[poll]Do you want A2SD (apps2sd)?

Figured it would be good to see how much interest there is in it so maybe a dev will see the point of taking it on.....

Whether I personally use enough apps to fill up internal memory or not, A2EXT is a nice option to have and I miss it. I remember in the past, when implented properly, I had apps on ext and when I would install a rom the apps I had on ext would already be waiting for me on first boot rather than having to wait for them to redownload from the market or restore from Titanium. My vote is yes, if a dev is willing to spend some time to bring that feature to us it can only enrich our experience and would be welcome.

while we are wishing
Id prefer a data2ext that also takes none vital system app files and places them on a partition in the sd card, and ability to make the extension around 2 or 4 gigs, for those of us with 32 gig sdcards that can afford the lost space. with dual mount sd card function should never have to worry about removing or mounting the sd card to where its unreadable to the system. thats my vote

I've never really used A2SD even with my G1, however, having all my apps on a fresh install does seem like a nice feature. Personally, the internal memory is more than enough for me.
I guess its more of a nuisance than anything though (regarding installing apps on fresh boots).

Yes.
1) Make easier backups with A2EXT.
2) A2EXT loads faster than the laggy A2FAT.
3) You can always resize the partitions via Gparted.
4) Unlocks the full potential of Android devices.
Anyone who has an argument against A2EXT should stick with the iPhone.

Absolutely A2EXT,Data2EXT is very nice. being able to have all the apps and data ready to go for the same 15-40 apps with data i use on every rom.
depending on which rom im using equals more or less, but that would make things alot faster.
but its still fun individually installing each one.
Ive had this phone for a couple months now and have been doing more reading and research and have just begun to flash all the roms. having a few of them now, it would be nice to have A2EXT,DATA2EXT.
I thank everyone for their hard work and have a great day!! (baby cries gotta run)

sorry for the newbish question, but in Settings->Applications->Manage Applications, what does the "Move to SD Card" option do? Is that only to move the app's data to the SD Card? I've never used it before.

Cyanogen explains it best. A2SD is where you move it to a part of the SD card formatted to EXT format. What Google calls "A2SD" is the result of a symlink-at-best feature that forces a placeholder for each app on the phone's internal memory with the added drawback that (unlike the real A2SD), when mounted to the hard drive, the apps on the Fat partition are unusable.

There was actually a "no" vote? What does it matter to the people who don't want it?

I'm surprised people actually care enough to vote "no." If you don't want A2EXT, let the grown-ups who know how to set it up partition their own SD cards and run the apps off of the EXT partition.

[Q] Swap, ext2/3/4(?) guide?

Ok first off hope everyone had a great holiday (or Christmas, as the case may be )
I have come to realize that alot of my issues may/may not have been caused by factors outside my phone or the rom I was attempting to install and use. I will give myself credit tho in that in all but one case I have managed to follow instructions to a "T" and have not experienced many/any of the issues that others have. Anyways, I got a new wireless router, and also a class 10 SD card. Some of my earlier connectivity issues are very rare now, and camera issues seem to be minimal also (assuming that the issue there was write speed to the card).
So I've really come to like a few of the roms, in particular one I'm liking right now VERY MUCH is MIUI 1.11.9. What a nicely put together package that is. I would really really like to stay with it.
However, it's huge. With that and two apps (Gmail and Facebook), I'm lucky if I have 14 mb left over. Obviously, this causes crashes and reboots left right and center. Camera usage is almost impossible. But, I'm willing to admit, the problem is likely my fault, because I have not done anything to manipulate swap/ext/etc on my sd card. I have the phone, and I have a formatted 16 gb class 10 sd card.
I've looked through 10 pages of threads and to be honest I'm finding it hard to know where to begin. I'm convinced, however, that if I can learn what swap ext/ext2/ext3 do, and how to create/use them..and whatever else, that MIUI and probably a few of the other roms will be amazing for me.
So is someone bored over the holidays here and can help either point me in the right direction of a Guide to do this, or maybe even write a bit about it for me? Assume I know nothing about how to create a swap, an ext, link2sd, any of it. I don't know how to use terminal emulator, modify or execute scripts...but I can learn!!
I realize that I'm asking for info that is probably obtainable by reading numerous other threads..but I can't find anything truly comphrensive..it's too bad threads couldn't be "stickied"...this subject seems crucial to me in order to get some of these roms to run ok. Many of them operate the same way: they take up 100 mb or so, and they don't allow for easy moving of apps to the SD card.
Anyways many thanks in advance if you can help. I'm sure there's a few others who could probably use a refresher in this also.

I'm learning alot about this and hope to update this thread with my own tips for how to do this in the coming days.
That is, if anyone is interested. If so, hit me with a msg.

internal upgrade?
can someone tell me how to upgrade the internal memory because im getting very low in phone memory.. are there any solutions like using the 1GB for the internal memory of my 8GB card?

Well, you cant physically expand the memory but you can virtually via an extended primary partition and an app like link2sd.

Hey acrobat69
I am pretty much the same boat as you. I have tried a bunch of ROMs, and I am still on 6.3 rc3 now.. went back and tweeked after learning some things and this is the least buggy for me at the moment.
I also do not use swap at the moment.. but this is also something that those in the know here on the Xt720 forums have debated.. how useful is it???
I would love to try swap.. or any other tips you might have.. so I at least will be listening.
I would like to get FM radio working on 6.3 rc3 too.. no luck so far.
I have found that when you overclock.. some speeds and Vsel work better in some roms.. or applications.
I saw one fellow who was running 800/48vsel - overall nice and great for battery usage.. but camera would not work at 48vsel.. would crash it .. running several highpower apps like wifi tether and gps at the same time would crash a low vsel set phone..
SO I know there are many factors that you can tune to make a rom work best for you.
James

When I get back to my PC, ill type something up on this for you as well as archer's other thread similar to this Q.

FYI, FM radio works since 6.3.0 RC4. Well at least as much as FM radio "works" on any of the non-stock-based ROMs at the moment-- volume control is difficult/problematic.
I think 6.3.6 is a good choice if you don't mind disabling the hardware button lights. And if it does bother you, I can make a patch that puts the lights back as the were in RC3 (but would disable notification leds).

Ok so to answer a few of the above questions, I'll try to break it up into sections. Ext2/3/4, Swap and basic memory management.
Ext partitions: since our XT's are so low on memory, a fair while back some scripts were created to make it so that when you downloaded an app, it went into your ext partition and not to the internal. Remember that this was when we had 2.1 and Froyo was only a dream. As you know Froyo has the native App2sd function where you can move most of the app's data/function to your SD card via the .androidsecure folder on your card. Since this was not a function on 2.1 we needed a bypass. This was done by creating a EXT partition on your SDCard to bypass/hijack the installation process and "force" the apps to install to the SDCard rather than the meager internal memory. Since the grand old days, we have evolved that function from app2sd to app2ext where now the /cache can be moved over to the partition as well, in addition to apps like Link2sd with one-click UI to do it for you.
This is how to do it.
1 Make sure your ROM supports app2ext-it should be in that ROMs OP.
2 You need to use GParted or Minitool Partition Wizard to create your Ext2/3 partitions (do not create an Ext4 with either of these b/c they won't work correctly, most ROMs don't support it and you can convert it from 2/3 to 4 in MZ's open recovery).
3 You have a 16gb card and are asking what size should I make my partitions. They need to be in this order-FAT/EXT/SWAP from L->R. FAT is what it sounds like. It is your biggest sized one (and make it Primary/Bootable in your partition wizard). Your Ext is going to be up to you on the size. I usually recommend 350-450mb. Anything bigger is really wasted space. In fact, I chorgle to myself when I see people with 1gb Ext partitions b/c your average size app is usually about 7-12mb (with something like Angry Birds at a meaty 18mb). Remember that 1gb=1024mb. 12mb vs 1024mb-see what I am saying here?
4 So now you have your partitions set up. How do you activate it. You flash your ROM and let it settle down. Get ROOT and open a file manager and go to the ROOT. You will see a folder labeled SD-ext. Open this folder and make another folder called App (not Apps-no S) or if you are using Link2sd, you would put a folder called Link2sd (not LinkS2sd-again no S). Reboot and BAM!!!once it boots up, all your apps that you had will be in there and any new ones will be installed there saving you tons of internal space.
I'll cover Swap tomorrow b/c I am tired of typing for now but here is a thread on some unknown types of memory management that you can do on your own.
Sorry for the long post but I wanted to make it as general as possible so that it wasn't too technical.

Woodrube thank you very much for that, indeed very helpful and to the point. Ill hit you with a thanks when back on my laptop.
James: debates nothwithstanding, I can't see how its possible to install one of these Roms and actually use it...and any decent number of apps with stability, without using the extended partition. I have not had any success until I learned how to do this. Therefore, were absolutely not going to debate it, just do it!
To Woodrubes excellent instructions I will add these tips, learned from Mio7's advice and trial and error:
- do any partitioning before you install your new rom, and do it via a card reader inserted into your computer, not by plugging the phone into the computer via usb.
- do not make the second partition fat. In some threads people said it worked however it never works for me. Create the second partition as ext2 , then go to open recovery and convert it to ext3
- use root explorer to create the folder in sd-ext as Woodrube advised. Make sure root explorer is in R/W mode not R/O or you wont be allowed to
- install Link2sd first of any program. It's when you're running link2sd it seems that you can't create the link for certain applications check the market to see if to the downloadable version then uninstall the app from the phone and reinstall it yourself then when you go back into linksd youll be able to create a link. I'm still experimenting with just how much I can rip out of the system and then reinstall myself so as to be able to move over to the sd card. Btw if the rom app manager wont let you uninstall, use the uninstall function in link2sd. It works, even tho it says "Failed" when done.
See the signature at the bottom of my thread that should be all you need to know about whether not the advice in this thread is good because I'm posting from my phone and I'm using voice to text
Next up I'm going to try installing other roms like MIUI or 7.1 to see you what ones this can be used on. I will post my successes and failures in this thread

I think that foldermount is obselete but may be wrong about that.
Link2sd will do the job on user-apps giving you more free data space. Just choose createlink for all of them (except link2sd, of course). It will not touch system apps.
If you are short on system space, not much will work. Need to trim those ROMs.
Beware of gluttonous apps. Prime example is the newer Swype 50-60meg before and languages. You need enough space around to accomplish the linking of it. It then consumes data space for its workings and lots of RAM in addition. My favorite keyboard but had to remove it. Can use their older beta which is perfectly good. This is just one example of fantastic apps that will bring this old phone to its knees.

Need help fixing /datadata in 4.4.3

Hey guys and gals!
Is there any quick fix to increase the size of /datadata, or could it be symlinked to a partition on the SD card?
Here's my issue thus far:
Anytime I've ever installed/flashed 4.2 and up on the Infuse, I get continuous force closes after about 24 hours. I've traced it to the fact that /datadata fills way too fast, and I don't know of any "quick fix" other than formatting the partition in CWM and starting over again.
Any help or info would be greatly appreciated!

My issue here is that I want to utilize as much internal storage as possible before attempting to use SD card space.
I'm running the latest nightly of Carbon 4.4.3, have only about 100 apps total, including the Gapps package (BaNkS full, about 90mb), and I've already uninstalled the "data hog" apps like G+ and Bitstrips.
This has been going on for a long time and has been the #1 reason I've stayed with 4.2 or earlier ROMs.
If I could get help figuring out how to fix this hurdle, it would make KK a lot more usable to me.

I have same issue right off the bat once I leave GB stock for one of the game I was playing.. such a data hog (250-300MB). I end up installing new rom to test then revert back to GB stock to play the game. I don't want to bother with symlink to external sdcard since mine is a class 2. Using it to backup stuff only. Would love to see this issue fixed or easier remedy to do it yourself. I tried JoyOS rom which got nice feature for symlink to sdcard int/ext built in which solved the issue. The rom got some other issues for me to use it and not being work on anymore. Definitely would love to see dev for other rom to add symlink feature.

I think I've found something that works....maybe.
App is on play store and is called "Cache Apps to SD".
So far it seems to be doing what I need it to by moving data from /datadata to my external 4GB SD card.
Why external? Idk... can't be very secure in the case of someone stealing your phone and getting private data from the external SD... but it seems to be doing something good.

Cool.. thanks. Will check it out once I get better SD card for this method.

I only have a class 4 4GB SD card, and it seems to be working so far.
Will post screenshot of current partition amounts shortly.

I would think you could use a half gigabyte card if you wanted to, it's more than the 350mb allocated.
And so far so good, no decrease in speed or smoothness that I can detect yet, and it's slowly moving all the stuff from /datadata to a folder on the SD. :thumbup:

It's straightforward in theory, but setting it up might be a little tough.
First pic shows my setting. I have it set up to use /storage/sdcard1, which is a class 4 4gb card... Nothing fancy and it works really well so far.
Second screen shows any extra settings, which all I have is to hide the notification when it's done starting up.
Fairly simple to use.
You'll notice that it will make a folder on the SD for itself and start putting data into it.

Class 10 is perfectly fine. It won't use the entire 32gb, of course...

So, after a few days of use I realized it's not working as well as I'd hoped.
I got ballsy and decided to reinstall G+.
Big mistake!
I saw /datadata dwindle to a heart breaking 11kb right after install.
Then a SuperSU update took SU away from the app...
Not pleased at this point, but I can't blame the developers.
Sent from my forehead using Jedi mind tricks...

I'm thinking of trying something different:
Symlink /data/data to /data and make it use that partition, then maybe give the 350mb back to /system, allowing more breathing room for Android.
What say you?
Sent from my forehead using Jedi mind tricks...

I think the stuff in /data/data used to be in same place as /data itself since I don't see it in GB stock version. The apps and games I installed wouldn't take over 900MB. 300MB would be a reasonable size for them all and the rest has to be data the app and game generate. This would explained why my memory hog game was able to install w/o out issue but has trouble in new rom when those data got split to it own folder partition.

OK, fresh install of Carbon 6/22...
Typed "df" in terminal and took a screenshot.
Haven't started any real apps yet, but I'll post a screenshot when I do.

There's this:
http://forum.cyanogenmod.com/topic/39718-workaround-for-small-datadata-partition/
This brings the contents of /data/data back into the fold (not it's own partition). I guess it was split originally (not sure when) to avoid lag, but it doesn't really make sense for this phone because it's all on the same internal SD card.
EDIT: There is also the Ext4All app that (supposedly) does this for you:

Link2SD System Busy/Mounting Error Fix

Hey guys....how's everybody! i wan't to begin this thread by saying that I accidentally stumbled on this fix. I've been using Link2SD on my device, the ZTE N95220, or otherwise known as the Boost Mega/Stormer. If your reading this "guide" I take it that at this point you've rooted your phone and have experimented with Link2SD in the past. This in no way is a guide to setup Link2SD and any administartors that think this "guide" would help others in another thread area be my guest and move it. I
STORY: I was having issues with a few apps and decided, since with their latest update now Link2SD has the cool option to choose where your data is moved IE: First partition/second partition etc., and I thought with this new cool feature I'd have a little more power on my phones storage. I'm definitely a gamer and stretch my phone beyond it's capabilities with a Link2Sd/ External2Internal combo. I'm not going to make this about External2Internal, but in case your wondering it's a nice app that I use to expand my internal storage the app switches/or "swaps" the External Sd card with the internal one making your phone "think" lol or operate as if you now have 32 GB as opposed to 4GB. Why you say would mI need this app if I have Link2SD well link 2SD connects to a second partition that you create on your external sd card. External2Internal actually (on my phone) switches the " internal sd card" with my external, in other words my phone has INTERNAL/SDCARD/and EXTERNAL SDCARD with Link2SD you I have something that looks like this INTERNAL/SDCARD/2ND SDCARD PARTITION and EXTERNAL SD. Link 2SD splits my External so that half of it is used as an expanded storage for my phones SDCARD, with EXTERNAL2INTERNAL the switch is made between my SDCARD and EXTERNAL SDCARD,not "in my experience" messing in any way with the 2ND SD CARD PART. Anyway upon doing a factory reset on my phone and Partitioning my external sd card I proceeded to install Link2Sd and was immediately dismayed at the Error Cannot Mount/Busy or something towards that effect. This is the second time I'm dealing with this and my "fix" has worked so this is what I did.
I immediately hit google up looking for Link2SD "like" apps, thinking that maybe something was wrong with the app. I'm intermediate with the technical aspect of phones but I was bought to an app called DS Apps2Sd Pro. The app is a Link2Sd clone although the interface is completely different. In the settings menu it gives you an option to Initialize Link2Sd, i'm not sure if this is meant to work with Link2SD or maybe it has it's own function, which is what i think since it resolved the problem. Just like Link2SD it asks you to choose a partition and an Sdcard, which i did and then your prompet to reboot. WALLLAH!! When i rebooted my phone Link2Sd, which i hadn't uninstalled and thank god I didn;t or I would've never seen that whatever DS Apps2SD Pro did worked. My original Link2Sd was now mounted and you could either keep the app, the DS Apps2SD pro, or uninstall it, the choice is yours. You don't have to remount the Link2SD program itself, whatver DS did mounted the app and fixed the problem. This has worked now a few times on my phone and hopefully it will work on yours. There were a few times when I had to "mount" using DS a few times but eventually when you look at the Link2Sd storage it's mounted. Hopefully this small guide will help you all,since I spent plenty of hours looking for a solution and could not find one with the Link2sd "failed to mount/system busy" problem. Maybe one of you more technically inclined guys/gals could help explain what happened but for now it seems like it worked. If I helped don't forget to click thanks!!
