From 4e68bd420b6cfdbeadb5e69aa6448665b2da762b Mon Sep 17 00:00:00 2001 From: Benoit Goby Date: Wed, 25 Apr 2012 18:06:00 -0700 Subject: Add UsbDebuggingManager and UsbDebuggingActivity The UsbDebuggingManager listens to adbd requests and displays a dialog when the public key authentification fails, for the user to confirm if it wants to allow USB debugging from the attached host. If the user chooses to always allow USB debugging, the UsbDebuggingManager writes the public key to adbd's config file so that the public key authenfication succeeds next time.
