Answer 1

Specify the android:previewImage attribute in your app widget XML metadata file:

<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
  android:minWidth="146dip"
  android:minHeight="146dip"
  android:updatePeriodMillis="0"
  android:initialLayout="@layout/widget"
  android:autoAdvanceViewId="@+id/words"
  android:previewImage="@drawable/preview"
  android:resizeMode="vertical"
/>
