从代码[root]读取当前的APN名称 [英] Read current APN name from code [root]
问题描述
我需要能够读取当前的APN名称.我的应用程序是系统应用程序(位于/system/app下)，并且具有root用户访问权限.
I need to be able to read current APN name. My app is a system app (it's located under /system/app) and I have root access.
我正在尝试获取APN名称，但这是不可能的，因为总是提示我:
I'm trying to get APN name but it's being impossible because I'm always prompted with:
No permission to write APN settings
我还在Android Manifest中添加了以下权限
I also have added the following permissions in Android Manifest
<uses-permission android:name="android.permission.WRITE_APN_SETTINGS"/>
TARGET SDK> 18(棒棒糖)
非常感谢.
