[Q] Apps2SD? - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Stock ROM does not accommodate apps2SD. Might anyone know the likelihood of the devs being able to implement it into future ROMS? For that matter, does anyone know why Samsung crippled it?

Foldermount (available in google play) works wonders. I use it WITH link2sd. Link2sd moves the APK files to a second partition on your sd card and foldermount moves entire folders (aka ones that contain huge amounts of data for games etc) to the sd card. I make use of my entire sd card. So far I have about 12gb of stuff (10.90 gb on the main sd partition 830mb on the secondary one that link2sd uses) on there while my "internal sdcard" is nearly empty at 8.88gb free.

Is App2SD necessary for MyTouch?

I installed Cyanogen Rom v4.0.1 and successfully partition sd card with fat32/ext4/swap. Afterward, I realize there are over 300MB in the /data/.
It seems like for normal usage (not excess # of app installed), It doesn't really need to use App2SD and the internal memory should be sufficient space. That should make the phone more stable and speeder since it doesn't depend on the sdcard at all. I dont' plan to install Hero since i won't need the /swap.
What do you think?
going from using no apps to sd to using apps to sd I find that everything seems to run faster for me. Yes i tested it.
That is very interesting. I wonder why app2sd to faster? I mean the sd card IS slower than the internal flash memory.
It's not necessary for Magic/MyTouch3g. It was designed for HTC Dream which has a small amount of storage for apps, Magic does not have that problem.
im running qtek hero rom...how could i disable/remove a2sd?

The easiest way is to fastboot Amon_RA's recovery.img, there is an option in there to create and format the partitions, you just select it with the trackball.

[Q] Galaxy 3 Apps2SD. Data still being saved on the internal memory..

Hey everyone.
I installed a leaked version of Froyo on my Galaxy 3 I5800. I'm using the hack to always install the apps on the memory card. However, only the main apks of the apps are being stored on the memory card. Any application data is still being stored on the internal memory. For example, installing Angry Birds takes 10 MB on the memory card, but also takes about 2 MB on the internal phone memory..
Apps2SD is a huge improvement, but still, if the data's being stored on the internal memory, I'm gonna run out of space some time or the other.
Is there a hack or something to make the phone keep even the data on the memory card? I've heard about Apps2Ext but not sure if that can be installed on my phone and whether it stores the app data on the EXT partition too.
Any ideas?
Android documentation says that even when app. is installed on SD card,
"The .apk file is saved on the external storage, but all private user data, databases, optimized .dex files, and extracted native code are saved on the internal device memory."

May be that's better because program can run faster.. anyway you can solve it by creating of ext2 partition on your SD card and virtualy enlarge internal storage.
But I haven't found any manual how to do it on i5800.
Are there ext2 capabilities in the i5800's Froyo? I'm asking because 2.1 lacks them, much to my dismay. A Linuxish device with a closed file system (rfs) with no tools available (and FAT), erm...

install move to SD first then choose the option Exteral SD.Anything you install from now on will be installed to the SDCARD but aware the widgets and programs that require root doesn't work well in the SDCARD together with home replacement program.Unless of course the app itself support installing to SD.

Yeah, the APK file, that is the main package, is installed on the SD card. However, all the data that the application actually saves are usually on the internal device memory.
I have enabled Move to SD and set the install path to external, but it will still save application data on the phone memory. That is how Android is designed to work

you can extend your internal storage with your SD card, but you need to create ext2 partition on your SD card first and then <i>and this is the problem</i> explain to your i5800 to use this partion on SD card.
I've red many articles about it on HTC / SE phones where this method work. They say that the ROM must be customized, which haven't been done yet with our phone. The problem is, that the good programmers have Desire / or SGS and they do not care about the i5800

And this is where the problem starts: The i5800 cannot handle ext2, at least not with its stock roms. You're stuck with an exotic proprietary file system (rfs) for which no tools are available.

Yes. For that you need to first flash a fugumod kernel. Then you can use Kyrillos' apptosd script from here. You need to use apptosd script v3 if you want your /data/data to be transferred to your SD. But script v3 works good only with class 6 SD card or higher.
Oh yes. You need to convert your data partition to ext4 and create an ext4 partition in SD card also.
ok formating...
seems that i have here a class 4 sd card 8gb... damn it!
I am currently on Kyrillos 6.1. If i create an EXT4 partition in my SD card, via CWM recovery, how can i move the apps which are already installed in my phone memory to that partition? Like if i use Titanium backup, then would moving the apps would go to FAT partition or the newly created EXT4 partition?

First backup your apps using titanuim backup. It will get backed up in SD card. Then copy the backed up apps and the rest of the stuff in your SD card to your PC. Then goto recovery, advanced, partition SD card. Create the required partitions. All data in SD card will be erased. Then in recovery only, wipe data. Then reboot. After that all the apps which you install will goto the ext partition that you created.
Thanks Dhiren!!! I was just wondering whether there was any way to directly move the apps to the EXT4 partition which are already installed on phone memory..I shall try out as you said...

[TUTORIAL] Everything you wanted to know about app2sd, ext3, ext4 partitions!!

I found this post in some other section!!
i am just giving the same information here for my fellow g3 mates!!
Full credit go to neoKushan
here the original thread!! http://forum.xda-developers.com/showthread.php?t=742351
Nows here what we are here for!!! Clear your doubts guys!!!
Ok, so here's the deal, in a very longwinded way that should hopefully explain everything and answer ALL questions.
You have an SD card in your phone and, a bit like normal PC Hard Drives, you can "partition" them (split them into two or more sections of different filesystems). Normally, your SD card is just one big FAT32 partition, which is fine for storing your pics, messages, emails, etc.
Now, other then your Phone's SD card, your phone will have its own internal flash memory (or "NAND") storage. Tradditionally with Android, you could only install applications to this NAND storage, you cannot install them onto your SD card. So if you have an empty 32GB SD card, but only 5Mb of internal phone storage, you still wont be able to install many apps, if any at all.
This was done to protect the apps from things like piracy - it's not easy to access the location where apps are installed on your phone's internal storage (normally impossible without root), so you can't for example buy an app, copy it, refund it, then install it again.
Still, this is no good for those of us who like to install lots and lots of apps, legitimately, as we run out of internal storage very quickly.
So Google came up with a way to install apps to the SD card. A folder is created called something like .android_secure and this stores (I believe) encrypted versions of applications, but there's a few catches:
1) Apps aren't automatically stored here, you have to manually "move" them
2) Not all apps are capable of being moved, in fact most apps aren't, the developer needs to update their app and allow it. Some apps aren't and wont be updated and some developers may not want to allow it for whatever reason.
3) Not all app data is moved, most of it is but some data is left on your phone so many people still run out of internal storage quickly.
4) You can force ALL apps to be moved to this area by default, but it breaks incompatible ones - such as Widgets, which are unable to load due to the SD card not being "prepared".
So that's Froyo's version. Before Froyo existed, some very clever people came up with a thing called "Apps2SD". Remember I said that your SD card normally is one big FAT32 partition? Well, Apps2SD works by having your SD card patitioned into TWO filesystems. A normal FAT32 partition for your usual stuff and a secondary "EXT" partition. EXT is just a filesystem, like FAT32 or NTFS, but it's the filesystem used by Android internally. The SD card is normally FAT32 because it's a "universal" filesystem, that just about any machine will be able to read, whereas EXT filesystems are generally Linux only, but I digress.
EXT has several different versions. The most common one you'll see is ext3. The main difference between ext2 and ext3 is "journaling", which is just a fancy way of saying that should an operation (such as copying, writing or reading) be interrupted unexpectedly (say, by you turning your phone off), then no data should be lost or corrupted. You know how when you turn your phone on, it says "preparing SD card"? It takes a few minutes, but what it's actually doing is checking that the FAT32 partition hasn't been damaged, because FAT does NOT have journaling. If you used a computer back in the Windows 98 days, you may remember that lovely blue "Scandisk" screen that had to run every time you didn't shut your computer down correctly - that's the same thing. But then Windows 2000/XP came along with NTFS, which also has journaling, meaning you had less chance of loosing data. But I digress once more.
So you have your SD card partitioned into EXT and FAT32. Generally it doesn't matter if it's ext3 or ext4, but you don't get any real advantage with ext4 over ext3 in this instance. Apps2SD then runs a special script on your phone which "symbolically links" the folder from your phone's internal storage where your apps are normally stored, to the ext partition on your SD card. A symbolic link is a bit like a shortcut for folders, except it's transparent to the OS: In other words, Android doesn't know that when it's installing it's apps to the internal phone storage, it's actually being stored on the SD card. This effectively boosts your internal phone memory from the previous 5mb that you had in my example above, up to whatever size you made the ext partition on your SD card (often 512Mb or 1Gb, but it depends on how many apps you install).
Plus, because it's "journaled", it doesn't need to be "prepared", meaning it's ready to go as soon as the phone starts - so your widgets and apps work immediately (unlike "forced" Froyo Apps2SD, where widgets disappear).
The catch with Apps2SD is that whatever space the ext partition takes up is taken away from the SD card. So if you have a 4Gb card (with something like 3.5Gb of actual storage) and you make a 512Mb ext partition, your SD card will "shrink" to 3Gb. The space isn't actually lost, it's just being used by the ext partition. If you reformat your card, you'll get it back.
Finally, there's a difference between "Apps2SD" and "Apps2SD+". Remember I said that your apps are stored on a special folder inside your Phone's NAND storage? Well, that was a bit of a lie. It's actually stored in TWO places. There's a second area which is called the Davlik Cache. You don't really need to worry about what this is for (Hint: IT's to do with the Java runetime your phone uses to run apps), all you need to know is that apps use it to store data, which also eats up internal phone memory. Apps2SD+ moves davlik cache to the ext partition on your SD card as well, freeing up even more space. Some people believe that this may come at the cost of performance, as the internal NAND memory should be faster than your SD card (Which is why you also get people arguing over which "class" SD card is better for Apps2SD - the logic being that a faster SD card means less impact from this move), but the truth of the matter is that your applications will be running from your Phone's RAM anyway, so performance isn't really impacted at all. Since most apps are only a few hundred Kb's in size, or a couple of MB at the most, it's a non-issue.
Finally, any recent version of Apps2SD/Apps2SD+ should work with an SD card that is or isn't formatted with an ext partition. It'll check for this partition when your phone first boots and if it's not there, just use internal phone storage.
Having an ext partition WITHOUT Apps2SD+ shouldn't cause any issues, either, so you can format your SD card whenever you're ready.
So in summary:
Apps2SD "fakes" your phone's internal memory and puts it all on a hidden section of your SD card.
Apps2SD+ pushes even more content to the SD card, freeing up even more space on the phone itself.
"Froyo" Apps2SD has various limitations that "old" apps2SD does not, but is much easier to handle as it doesn't involve any kind of "partitioning".
I don't really claim to be an expert but I wrote this and nobody really chimed in to say anything was wrong, so hopefully it applies here.
I'll try to keep an eye on this thread in case anyone has questions.

No it works like apps2sd, but rather than just symlinking /data/app and /dalvik-cache/ it symlinks the whole data partition. so all your apps would be auto symlinked. You will need a custom kernel with init.d support though.

I got this information from the official Link2SD website, this is comparing Native apps2SD to Link2SD. But I don't know how Link2SD compared with Titanium Backup root, DroidSail Super App2SD, adb and so on. If you know which method is safer or more reliable and which method can move more apps, please let me know, thanks.
Comparision of Native apps2sd and Link2SD:
(Native apps2sd
Starting with Android 2.2 (Froyo) Google introduced native apps2SD.
This method moves
* apk file on Android 2.2
* apk + lib files on Android 2.3+
into a secure folder on your SD card in the main FAT partition.
It is the easiest method because it doesn't require you to partition your sdcard and root privilige.
It has some disadvantages though.
First disadvantage is that application files are just stored on the sdcard's main FAT partition.
When you enable USB mass storage to share files with your computer (or otherwise unmounts or removes the external storage), any application installed on the external storage and currently running is killed.
The system effectively becomes unaware of the application until mass storage is disabled and the external storage is remounted on the device.
Besides killing the application and making it unavailable to the user, this can break some types of applications in a more serious way.
So second disadvantage is that not all apps can be moved with native apps2sd method because of above reason.
In order for the application to consistently behave as expected, developer should not allow the application to be installed on the external storage if it uses any of the following features, due to the cited consequences when the external storage is unmounted:
Widgets, Services, Alarm Services, Live Wallpapers, Live Folders, Account Managers, Sync Adapters, Broadcast Receivers listening for "boot completed".
Force move (requires root);
You can force the apps move to SD card with native apps2SD even the application does not support moving as described above.
Link2SD and some other apps can force move apps if you have root priviliges. But, note that this can break some applications, as described above.

Can we mount ext partitions?

Hello all,
Now that we have root on our aesthetically unique device, I believe our next problem is storage space. I don't know about you all, but my aquos crystal has about 4 gb to work with when it comes to apps. Folder mount works well for me, as far as linking the obb files of large apps to the external sd card, but I still have to store a portion of any particular app on the phone's internal storage, which for me is no bueno. There has to be a better way. (For the sarcastic among you, buying another phone is not an option for me.)
Back in the day of Gingerbread, I remember having a whopping 300 mb of app storage to work with. I was able to partition a portion of my external sd to be used as internal storage for the device, solving all my storage woes. It worked so well, that I was sure that I would be able to find a similar method for the aquos crystal.
Now, I see that Link2sd is able to work with ext2, ext3, ext4, and fat32 partitions, so I figured I would attempt to create a ext2 partition on the micro sd to link to my internal storage directory. I used the Partition Wizard mini tool to create a ext2 partition in windows. Unfortunately after starting up Link2sd and selecting the format of my ext partition (ext2), Link2ds gives me an error telling me that the mount script was unable to be created. I've read that if we get this error, we can select ext4, even if we are using a different partition format. This got rid of the error. Mount script was successfully created. Autolink is selected, which should install new apps directly to the new partition. It doesn't, not for me at least.
I've read several guides around the internet dealing with this issue, as well as completely different methods besides Link2sd, and nothing seems to work for me. My goal in this is to supplement the capacity for apps. I would love to find a way to store all the library, devlik, and app files for each app on the external card, rather than having to keep some of each app on internal, and its larger counterparts on external. As you know, apps are constantly updated, and what seems to happen is if you install an app, then link it to the sd card, and the app gets updated in the future, the updated portion will get installed on the internal card, making your 'linked' app kind of pointless. What I'd really like to do is disregard the phone's internal storage altogether and use something like a 64 gb card as the phones internal storage. This may or may not be possible.
I'm not a programmer. I have a very basic understanding of how these things work. When it comes to things like this, I am literally standing on the shoulders of giants, and benefiting from their tenacity and willingness to share the fruits of their labors. Their exploits, and the internet that tells their story, have allowed me to root and modify practically every console and android device I've ever owned. With that being said, thank you to all that have been involved in unraveling the real potential of this device.
So, do any of you fine saints and scholars know of a way to get around the feeble storage capacity of our aquos crystal?
