Wyślij żądanie przez dane mobilne, gdy WIFI jest włączone.(Android L)

SDK: Android 5.0.1.

Android build: LRX22C.

Urządzenie: Nexus 5.

Problem: KITKAT (4.4.4) i poniżej API

1) startUsingNetworkFeature(int networkType, String feature) Ta metoda jest przestarzała. Deprecated for the cleaner requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback).

2) requestRouteToHost(int networkType, int hostAddress) Ta metoda jest przestarzała. Deprecated for the requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback), setProcessDefaultNetwork(Network) i getSocketFactory().

Były używane do wysyłania żądań przez mobilną sieć danych, Gdy WIFI i dane mobilne były włączone.

Uruchamianie Androida L API jest przestarzałe i już nie pracuje.

Nowe API/klasy NetworkRequest.Builder, NetworkRequest, ConnectivityManager.NetworkCallback, requestNetwork, registerNetworkCallback zostały użyte. szczegóły tutaj na temat użycia API
Android L API ' s

Kod: 

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);

Scenariusz Pracy:

Odbierane są tylko dane komórkowe na onAvailable oddzwanianie.

Nie działa Scenariusz: Zarówno telefon komórkowy, jak i Wifi są włączone i połączone, onAvailable callback nie jest odbierany z systemu. Stąd nie można ustawić setProcessDefaultNetwork, ConnectivityManager.setProcessDefaultNetwork(preferedNetwork);

Często: Zawsze

Oczekiwane wyjście: Get mobile network avaliabe callback when wifi is on.

Czy coś mi tu umyka, czy firmware ma tu jakieś problemy?

W końcu znalazłem na to rozwiązanie. Sztuczka polegała na użyciu możliwości jako NET_CAPABILITY_INTERNET. Który jest taki sam jak startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, FEATURE_ENABLE_HIPRI);

Zobacz projekt Firmware tutaj 

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

Po tym jestem w stanie uzyskać onAvailable callback z systemu, a później ustawić mój proces domyślnej sieci jako danych mobilnych.

Stąd wszystkie żądania przechodzą przez dane mobilne, nawet jeśli wifi jest włączone. WOW!

Uwaga: To nie działało w pierwszych wydaniach Preview L.

Edycja 19-10-2015: setProcessDefaultNetwork jest teraz depcreated użyj bindProcessToNetwork

Oto funkcja, która może uprościć działanie preferując określone typy sieci dla Twojej aplikacji (powinna działać na dowolnym obecnym poziomie API (26 od momentu napisania): 

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);
            }
        }
    });
}

Użycie: 

// 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);
