title: Specify package name when building Android application
body: <p>I have an Android application that is brand-able. We were using SDK v15 (4.0.x) and when building the application through ant, we would specify package.name=com.blah.brand in the ant properties script. This would allow us to install the same application multiple times on the device but each would be it's own application and settings.</p>
  
  <p>Since upgrading to SDK v16 (4.1), this no longer works and I am unable to find a way to change the packing name when building the application. Does anyone know the new way on how to do this?</p>
