无法使用OkHttp通过WIFI连接到外部设备(相机)的本地IP

Question

我有一个360 Insta Camera，它使用OKHttp与WIFI连接到android手机，并且应该连接到Local Ip (192.....)！

问题：

当移动数据和wifi都启用时，在android 11和12中，当用户启用Automatic Switch connection选项时，操作系统为Mobile Data设置了优先级，问题发生了！摄像头无法连接到手机，因为当设备有互联网时，它会在网络中查找IP！

如何使用OKHttp解决此问题？

Answer 1

您可以使用类似以下的东西来固定网络

OkHttp路由流量抛出wifi和SocketFactory

final Network[] networks = connectivityManager.getAllNetworks();
for (final Network network : networks) {
final NetworkInfo netInfo = connectivityManager.getNetworkInfo(network);
if (netInfo.getType() == ConnectivityManager.TYPE_WIFI && netInfo.getState() == NetworkInfo.State.CONNECTED) {
// just for example HttpURLConnection works as expected and route traffic throw wifi
connection = (HttpURLConnection) network.openConnection(url);
// not works since >=3.5.0, route traffic in same way
builder.socketFactory(network.getSocketFactory());
}
}
