How to differentiate between sdcard and usb mount in android programatically

Question

I am using the following code for getting the external storage mounted in android device.

 val storageManager = CHSSystemApplication.instance.getSystemService(Context.STORAGE_SERVICE) as StorageManager?
        storageManager?.storageVolumes

I mount the sd card and USB it returns the two storage volume. Is there any way we can differentiate between sd card volume and USB.

Answer 1

to get internal SD card

val internalStorage = System.getenv("EXTERNAL_STORAGE")
val f_exts = File(internalStorage )

To get external SD card

val externalStorage = System.getenv("SECONDARY_STORAGE")
val f_secs = File(externalStorage )
