| ↳ | android.view.WindowId |
Safe identifier for a window. This currently allows you to retrieve and observe
the input focus state of the window. Most applications will
not use this, instead relying on the simpler (and more efficient) methods available
on View. This classes is useful when window input interactions need to be
done across processes: the class itself is a Parcelable that can be passed to other
processes for them to interact with your window, and it provides a limited safe API
that doesn't allow the other process to negatively harm your window.
