AppWidgetProvider, onUpdate gets called several times on start

I have a problem regarding AppWidgetProvider. When the phone starts up the onUpdate() method for the AppWidgetProvider gets called four times in a row, all containing the same appWidgetId. I can't figure out why it's happening. Does anyone have a clue?

I got two types of super classes, Main and MainScroll, and four classes(widgets) that extends the super classes.

Example widget

public class WidgetMedium extends Main {

    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent);
    }

}

The manifest

        <receiver android:name=".activity.Main">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>
    </receiver>

    <receiver android:name=".activity.MainScroll">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>    
    </receiver>

    <receiver android:name=".activity.WidgetMedium"
        android:label="Swedroid Widget 4x3"
        android:icon="@drawable/widget_application">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>
        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/widget_provider_medium" />
    </receiver>

    <receiver android:name=".activity.WidgetScrollMedium"
        android:label="Swedroid Widget 4x3 Scroll"
        android:icon="@drawable/widget_application">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>
        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/widget_scroll_provider_medium" />
    </receiver>

     <receiver android:name=".activity.WidgetLarge"
        android:label="Swedroid Widget 4x4"
        android:icon="@drawable/widget_application">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>
        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/widget_provider" />
    </receiver>

    <receiver android:name="com.swedroid.widget.activity.WidgetScrollLarge"
        android:label="Swedroid Widget 4x4 Scroll"
        android:icon="@drawable/widget_application">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>
        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/widget_scroll_provider_large" />
    </receiver>

If Main and MainScroll classes are only super classes I thing they shouldn't be AppWidgetProviders but rather abstract classes, therefore, the receiver definitions are not needed for them in the Manifest.

Also I think the intent-filter below is not needed for the other four reciever definitions.

<intent-filter>
    <action android:name="android.intent.action.MAIN" />
    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

I think that all four receivers in your case are active and they all receive the same intent to update your widget. Could you please add the code where you create update intent in your application?
