现在的问题是，查询已经进入了MenberContentProvider类了,但是query返回的cursor,遍历发现没有数据.
然后在控制台的信息显示
No content provider found for:
究竟是哪里出错了？求解！！！ --------------------编程问答-------------------- 你这个Uri MLGBDatabaseMetaData.MemberTableMetaData.CONTENT_URI的值是多少？
要跟你的autorities对应：
android:authorities="com.contentprovider.membercontentprovider" --------------------编程问答--------------------
其实是部署的时候出现这个错误

就是无法找到
后来我调用 联系人数据也是这个错，但是没有解决这个问题
补充：移动开发 , Android
