hi,
i solved this issue recently.
if you don't want to start with activity, you can hide an initial activity
with the source below.
1. add an android theme to hide
<activity
android:name=".InfoActivity" *
android:theme="@android:style/Theme.Holo.Light.Panel"
* android:label="@string/title_info">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category
android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
2. finish the activity as soon as it starts
and you can see the widget in the list after the first installation.
