Since you'll be traveling through time, you might end up in an era that (Gasp!) doesn't have wifi. Create an intent filter with the connectivity action: "android.net.conn.CONNECTIVITY_CHANGE". Then register it using the receiver variable already declared as a class member variable.

i don't know where i am getting it wrong. i thought i have already registered

can someone help

TimeTravelActivity.java 
import android.os.Bundle;
import android.view.View;

public class TimeTravelActivity extends Activity {

  public String targetYear;

  private NetworkConnectionReceiver receiver = new NetworkConnectionReceiver();

 @Override
    protected void onResume ()  {
      super.onResume ();
      IntentFilter filter = new IntentFilter("android.net.conn.CONNECTIVITY_CHANGE");registerReceiver(mReceiver, filter);

    }
      @Override
  protected void onPause () {
    super.onPause ();
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_time_travel);




    Intent intent = getIntent();
    targetYear = intent.getStringExtra("EXTRA_YEAR");
    EnergySource source = (EnergySource)intent.getParcelableExtra("EXTRA_ENERGY");
  }
}

public class TimeTravelActivity extends Activity {

public String targetYear;

private NetworkConnectionReceiver receiver = new NetworkConnectionReceiver();

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_time_travel);

Intent intent = getIntent();

EnergySource source = (EnergySource)intent.getParcelableExtra("EXTRA_ENERGY");

}

@Override

    super.onResume();
   IntentFilter filter = new IntentFilter("android.net.conn.CONNECTIVITY_CHANGE");
  registerReceiver(receiver, filter);
}

 @Override
protected void onPause(){
    super.onPause();
}

If you created the intent filter in the previous challenge, it wont recognise it till now, so you can try and proceed to next task
