Android: Creating custom AppWidgets

App Widgets are very small scale application window that shows information updates to user and lies on home screen. It is nice feature on Android to show crucial application data at home screen with tiny space.

It can be updated periodically as configured in app widget meta data. It can also be updated when it is clicked or tapped.

There two types of design layout for app widgets such as

  1. Portrait widgets dimensions- 4×1 cells (80*4 by 100 * 1) dp, 3×3 ,  2×2
  2. Landscape widgets dimensions –  4×1 (106*4 by 74*1)dp, 3×3, 2×2

If you want to create custom app widget then you should follow some steps as following.

  1. Create MyAppWidget layout into … res/layout/myappwidget_layout.xml – it’s the actual widget layout that will be shown in home screen. Add, for example, a TextView in this layout.
  2. Create xml directory in path … MyProject/res/xml
  3. Add MyAppWidgetProviderInfo, metadata file, where you define attributes of Appwidget …/res/xml/my_appwidgetprovider_info.xml
  4. Create MyAppWidgetProvider extends AppWidgetProvider and handles events onEnable(),  onUpdate(….),  onReceive(...) etc. Here you implement the View updates logics.
  5. Declare app widget receiver/provider class in AndroidManifest.xml
  6. Run this app widget project and find the MyAppWidget in widgets list and install from there. Then you will find that in home screen.
