How can I update a widget on receiving a broadcast?

I'm working on a widget that displays information from a completely separate app. The separate app sends a broadcast when its data is changed, and I want to refresh/update my widget upon receiving this broadcast.

I can't seem to work out how to update a widget from within a BroadcastReceiver however. Is there a way to do this? Or another method to get the same result?

If the separate app has special action for its broadcast, you can add the intent filter to the manifest of your widget. Something like this:

<receiver android:name="ExampleAppWidgetProvider" >
    <intent-filter>
        <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        <action android:name="SEPARATE_APP_ACTION" />
    </intent-filter>
    <meta-data android:name="android.appwidget.provider"
               android:resource="@xml/example_appwidget_info" />
</receiver>

And just process it in onRecive method of you AppWidgetProvider. HTH.
