APPS on SD?

Any ideas how I could get my apps onto my 4gig sd card.
I have read the tutorial but in my clockwords recovery mode, there is no option to partition.
The reason for the partition is for adding my apps to my SD card.
Currently I have tons of apps and allot of them slow my phone down.
Should this be the case? I was advised that the way android works is, it auto closes apps when the speed starts to slow down?

the linux kernal will close apps when it needs to but that has very little to do with where the apps actually reside.
you need to partition your card with rom manager from the market in order to enable apps2sd( not the crappy froyo apps2sd mind)
copy the contents of your card at the moment to your pc. downlaod rom manager from the market, use it to partition your card with 512mb and 32mb swap. then dowload modinstalllocation from the market, this will allow you to chose where you save your apps too. choose 1 internal( ie the 512mb ext 3 partition for apps2sd you made with rom manager). copy all your content back to your sd card. all your apps should now be in your ext3 partition. if you really want to move apps to the actual sd card main partition, choose location 2 phone with modinstallocation but beware that whenever you mount the sd card those apps wont work till its remounted( its wise not to put widgets on the sd card). to check all this info and make sure apps2sd is working correctly you can downlaod quick settings info from the market and it will give you all the info you need on internal and apps2sd storage on your phone.

Many thanks for your reply.
I have just done as you said and then downlaoded aroudn 4 apps equalling around 20mb.
They seem to be on the sd card and internal.
The size of external has gone down by around 15mb and around 5-10mb has goen down on the internal as well?

That is correct. If you are using legacy Apps2SD or Froyo Apps2SD, the Dalvik cache (see here) remains on the internal phone memory.
So, when you install a new application onto SD card, it will consume memory on internal phone memory, though at a lesser rate than if the app was installed on phone memory (in my experience, roughly half the rate).
The only way to "resolve" this is to install legacy Apps2SD+, which also moves the Dalvik cache to SD card.
Personally, I don't do this - what I do is actively manage my applications using Titanium backup. For example, I seldom use certain large apps such as Google Earth, and some games, but I do want to keep them available. So I install them on the phone, and then back them up using Titanium Backup. When storage is low, I will remove them from the phone, but I can bring them back quickly (and without using data) as required.
I don't use legacy Apps2SD+ because I do have several SD cards that I want to be able to swap between quickly.
Regards,
Dave

Dave - many thanks for your comprehensive and useful reply.
What would be the limitation for using Apps2SD+?
From your reply im assuming it would stop me from chaing sd cards?

Essentially yes - you'd need to keep the EXT partition across SD cards in sync, which while not impossible, is more difficult than just copying .android_secure folder from one card to another which I believe should work ok so long as being used in the same phone.
Regards,
Dave

Excellent.
I think im ready to set it all up.
Got two not technical final question for you -
Which rom would you recommend?
I'm currentl with Frost 2.9a however I found Modaco's custom rom to be mroe fruitful with apps/stability.
Which 16gb/32gb sd card would you recommend?
Thanks

I regularly use two 16gb Class 2 Sandisk cards and a 8gb Class 6 Transcend card. To be honest, I've no performance issues with either and my Sandisk cards regular exceed Class 6 minimums. Personally, I see no point paying extra for a large capacity Class 6 or Class 10 card - I may try 720p recording on my Class 6 soon though to see if it improves the framerate, but I doubt there will be much if any difference.

[Q] [How To] Replacing micro SDcard (rooted)

Hello!
I'm running Eclair on my DEFY, it's rooted via z4root.
I currently hold a 2GB microSD card and, as the volume of the apps is getting higher, I wish to upgrade to a 16GB microSD (a SunDisk one).
But I'm wondering if there's more to do then simply copy the apps to a temporary directory on my pc then fill in the new card.
Anyone has yet upgraded?
--- edit: made a deep search on the forum and find out I need a class 6/8 microSD, then I have to format prior to copy up everything that was on the old microSD.
Anything else should I know?
Cheers,
C*

Nothing special to do.
Just copy your actual SD contents on the new one and Go!
I went from the 2GB for a 8GB like this without any tricks...

Class 6/8 is not needed, my 8GB is a Class2 and it work absolutly fine!
For apps the data rate ofthe SD is not really important, 'cause u'll never load large amount off data each time. And SD card are still very very very slow against RAM.
Flash memory have good random access time, that's much important than data rate.
Good data rate are only for large file transfert from/to an other device (PC, etc)
Last thing: by default le SD is not use for app installation on the defy, they use the 2GB internal memory.
You should use some App2Sd for extend this, and it's better to have Android 2.2 then.

Apps in android 2.1 arent stored on the sd card without a mod available on this phone yet.
Instead it is stored on the 2gb internal memory which should be pleanty for lots of apps

Fine, I thought there were some special "needings", I was stuck to the Motorola A1210 that was a bit tricly because of some apps hidden here and there on the microSD.

Actually the major part of the apps is installed on the microSD, I've checked several times and the percentage is so parted:
Apps/Things on the microSD 85%
Apps/Things on the Phone 23%
I'm not using any program to move stuff, but I'm intrigued by App2SD.
So thanks again =)

As said in the previous reply, I can see stuff is stored on the microSD mainly..

No just copy the stuff from you old card to the new one. And as for class 6/8 I'm using a class 4 and its fine

etherea=> dont mix apps installation et apps data
The apps files are installed on the internal memory, but every app can use SD (intern or extern, whatever is present on the phone) for store datas.
Think about GPS software. This kind of soft need 1, 2 or more GB for maps storage.
The apps itself is on the "apps" space on the internal memory and all the maps stuff are on SD (intern or extern)
You can use software like diskusages to see what is where

Apps are not stored on the sd, however some apps data is.

Well thank you both, I still need to read a lot about the phone and aout Android but your answers did clarify a bit =)

Then, I upgraded to a 8GB SanDisk microSD with no problem.
The only minor issue was a duplicate of a couple of non-vital directories and related data, which were wiped out almost in a second.
Everything's working fine and have now much more space to fill in =)
Thanks everyone for the suggestions and hints!

Guys I'm about to replace my micro sd with Kingston 16gb class 4 but, don't laugh , I cant remove the old one. What do i do? There is a red plastic thingy so i guess it holds it, but do i pull it or what ? Sorry for the dump question.

[Q] Internal-External Memory Swap: useful or not?

Hi
I have a Samsung Galaxy W, and you know that this device has such a little memory for apps and games.
I bought a 16 gb class 10 external sd and I was wonder if the memory swap mod could be a really useful operation.
I'm not usual to install lots of applications and games, (I really use only social apps) however sometimes I like to play some heavy-data games. So I need a help: do you suggest me to keep the sd as a default external memory, maybe trying to move the heavier apps in this external space with link2sd and other stuff, or it would be better to make the swap and then make the sd recognized as internal memory?
I read that sometimes the swap operation causes lags and some other stuff, so I need your opinions and suggests.
Thanks in advice

Some custom ROMs automatically swap /sdcard/ with /sdcard/external_sd/
You could try that, it's a great solution IMHO.
Did you try "GL to SD(root)"? Download it from the market... It just mount the external SD as the sdcard, but temporarily. And it also moves game data to external SD.
Sent from my GT-I8150 using XDA on CyanogenMod 9

Also bugs me as well. I just bought 32gb class 10 card and i am using cow bionic 2 rom. But i already changed the vold.fstab folder back to stock. I would be the same not a heavy app storer. If i dont use the app any more i delete it.
But supposedly if you have a class 10 card you should not experience any lag if you have the swap done?? How true this is i dont know

maybe i'll find this useful for heavy data games like generation of chaos or other apps/games that install themselves on the internal storage and not on the sd card, other than that, i seriously don't know what other advantage it can provide

Of course, swapping is a good solution for huge games data storing on external sd and u own a class 10 sd card which is fast enough for swapping. However, this may cause problem when u want to remove sd card as most of the apps are stored on it.
GL to sd is a better solution to me personally. I wrote a similar script instead of using GL to sd. This mounts certain paths to ur external sd card while keeping other important apps such as launcher, theme, widgets, on the internal sd.

Care to explain about the script you wrote. Also whats GL?? I wouldnt use any big games so no point in me swapping. But if any roms i flash to the phone has this done ill not bother changing it back to stock. Also is class 10 not the highest micro sd card you can get??

Yes, class 10 is the fastest writing speed for MicroSD at this moment.
I used script manager to create a script for mounting and give it SU and set it on boot. It is very simple.
Create a new script file and type the following:
(I used the Android folder as example)
Code:
mount -o bind sdcard/external_sd/Android sdcard/Android
This is for gameloft
Code:
mount -o bind sdcard/external_sd/gameloft sdcard/gameloft
After creating these, u need to cut the files in Android or gameloft from internal sdcard and paste them to the new location on external sd. Leave the original folders empty.
Remember to set them "boot" and "su".
enjoy
Edit: if u download any other games that stores its data in Android folder, it will automatically move to ur external sd card as the script has mounted the path to external sd since every boot.

But, in a swap situation, on the Wonder, Apps are not moved to External SD Card........
without swap they are moved to /sdcard/external_sd/.android_secure folder
with swap, moved Apps should be on re-mapped internal SD, so removing SD Card should not have any effect on Apps...
of course App Data should be on External [Removable] SD Card...re-mapped as /sdcard
It seems to me, for game players, Game Loft, etc.....Gl to SD is the ideal solution....****see also EDIT below****
Video for Wonder Here:
****EDIT: Just to say, yewsiong script looks good for gamers, etc.....****

It's pretty useful if you're an avid gamer. Some games usually reach 400mb+. But if not, you could still use it for storing music and videos.

Hi,
I followed the method outlined in your signature (http://latgale.co.uk/?p=70) and now I can see about 15GB (I have a 16GB class 10 SD) available for apps on SD.
However, when I try to move an app to the SD by using App2SD, the app doesn't go to the 15GB partition. How do you do?
Thanks a lot.

Yeah... This is something I haven't found a solution for. Whenever you try to move an app, it goes to the USB Storage. Since we swapped memories, the app will be moved to the 1.7GB memory. For me it'd be great to have everything in the Micro SD card, the 1.7 GB memory is useless to me...

Yeah, that's a real pity! :crying:
I wonder what's the point of doing so, if the memory available for the apps still remains the 1,7GB partition... why swapping partitions then?
Do you have any idea if there is any ROM that lets you install apps in the "bigger partition" (the 14,3 GB according to the example above) or are you aware of any other possible solution?
Thanks.

Yep, that's exactly what I would like to have!
I bought a 16GB card to install many maps and games, but I quickly ran out of memory so I cannot add anymore apps (without removing already installed apps of course).
That's why I would like to use my SD card for apps - if possible of course!
And it's a pity I have 15GB free (for what? Just my music/video/pictures?) and I cannot use this space for apps.
What are the other ways to achieve this you mentioned?
It'd be really helpful!

SD card (too) slow?

Hello,
I compare my results with Antutu benchmark with other I found here and on the Internet.
My overall score is above 5300, but my concern is low read/write speed of my SD card:
(screen in attachement)
I have 32 GB SanDisk Ultra Class 10 with up to 30 MB/s read/write card. I know I wouldnt achieve such speed in practice, but I believe 5.6 MB/s write and 8 MB/s read is far too slow for that card and that phone.
I have second partiotion (for Link2SD) formatted with ext2 (2GB), the rest ("regular") partition is FAT32 (~30GB)
I am using Xperia Ultimate HD 2.0.3, stock kernel (locked BL)
Any suggestions?

the read is slow, im gonna try antutu om my device, but cant install now. It says it dont have memory, but i have over half empty
edit:
What class is that sd-card?

It is class 10 card, 32GB, with up to 30 MB/s read/write (as declared by SanDisk

Yes, up to 30 MB/s. It means max that, but can be any speed lower from it
But Class 10 should be min 10 MB/s. Try formatting your SDcard, then check again.

It installed at least. Heres my results on stock sd card
If you got root try this:
Im not responsible for any harm that may happen, but this should be safe
https://play.google.com/store/apps/details?id=de.mehrmann.sdbooster
Install that app, ir similar
Set it to 1024, apply (best one for me, try your self. Dont go over 8000. 1024, 2048 and 3072 is safe)
Retest your sd card with antutu.
This is what i got on 1024

Great, thank you guys,
I think I will try booth suggestions - card re-format and SD card booster.
What is the option to back up partitions on SD cards?
I mean "second" partition that is not usually visible under windows, as it is second and ext2..
Or backup with TB, copy files to hdd, format and than copy back, and use backup to restore?

try to browse the second partition with WinRAR. It shows everything. If not use EASEUS Partition manager

Are there any published benchmarks for SD cards? I want to buy a 32GB card for use with Link2SD (i.e. apps running directly off the card) as well as for documents/media files, so I want it to be fast.

The best is cwm recovery. X-Part is fine also.
Do backup.
Then just copy fat32 partition on PC.
Now format sd card. (in usb sd card reader)
Repartition it again.
Put data back on fat32 partition. (return card into phone)
Now boot your phone into recovery.
Restore sd-ext.
That's it.
Please, note that sd cards must be formatted with sd card formatter from sd card association and NOT from operating system.
Then use gparted bootable disc to add ext2 partition.
Make sure MiB alignment is on.
Now, performance will be ok.
For sure add higher value in sd booster then default is.

Q. SdCard

So lately my sd card keeos getting removed unexpectedly?... its not getting removed or anything. Will wiping it aka formatting it make it okay again?

I suggest you read this thread. A lot of members have had sdcard issues. Good luck!
http://forum.xda-developers.com/showthread.php?t=2031009
Btw, I have been using a 64GB SanDisk Ultra Class 10 for over 6 months with no issues. All my music, videos, ROMs backups etc are stored on the card. It gets heavy usage.. the biggest common denominator of the thread appears too be that the size of the card is the main issue and not the brand. 32GB cards are having the most problems.

Hard to say when you didn’t tell us what kind of SD card it is, what size, and how long you have had it. You need to give more information.
If it is a 64 GB card, it is because android natively does not support exFAT file systems for storage. Your issue is that the format is not compatible. In this case, flash perseus kernel found in the original android development section. Problem solved.
If it is an SD card of 32 GB or less, the issue is likely that you need to just format it. In this case just find an adapter to plug it into your PC, when the little window pops up asking you what you want to do “open folder to view files etc etc” all that… just close that window. Open some other folder (doesn’t matter which one) and on the left side you will see the drive shown. It will probably show up as F: or something… maybe G: … maybe Z:… who knows… but it will NOT be C:… C is your computer drive, don’t touch that.
Find the storage device on the left side, RIGHT click on it, and select “format”….
UNCHECK the “quick format option”…
For the file system select “FAT32” and for the cluster size select 32kb… (default is 16, but 32 is better and will provide better performance.)
Start the formatting. It will take a while… so go grab some lunch. If that doesn’t solve the issue then I don’t know what to tell you without more information but my guess after that would be that you have had the card for a while and it simply needs to be replaced.
What size card is it, what class, and who makes it?

That's weird my 64GB SanDisk Class10 card, that I have been using for months on my Note 2, is exfat and I haven't had a single issue with it.
My card was exfat right out of the box and that is how I used it. Right out of the box. I have NEVER formatted it.
Edit.
I'm on Tweaked now. Before that Stock Android.

That's weird my 64GB SanDisk Class10 card, that I have been using for months on my Note 2, is exfat and I haven't had a single issue with it.
My card was exfat right out of the box and that is how I used it. Right out of the box. I have NEVER formatted it.
Edit.

I'm using the Stock Kernel.. if I don't my extsdcard doesn't get recognized. I'd have to format it to fat32.. Here is a pic from Terminal to show I'm exfat. Look at the last paragraph.
