Export Layout and update via SD Card

Can I export a saved working layout to an SD card and then update an offline android player with this SD card?
Having an ‘always on’ connection is not possible in this instance.
I appreciate that the license needs to be checked every 30 days but it would be a useful content update method

The Android player doesn’t have any offline update capability at present. Exporting layouts is there for backup/transfer to a different CMS capability and isn’t in a format suitable for a Player.
