android bug orientation View not attached to window manager

  • When you switch orientations, Android will create a new View. You're probably getting crashes because your background thread is trying to change the state on the old one.

  • QuickActions can be used as a replacement for our traditional dialog invoked by long press.
  • The dashboard pattern serves as a home orientation activity for your users. It is meant to include the categories or features of your application. We recommend including an Action bar on this screen as well. The dashboard can be static or dynamic. For example, in the case of our dashboard for Twitter, we used the goodness of Live Wallpapers introduced in 2.1 to create an animated dashboard complete with real-time trend bubbles and the Twitter bird silhouette.
  • You keep a search history so users upon returning to the search activity can have quick one-button access to previous searches.
