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.

Intuitive guide to Apps2SD?

I knew this time would come....
I've got too many apps on my phone and Im running low on space, and I've noticed my phone has been dragging lately.
I have an 8GB class 6 SD card, so hopefully speed shouldnt be an issue.
I have yet to use A2SD...
If I partition my drive, do I lose everything that's on there? Obviously that's not a problem as I can just move everything over to my computer then copy it back, but if I can leave the data on there and partition that'd be great.
Im having a hard time finding a step by step "from day one" guide.
Mind pointing me in the right direction? The only thing Ive found in the wiki is moving to a new SD card with A2SD.
Im currently running DC 2.07.2

BACK UP SDCARD
Boot into recovery. Partition SD card (default values)
Download http://www.darktremor.com/files/misc/a2sd-2.5-signed.zip
Flash above .zip as any normal ROM
Boot phone
Open command prompt and type:
adb shell
a2sd install
Tada.

Ok great, got that part down.
Now moving the already installed apps over to the SD card? What else do I do from here?
Thank you for the help!

Actually, looks like everything went ok...
ls -l /data reveals all the locations as /system/sd/app
I didn't bother to look at free internal space before installing, but my interanal free storage is now at 130MB. Sound right?
Last question i have for now....
Now that all my apps are on the SD card, if I were to flash a new ROM (say a new ROM Flipz comes out with) that has A2SD support... I dont' have to re-install them as both the apks, odex, and dalvik are all stored on the SD card right?

The only version that I'm aware of that moves Dalvik-cache to the sd card is Apps2SD version 2.5. I don't know if anyone has that in the ROMs yet. Many of them are either using an Apps2SD that was built for Fresh 2.0d, Apps2SD version 2.0, or the Apps2SD which is common in the 1.5 builds.
Your apps in /data/app and /data/app-private are on the sd card. You can flash Apps2SD version 2.5 (A2SD) from http://www.darktremor.com/files/misc/a2sd-2.5-signed.zip if you want to move the dalvik-cache.
EDIT: I really should read the instructions that was posted before I stick my foot in my mouth. The file is the one located at Darktremor, which is the version 2.5...so, yes...your dalvik-cache is on the sd card.

So I tried the above method, but all my apps stopped working and when I go to reinstall them, it says "Insufficient Space for App"...
What did I do wrong?
EDIT: Okay, nevermind, it seems to be working now. I tried installing the app again and it installed fine the second time. Trying another one now.

I did this recently and just found out that I cannot install/download apps from the market, it just gets stuck there. Does it know where its downloading too after a2sd is installed?

[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...

[Q] Question about phone backup

Hi, i am very new here and ilack some of the basic info. so i have couples of questions. thanks very much for your answers.
1. what is the internal memory of the htc hd2? and when you partition your sd to fat32 and ext3, will the internal memory be the sum of the ext3 and the phone internal storage?
2. when you want to flash your hd2 with a new rom. do you need to format both partitions of your sd card (fat32 and ext3)
3. when i tried the latest ultimate droid rom, i saw the author posted the rom and another thing called the layout (3.0.2.4_magldr_150M_partitionLayout_30M_cache). what does this do?
4. how do you make the phone to move or install apps in the ext3. and how do you back up those data and apps in the ext3?
and again, thanks guys for helping me out.

1 internal memory, do you mean what's available after a flash? 260 Meg or so with the small cm7 roms (typhoon for example)
No, the internal memory wont show the sum of internal plus ext BUT it will work as if it is. Say you install a 20meg program, internal mem goes down 20 but back up 20 after a restart.
2 no, when you perform the wipes through cwm it takes care of the ext partition and the .android folder on the fat32 for you.
Some apps may put data on the fat32, in which case you can delete those if you want or if you have isues.
3 the layout (clockworkmod, or cwm) sets up the various partitions on your nand (internal) memory, boot, system,cache,data. Without the layout there would be nowhere for the rom to flash into.
The main point of interest in cwm is the system partition size, big roms need big system partitions, sense roms for ex. need 250meg or more, typhoon needs 130. Flash a big rom to small layout fails, small rom on big layout wasted space.
4 you don't, if the rom says ap2sd enabled or words to that effect, it does it automatically. You can test this by loading up some apps then browsing the SD card on a Linux PC
When you run backups and such, it just does it, the phone has no idea that some of the info is on the SD, it treats it as internal.

i dont understand why is that? so if the rom is apps2sd supported, it will automatically install apps to ext3. then it makes sense to me that the mem goes down, but then why it goes back up???

Example, 250meg internal plus 1gig ext partition.
internal memory shows as 250meg,, install 20 Meg app which goes to ext partition BUT the system displays internal mem as 230, , you reboot the phone and check again and internal memory shows as 250 again.

oh, thanks alot, i get it. but which backup solution is the best? and how does backup using clockworldmod work? does it make a backup file to sd card?

Hi,
It depends what you want to back up.CWM backup will take a snapshot of your entire ROM system,data,settings,everything.A bit like a ghost image of a drive on your PC.
This way, if you install a new ROM and there is a problem,or you don't like it,you can RESTORE your original ROM and everything is back the way it was before.
CWM backup saves to the sd card.
If you just want to backup data,use something like Titanium Backup.

[Q] Apps to EMMC?

So searching thru the threads here it seems that the only way to utilize the EMMC memory on the Nook Color is to repartition the NC so that it all looks like internal phone memory? Is this correct or has there been a way found to utilize both the EMMC memory area AND the SD card?

Not sure what you are asking specifically but you do not have to repartition the Nook to look like internal phone memory to use the internal memory.
1. You can use the internal memory stock or rooted and you can repartition the internal memory so that the system and data allocations are to your preference. Typical partitioning is 1GB system and 5GB data. Plus whatever size SD card you insert.
2. You can install a custom ROM and the use of internal memory is the same as above with the standard being 1/5GB. Plus whatever size SD card you insert.
3. You can run a ROM on a bootable SD card where the ROM sees 1GB of the card as "internal memory" (also some space is used for the system and ROM) and the rest of the space on the card is seen as "SD card external memory." You can also mount the data partition of the Nook's internal memory so that the bootable ROM on the SD card also sees another data partition of 5GB. This is handy for items you want to appear to both the Nook's internal ROM and the ROM on the bootable SD card.

I'm not clear what you are asking either. Before I repartitioned I had 1/5 and ran apps that I worried about load times on from eMMC. Stuff like flashlight or aldiko that I don't sweat that much I loaded from the SD card. Because I felt the 5 was going to waste I flipped it to 5/1. Now I ignore the loss of the 1, load everything I run to the 5 and have 32 to store books, movies, music or whatever on. (Technically I could make use of the 1 if I wanted to but it's not worth it to me.)

I have 5 gig sitting there doing nothing in EMMC partition. I would like to be able to access this memory as well as the external 8 gig card i have in it. Right now the space on the EMMC partition never gets touched.
So will the nook start to auto install to the EMMC partition if I fill up the one gig partition? or is it just going to sit there unused.

Except if you changed something in settings, the original installation place is the EMMC.
In case you fill all this space there, then you will have to start installing apps to SD.
For me there is no reason to install directly to EMMC, except if some app only runs from there and therefore should be installed only there (like widgets).

after the install of CM 7.2 the auto setting places apps in the 1 gig partition and apps2sd moves them to the 8 gig external card. the 5 gig EMMC partition is completely untouched.
If I fill up the 1 gig partition will they move to the EMMC? if not it appears this space will be completely wasted. I would prefer to use it as that frees up space to put music/media files on the SDcard for road trips.
I only leave apps on the internal memory I want to run faster. I noticed with my phone that once that spot start to fill up the phone runs noticeably slower.

No and Yes. Unless you go to Settings>Cyanogemod settings>Application> check Use internal storage
Then you will lose the SD card and gain the 5G. You can easily go back by unchecking it again whenever you want to. (That's why I did what I did with the partition swappy stuff.)

It's there, you can put anything you want in it, the question is whether the apps you use can find the files you've stashed there. Some apps can, some can't.
BeyondPod (RSS feeds) lets you put its storage anywhere you want, so I moved that and my music into /emmc, and Music found the mp3s without me having to tell it anything. I don't buy many mp3s from Amazon, so I don't know how that interacts.
Also, I swap to /emmc, which is still an experiment in progress.

No, it won't do it automatically unless you always use it, like another poster suggested.

To further clarify, once the system partition is full that's it, the only thing else it does is tell you it's full. No rolling over, no starting to install elsewhere.
All Settings>Cyanogemod settings>Application> check Use internal storage does is trick the NC into thinking the internal memory is an SD card. When you have that checked and are loading all your apps to the External memory by choosing Settings>Cyanogemod settings>Application>Install location>External you are loading them to the 5G.
The bad part about it is that you can only use one or the other, if you load a bunch of stuff to the 5G and then switch to the SD card, (uncheck the Use internal storage box), you won't be able to count on the stuff on the 5G to load properly. Same with if you load a bunch of stuff on the SD and change to the 5G.
*I've* chosen to repartition the system partition to 5G and the eMMC to 1G. 5G is so much more that I should ever need for apps it's ridiculous and because I have a 32G SD card I can just forget about the 1G.

I suppose I should repartition but I don't want to have to wipe and reinstall everything.

I waited till I had a genuine Sandisk class 4 16G SD. I know you shouldn't have to worry if you aren't booting from it but what the heck.
Oh and Titanium Backup is your friend. It'll even get your wallpaper back. The only thing I had to manually reload was the custom boot animation.

i tried titanium with my phone and it failed horribly haha. but I will try it again. i would like to have access to that space. also need to try loading my mp3s to it via the PC. that may work as well.

Download the latest Titanium and backup. If possible save the *.apk file to your SD Card.
http://forum.xda-developers.com/showthread.php?t=1094371 Choose the "c" repartition option. After completing the repartition and format you will have a virgin install of whatever ROM you are running. Either install Titanium from the apk or download it again and do a restore, (note the amount of memory you have at the bottom). If I remember right you have to click install and done for every third party app you have but what the heck, it's better than setting there watching pixels burn. Once the restore is done look at the memory stats in Titanium again and note what memory got used. Reboot one last time and you are done.
As for the mp3's, I do all that kind of stuff through Samba. The only time I plug a wire into the NC is to charge it. I guess you could take the SD card out to do that but I've been given to understand we want to avoid taking that in and out where ever possible as well.

Another alternative to above Titanium BU tip is to sync your BU to Dropbox, zip it and after reinstall of ROM upload your zipped BU file into the SD folder Titanium makes when first installed, unzip, overwrite, and everything's there. I've never had trouble with this method. And it's fast...
