Connectivitymanager.extra_no_connectivity Is Always False On Android Lollipop

I am using this piece of code to detect Internet connection state changes. It works fine on Android<5.0, but on API 21 this: intent.getExtras().getBoolean(ConnectivityManager.EX

Solution 1:

You can use NetworkRequest added in API level 21.

Create a custom intent action:

publicstaticfinalStringCONNECTIVITY_ACTION_LOLLIPOP="com.example.CONNECTIVITY_ACTION_LOLLIPOP";

Create the new method registerConnectivityActionLollipop:

@TargetApi(Build.VERSION_CODES.LOLLIPOP)privatevoidregisterConnectivityActionLollipop() {

    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
        return;

    ConnectivityManagerconnectivityManager= (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkRequest.Builderbuilder=newNetworkRequest.Builder();

    connectivityManager.registerNetworkCallback(builder.build(), newConnectivityManager.NetworkCallback() {
        @OverridepublicvoidonAvailable(Network network) {
            Intentintent=newIntent(CONNECTIVITY_ACTION_LOLLIPOP);
            intent.putExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false);

            sendBroadcast(intent);
        }

        @OverridepublicvoidonLost(Network network) {
            Intentintent=newIntent(CONNECTIVITY_ACTION_LOLLIPOP);
            intent.putExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, true);

            sendBroadcast(intent);
        }
    });
}

Add the new intent action to the intent filter and call registerConnectivityActionLollipop:

IntentFilterintentFilter=newIntentFilter();
intentFilter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
intentFilter.addAction(CONNECTIVITY_ACTION_LOLLIPOP);

registerReceiver(mBroadcastReceiver, intentFilter);
registerConnectivityActionLollipop();

Change the BroadcastReceiver to support the new intent action:

privateBroadcastReceivermBroadcastReceiver=newBroadcastReceiver() {
    @OverridepublicvoidonReceive(Context context, Intent intent) {

        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP && TextUtils.equals(intent.getAction(), ConnectivityManager.CONNECTIVITY_ACTION) ||
                Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP && TextUtils.equals(intent.getAction(), CONNECTIVITY_ACTION_LOLLIPOP)) {

            if (intent.getExtras() != null) {
                finalConnectivityManagerconnectivityManager= (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
                finalNetworkInfonetworkInfo= connectivityManager.getActiveNetworkInfo();
                if (networkInfo != null && networkInfo.isConnectedOrConnecting()) {
                    Log.d("receiver test", "detected on");
                }
            }

            Log.d("receiver test", Boolean.toString(intent.getExtras().getBoolean(ConnectivityManager.EXTRA_NO_CONNECTIVITY)));
            if (intent.getExtras().getBoolean(ConnectivityManager.EXTRA_NO_CONNECTIVITY, Boolean.FALSE)) {
                Log.d("receiver test", "detected off");
            }
        }
    }
};
