# AppWidgetProvider

*** ** * ** ***

` public class AppWidgetProvider `   
` ` ` extends https://developer.android.com/reference/android/content/BroadcastReceiver ` ` `

|---|---|---|
| [java.lang.Object](https://developer.android.com/reference/java/lang/Object) |||
| ↳ | [android.content.BroadcastReceiver](https://developer.android.com/reference/android/content/BroadcastReceiver) ||
|   | ↳ | android.appwidget.AppWidgetProvider |

<br />

*** ** * ** ***

A convenience class to aid in implementing an AppWidget provider. Everything you can do with AppWidgetProvider, you can do with a regular `https://developer.android.com/reference/android/content/BroadcastReceiver`. AppWidgetProvider merely parses the relevant fields out of the Intent that is received in `https://developer.android.com/reference/android/appwidget/AppWidgetProvider#onReceive(android.content.Context,%20android.content.Intent)`, and calls hook methods with the received extras.

Extend this class and override one or more of the `https://developer.android.com/reference/android/appwidget/AppWidgetProvider#onUpdate(android.content.Context,%20android.appwidget.AppWidgetManager,%20int[])`, `https://developer.android.com/reference/android/appwidget/AppWidgetProvider#onDeleted(android.content.Context,%20int[])`, `https://developer.android.com/reference/android/appwidget/AppWidgetProvider#onEnabled(android.content.Context)` or `https://developer.android.com/reference/android/appwidget/AppWidgetProvider#onDisabled(android.content.Context)` methods to implement your own AppWidget functionality.
