With the latest version of Android called Marshmallow (6.x) Google have introduced something called ‘Adoptable Storage’ - So what is it and how does this affect Spotify?
Android and Apple have always shunned the use of external memory in their devices as the type, quality and age of the memory used is up to the user and may negatively impact the experience. It may seem like the OS is at fault, when in fact it’s sometimes caused by old or faulty memory cards – Hence why Nexus (and soon to be Android One) or Apple devices do not natively offer the ability to use an SD card in the devices.
However Google have accepted that people will always want expandable memory, and to try and make things easier in Marshmallow they have introduced something called ‘Adoptable Storage’. What this does is convert the SD card into an extension of the internal device memory allowing apps and their data to be stored in this extended file system.
When you insert a card into a device running Marshmallow it will ask you if you want to use the SD card as a portable device or Internal. By selecting portable it will continue to function as before allowing you to remove it without affecting the performance of the phone. By selecting ‘Internal’ you are now moving to the new Adoptable Storage function and the SD card will be formatted and 128-bit AES encrypted before being mounted into the device as Internal memory and part of the system before moving existing apps & their data across.
This is great for devices with small internal memory or for Android TV boxes where the SD card will never be removed. If you try and remove an SD card once you’ve converted it to Adoptable Storage then your phone will start throwing errors at you and apps will start crashing.
So what are the issues Adoptable Storage may cause?
There are several complications this can cause, these are the deciding factors to consider and the last is something to take note of when using Adoptable Storage and apps that require the ability to cache such as Soptify:
Note: If you have set your SD Card to act as 'Internal' you will no longer see the 'Storage' setting in the settings menu of the Spotify application as all memory is classed as Internal so you won;t be able to specify where the cache is to be stored.
How do I convert back to Portable memory from Adopted memory?
To convert an SD back to ‘Portable’ you will first need to backup the existing data by plugging your phone into a PC and copying anything visible on the device over. Once done go to the ‘Storage’ section of Android settings and format the SD card. Once done make sure to restart your phone so that the system correctly identifies the SD card as portable again. Once done, reconnect your phone to the PC and copy all the files previously extracted back onto the portable memory. After this is done it’s best to again reboot the device to ensure links are correctly initiated.
What else has the upgrade to Marshamallow introduced?
In the upgrade to 6.x Marshmallow Google have changed the way application permissions are handled. Sometimes if an application is installed on the device and then you update the device software to Marshmallow these permissions need to be reinitialised. If you are finding that Offline data cannot be stored on an SD card or the SD card is not able to be selected then check the permissions are enabled following the official Android guide here:
Solved! Go to Solution.
Add support for adoptable storage or lose your customers.
I figured it out:
1. delete data and cache for spotify, then uninstall.
2. go to settings --> storage --> SD card --> the three dots in the right upper corner --> migrate data
3. download spotify, but do not start it yet.
4. settings --> apps --> spotify --> move from internal to sd card
5. settings --> apps --> spotify --> add permission for storage
6. fire up spotify, all your songs will end up in the SD card.
I've given up with hope for the Spotify team ever fixes something on Android. I guessing they only have one mediocre Android programmer
