[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.
DesireDroid

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] move app+data to external 64g card

Hello,
My device sm p605 rooted by de la vega root method.
I m looking for a method to move my app+data on my external sd card. I tried many methods but no one is working with my device.
I tried:
- link2sd partioning external sd card into 1st partition fat32 + 2nd in ext2: It generates a script with shortcut linking but after reboot when I launch linked app It collapses with message of incompatible device blablabla.
- mount folder: doesnt work and not free
- Directory bind doesn t work?
So if someone succeeded in moving app + data on external card, It would be very helpfull he explain the good method. Thank you.

FolderMount works for me.

Try settings -> General -> Application manager -> (swipe left) SD CARD -> Checkbox any app you with to move.
If it is check marked, it should now on the SD card instead. I know for fact this moves the app itself, but haven't tested to see if it moves the data too. This is the native App2SD introduced in 4.3, hope that helps.

That only moves the app & data to the /sdcard/ partition, which is on internal memory, not on the actual microSD card, which is mounted as /extSDcard/.
Folder Mount works great and is free. I haven't tried to move the APK's folder with it, as I'm pretty sure that would break stuff badly (boot-loops when apps try to launch during startup), but the APK's are usually not that big and you can have tons of apps installed on even the S4 16GB which only gives you 9GB to start with (I have something like 30GB of apps installed on mine). The majority of the data used by apps lives in /android/data/obb/ and /android/data/data/ which you can move. I have ran into boot-loops moving some folders because an app (especially GameLoft ones) try to launch on boot but they launch before FolderMount has a chance to mount folders, so they crash the OS and send you into a boot-loop until you remove the SD card. That's on my Note 10.1 (2014). On my Galaxy S4, I don't have any boot-loops and I'm redirecting more than I am on my Note. You can stop apps from starting on boot using Gemini App Manager or Autorun Manager (can only control up to 10 apps with free version), so that's a good solution for the boot-loop. Not sure why so many folders cause boot-loops on my Note when they don't on my S4, but whatever. Maybe the S4 mounts the SD card and the FolderMounts faster, or it has something to do with the JellyBean's ROM on the S4.
Anyway, use Folder Mount. I don't know of any other valid solutions.

If you have Xposed Framework installed, Boot Manager is the best autorun manager. Simple and to the point.

[Q] Kitkat Rom with SD card fix?

Before anyone answers, no, I am not looking to simply enable write access to the external SDcard!
Q: Is there a Sense 6 based rom (for the M8 of course), that returns pre-Kitkat functionality for the external SDcard?
I hardly have any apps installed, but because I use GPS apps with offline maps, and the numerous e-books (lots of graphic novels) and such I take along to pass time, my internal memory space is already getting close to full. I've already used the supposed SDcard Fix, which does allow me to write to the external SDcard, but the apps still use the internal storage space only. If not a Sense 6 based rom, is there a alternative rom which returns functionality to the external SDcard? Or maybe some way to change or add symbolic links? It's driving me crazy that I purchased a 64GB card just so that I can carry as much as I can with me and not worry about space, yet can't really make any use out of it.
Btw, I'm looking for a Sense 6 based rom because I love the HTC camera app. Much better then the Google camera app imo, and pretty much the only app I have that actually uses the external SDCard.

Nearly all custom Roms are with sd card fix

Then I'll try one of the Sense roms on here for the M8, though I don't see any specifically mention how the external SDcard is handled.

Yea there won't be no real mention, but we have full access to sd card, and if not there is a xposed module which fixes that, but I use renovate 4.0.1 and I can do all things which I was able to do before with the one x too...deleting music , changing direction really all things, so yea the fix is inside

Even apps using the external SDcard like in previous Android versions? That is what I'm looking for. Simply making the external SDcard writable is not enough, because the apps still don't use the external SDcard when they are installed or they download the needed data for the app. For example, I want the GPS map data to install itself and the app to make use of it from the external SDcard. Me being able to move the data does nothing if the app still wont use it.
Hopefully that makes it clear what I'm looking to do, as I've seen plenty of other posts in other similar threads where no seems to understand what the question really is.
I'll look into the Xposed fix, as I already use Xposed.

Aren't you able to select yourself where to save the data? If the app won't allow it because of slower read and write speed for example you can't do anything against it...external sd are often or always slower then the internal which is nearly like a ssd

You are correct. I was expecting some of the apps to use the ext_sd to write the downloaded data automatically, but apparently only a few of my apps do as such, or give the option. My previous Android devices had much smaller internal memory, so the default action for apps was to write the app to the internal, but download data to external. I was expecting the M8 to work the same, but with 32GB of internal memory (I know its less then that after the OS/stock apps), all the apps defaulted to writing everything to the internal memory and do not use the ext_sd at all. Looks like I'll need to use Folder Mount and see if that will solve my problems.

Comparatively few Android devices offer external storage and Google seems to be on a mission to discourage OEMs from implementing it (no Nexus device has it...). So my guess is, that even the guidelines for Android app development are heading the same way. I wonder if the KitKat version of your GPS app just dropped ext-SD support because of the new rules or they made a general decision that it is not worth developing for it because relatively few devices have it.
Because even under KitKat (IF I finally understood the new permissions correctly) that app should be able to create a folder on ext-SD which it can read and write to.
That is how I understand the KitKat permission system: A third party app cannot write to the ext-SD except to a folder it created itself (=owns it).
So if you create a folder in File Manager on ext-SD, drag your maps in there, File Manager owns that folder. The GPS app should still be able to open them (if it lets you browse to it), but cannot change them or save new ones to that folder.
However, if you create that storage location from within the app it should still have full r/w permissions to that location. If the app does not offer that functionality, you're out of luck.
But that's a limitation of the app - not of KitKat.
If you still have an older TiBu backup of your GPS app that allowed you to save to ext-SD, restore it to your Kitkat rom and check if that works.

[Q] Enabling App2SD on 4.4.2 stock ROM

I am slowly running out of internal mem on account of a lot of apps keeping databases on the device itself, and it would help a bit if I could outsource those to the SD-Card via APP2SD.
I am running a rooted 4.4.2 Sony stock rom. I know usually the feature appears as a button when selecting Settings -> App -> $APPNAME, but not for me, Has Sony disabled it on account of assuming 16GB is enough for everyone, or do I need to do some funky stuff like partitioning my SD-Card in some special manner?
So is there a way to enable the native Android App2SD feature? Or some XPosed module to the same effect?

The only way I've found to do it is root and use FolderMount. Granted, you can only do up to 3 apps on the free version, but it's been invaluable in freeing up precious internal storage space.

Without root, I don't believe there's a way.

Best approach for SD card on M9 Marshmallow

Most of us probably know that Android 6 Marshmallow comes with a new feature regarding the SD cards which can be formatted and configured as something very similar to internal memory.
If you haven't read about it, best first to Google the topic.
(I will add a few links later)
From reading about it, it seems to have its own disadvantages (e.g. that sdcard is slower than built-in storage; and some people claim it's not flexible, even claiming that built-in memory becomes not used almost), so this thread is to discuss this feature for use on the M9
I don't have 6.0 yet on my M9, but have been thinking about this (a lot). Coming from the One X+ with 64GB internal, the storage is the only area in which the M9 is a step back for me...
SD card formatted as Internal memory
Known:
- it's encrypted, strictly linked to 1 device. Card not readable on any other device or computer.
Questions
- what does it look like in a file system explorer?
- what is the built-in memory (32GB) mounted as?
- what is the sdcard memory mounted as?
- can the sdcard be written to *without* any restrictions by all 3rd party apps (the kind of restrictions introduced by KitKat, where apps need special permissions and programming to use external storage). (For me this is THE most important benefit)
- after formatting as internal, there is a choice to "move data from built-in memory to sdcard". What does it move? It's been suggested that if this is done, then the default location for new downloaded apps will be the sdcard - is it
I would think it's best to keep all apps & their data on the built-in memory - and use sdcard for (large collections of) pictures, music, movies, documents, e-books, ... all the stuff you don't need to read or write at super high speed, but take tons of space. Basically the way it worked before Google messed up the sdcard in KitKat.

I also found out something interesting to let the rom see sd by titanium backup or solid explorer (I use these two mainly)
if you tap on sdcard in solid it lets you search the sd path which you can reach and set to use, works fine
also in titanium backup (I use sd backups) if you go to menu>preferences>backup folder path and tap on archiviation provider you can use different "methods" to reach your sd, if you use documentProvider it works just as solid explorer, you have the stock file manager and go to sd folder

I find it useful, I have the best card to get, for its storage to performance ratio (SanDisk Extreme PRO 64 GB).
Before formatting as an internal storage source, apps that could store cache and data externally (Spotify, camera)
But with android M, they where not storing externally anymore.
Now I have a device that has 100 Gb of storage internally.
The only minor downfall is that TWRP can not see this storage, it kind of sees its own partition I think, which is only around 25 GB in size. So to transfer ROMs or ZIPs, you have to plug in via usb

Anyone have experience to share with SD card on marshmallow stock ROM. Still haven't made the time to pop mine in and experiment. :-/
Personally I would want to keep the apps + main app data on built-in storage (32GB) (making the best use of that super fast storage) but give apps full access to the SD card.

Apologies.
Talking about backup and restore HTC backup and restore doesn't work for Marshmallow 6.0

So being its encrypted for one phone,there is no way to reverse this and put in another phone. Example...if phone breaks or you upgrade.

Just received a notification for 6.0 update, can't wait to experiment on this new feature... If I understand it correctly, it would be beneficial for me since i've been using extsd to store large application data without moving the app itself...
