Eins der übersehenen Features von Ice Cream Sandwich scheint die Stifteingabe zu sein. Damit steht jeder App der Zugriff auf die APIs frei und alle können, wenn sie denn wollen, die Eingabe über Stifte einfach realisieren. Darüber hinaus lassen sich dann auch relativ einfach Handschrifterkennungssysteme realisieren. Für das Upgrade des Galaxy Note können sich die Entwickler also schon mal etwas mehr zurücklehnen. Die genaue Erklärung der verfügbaren Optionen für Entwickler nach dem Break.



Stylus input, button support, hover events

Android 4.0 includes full support for stylus input events, including tilt and distance axes, pressure, and related motion event properties. To help applications distinguish motion events from different sources, the platform adds distinct tool types for stylus, finger, mouse, and eraser. For improved input from multi-button pointing devices, the platform now provides distinct primary, secondary, and tertiary buttons, as well as back and forward buttons. Hover-enter and hover-exit events are also added, for improved navigation and accessibility. Developers can build on these new input features to add powerful interactions to their apps, such as precise drawing and gesturing, handwriting and shape recognition, improved mouse input, and others.
