Hi, I was more specific to "*User Space Hardware Abstraction Layer*" which is introduced in Android user space which makes driver implementation in user space different from conventional device driver development. This is more specific to WiFi , BT .. etc.
I would like to know if there is a device which comes with Linux and for which any attempt of porting android is taken, then what specific things need to change or specific API's that needs to be implemented in order to make device work? I understand Linux device driver implementation but this was more specific to user space difference from conventional linux development.
