Question

我有两个应用程序，让A和B。A中有ContentProvider，其清单声明如下，

<provider
            android:name=".LogProvider"
            android:authorities="com.xxx.LogProvider"
            android:grantUriPermissions="true"
            android:permission="android.permission.READ_XXX_LOGS"
            android:enabled="true"
            android:exported="true"
            android:multiprocess="true"/>

应用程序B正在接收相同的ContentResolver。而且App B也有对应的。但是，只要App A中有内容提供者条目，应用B正在接收其onChange事件。但是，出现以下错误。

I/XTSipListener: onChange, uri = content://com.xxx.LogProvider/error_logs/1
E/XTSipListener: onChange, SecurityException: Permission Denial: opening provider com.xxx.LogProvider from ProcessRecord{bb1084b 22087:com.xxx.AppB/u0a210} (pid=22087, uid=10210) requires android.permission.READ_XXX_LOGS or android.permission.READ_XXX_LOGS

AppB的目标版本为22。由于某些其他功能，因此无法升级。

ContentResolver权限拒绝
