Sending a response after app starting from a intent-filter

Question

I'm trying to implement the PICK and SET_WALLPAPER intent-filter, and so far I've got them in the context menu, but how do I respond back to whoever started the app that way? Lets say I have the activity:

<activity
    android:name="ListActivity"
    android:label="@string/app_name" >
    <intent-filter>
        <action android:name="android.intent.action.SET_WALLPAPER" />

        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

When this activity is successfully running, and I know what image (I know it's location on external storage, and could have a Bitmap of it), how do I send this response back so that the app that started my app can use the response? I'm thinking finish(), but what extras do I then add? Does this come down to the specific app that started my app? Thank you.

You can look here for an example of returning from an intent called with startActivityForResult(). I'm assuming that's how it is called from the system. However, I don't know what sort of result you need respond with.

[edit] Actually I don't think you have to return anything. Just set your wallpaper with the WallpaperManager or whatever and finish() your activity.
