need help with apps2sd on Fresh rom

I just installed the latest version of the fresh Rom. The page for the rom says it will automagically use apps2sd If The card is formatted properly. I use the recovery rom (1.52) to format the card, with a 32mb swap and 512mb ext. But, iapps2sd doesn't seem to be working. I have rbooted, and I have also used the recovery Rom to " move apps and dalv to SD", but the apps are still taking up the phones internal memory.
Is there something I'm missing to activate apps2sd, or move the apps over?
Thanks

http://geekfor.me/faq/apps2sd/

I used the link, and got the response that it working. So why then are the apps still taking up the phone memory? Is this the usual response? What happens when it fills up? Is there anything left for me to do?

Everytime you install or run things, internall memeory is still used for data and other items that are not the APK file. What is the memory amount you show as free? A2SD only moves APK's to the SD. Additionally you can move the dalvik-cache there as well, but internal memory still gets used by app data, widget data, etc.. You might have a bunch of widgets storing lots of data.

Sorry to bring up an old thread...
I gotta say that I think there is something wrong with the version of Apps2SD on the Fresh ROM - or something isn't configured correctly.
I get the same issue (as do many others from the digging I have done) - and I KNOW that the programs I have installed aren't using up THAT much memory.
When I switch to any other ROM using A2SD - with all the same programs installed and no changes in the partitioning - I magically have 140 MB free of internal memory.
Any thoughts?

Cripes, so confused about DarkTremor A2SD on CM7

I'm really surprised that there is no documentation on this thing that I can understand. I'm having major issues with CM7 with DT A2SD. Every one of my widgets is broken. I can't tell what's installed to EXT and what's not. If I go into Manage Applications, all of the widget apps are installed to phone. I have next to zero internal space left.
I need to know how I can differentiate what's on internal, what's on Froyo SD, and what's on DT A2SD - As well as how to move them and tell where each app is going.

i honestly wish i knew. this is on my list to do, but i didnt feel like formatting my memory card cause there's so much on it, so i am just hoping gingerbread improved method will give me enough space.
i wish there was a tutorial or wiki for DT A2SD. you prob should just read that whole thread and it is explained there somewhere.

Some quick commands executed from adb shell or even the terminal on the phone can give you some more information:
a2sd check will give you basic diagnostic information from the DT a2sd script - this will reveal what is running where (apps on /sd-ext, data location, etc).
ls -al /data will help you understand what a2sd actually does for you. If a2sd is set up correctly, you should see an entry similar to "app --> /sd-ext/app", which indicates your /data/app directory is symbolically-linked to your /sd-ext partition (the ext-formatted partition on your SD card). This makes Android see /sd-ext/app and /data/app as the exact same thing, and everything within that folder will actually reside on the /sd-ext partition. The same thing applies to the dalvik-cache.
You can find out more about using a2sd via the a2sd help command, which shows an easy-to-understand listing of the various a2sd commands available.

All the documentation is in DarkTremor's thread.
There is no choosing in A2SD. If it's installed - all apps that are shown as "internal" go to EXT partition. But the phone doesn't know it, and you won't see it in OS visually in any place.
You can choose if you're sending your app data and your Dalvik-cache to SD also, that you can do from the Terminal (command line).
I should probably mention that all apps that are installed to SD using stock Froyo method, remain there - and cause a waste of space. So using A2SD you should move ALL your apps to "internal memory" (substituted with EXT partition).

This is a handy link for Darktremor users...

Hmm.. maybe I should had included some more info.
If I use Root Explorer and check my sd-ext folder, it does have apps within, and from install date I can tell they're from my CM7 install (plus I wiped everything including SD-EXT before flashing anyway). The problem is that some of these apps are things I do NOT want on SD-FAT or SD-EXT, I need them on internal (basically anything that I use with widgets, and LauncherPro). Pretty sure having widgets on EXT is what's causing my home screens to **** the bed.
Checked Install Location, right now that's set to Automatic.
If I go to Manage Applications, these apps appear to be on internal (Move to SD card is available on the button). I've read the FB page and original thread, I still see no way to differentiate between Internal, SD-FAT and SD-EXT - or how to move them between with certainty.

/sd-ext is the same as internal for all intents and purposes. You don't choose what apps to run off of /sd-ext, they all do. This is not causing your widget issues.
If you use DT a2sd, "Internal" becomes synonymous with "sd-ext". They are one and the same.
You SHOULD, however, move all of your apps off of SD-FAT - that is the implementation of "apps to sd" that breaks widgets.

Ok, I moved all of my apps off of SD-FAT and back to internal.. seems to be going well so far. The only thing I'm curious about now is that I didn't really get any space back, I still only have 21MB free (cleared browser and market cache as well). I've obviously messed something up somewhere along the line. Any ideas? I'm such a n00b at this apparently.
I really appreciate the help thus far guys!

You shouldn't have. Your space doesn't change as a result of moving apps to SD and back anymore - because they're all either on EXT, or partially on EXT and partially on FAT32.
If you don't have enough space left on internal memory - which can happen, if you have a lot of apps and they use a lot of data - you can move app data to SD and also Dalvik-cache to SD. This is done using command line commands.
One of those is usually enough.
I prefer the Dalvik-cache on SD - it might be a bit slower (never noticed that), but at least system settings (that are stored in /data/data) remain on the phone's internal memory and aren't prone to corruption.

On that note, moving the dalvik-cache is generally a better idea than moving /data/data. Better stability and compatibility and whatnot. Only bother with moving /data/data if you really really need the space.
You can move the dalvik-cache to sd with the a2sd cachesd command in either the terminal or adb shell.

OH MAN THANK YOU! Moved dalvik to SD-EXT and that did it! 120MB free! Time for a downloading spree!

[Q] HELP TY

CM7 can make you install apps on the sd card, how does it differ from app2sd or app2ext? i have been trying to decide if i should partition my new sd card or its not necessary. There must be an advantage to have app2ext right?
Thank you.

CM7 basically allows you to move all applications using Froyo's app2sd mode. Even ones that have disabled it (like live wallpapers and widgets as those won't work when installed that way).
app2sdext works differently as it will install apps directly to an ext partition on your sdcard (that you manually have to set up). This functionality is NOT build into CyanogenMod, but is easily added with a number of different apps/scripts. This will give you a lot more free space on your phone, and all apps can be installed there regardless of whether they have widgets or have services running. Most app2sdext options will also give you the option of moving the dalvik cache to the sdcard which will save you a substantial amount of space on your internal memory.
Basically, if you want a lot of memory intensive apps, your only decent option with a Nexus One is an app2sdext solution. (I have it with a 1GB partition, and I will soon either need to resize it or delete apps... adding app2sdext was the second best thing I ever did to my phone behind installing CyanogenMod on it.)

why didnt i think of that? thank you for your reply... now i should decide whether to do it now or wait till i have reached maybe about a hundred apps. by the way does it have any effect on the speed of the phone if you do that?
I am on cm7 and decided to put cache apps on sd card using ta utility is there any other new apps like that? ta

Can you do this with rooted stock?

I have a class 4 32GB card, and I didn't notice any appreciable difference in speed. I have moved my apps and dalvik cache to the sdcard using DarkTremor's a2sd. I currently have 260 apps installed on my phone, and that is pushing the internal phone space and the 1GB partition I set up for ext. I am about to bug danger-rat for his instructions on how he resized his internal partitions to give the data residing on the phone more space (I will basically shrink the cache partition and I am looking at resizing my ext partition to 1.5GB or 2GB.
I couldn't live without this anymore. I don't know how I went so long without it. It is so nice to just browse the online market and click install on countless apps without worrying about your space.
If you want to try and move the app data (resides in /data/data) to the sdcard, I have heard that it is recommended to have a class 10 card to keep up with speed requirements. I am not sure how many apps support that.

I believe you can. You would have to have a custom recovery. The main thing I am not sure is if it will mount the ext partition. If you have a custom recovery, do a nandroid backup (just in case it doesn't work), flash the zip for DarkTremor, and reboot the phone (the first boot will take longer).

thanks for the reply i think i read on darktremors post class 4 will do for the data2sd. I have class 4 16GB sd card would 1GB good for the ext? ty

It really depends on how much you think you will be installing. I did a 1GB partition on mine, but now that I install most of the Amazon free daily apps, that space is dwindling quickly. I have programs that will resize the partition for me, but most will have to wipe the card and partition it manually. I do have the install location set to automatic, so it allows developers to specify whether they want it in the "internal" (really it is on the sdext partition, but to the phone it is internal) or external using the froyo method. The Angry Bird apps all default to install on the sdcard, so my installed app base is even larger than 1GB.

is it true that cwm sets the partition to ext3 by default? unlike in ra recovery where you still need to convert it? ta

I have heard that it creates it in ext3, but right now, DTa2sd is showing that it is a ext2 partition. I can't figure out how to find out for sure while the card is in the phone. Either way, it is getting mounted as an ext2 partition.

temasek said:

Anyway when u read the ext partition type in android, most likely u will see ext2 if u are using official DT script cuz of the auto syntax it uses.

then it maybe so, this was posted on the darktremor thread
http://forum.xda-developers.com/showthread.php?p=14134665#post14134665

Well, whether or not it is formatted as an ext3 partition, Android is still mounting mine as an ext2 partition.
Code:
mount | grep ext
NOTE: the "|" is called a pipe. On the keyboard it is the shift option on the backslash key "\". I don't know exactly where it is on the stock keyboard, but on swype it is located under the "D" key when the keyboard has the shift key pressed and you access it by longpressing.
To get your sdcard to ext3, you just need to turn on journaling. You can do this through adb while in the recovery (because you need the partition unmounted to do this).
Code:
adb reboot recovery
adb shell
mount system
e2fsk /dev/block/mmcblk0p2
tune2fs -j /dev/block/mmcblk0p2
reboot
Supposedly Android should auto-mount this as ext3 on boot (which you can check with the first command). At that point, I don't think it will matter what a2sd shows. As the writing of the journal (the big thing with ext3, since it helps minimize write errors on a bad shutdown) is done at the OS level, not the a2sd level.

[Q] n00b question: internal SD card - what's safe to delete..??

So, I had my Raider for about a month before rooting and installing the rumraider beta BUT...my internal SD is showing very little free space, and all I can think of is that I used to have a few gb of vids & pics in one of the folder hide apps, and they were stored on the internal SD. All that ever showed in any explorer app was an empty folder, even though that's supposedly where the files were hidden. Anyway, I deleted the folder manually, just to see if 3gb or so would magically free up.. but that didn't happen. There are also a bunch of no longer installed apps' data folders kicking around I'm quite sure.. so the questions are:
(a) what does the format internal SD card option do in the raider's system menu..and will it wipe out anything important to the function of my phone?
(b) is it safe and/or advisable to manually browse & delete unnecessary folders?
(c) if I've already used SD Maid and see no real noticeable difference in free space, are there any other apps which might do a better job?
..I have only a few dozen apps installed since flashing the rumraider rom, but the phones internal storage was pretty full beforehand.. I just assumed that the whole wipe process prior to (and during, if I read the progress right) the flash would clear all that data out. Its got 16gb internal storage in total.. partitioned, true.. but still.. i have almost nothing free. I find that odd.
'lil help? LOL!

+1 using holiraider

your internal sd is only 9.48gb(ish). on that, you can delete anything you want. whether any apps use any of the data in there is dependent on the apps you have installed. there is nothing there that is */required/* for your rom to function correctly
after backing up all your pictures/music/titanium backup files/clockworkmod backups/etc to your computer or all on an external card, you can safely format the internal sd. the system will recreate any files/folders it needs.
personally, i would just back EVERYTHING on the internal sd up to my computer, format the internal sd from the system menu, and if anything doesnt work properly after that, you always have the files handy.

I have a 32gb sd card so i backup the internal to sdcard2 into a ".No Media" folder. I hate duplicating images.. But this way i always have a back up with me since i like to flash roms while im at work (to impatient to wait till im home).

[Q] error: not enough internal memory - but I have 90MB and app is 30MB

Hi Folks,
Executive summary:
I'm trying to install an app that is around 30MB. I have 90MB of internal memory available. It won't download and complains there is not enough memory.
Gory detail:
I have a 32 GB SD card partitioned into 10GB (ext2) and 20 (FAT32) and I use Link2SD to automatically install apps on the ext2 partition. That is working fine.
There is an app in Samsung Apps, issued by the education department, that I need for my son's upcoming spelling bee. The app is around 30MB. When I try to download it, it complains that there is not enough internal memory and that I should delete some files, make space, etc.
Relevant information:
1. There is 90MB available on the internal memory and the app is 30MB.
2. The app should automatically be installed on the SD card anyway, and so not be concerned about the internal memory in the first place.
3. Other, smaller apps from Samsung Apps install without complaint directly onto the SD card.
The figure of 90MB is from Settings > Applications > Manage Applications and also from Link2SD > Settings > Storage Info. Same number.
The phone is rooted and running Gingerbread 2.3.6.
Thanks in advance.

Thanks for getting back to me.
In setting up Link2SD, a new dalvik-cache folder was set up on the 2nd partition on the SD card and the default action for all new apps is to put dalvik-cache files there. There is still the old dalvik-cache folder on /data.
I used Link2SD to clear all the cache folders and got another 10 MB free of internal memory.
Running df in a terminal I get:
/data size-180MB, used-76MB, free-104MB
Which should mean that the 'old' dalvik-cache folder has plenty of room to expand and shouldn't be stopping the installation of a single new app. Again, of course, any new apps should have their dalvik-cache files added to the SD partition anyway, rather than the original one.
Is their something I'm not understanding about the dalvik-cache?
Thanks for the help.

You're right, smply I thought that your dalvik-cache partition was full and it was the reason you couldn't install anything, but it's weird :S :S :S
For this and many other reasons I don't like to use link2sd, I prefer int2ext+ script; safe, simple, fast, doesn't touch the dalvik-cache partition and keep /data in /data place
AFAIK Link2sd don't move "apps" strictly, It link apps to sd-ext partition, so a part of apps are installed in /data (internal memory) and the rest (the heaviest) in your sd-ext partition
It could be helpful

It's normal I suppose due to Read/Write cycles, but it's better (less cycles) than swap partition (reduce your sdcard's life drastically)

Couldn't Install on USB Storage or SD Card
If, while installing your app, its showing "Couldn't Install on USB Storage or SD Card", then I've got just the solution. You could either fix it permanently,temporarily or do a method each time before you install your app.
Permanent Method
1) If your device is running on 2.2.1 or 2.3.6 android version, upgrade it to 3.4.5 ICS or 4.1.1 Jellybean. If the problem is solved then, don't worry, your problem has been permanently fixed.
Temporary Method
1) Backup your SD Card files and format it. Don't worry, it won't affect your partitions. I cannot guarantee you that this thing won't come up again. It may not but there is still a chance.
2) Before installing your apps, Go to Settings>Storage Info>Unmount SD Card. Select this each time before you install anything. Your app will be installed on to your Phone memory. After installing, Go to Settings again and Mount your SD Card. And of course, you could then Link your app to your partition or whatsoever...
I'll recommend Temporary Method 2 as it is would be easy for you if you're a newbie...Hope that this helped...Thanks:highfive:
