I am working on an application where I need to detect the sd card id only when the card is present on the device. I have viewed and tried this link and it solves my problem: Android get id of SD Card programmatically

But I didn't understand the exact meaning of mmcblk0 and mmcblk1, although I got that they are volume partitions of the memory.
Is anyone aware of that ? Please help if u know about the concept.
Thanks in advance !!

Here, mmcblk0 is the internal NAND, and mmcblk1 is the external sd card.

  • thanks for answering but is it confirmed that mmcblk1 always points to the external sd card in any device ? – Pragya Oct 14 '14 at 05:58
