Demonstrating morphing a search icon into a search field. To do this we use an AnimatedVectorDrawable (https://developer.android.com/reference/android/graphics/drawable/AnimatedVectorDrawable.html) made up of two paths. The first is the search icon (as a single line) the second is the horizontal bar. We then animate the 'trimPathStart' property …

Demonstrating an animation for scanning a fingerprint and showing success or failure. This uses a number of AnimatedVectorDrawables (https://developer.android.com/reference/android/graphics/drawable/AnimatedVectorDrawable.html) to 'morph' parts of the fingerprint into the tick or cross to report success or failure. It also uses a moving clip-pat…
