如何检查android wifi连接？

Question

I want to check if it is connected to WiFi. If connected, the phone is silent. When the program is running application stopped working

 ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

            if (mWifi.isConnected()) {
                final AudioManager audioManager=
                        (AudioManager)getSystemService(getApplicationContext().AUDIO_SERVICE);
                audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);

            }
            else
            {
                final AudioManager audioManager=
                        (AudioManager)getSystemService(getApplicationContext().AUDIO_SERVICE);
                audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
            }

Answer 1

you can directly use this method if connect then it will return true else false remember it will not work on Emulator please test it on real device .. Thanks

private boolean isNetworkAvailable() {
        ConnectivityManager connectivityManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo netInfo = connectivityManager.getActiveNetworkInfo();
        if(netInfo != null && netInfo.isConnected()) {
            //we are connected to a network
            return true;
        }
        else
            return false;
    }
