Android: Adding data to Intent fails to load Activity

I think you need a <data> tag in your <intent-filter> in order for the intent you are firing to match the intent-filter you have registered.

Also using Uri.EMPTY may be a problem. I'd create your own Uri scheme, so that your setData() call looks something like:

di.setData(Uri.withAppendedPath(Uri.parse("droidln://widget/id/"), String.valueOf(appWidgetId)));

and your intent-filter would look like:

    <intent-filter>
        <action android:name="bostone.android.search.RESULTS" />
        <category android:name="android.intent.category.DEFAULT" />
        <data android:scheme="droidln"/>
    </intent-filter>
