[Q] Question about 2.2 App2sd and the App2sd of custom Rom

For the App2sd function of Froyo 2.2, I had set default to install the applications to SD card and all the "Move to SD" button can work. However, I find that some application still use up the internal memory, e.g. 10Mbs application can only move 5Mbs to SD card.
May I know any different between the 2.2 App2sd and that of custom Rom?
Is the App2sd of custom Rom (i.e. the one need to create ext2/3/4 on SD card) can move all the whole application to SD card and will not use up the internal memory?
Thanks!

There are essentially 3 forms of A2SD:
1. Froyo A2SD - moves the application (from /data/app) to the FAT32 partition of the SD card. Does not touch the Dalvik cache (data/dalvik-cache) or the application data (/data/data).
2. Legacy A2SD - moves the application (from /data/app) to an EXT partition of the SD card. Does not touch the Dalvik cache (data/dalvik-cache) or the application data (/data/data).
3. Legacy A2SD+ - moves the application (from /data/app) and the Dalvik cache (data/dalvik-cache) to the EXT partition of the SD card. Does not touch the application data (/data/data).
Options 1 and 2 should be pretty much identical in terms of internal storage usage, and option 3 should save the most space.
Anecdotal evidence suggests that any attempt to move /data/data to SD card causes a lot of instability, which is surprising because I would have thought that the Dalvik cache would have been more problematic.
The long and short of it is that there is no way to stop applications from consuming storage if they use /data/data. A prime example is Google Earth, which still consumes a lot of internal memory regardless of A2SD because of the data in /data/data.
Personally, I use Froyo A2SD, with the fusecompress mod to compress the Dalvik cache in internal memory.

legacy apps2sd that comes native in froyo, just moves the .apk to the sd card, and not all apps can be moved. apps2sd+ that comes with custom roms, creates a parallel file system identical to that of androids but on your sd card, then points your device to the sd card as the install location, this means alot less space is taken up on your device, some install data is sometimes still stored on your device but for example i have over 200 apps on my desire and some of them are quite large, rockplayer/nfs shift/ 5 or 6 gameloft games ect and i still have over 50mb free

Thanks for your reply, I have a clear concept of these two app2sd now

So i just root my unbranded HTC Desire with Android 2.2 (from holland)
I rooted with the unrevoked method. Link here
I wanted to root because i was in need of ROM, only had 15MB left and everything was already on my SD card installed the normal way.
also with the "forced install to sd" method i was still in need of more ROM.
Like in the post above i just want to have 400 apps installed.
So i need a custom rom.
Now i have notes that if i install a custom 2.2 froyo rom i may have difficulties with bluetooth or fm-radio and maby other problems.
I have also heared about htc releasing source codes and now it should be possible to work around or fix those problems i just mentioned.
anyways I am still n00b in this all and doing allot of research for now. I just want to have a rom that would be the same as what i have now(WORKING WITHOUT PROBLEMS AND NO BUGGES) but with the app2sd in it so that i can have 300 apps and still have free memory.
so could somebody tell me what to do? is there already a custom rom out that works perfect, or i should stick with my rom, or what about OpenDesire
Well hope somebody can help me out with some wisdom.
Cheers and thanks in advanced.

nobody can help me out?
is there an custom rom that works with fm radio and bluetooth and camera and all and has the htc sense in it?

or should i figure out to make my own custom rom?

Most custom Sense ROMs are fine.
The "issue" I think you are referring to is that Sense ROMs do not support the Bluetooth HID profile so cannot utilize a Bluetooth keyboard, whereas AOSP ROMs like CyanogenMod do support Bluetooth HID but the FM radio doesn't work.
Having said all that, I'd imagine that 300+ apps is probably an unrealistic target on any ROM due to the data stored in /data/data. It might be possible if the specific apps don't have much of a /data/data requirement, but in general I'd say it was unlikely.

k having that said, i was thinking of buying a 16gb microsdhc class 6 card.
but, well i didn't know about the bluetooth HID , still is it hard to build up my own custom rom?
I mean, getting for example my current rom and modding things. or getting an official rom from htc and modding that?

try different roms and see which one is the best. Defrost, Opendesire, Aurax, or http://forum.xda-developers.com/showthread.php?t=741775
all of them are great but the best depends on your taste and expectatives.

k making a backup now.
I think i go try http://forum.xda-developers.com/showthread.php?t=768703
I have a 4gb microSD card, so i read that to enable a2sd+ i need to repartition the sd card. can this be done from the phone? i got the clockworkmod recovery.
and shall i make it 1GB so i can install more apps? just thinking crazy.
"is this Rom Manager in the android market?"

[Q] Amount of free memory is draining away although I moved everything to SD Card

Hi,
I have rooted froyo 2.2 with App2Sd enabled and always move everything that possible to the Sd card. In spite of that, I have only 20Mb free space left (I use Android System info app). I have 8GB 6class samsung Sd card and did the partitions as said in guides.
how can I have more space to install more apps or I stuck and just have to decide what important and what not ?
Thanks.

what App2SD?
The native Froyo one or the App2SD+?
The native Froyo one does not move the whole app. Just take a look in the app listing and you'll see how much space it occupies on the internal RAM and how much it occupies on the SD card. You also can't move every app, e.g. no widgets.
The App2SD+ moves all apps to the SD-Card, including cache. But even then the more apps you install the less internal memory is available. That's because of a process I don't exactly remember Some apps unpack stuff which gets copied to the internal data partition, and I don't talk about the cache. Don't know for sure, but you should find it with the search.

When I check the app2sd ver. It doesn't shows the. + Symbol so I guess that it is a regular one. Can you give me a link to the plus version?

?? how shall you check the App2SD Version. You either use the + one, by using an EXT2/3 partition and a proper ROM and not moving the apps manually, it gets done automatically, or you use the Froyo one, by moving each app manually to the SD card in the app settings.
To get APPS2SD+ you need a properly set EXT2/3 partition and then flash a ROM supporting it (like Leedroid if you like a Sense ROM, or DeFrost, Opendesire if you like an AOSP ROM), that's it.

What happens to my apps on SD?

I realize this is probably a stupid question but its something I have constantly been wondering. As a new rooter I have been experimenting with a lot of new ROMs and each time i go through and move the big apps to the sd card. Now when I do a full wipe to install a new ROM, those apps get removed from my sd card yea? My sd card seems fuller than it shows and I'm wondering if this is the case or not? Thanks

When you save an app to the sd card, you are caching a portion of the app there so it sort of dual boots the app. It puts less load on the phone's memory this way. It's kinda like caching songs on Google Music Beta for offline playback in this respect. When you flash a new rom the cached app files are deleted from use, but some miscellaneous files may remain. This may be the cause of you seeing that your memory seems bulkier than before and the files can be deleted easily without harm to your phone. Just be sure of what you're deleting before you do so.

DTA2SD & Zep's V6/3G Scripts

Coming from the OG EVO 4G which had only 1GB internal storage, running apps off of the SD card was essential. We had a great tool called Dark Tremor's App2SD (DTA2SD) Basically this let us store all apps on the SD card (even widgets) on the EXT3 or EXT4 partition of our SD card.
Now I know this phone has a lot of internal strorage but I was wondering if this tool could be used in our phones as well?
Also, for those not familiar with Zep's V6 Supercharger script and 3G Speed boost scripts, they were essential tools for the EVO too. Was wondering if running these scripts would have any real benefit for our phones? I personally and too afraid to jack up my phone to try it (too lazy to nadroid and nandroid back if it doesn't work

Didnt you ask this already, about 23 days ago to be exact?
http://forum.xda-developers.com/showthread.php?t=1371401&highlight=supercharger
heres one from the other day, not you though
http://forum.xda-developers.com/showthread.php?t=1401352
search my friend

Ok fine, you got me. I forgot I made that thread. But neither of those discuss DTA2SD. I am having problems with savings apps to my sd card on this phone. Some times the SD scan doesn't pick up all the apps and I have to reboot for apps saved to SD card to show up. Also, i have experienced on a number of occasions that apps saved to the SD card just disappear and have to be reinstalled.
So lets drop the V6 Supercharger talk and talk about DTA2SD. I haven't seen it talked about in these parts.

I gotta ask... on the EVO I understand since it has about 400MB (if you were using AOSP) or 280 MB for sense based ROMs... but for this device you have 1.8GB... do you really need A2SD even though internal memory can load data faster than the SD card and you have plenty of space on the internal memory?
Don't get me wrong. I am really trying to understand if there is any benefit for this on this phone since it has so much space available. I'd understand if it was considered for the future but I see really unlikely filling out 1.8GB with apps...

[Q] Newb Question about: SAMSUNG GALAXY TAB 3 SM-T210R 7.0"

Hello. I bought a SM-T210R for my daughter she burnt through her 8GB pretty fast. I told her to just move her apps to the SD card..... Than I found out you couldn't. I rooted it. I would like to know if there is a good app to use to move the apps. I tried some of the apps on the store app2sd, and a few others. They don't seem to work and suggest you ask Samsung for a new rom.... Any Ideas? I am sure it has been asked before, I was looking through all the threads couldn't seem to locate one. So I am sorry if you are answering this question yet again :cyclops: Thank you in advance.

Hi I know android 4.2.2hasent been officially released for our tablet but a Dev called @mkaymuzik has been porting it works really good and it has move apps to sd card just incase his doesnt help

Since you're already rooted and (I assume) running a custom recovery, there's a somewhat easy solution for this. First, back up everything from the internal memory located at /sdcard, and copy it all over to whatever physical SD card you plan on using - I went with a 64gb. This is probably fastest if you just back up all of /sdcard to the pc, and use some kind of card reader to transfer it over, you'll get much better speed, but you can do this all over MTP with the usb cable if you don't have a reader. Next, reboot into recovery and flash this kernel, which among other things adds support for a storage swap. Clear the cache for good measure, this won't affect any user data. Reboot, and using a terminal emulator or adb shell, run the following command:
Code:
su
setprop persist.customboot.sdcard internal
Reboot once more, and you'll find your physical sdcard is now mounted as /sdcard, while the internal is mounted as /.sdcard (which virtually nothing will use, but that's fine). Any large games you install should put their data in /sdcard/Android/obb, or /sdcard/Android/data, or just random folders on /sdcard, all of which are now your physical card. Once you've finished the swap, you'll want to delete most/all of the files on /.sdcard, since everything there directly uses space in /data/media. Now the only thing that will eat up your internal memory are actual .apk files.
This does have one downside, the storage interface in settings doesn't really know what to think of the mod. It will claim you only have 8gb internal, but then show the free space available on the physical card. If you've got more than 8gb of stuff on the card the bar graph is completely useless, but at least the text does show the correct free amount. I've currently got around 20gb of misc games installed and working great, however if you have any Humble Bundle games keep in mind that these don't use .obb files and the larger ones will quickly eat up your internal space with gigantic .apk files.
You might also want to disable zram once you flash the new kernel. It compresses ram that's not actively being used, effectively giving you more ram at the cost of cpu/battery. I find we have plenty of ram and I'd rather have longer battery life. As root, the command is:
Code:
setprop persist.service.zram 0
You'll need a reboot after running it, of course, but you can enable the sd card swap and disable zram at the same time, rebooting only once.
This is probably the most transparent method, once it's set up you won't need to manually move new apps as you install them, and you don't need to worry about apps that write to random locations on the sdcard.
