Android 读写用户字典权限拒绝

从UserDictionary.Words.CONTENT_URI表中的用户输入中搜索单词的简单应用程序。我正在使用BlueStacks模拟器。 错误日志表明在我的AndroidManifest中没有声明android.permission.READ\u USER\u字典或android.permission.WRITE\u USER\u字典。但我已宣布：

<uses-permission android:name="ANDROID.PERMISSION.READ_USER_DICTIONARY"/>
<uses-permission android:name="ANDROID.PERMISSION.WRITE_USER_DICTIONARY"/>

AndroidManifest：
