title: Android command-line photo
body: <p>I have a nexus4 with a broken touchscreen. Controlling the bootloader with power and volume keys still works, so I put rootbox on it. Now I can login to the root prompt using adt. As I want to use it as timelapse camera, I wonder how is it possible to take a photo and save it to a specific folder using the command line? 
  Then I could set up a cron job and download images using adt.</p>
