Java InsertAPN（）方法不写入APN设置-Android 2.3.6
我有一个android应用程序，它应该向设备写入新的APN设置，但是每次我运行该应用程序时，新的APN设置似乎不会写入设备（执行后APN设置完全为空），我相信这可能与InsertAPN（）的问题有关[如下所示]但是，我无法确定问题的根本原因 附言 非常感谢任何调试提示/问题 源代码段：Java InsertAPN（）方法不写入APN设置-Android 2.3.6,java,android,android-contentresolver,android-cursor,access-point-name,Java,Android,Android Contentresolver,Android Cursor,Access Point Name,我有一个android应用程序，它应该向设备写入新的APN设置，但是每次我运行该应用程序时，新的APN设置似乎不会写入设备（执行后APN设置完全为空），我相信这可能与InsertAPN（）的问题有关[如下所示]但是，我无法确定问题的根本原因 附言 非常感谢任何调试提示/问题 源代码段： /* * Insert a new APN entry into the system APN table Require an apn name, and * the apn address.
