Demo for the Material Witness talk I gave at Google I/O.

Material Witness

A Google I/O 2014 demo written by Romain Guy

Material Witness is a sample application for the new Material Design APIs introduced in the Android L Preview SDK:

  • Custom theme colors
  • Dynamic palette
  • Circular reveal
  • Activity transitions

And a few other things such as colored status and navigation bars, path tracing, etc.

The complete video of the Google I/O 2014 talk detailing how this application works can be found on YouTube.
