Currently I think this is the only way to get the free space of each StorageVolume:

        val storageManager = getSystemService(Context.STORAGE_SERVICE) as StorageManager
        val storageVolumes = storageManager.storageVolumes
        AsyncTask.execute {
            for (storageVolume in storageVolumes) {
                val uuid: UUID = storageVolume.uuid?.let { UUID.fromString(it) } ?: StorageManager.UUID_DEFAULT
                val allocatableBytes = storageManager.getAllocatableBytes(uuid)
                Log.d("AppLog", "allocatableBytes:${android.text.format.Formatter.formatShortFileSize(this,allocatableBytes)}")
            }
        }

However, I can't find anything about getting the total size that is on the storageVolume.

And I'm not even sure if this is how it's done for getting the free space.

Please provide official way to get them both
