This app reads an apk file from a url and then ask you to approve theinstallation (do not think it can be done automatically).It also checks periodically if there is a new version to download.You may be wondering what on earth this is good for!I use it when I develop apps for IOIO (http://www.sparkfun.com/products/10748).IOIO is a microcontroller connected to the USB port on an Android phone.You are unable to connect IOIO with Android emulator, so I created this app toeasily upload and test new versions of my IOIO applications on my phone.In other words, as soon as you put a new version of the apk file (new modification date) on your web server, PhoneDeployApp will triggers an installation of it on your phone.
