that exists inside the folder. so when you type in cd /data/app u r accually going into /system/sd/data

that is the files and folders in that directory, think of it as the same as doing a "dir" command in windows. But from the output you got /data/app is setup correctly to go to the sd card.

Ok.. I hate to tell you this but... may be you're better off just do it all over again.
Wipe, install clean copy of JF 1.5, wipe again, run apps2sd application by MarcussMaximus, delete cache folders on SD and then move your caches to sd manually from terminal emulator
I found a really good set of directions here
Make sure you understand though how it's done before attempting.
And the best way to tell is to note how much free space is on your phone after clean install, after moving everything and after using your phone for a few days.
Good luck.

Terminal emulator.
su
cd /data/app
pwd
It should say /system/sd/app

i pretty much did, i used the lucidrem jf 1.5 and it went soo smoothly, im running about 50+ apps and got 73mb of internal memory free, and i checked that site u linked in ur post, thats a great tutorial site on moving certain cache.

Problem moving app-private and dalvik to sd

This has been going on for a while and has been a problem through 4 different versions. Every time I move the app-private to the sd card my gf's phone goes into a boot loop. The apps will transfer fine and work just fine, when I transfer the app-private for them it might work for a few days but then boot loop. I have tried lucid mod jfrc33, haykuro 1.5hrv3, jf1.5, and lucid mod jf1.5. The only ones that worked for a day or so are the lucid mod versions. It has stumped me and i have searched and no one seems to have the same issue.
I have tried different sd cards as well to rule that out and I get the same result, by the way all have been partitioned and formated using paragon partition manager. I am starting to think she might have a bad phone from the get go.
Hopefully somebody has some advice on what might fix this problem thanks in advance.
Note: I managed to get the dalvik successfully on the sd card. So the only thing not working is the app-private, causes the phone to boot loop

Try just moving app, app-private and dalvik-cache. That gives you around ~70Mb of free space which is plenty. I've had nothing but problems when I move data. I just don't do it out of principle now.
Give it a shot, if it leaves you with a stable phone, run with it.

Sorry I was not clear about what data I moved. If I move the app-private folder to the sd card I get the boot loop. I have not moved the data/data over because I have read it's not stable for most.

/data/data is definitely bad news. It worked for a day for me, but that's it.
It looks like /data/app-private is starting to mess up now as well. I've been having issues w/ /data/app-private all day. It looks like I'll be leaving /app-private and /data on the phone, and only moving /app.

What commands do u use to set app-private. I had no issue with the commands below
cp -a /data/app-private /system/sd
rm -r /data/app-private
ln -s /system/sd/app-private /data/app-private
reboot
Also is the ext2 partition the 2nd partition.

Yeah I have used that one in abd and it just won't take on this phone. I t is so weird how dalvik works but not app-private. Maybe I should get an rma for it, any issues with sending back a rooted phone?

what do you see when you type adb shell ls -l /data
