    </activity> 

    <provider 
     android:name=".TasksContentProvider" 
     android:authorities="pl.example.tasks" /> 
</application> 

내 taskssync.xml입니다 :

<sync-adapter xmlns:android="http://schemas.android.com/apk/res/android" 
    android:accountType="com.google" 
    android:contentAuthority="pl.example.tasks" 
    android:supportsUploading="false" 
    android:userVisible="true" />

제공자 노드에 android:syncable="true" 속성이 필요하다고 생각합니다. 그래서 :

<provider 
    android:name=".TasksContentProvider" 
    android:authorities="pl.example.tasks" 
    android:syncable="true" />
