我需要我的应用程序重置设备的移动网络信号。这将有可翻转飞行模式,其中的连接暂时丢失,新的IP地址重新连接时分配的,在状态栏上的LTE /信号图标应该会消失,然后重新连接时再次出现同样的效果。我发现上,我测试的Play商店应用运行Android在手机上用的CyanogenMod 4.4.4,它正是这样做的,但我不能确定我怎么能在我自己的应用程序实现这一点。我认为这是关系到 CHANGE_NETWORK_STATE
许可。我要求的文档或者一些简单的例子,code将重置网络连接。
I need my app to reset the device's mobile network signal. This would have the same effect as toggling airplane mode where connectivity is temporarily lost, a new IP address is assigned upon reconnection, and the LTE/signal icon in the status bar should disappear and then reappear upon reconnection. I found an app on the Play Store that I tested on my phone running Android 4.4.4 with CyanogenMod and it does exactly this, but I am unsure as to how I can implement this in my own app. I think it's related to the CHANGE_NETWORK_STATE
permission. I am seeking documentation or some simple example code that will reset the network connection.
请注意,我不是的专门的尝试切换飞行模式,而是在上面链接的应用程序的方式做移动数据重置,因为我已经测试它确实工作,甚至不需要root权限。
Note that I am not specifically trying to toggle airplane mode, but rather to reset the mobile data in the way that the app linked above does, as I have tested that it indeed works without even requiring root privileges.
