LandingActivity.java
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class LandingActivity extends Activity {

    public Button mThrustButton;
    public TextView mTypeLabel;
    public EditText mPassengersField;

    public Spaceship mSpaceship;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_landing);
        mThrustButton = (Button)findViewById(R.id.thrustButton);
        mTypeLabel = (TextView)findViewById(R.id.typeTextView);
        mPassengersField = (EditText)findViewById(R.id.passengersEditText);
      mSpaceship  = new Spaceship ("FIREFLY");
       mTypeLabel.setText(mSpaceship.getType());

   mPassengersField.setText(mSpaceship.getNumPassengers());

        // Add your code here!
    }
}
Spaceship.java
public class Spaceship {
    private String mType;
    private int mNumPassengers = 0;

    public String getType() {
      return mType;
    }

    public void setType(String type) {
      mType = type;
    }

    public int getNumPassengers() {
      return mNumPassengers;
    }

    public void setNumPassengers(int numPassengers) {
      mNumPassengers = numPassengers;
    }

    public Spaceship() {
      mType = "SHUTTLE";
    }

    public Spaceship(String type) {
      mType = type;
    }
}

you need to turn the int into a String.

mPassengersField.setText(mSpaceship.getNumPassengers() + "");

It look like it wants the number of passengers as a string but right now your returning a number. Try doing:

public int getNumPassengers() {
      return mNumPassengers.toString();
    }

it's say:./Spaceship.java:15: error: int cannot be dereferenced return mNumPassengers.toString(); ^ 1 error
