android里的contentprovider中出现的问题

java.lang.SecurityException: Permission Denial: opening provider com.itcast.db.PersonProvider from ProcessRecord{40f82218 23563:com.example.aapp/u0a10079} (pid=23563, uid=10079) that is not exported from uid 10074
在AndroidManifest.xml 中给亩袜ContentProvider 的定义里面加上个android:exported="蔽庆true" 就可以迅并激了
这是没权限吧
