Widget doesn show on emulator or devices and no errors showing

Question

I'm new to android development. At the moment I'm trying to write an app widget. I've done a few widget tutorials and when I go to run them the app will run but the widget isn't showing up on the widget list to be used. Widgets that are not extensions of an app still will run as if they are an app and will not show up in the widgets list. This is happening with all the widgets iv tried to run. No errors are showing. Somebody please help its driving me mad. Thanks

There is a typo in your manifest. This:

<action android:name="android.appwidget.action.APPWIGET_UPDATE"/>

should be changed to this:

<action android:name="android.appwidget.action.APPWIDGET_UPDATE"/>

Notice the missing "D" in "APPWIGET_UPDATE" in the original.
