title: Can't install unsigned Cordova apk
body: <p>I just built a basic Cordova image, but I can't install it on my Android phone.</p>
  
  <p>It says the package is corrupted.</p>
  
  <p>I have enabled "Trust unknown sources" and copied the file onto my Nexus 6P.</p>
  
  <p>The build process doesn't throw any errors, it creates a <code>android-release-unsigned.apk</code> file as expected.</p>
