Chrome OS does not support Android's adoptable storage feature

Project Member Reported by, Dec 21

Issue description

Chrome OS Version: M72
ARC version: N and P
Internal bug: b/64282104

Android has a feature called Adoptable Storage ( ) but currently the feature is not supported on Chrome OS. This bug is for tracking the feature.

Because of the lack of the feature, Chrome OS users cannot install apps to their sdcard. Apps that support downloading their contents for offline use tend to require the feature when changing the download destination to sdcard, and such apps' download feature might not fully work on Chrome OS.

Just to set expectations, we currently don’t have a concrete plan for implementing this. Android’s recommendation (CDD) is to implement adoptable storage in a long-term stable location since accidentally disconnecting them can cause data loss/corruption, but the majority of Chromebooks don’t have such a location unfortunately.

> but the majority of Chromebooks don’t have such a location unfortunately

Is this true? It seems to me that a lot, if not most, chromebooks with limited internal storage (e.g. 32GB) have sdcard slots, and those are exactly the devices where this feature would be most beneficial. Or are you saying that an sdcard slot does not qualify as a "long-term stable location"? If so, I would again disagree, especially with respect to those devices with less internal storage. Adding a large, "permanent" sdcard to provide more storage seems to be precisely how people use those slots. And on some devices, the slots even have a cover, which seems to reinforce such usage.

Correct, and this is what Android CDD says ("[...] within the battery compartment or other protective cover"). Some Chromebooks such as kevin and caroline have a protective cover, but many others don't.
OK, that's what I figured, although that definition could probably be loosened for a chromebook, which unlike an Android phone, is not exclusively about running Android apps. Specifically, what would happen if an adopted card was accidentally popped out of a phone vs. a chromebook? I suspect the consequences would be much less severe on a chromebook, which is probably not actively running apps or accessing the adopted storage most of the time.
Personally, I would gladly take the risk, given the gains. I have only once accidentally dislodged my SD card on my HP Chromebook X2 in my 6 months of owning it, and that was only because I did not insert it all the way before letting go. Even if the card was corrupted and needed a reformat, the apps could be redownloaded from the Play Store. As long as we had a choice in where we installed particular apps, I could just opt to install data-sensitive apps to the onboard storage, and install games to SD.
Yeah, my Chromebook with the SD card during fish, never pops out, or cones out. If I need to transfer files, it's WiFi. Haven't sucked an SD card in quite a while (embedded computing aside). 
I also would love to have this feature on my HP Chromebook x2. 
In my opinion, adoptable storage is the best feature possible to add real value to users of ChromeOS.
I'll buy a chromebook when this feature is added but not before.
FWIW I am also unwilling to buy any chromebook without this feature.
 We really need this feature.  Whoever use adoptable storage know he should not be popping it out.  Android TV even allows you to do this on hard drives. Not they are not portable. But portable or not, if I use this I won't be removing my sd. Even now, I rarely remove the SD card.  Accidental removal with or without a cover is very rare.  I have an XP X2, and I had it fall a few times not once the SD popped out by itself. It's always my own decision to pull out the SD card.

I want to root my android system on my chromebook to see if I can symlink my apps folders. I'd rather have this implemented in chromeos natively.
Also the addition of crostini is making this feature a must.  Linux is files download are eating quite some of my  meager space.  Glad to have crostini but space is an issue if adoptable storage is even just android, it will free up quite a bit.
I think the point is that many people think it should

Marketing for chromebooks does seem a little fishy when Android is promoted on Chromebooks and then when you buy one, you find out that Android can't use the SD card like your phone can. That could be why Pixelbooks and Pixel Slates have large storage options, because they know Android can't use the SD card yet. FYI - I have been using a HP Chromebook X2 since July 2018.
the only reason why i got a chromebook over windows and apple is because i want to see this feature. i have a chromebook with a sd card slot. i plan on getting a shorter sd card adapter(it is meant for raspberry pi but it works) so it does not protrude around the edges of my hybrid chromebook(basically laptop and tablet in one). i tried looking up android tablets to buy but they are so limited in android tablets that they are no longer selling or being supported for android anymore since phones have taken over. if you try looking up an android tablet right now good luck with the choices they have to offer. :(
I bought a Chromebook because of the Android app support. I assumed that Android apps would function as they do on my Android tablet - I'm sure a lot of other people made the same assumption. Very disappointing to find out app's like Netflix can't see the SD card, particularly when the built in memory is so limited on most Chromebooks.

Please, please Google make it a priority to get this fixed.

Installed beta 72.0.3626.49 today and results are overall disappointing. At first, MediaMonkey (after a loooong search) found my music files on my microSD card. My library is over 10,000 songs, so this was not unexpected. However, after trying VLC (which could NOT see the card) and installing MX Video (which could see all of my 52 movies and played a couple of them for me), MediaMonkey reported "No media" even though the card is still listed in the MM library. Interestingly, MM sees the videos, although only offers to play them with an external media player. I think more work needs to be done before this bug is really fixed.

ya I have noticed that on update 72; apps still CANNOT see the SD card for storage. very disappointing.

Some apps can see the storage without a problem. Kodi will let you map the sdcard as a source now. Same with a podcast app I use that will let you also download podcasts to the sdcard. Seems to be because adaptable storage wasn't implemented that apps like Plex and Netflix still can't use the sdcard

What am I supposed to do with this?

Does the presence or absence of Adoptable Storage really matter with regard to apps being able to write to the SD Card? On my Galaxy S7, Samsung has disabled Adoptable Storage yet apps including Play Music, Play Movies and NetFlix are able to download media to the (non-adopted) SD Card.
