Android : Error when adding widget : Unfortunately, "MyApp" has stopped

I made an app with a widget, and when I add or remove the widget on my phone, or restart my phone with the widget on my homescreen, it comes up with an error "Unfortunate, Clock has stopped." (Clock is the name of my app.) The widget works fine, but I need to get rid of the error message. Eclipse didn't say that there was any problem.

Manifest

<receiver android:name="com.tzemachzr.clock.ClockWidgetProvider">
<intent-filter>
  <action
     android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data
  android:name="android.appwidget.provider"
  android:resource="@xml/clock_appwidget" />
</receiver>

Widget Layout

<?xml version="1.0" encoding="utf-8"?>
<AnalogClock xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >


</AnalogClock>

App Widget Provider

<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:minHeight="140dp"
android:minWidth="140dp"
android:initialLayout="@layout/clock_appwidget_layout" android:resizeMode="horizontal|vertical">

</appwidget-provider>
