Question

我必须在Android上同时使用WiFi和lte。

使用ConnectivityManager，我可以在wifi激活时通过lte发送请求

然而，我从未同时使用过这两者。

我目前使用这些方法。

private static ConnectivityManager cm;
private static NetworkRequest.Builder req;

cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
req = new NetworkRequest.Builder();
req.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);
req.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);
cm.requestNetwork(req.build(), new ConnectivityManager.NetworkCallback() {
    @Override
    public void onAvailable(Network network) {
        //here you can use bindProcessToNetwork
        cm.bindProcessToNetwork(network);
    }
});

有没有办法可以同时申请wifi和lte？

您可以使用NetworkCallback的onAvailable（）来检查网络更改。此外，bindProcessToNetwork（）声明只使用某些网络。使用ConnectivityManager.getAllNetworks（）和我下面的简单示例。

ConnectivityManager connectivityManager = (ConnectivityManager) getApplicationContext()
            .getSystemService(Context.CONNECTIVITY_SERVICE);
Network []networks = connectivityManager.getAllNetworks();
for(int i = 0 ; i < networks.length ; i++) {
    NetworkInfo info = connectivityManager.getNetworkInfo(networks[i]);
    if(info.getTypeName().equals("MOBILE")) {
        // This is mobile network (3G/LTE)
        // Use networks[i].bindSocket(java.net.Socket) for low-level socket communication
        // Use networks[i].openConnection(java.net.URL) for HTTP request
    }
    else if(info.getTypeName().equals("WIFI")) {
        // This is WiFi network
        // Use networks[i].bindSocket(java.net.Socket) for low-level socket communication
        // Use networks[i].openConnection(java.net.URL) for HTTP request

    }
    else {
        // This is another network (WIFI_P2P, Ethernet, Bluetooth, ...)
    }
}

在android中同时请求wifi和lte
