title: Communication between Chrome Extension and Android Device
body: <p>The question is that i have a project like a QrCode Login base.
  There are a few steps that i already that what is the direction i have to take, like the android apk search in the database if the user exists or the generation of a QrCode in the extension, but the communication between the Extension and the android Device i really don't know.
  Can anybody give me some directions about this communication?
  Thanks.</p>
