How can one detect airplane mode on Android

Question

I have code in my application that detects if Wi-Fi is actively connected. 

That code triggers a RuntimeException if airplane mode is enabled. 

I would like to display a separate error message when in mode is activated. How can I reliably detect if an Android device is in airplane mode?

Hello,

When registering the Airplane Mode BroadcastReceiver (@saxos answer) I think it makes a lot of sense to get the state of the Airplane Mode setting right away from the Intent Extras in order to avoid calling Settings.Global or Settings.System :

@Override
public void onReceive(Context context, Intent intent) {

    boolean isAirplaneModeOn = intent.getBooleanExtra("state", false);
    if(isAirplaneModeOn){

       // handle Airplane Mode on
    } else {
       // handle Airplane Mode off
    }
}

Hope this work!!
