Android L support #1

Closed matttbe closed 6 years ago

matttbe commented 9 years ago

It is currently not planed to support Android 5 but it's possible that we will have to change a bit the way to use the cellular interface when the WiFi one is enabled.

Let's write here this tip to not forget it :-)

Well finally found solution for this.Trick was to use capability as NET_CAPABILITY_INTERNET.Which is same as "startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, FEATURE_ENABLE_HIPRI);"

See the Firmware design here
builder.addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);
builder.addTransportType(NetworkCapabilities.TRANSPORT_CELLULAR);
After this i am able to get onAvailable callback from system and later i set my process default network as mobile data.

Hence all the request goes over Mobile data even if wifi is on.WOW!

Note: This was not working in initial releases of Preview L.

Can you direct on how to integrate this code to the existing code i.e. How to replace the deprecated startUsingNetworkFeature with this code?

Hi @tarunmangla,

Two techniques are used to maintain active both LTE and WiFi connections:

ask for High Priority feature (we need LTE "just in case"): https://github.com/MPTCP-smartphone-thesis/MultipathControl/blob/master/MultipathControl/src/be/uclouvain/multipathcontrol/ifaces/MobileDataMgr.java#L73
create a "fake" connection with High Priority feature (we need LTE while this connection is alive): https://github.com/MPTCP-smartphone-thesis/MultipathControl/blob/master/MultipathControl/src/be/uclouvain/multipathcontrol/ifaces/MobileDataMgr.java#L115

Note that it is possible to check the version of Android in the code:

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
     // see https://developer.android.com/reference/android/os/Build.VERSION_CODES.html
}

@tarunmangla can you please specfy the code how to implement on that in below code.

    public void setMobileDataActive(boolean mEnabled) {
        if (Manager.DEBUG)
            Log.d(Manager.TAG, "setMobileDataActive " + new Date());

        ConnectivityManager cManager = (ConnectivityManager) context
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        if (isMobileDataEnabled() && isWifiConnected() && mEnabled)
            cManager.startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE,
                    "enableHIPRI");
        else
            cManager.stopUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE,
                    "enableHIPRI");
    }

This should now be supported thanks to the new branch from @qdeconinck : https://github.com/MPTCP-smartphone-thesis/MultipathControl/tree/marshmallow
