Envoyer une demande via des données mobiles lorsque le WIFI est activé (Android L)

SDK: Android 5.0.1.

Version Android: LRX22C.

Appareil: Nexus 5.

Problème: KitKat (4.4.4) et les API inférieures

1) startUsingNetworkFeature(int networkType, String feature) Cette méthode est déconseillée. Obsolète au profit du nettoyeur requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback).

2) requestRouteToHost(int networkType, int hostAddress) Cette méthode est déconseillée. Obsolète au profit de requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback), setProcessDefaultNetwork(Network) et getSocketFactory().

ont été utilisés pour envoyer une demande via Mobile Data Network lorsque le WIFI et les données mobiles étaient activés.

À partir de Android L les API sont obsolètes et ne fonctionnent plus.

De nouvelles API/classes NetworkRequest.Builder, NetworkRequest, ConnectivityManager.NetworkCallback, requestNetwork, registerNetworkCallback ont été utilisées. Détail ici sur l'utilisation de l'API
API Android L

Code:

ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkRequest.Builder builder = new NetworkRequest.Builder();

builder.addCapability(NetworkCapabilities.NET_CAPABILITY_NOT_RESTRICTED);
builder.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);

NetworkRequest networkRequest = builder.build();
connectivityManager.requestNetwork(networkRequest, networkCallback);
connectivityManager.registerNetworkCallback(networkRequest, networkCallback);

Scénario de travail:

Seules les données mobiles sur le rappel onAvailable sont reçues.

Scénario ne fonctionne pas: Mobile et Wifi sont tous les deux allumés et connectés, onAvailable le rappel n'est pas reçu du système. Par conséquent, impossible de définir setProcessDefaultNetwork, ConnectivityManager.setProcessDefaultNetwork(preferedNetwork);

Fréquemment: Toujours

Sortie attendue: Obtenez le rappel avaliabe du réseau mobile lorsque le wifi est activé.

Suis-je en train de manquer quelque chose ici ou le firmware a des problèmes ici?

Eh bien enfin trouvé une solution à cela. L'astuce consistait à utiliser la capacité comme NET_CAPABILITY_INTERNET. Qui est identique à startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, FEATURE_ENABLE_HIPRI);

Voir la conception du firmware ici

builder.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);
builder.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);

Après cela, je suis en mesure d'obtenir le rappel onAvailable du système et plus tard, j'ai défini mon réseau par défaut de processus en tant que données mobiles.

Par conséquent, toute la demande va sur les données mobiles même si le wifi est activé. HOU LA LA!

Remarque: cela ne fonctionnait pas dans les versions initiales de Preview L.

Edit 19-10-2015: setProcessDefaultNetwork est désormais décréé, utilisez bindProcessToNetwork

Voici une fonction qui peut simplifier l'action de préférant certains types de réseaux pour votre application (devrait fonctionner pour n'importe quel niveau d'API actuel (26 au moment de l'écriture):

private void alwaysPreferNetworksWith(@NonNull int[] capabilities, @NonNull int[] transportTypes) {

    NetworkRequest.Builder request = new NetworkRequest.Builder();

    // add capabilities
    for (int cap: capabilities) {
        request.addCapability(cap);
    }

    // add transport types
    for (int trans: transportTypes) {
        request.addTransportType(trans);
    }

    final ConnectivityManager connectivityManager = (ConnectivityManager) getApplicationContext().getSystemService(CONNECTIVITY_SERVICE);

    connectivityManager.registerNetworkCallback(request.build(), new ConnectivityManager.NetworkCallback() {
        @Override
        public void onAvailable(Network network) {
            try {
                if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
                    ConnectivityManager.setProcessDefaultNetwork(network);
                } else {
                    connectivityManager.bindProcessToNetwork(network);
                }
            } catch (IllegalStateException e) {
                Log.e(TAG, "ConnectivityManager.NetworkCallback.onAvailable: ", e);
            }
        }
    });
}

Usage:

// Add any NetworkCapabilities.NET_CAPABILITY_...
int[] capabilities = new int[]{ NetworkCapabilities.NET_CAPABILITY_INTERNET };

// Add any NetworkCapabilities.TRANSPORT_...
int[] transportTypes = new int[]{ NetworkCapabilities.TRANSPORT_CELLULAR };

alwaysPreferNetworksWith(capabilites, transportTypes);
