Galaxy Note-当使用WPA2打开wifi连接时，Android操作系统崩溃（不是应用程序）

有人有过类似的问题吗？对发生的事情有什么线索吗
非常感谢当您使用反射调用setWifiApConfiguration的WifiManager方法时，ssid的WifiConfiguration参数不能为空，否则会导致一些电话系统设置入口，一些电话直接重启，您将看到以下llogcat中的og：

发布日志，我们需要查看崩溃的stacktrace。谢谢@StevenByle，请查看上面的更新1…Android SDK中没有WifiApManager
。那就是makes@Commonware，我是否可以使用另一个类来启用wifi连接？不。但是，我的观点是，当你使用未记录和不支持的东西时，它们将在某些设备和/或某些Android操作系统版本上中断。
