I had this issue yesterday on rpi b+ with class 10 16gb running jessie.
When installing directly from Android app onto a new raspbian image the setup halts at “resizing and rebooting”. I have to log in to the rasperry and resize sd card manually in raspi-config, then I can start the installation again from the app and it installs like normal.
That sounds about right. We are working on updating the Cayenne installer to automatically expand the file system when it was not previously expanded, which should get rid of this problem.
