I'm getting this warning for my AppWidget's configuration activity in the manifest file after I added the `android:exported="true"` tag. This is what it looks like...

```
<activity android:name=".widgets.WidgetConfigurationActivity"
              android:theme="@android:style/Theme.Translucent"
              android:exported="true" >
         <intent-filter>
               <action android:name="android.appwidget.action.APPWIDGET_CONFIGURE" />
         </intent-filter>
</activity>

```

The warning I'm getting is "Exported activity does not require permission". From my understanding, setting the `exported` tag to true means that another application not related to my app can access it (which would make sense since the home screen launcher apps needs to launch my AppWidget's configuration activity). Does anyone know what kind of permission I need to add here to make this not give an error?
