InsertAPN（）方法不写APN设置 - Android的2.3.6 [英] InsertAPN() Method Does Not Write APN Settings - Android 2.3.6
本文介绍了InsertAPN（）方法不写APN设置 - Android的2.3.6的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有这应该是我每次运行新的APN设置似乎并没有被写入到设备的应用程序时写入新的APN设置，但是设备的Android应用程序（APN设置在执行后完全空白）我相信的，这可能有事情做与InsertAPN（有问题）[如下]但是我无法确定问题的根源。
P.S。
任何调试提示/问题是很大的AP preciated。

解决方案
您不能再编程上的Android 4.0及以上更改APN设置。所以，如果你在Android 4.0或更高版本的调试，这是你的问题。
I have an android application which is supposed to write new APN settings to a device however every time I run the application the new APN settings do not appear to be written to the device (the APN settings are totally blank after execution) I belive this may have something to do with a problem with InsertAPN() [shown below] however I'm unable to determine the root cause of the issue.
P.S.
Any debugging tips/questions are greatly appreciated.
