Home Screen Widgets

"Home Screen Widgets" is widget that people can drop onto their home screen and interact with. It can provide a quick glimpse into full-featured apps, such as showing upcoming calendar events, or viewing details about a song playing in the background.

When widgets are dropped onto the home screen, they are given a reserved space to display custom content provided by your app. Users can also interact with your app through the widget, for example pausing or switching music tracks. If you have a background service, you can push widget updates on your own schedule, or the AppWidget framework provides an automatic update mechanism.

In the coming articles, I will show how to create Home Screen Widgets step-by-step.

  • Starting in Android 3.1, developers can make their homescreen widgets resizeable — horizontally, vertically, or on both axes. Users touch-hold a widget to show its resize handles, then drag the horizontal and/or vertical handles to change the size on the layout grid.
  • Starting from Android 4.0, home screen widgets should no longer include their own padding. Instead, the system now automatically adds padding for each widget, based the characteristics of the current screen. This leads to a more uniform, consistent presentation of widgets in a grid.
