Method for using shared device in apparatus capable of operating two operating systems

摘要

The invention discloses a method for using a shared apparatus in a device capable of running two operating systems, which includes using a first application in a first operating system to communicate with the share apparatus, and when the first operating system is switched to a second operating system, sending associated information on the shared apparatus to a second application in the second operating system so that the second application can use the associated information to communicate with the shared apparatus.
