title: Adb over network without previous USB pairing
body: <p>I have an android 4.2.2 that requires the ADB connection to match an approved fingerprint.</p>
  
  <p>The problem is that the device need to be paired using a USB cable the first time which in my situation will be a problem.</p>
  
  <p>My development environment is running in VirtualBox and I have previously given up trying to get USB to work and instead used the ADB over the network.</p>
  
  <p>The Android SDK Platform-tools is the latest 1601.</p>
  
  <p>Is there any way for me to manually add the key from the virtual machine to my device?</p>
  
  <p>I have a working Android SDK on my host and root access to my device if that can be used to fix this.</p>
