title: Running Custom Android ROM on Emulator
body: <p>I built a custom ROM based out of AOSP (7.0 for Nexus 6) and I would like to use this ROM with SDK emulator. The lunch combo for the build is 'aosp_x86_64-eng' which I believe </p>
  
  <p>should work on SDK emulator. However, I don't see an option in AVD Manager to specify my custom system image. It only allows me to use the listed ROMs from Google.</p>
  
  <p>I tried copying my custom ROM's system.img over the stock Nexus 6 AVD but the emulator doesn't launch after that.</p>
  
  <p>Note that the emulator that gets generated during the build works fine. But the build happens on a server, and I want to use the generated ROM on my development machine with my SDK's AVD Manager.</p>
