I don't understand what is to be done here.

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 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");
}

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

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

Hi there, Tojo Alex ! It looks to me like you're doing pretty well. You've clearly understood that we need to unregister the receiver but there are some capitalization and spelling errors in that line. The receiver is not named mReceiver, but rather just receiver so you should be getting an error about an unresolved symbol. Also, the the first "R" in "unregister" should not be capitalized. You also have a very common spelling error in both where you're putting the "i" before the "e". It's "receiver" as opposed to "reciever". Take a look at the line I used:

unregisterReceiver(receiver);

Hope this helps! :sparkles:
