java - 尽管 AndroidManifest.xml 中提到了，为什么我的 Android 应用程序无法获得某些权限

Question

我正在编写一个 Android 应用程序，通过在 AndroidManifest.xml 中添加以下行，我已向该应用程序授予了以下权限

 <uses-permission android:name="android.permission.INTERNET">
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE">
    </uses-permission>
    <uses-permission android:name="android.permission.READ_PHONE_STATE">
    </uses-permission>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE">
    </uses-permission>
    <uses-permission android:name="android.permission.DELETE_CACHE_FILES">
    </uses-permission>
    <uses-permission android:name="android.permission.DELETE_PACKAGES">
    </uses-permission>
    <uses-permission android:name="android.permission.BROADCAST_STICKY">
    </uses-permission>
    <uses-permission android:name="android.permission.GET_PACKAGE_SIZE">
    </uses-permission>
    <uses-permission android:name="android.permission.INSTALL_PACKAGES">
    </uses-permission>
    <uses-permission android:name="android.permission.READ_FRAME_BUFFER">
    </uses-permission>
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW">
    </uses-permission>
    <uses-permission android:name="android.permission.ACCESS_ALL_DOWNLOADS">
    </uses-permission>

但是我在 LogCat 中收到以下错误。我也无法从 SD 卡中删除软件包，我感觉这是由于缺乏执行此操作的权限。

应用程序无法成功请求所有权限:Android 使用 permissionLevel(“正常”、“危险”、“签名”和“signatureOrSystem”)，即 described here .
