Launchbox & scoped storage

Hi guys,

Recently the youtuber ETA prime released a video where he showcased the new Launchbox for android. In the video he gets access to his sd card to import his games/roms seemingly sidestepping the scoped storage issue plaguing android 11 users. Excited to finally get to free up some space on my Galaxy tab S6's (running android 11) internal memory I downloaded the free version of launchbox. However, when trying to import my games from an USB drive connected via an usb hub to the tablet I don't get the option to select the USB drive in the dialogue box "Select folder".

So i'm wondering if this feature is something reserved for only the premium version or is it something i'm doing wrong?

Hi @ehssan, we are seeing some unfortunate issues where LaunchBox is not allowed to write to SD cards due to the scoped storage issues (thanks for nothing, Google). But as of yet, I have not seen an issue where LaunchBox can't read from external storage on Android 11. However, we've been primarily testing with SD cards, of course; we have tested with USB drives, but definitely not with that specific device.

So first off, if you have an SD card slot, I would try seeing if that works.

I also cannot get LB to see my external SDcard where I have ROMS.  The SD card is being read through a dongle.  I also tried with a USB drive.  I am using a galaxy S21.

To elaborate, I tested a SanDisk 32gb ultrafit usb 3. 1 over a usb type c dongle.  My phone can see the usb drive and I can access the files on the drive.  However, when I launch LB it will not see this drive and only see the internal drive.  I believe this is a android 11 shared storage.  Any thoughts.  I believe the drive is formatted fat32.  I use this drive for retroarch on my fire stick to store rooms.  Thanks

Thanks Jason. I appreciate it.  I can see my files on the usb drive through file explorer but neither launch box or retroarch will see the drive inside the respective app.  On my fire stick I can see and load roms directly from the usb using an otg.  Anywho, excited to start using LB.

Okay, well that's interesting. If Retroarch can't see the ROM files, then most likely we won't be able to launch Retroarch regardless. But I'll still dive in and see what I can figure out.

Something I noticed was that my USB drive was being mounted to mnt/media_rw instead of being in /storage.  I think this could be the issue.  I am not too savvy with Android file structure so I don't know why it is showing up there instead of next to internal storage.

Yes, that's probably why. If Android isn't telling us what it is from retrieving all of the storage devices, it'll probably be difficult to find it. I'll be on this soon.

Above is a link that outlines the problem I am having and some folks discussion about it.  As we expected this seems to be caused by android 11.  Thanks for the help.

Did some more digging and looks like external drives will mount to /mnt/media_rw instead of under /storage on android 11.  It is even inaccessible through adb shell.  This the issue for both retroarch and LB.  Other than rooting which most people won't do it seems like both retroarch and LB will need to support the storage access framework in order to use these drives.
