I have a way to do it without any code e.g.:
In your resvalues dir create a bools.xml file:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<bool name="honeycombOrAbove">false</bool>
</resources>
Create a values-v11 dir (for honeycomb or above values), copy the file to it and set the value to true.
Then in the manifest for the widget receiver use: android:enabled="@bool/honeycombOrAbove". I also used it in the configuration activity for the widget.
This means the widget is disabled at install time.
