android - queda - porque mi lg no agarra el wifi

Enviar solicitud a través de datos móviles cuando está activado WIFI.(Android L)

Question

SDK: Android 5.0.1.

Android build: LRX22C.

Dispositivo: Nexus 5.

Problema: KITKAT (4.4.4) y debajo de API

1) startUsingNetworkFeature(int networkType, String feature) Este método está en desuso. Obsoleto a favor de la requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback) más requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback) .

2) requestRouteToHost(int networkType, int hostAddress) Este método está en desuso. Obsoleto a favor de requestNetwork(NetworkRequest, ConnectivityManager.NetworkCallback) , setProcessDefaultNetwork(Network) y getSocketFactory() .

se utilizaron para enviar solicitudes a través de la red de datos móviles cuando estaban activados los datos WIFI y móviles.

Al iniciar Android L, la API está obsoleta y ya no funciona.

Se utilizaron las nuevas API / clases NetworkRequest.Builder , NetworkRequest , ConnectivityManager.NetworkCallback , requestNetwork , registerNetworkCallback . Detalle aquí sobre el uso de API
Android L API

Código:

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);

Escenario de trabajo:

Solo se reciben los datos móviles en la onAvailable llamada disponible.

No funciona. Escenario: tanto móvil como Wifi están encendidos y conectados. onAvailable devolución de llamada no se recibe del sistema. Por lo tanto, no puede establecer setProcessDefaultNetwork , ConnectivityManager.setProcessDefaultNetwork(preferedNetwork);

Frecuentemente: Siempre

Salida esperada: obtenga una devolución de llamada avaliabe de la red móvil cuando el wifi esté encendido.

¿Me falta algo aquí o el firmware tiene algunos problemas aquí?

Answer 1

Aquí hay una función que puede simplificar la acción de preferir ciertos tipos de redes para su aplicación (debería funcionar para cualquier nivel de API actual (26 al momento de la escritura):

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);
}
}
});
}

Uso:

// 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);

Answer 2

Bueno, finalmente encontramos la solución para esto. El truco era usar la capacidad como NET_CAPABILITY_INTERNET . Que es lo mismo que startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, FEATURE_ENABLE_HIPRI);

Vea el diseño del Firmware aquí

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

Después de esto, puedo onAvailable devolución de llamada disponible desde el sistema y luego establecer mi red predeterminada del proceso como datos móviles.

Por lo tanto, toda la solicitud pasa por los datos móviles, incluso si wifi está activado. ¡GUAUU!

Nota: Esto no estaba funcionando en las versiones iniciales de Preview L.
