You need to add the android:configure attribute to you widget provider XML. See https://github.com/slightfoot/android-note-widget/blob/master/res/xml/appwidget_note.xml

<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
    android:configure="com.demondevelopers.notewidget.ConfigActivity"
    android:initialKeyguardLayout="@layout/appwidget_note"
    android:initialLayout="@layout/appwidget_note"
    android:minHeight="110dp"
    android:minWidth="180dp"
    android:minResizeWidth="40dp"
    android:minResizeHeight="40dp"
    android:resizeMode="horizontal|vertical"
    android:widgetCategory="home_screen"
    android:updatePeriodMillis="0"
    />
