I was asked this morning to take a look at the Photo Album tutorial as AppBuilder has been chosen as our development platform for an upcoming project. I will say that I was quite impressed with the emulation tools, especially considering that anything is web-based.
However, I ran into a bit of a problem on step 3, "Deploy your app using the companion app". I downloaded the AppBuilder onto my Android (Droid Mini, running 4.4.4) and scanned the QR code generated by the build process. After AppBuilder downloads the app, it fails with this error:
"Your project does not target Apache Cordova 3.6.4 and might not run properly."
