android - java.lang.InstantiationException: class has no zero argument constructor -


i trying use broadcastreceiver inner class track network state got exception in title. should fix problem? 

public class networkchangereceiver extends broadcastreceiver {     public networkchangereceiver() {     }      @override     public void onreceive(context context, intent intent) {         final connectivitymanager connmgr = (connectivitymanager) context                 .getsystemservice(context.connectivity_service);          final android.net.networkinfo wifi = connmgr.getnetworkinfo(connectivitymanager.type_wifi);          final android.net.networkinfo mobile = connmgr.getnetworkinfo(connectivitymanager.type_mobile);          if (wifi.isavailable() || mobile.isavailable()) {             setupdata();             log.d("netowk available ", "flag no 1");         }      } }

your

inner broadcast receiver must static ( registered through manifest)

or

non-static broadcast receiver must registered , unregistered inside parent class

for this.

i using inner broadcast reciver, without registering within class. either make static , register in manifest , or make non static , register , unregister inside parent class .
