Help with FlightActivity.java

Tried all these, still got a problem

   // intent.getIntExtra ("FUEL_LEVEL", -1);
   // Intent intent = getIntent();
   // intent.putExtra("FUEL_LEVEL", mFuelLevel);
   // startActivity (intent);
    // mFuelLevel = intent.getIntExtra("FUEL_LEVEL", -1);
    // Intent intent = getIntent();
   // intent.putExtra("FUEL_LEVEL", mFuelLevel);
FlightActivity.java 
import android.os.Bundle;

public class FlightActivity extends Activity {

  public int mFuelLevel = 0;
  public String 
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_flight);

    // Add your code below!
    Intent = intent = new Intent();
        intent.getIntExtra("FUEL_LEVEL", -1);
        Intent intent = getIntent();
        intent.putExtra("FUEL_LEVEL", mFuelLevel);
        startActivity(intent);

  }
}

// I solved it!

import android.os.Bundle;

public class FlightActivity extends Activity {

public int mFuelLevel = 0;

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

// Add your code below!
Intent intent = getIntent();
startActivity (intent);

} }

You have the two correct lines in there:

// Gets the Intent that started this Activity
Intent intent = getIntent();
// Get the value passed in with the Intent, use
// -1 as the fall back value in case it wasn't sent in.
mFuelLevel = intent.getIntExtra("FUEL_LEVEL", -1);

You just needed to assign the result of getIntExtra to mFuelLevel
