Android : 알람 또는 서비스가 위젯을 업데이트하기 위해 호출되지 않음

Question

5 ~ 10 초마다 새로 고치는 현재 날짜를 표시하는 위젯을 만들었습니다. 나중에 기간이 길어집니다. onUpdate 메소드에 알람을 작성하여 서비스를 시작하면 위젯이 날짜로 업데이트됩니다. 위젯을 호출 할 때 아무 일도 일어나지 않습니다. 알람 또는 서비스에 문제가 있는지 여부를 모릅니다. 아래 코드를 붙여 넣습니다.

<?xml version="1.0" encoding="utf-8"?> 
    <appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" 
    android:minWidth="146dip" 
    android:minHeight="72dip" 
    android:updatePeriodMillis="1000" 
    android:initialLayout="@layout/main" 
    />  

안드로이드 매니페스트 XML

main.xml에

 <?xml version="1.0" encoding="utf-8"?> 
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:orientation="vertical" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     > 
    <TextView 
     android:id="@+id/scores" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:text="@string/hello" 
    android:paddingTop="35dip" android:paddingLeft="29dip" android:textColor="#000000"/> 
    </LinearLayout> 

에게 .. 제가 잘못 갈 수있는 위치 알고 위젯 제공자 XML을

감사합니다, 샘을 주시기 바랍니다
