java code

 public class detectremoved extends broadcastreceiver {         @override         public void onreceive(context context, intent intent) {             string[] packagenames = intent.getstringarrayextra("android.intent.extra.packages");              if(packagenames!=null){                 for(string packagename: packagenames){                     if(packagename!=null && packagename.equals("activity_log.pargansystem.com.activity_log")){                         toast.maketext(context, "your message", toast.length_short).show();                         // start activity here , ask user password                     }                 }             }         }     }
