widget_info.xml

<appwidget-provider      xmlns:android="http://schemas.android.com/apk/res/android"     android:minwidth="25dp"     android:minheight="25dp"     android:initiallayout="@layout/widget"     android:configure="com.demo.widgetconfig"      android:widgetcategory="home_screen|keyguard"      android:previewimage="@layout/widget"      android:resizemode="horizontal|vertical"      android:initialkeyguardlayout="@layout/widget"      android:minresizeheight="5dp"      android:minresizewidth="5dp"> </appwidget-provider> 

but when try load widget, toast "app isnt installed", not showing such toast comes??

why image not setting, how fix it??

make sure have correct package name set in "android:configure" field in appwidget-provider xml , , have correct intetn-filter set in manifest file.
