Hi guys,
I don't manage to understand what is the deal with types of app2sd.
On my MS i have froyomod installed and i can push "move to sd" in the app manager without creating a ext2 on my sd card.
1st question: where did the applications are being move to when i don't have a ext2 partition?
2nd question: what is the difference between having an ext2 partition or not having it?
Any one????

The native app2sd sends your applications to a DRMed container on the SD card. You do not need any special partition. App authors need to authorize this (to my knowledge) and does not always work super well.
The older style app2ext hack tricks the os into thinking that apps are installed into the phone nand when in fact this is just a link to the ext2/4 partition on the sdcard. This is apparently more reliable and works with every app.
I used both and dont both with apps2ext anymore since froyo. But i use a very small number of apps...i can imagine that for a fully loaded phone this can be very different.
Also, there was a lot of talk recently about RAM, lag, performance, etc when using each version in the CM7 thread. I didn't really pay attention, but it may interest you (last 2 or 3 days).

There are to method to move app to SDcard:
1. app2sd, this is native feature, all 2.2 rom support this method, but not all parts off a app move to sd, there is few thing still store in internal memory, with this method, all the data that can move to sd will store in .android_secure folder.
2. app2ext method. This method you need to create a ext2 partition on your sdcard, add some modules to support move app to ext2, and all app will store in "fake internal" memory!
Thanks a lot for answering my question!

can someone tell me how to install apps into sd card then open them..i found that my legend's internal memory not enough for me..
What ROM are you using? First of all your phone needs to be rooted.. Second.. You need a ROM that supports App2SD (Applications To SD) - Then you can move the apps to sd and install further apps directly to SD
Most ROMS in this forum supports apps2sd
im planning change my ROM right now..im going to use Indigo bean 0.6..
is that support app2sd?
I use this one and i don't see app2sd ! :/
I just flashed with modacos rom with app2sd. But i dont see the app anywhere in the programs list nor does any app ask me which drive it would like to be installed in. I partitioned my sd with Rom Manager too.
yup..im using modaco with a2sd but still cant found any way to install it into sd card..
any idea?
In my opinion Darktremor app2sd is the best way to install app in sd, you can unpack your current rom, add darktremor, and build it again.

errr..can u give me more explanation about this..
honestly im newbie about this..and i haven't partition my sd card
ext2 or 3 partition is a must for all app2sd ROM except CM6 that use app2sd on Fat32
in indigo the app2sd is not available unless you make an ext partition on your sdcard
I just flashed CM6RC3. A few days ago my sd card received errors so I ended up formatting it. While doing this I stumbled upon the SD partition options in rom manager and ra.
So I set them 32mb swap, 512mb ext3, rest fat32 (16gb card).
When I install apps and use App2SD I don't see much of a benefit since the apps are just moved to the fat32 partition. And not all apps support being moved.
Am I correct in these assumptions? Or am I missing something?
Exactly what and how does the ext3 partition do for my android?
You can use alternative Apps2SD and move all your apps to the ext3 partition.
In that case, your widgets can also be moved, and your apps won't be terminated when you mount your phone as USB drive.
should i be using ext3 or 4?
do i need swap at all? i've search and found contradicting posts
My HTC Hero is running low on memory space (I have Apps2sd installed also, but it can't move all apps), so I partitioned my 8G SD card with ROM manager, with 32M swap, 1g ext4 and the rest being FAT32.
After reboot, I still only see 160M of internal memory from settings, which is the original, and about 6.1G on SD card. That means it already took out the 1G, but why I don't see it as internal memory? Is it because of ex4? I tried ex3 too and got the same.
I have backed up the original SD card, but have not copied it back to the partitioned SD card yet. Anything else I need to do in order to see the expanded Internal Memory?
Thanks in advance!

Your sdcard space has nothing to do with internal memory. What you need to do if you want to have more space is 1 or 2 of a few different things: go into root explorer, move apps from /data/app to /system/app; Use Firerat's Custom MTD Partitions
either of those should give you more internal memory.

I read that after partitioning the SD card, apps will be installed into the ext3/4 partition automatically. But that's not the case after I partitioned. Then I found I need to install app2sd+ instead of app2sd. Is that true?
Where do I download app2sd+ ? do I need to flash a different ROM? I am having CM 6.2.0 now.
Thanks!

CM6.2 has native apps2sd. Go to settings>CM settings>Application settings and select "Allow application moving", then select "External" for Isntall location.
Also, you can move apps that don't install or allow swap to the SD via Titanium Backup.
Just be warned that any apps that have widgets lose widget functionality if you move them to the SD.

Does it install ALL apps to SD card? I thought it's the same as App2sd, only moving those apps that specified by the developers as movable. And there are many apps that can't be moved to external.
My understanding is by partitioning the SD card, the EXT2/3/4 part is considered as part of the "internal memory" so that ALL apps will be installed here, thus free the real internal memory and lead to better performance.
The problem is it doesn't work after partitioning and I read that it needs app2sd+ or app2sd EXT to work, and I am having trouble finding them...
Thanks any way.

Not all, but most. Like BrandoKC said, you can move more apps to the sd using Titanium Backup. Don't move anything with a widget you use, or it won't work anymore.

Are you talking about the paid version of Titanium? The free version doesn't have this feature.

CM's built-in Application Management can only move those apps that you can move by app2sd. I don't see such feature on the free Titanium Backup. My 160M internal memory is constantly under 20M of free memory.
I heard all the good things about using partitioned SD card. I have partitioned my card but that alone doesn't seem to work. it seems I also need to install some customized ROM on top of my CM 6.2 so that apps will be automatically installed on SD?
Thanks!
The free version of titanium does have it. I just used it on my fiances phone last weekend.

Hello, I'm hoping someone can answer a few questions I have regarding the format of the SD Card for the Android system. - Apologies if this has already been explained on this forum, I did a search but didn't find anything too useful that answered my questions.
(I have knowledge of the linux file-system and swap drives, just unsure of the benifits of this for android).
Currently using a 16GB SanDisk Class4 SD Card.
I'm aware that you can format the SD Card to use as a swap-drive and for use of ext2 file-system.
While searching for info on this I found the following xda link which simply explains how to do this:
http://forum.xda-developers.com/wiki/SD_card_partitioning
My questions are:
1. What are the benifits of having the ext2 file-system? (Would apps stored on SD Card run faster etc?)
2. Do I need to keep a FAT32 partition (as opposed to just having a swap and ext2 partitions without any FAT partition).
3. Does the swap drive greatly improve performance. And is this worth doing on a Class4 SD Card?
Thanks in advance!
Hi.
at the first I must say swat will decrease SD card life.
i recommond you to create EXT3 or EXT4 partition.
1)one of the benefit of EXT partition is your phone storage will not full and its help your phone performance.
2)yes.of course you should have fat32 partition for eg:music-movies...and other files.
3)yes.swap is a very good.and it helps your phone ram.eg:when you play plants vs zombie at the first screen game will exit because of ram and swap will use like ram and its good for gaming.
Thanks for the reply, much apprecaited.
Are you sure I need a FAT32 partition though? Videos, music etc etc can all be saved to ext2/3/4 on a linux OS so I just assumed I could just do away with FAT32 all together?
Is the following just not the same as using an App2SD app?
"1)one of the benefit of EXT partition is your phone storage will not full and its help your phone performance."
Sorry for being a bit fussy but I'd like to fully understand what the Ext/2/3/4 partition is actually used for. Is it just used purely for storage?
Thanks again!
In a short summary (and assuming you are using a Kernel and ROM supporting the features) ...
- "Swap" on a swap partition has its own own "filesystem". The data structures are actually created by "mkswap" and the partition is not directly accessible by the user. If your phone runs low on physical memory unused parts of the memory will be swapped out into the virtual memory to make room for other apps.
Note that this is no "magically increase your RAM" solution. Once swapping occurs it actually slows down the system as the swapped out memory regions need to be copied back into physical memory, sooner or later. It may only help to run "RAM hungry" applications.
- "SD-Ext" is a, most likely, ext2 formatted partition to where Apps you move to the SD (either by Android or App2SD) will go. This increases the amount of apps you can possibly install, but doesn't resolve the problem that apps having widgets or apps that are started during Android boot-up need to reside in the internal phone memory.
- The /sdcard partition where all your user data is being stored should be kept FAT32 (for the simple reason of making a backup of your data by slapping the card into card reader easier - Windows can't read Linux filesystems by default). Some ROMs will allow you to format /sdcard ext3 or ext4 ... the advantage is that ext3/4 (if the mount options are correctly set) may perform a lot better than FAT32, though your mileage may vary.
Roger? ...or do is something still unclear?
Many thanks B.Jay - I'll hit the thanks button after I post this reply! You cleared up all my questions, but just going back to the FAT32 partition;
I use linux as my main OS, so accessing the EXT format partition wouldn't be a problem; Do you know if all ROMs would work without a FAT32 partition and replace it with EXT2/3/4 partition? If you're unsure I can always find out by formatting and loading a rom.
Thanks again, you've been most helpful!

Linux would, of course, be able to mount a ext partition (even on a SD card put into a card reader).
As for the ROM ... it depends.
The Stock Kernel Modules AddOn of GingerDX introduces ext3 and ext4 modules for the SEMC Stock Kernel, so in theory (I didn't test it!) you should be able to access /sdcard when being formatted ext3/4 - though it could be that you might need to adjust the vold script to properly mount the partition. The modules are mainly for supporting the sd-ext partition for "Apps-to-ext3/4-partition-on-mSD".
There's also alfsamsung's Alfs Kernel which is compatible with GingerDX and some other ROMs. That would be something you could try as well.
Simply look through the ROM threads ... I think MiniCM7 (+nAa's Kernel) should be able to support it, though this could involve some tinkering.
Personally speaking, I only have a ~2GB sd-ext on the SD in my X8 and the rest is a normal FAT32 partition (/sdcard).
yes you need a FAT32 partition.
when you partition your SD card you can move moveable app and games to ext partition.
please dont move app wich they cant move to ext partition.
cause after restart app that you moved to ext will corrupted.
good luck.
Thanks again! I think I'll follow your trend and try the 2GB SD-ext and the rest FAT32.
sd-ext missing!!
hey guys!! I've a small prob, would appreciate some tips. I normally move apps to sd card, if the app is movable by default. if the app is not movable by default, i use this app2sd by droidsail (available in the market) which force moves parts of the app 2 sd card. When I make back ups using xrecovery, i have no problem.
but when I use cwm for back ups, it gives an error saying sd-ext not found and it skips that part of the back up!! so any app I've moved by default or forced moved to sd card doesn't get backed up!! So I presume I have to create a sd-ext partition manually? How do I do it? I do have an sd-ext folder. but its not in sd card. it's in the root. (never had this prob with xrecovery though)
thanks in advance!!

I have tried to Google this issue with little success. What happens is I used to have the Xperia Ray (GB 2.3.4) where apps like ZDBox can detect my Samsung 32GB microSD and moved apps to SD without issue. Now with the SP, it cannot see the ext SD at all (but Cleanup Master still can). Another issue is that SD Tools was able to display the Samsung SD ROM data on the Ray but can't now with the SP. Also, SD Booster used to recommend 2048 for 32GB SD on the Ray, but now saying 512 is optimal? I am so confused. Is it a SP or JB 4.1.2 issue? Both are rooted BTW.
Because the Sp has internal memory mounted as SD card you won't be able to move apps to SD card.
To move apps and data a lot of people use link2sd to move apps to ext SD card and apps like folder mount to move game data/obb files to ext SD card.
Only works if rooted.

The problem is that link2SD din't move the /data/data/x folder to the ext2 Sd partition, then if you have a lot of files there (like music temporal files of Google Music) the benefits are poor.

It will not move it. It will mount it in this point.
Link2SD can move data to other partition. But. You have to had two partitions on sd card. First one in FAT on wich you hold any files (music, movies...) and second on wich you will move app data. With new version you can have on second partition ext2, ext3, or fat filesystem.
You need to have root of course. You can try make only one partition in sdcard, but in this case you have to make ext2 or ext3 partition on SDCard and I really dont know if it work. I didnt see option in link2SD where you can set your data partition so it will try to find second partition on sdcard.
I use 32GB sd card with 16GB with FAT filesystem and 16 in ext3 to move app data there.
To create 2nd partition you need to use PC and a partition creating tool I use easeus maker.
You need to create partition and make it primary,if you use fat32 it will be supported by stock ROM.
Once done put card back in phone start link2sd and it will find new partition and ask how to handle select format that matches yours.
Then you can link all the apps you want apart from system apps.

I usually use AParted to format all my partitions on SD card from my phone.
As I said before, in my phone link2SD din't manage /data/data/x folder on second partition (ext2, ext3, ...), only manage /data/app/x and probably others.
Then if you try to move to ext2 partition (link) any app with a lot of data files stored, alll this files din't point to ext2, will remain in internal memory.
For exmaple:
Try to download Google Music app, link this app to ext2 partition. Now in app make ready a lot of file in offline mode. It will store all this temp song files in /data/data/com.google.andorid.music folder.
Now check in Link2SD and with any filebrowser, you will see that this files are always in internal memory because link2SD din't manage /data/data/x to link it to second partition on external sd.
Sorry I can't help any more as I dont use that app you said. I do use link2sd and have no issues when linking the app to the ext SD card.
Remember you may see info still on data/app but the contents are sym linked.
But if you are sure you have set 2nd partition correct to primary and using fat32( stock supports this)
I can't help you further sorry

I ended up just using Clean Master moving 19 apps to SD. There are many can't be moved but not too bad consider it is far more convenience than Folder Mount. I also removed SD booster which was tested to offer no speed advantage. Next will be battery drain problem. Boy I feel I have spent more time tweaking the android than actually utilizing it.

Now I'll check that once again (I had to buy new SD Card) and you have right. Link2SD move only:
APK File - /data/app/*.apk
Dex files - /data/dalvik-cache/[email protected]*.dex
Libraries - /data/data/*/lib/app_libraries
And other things from /data/data/ stays there. Only libraries are moved from this folder ((
But Its a solution. Just use FolderMount from Google Play It works awesome.
