We've updated our LaunchActivity to include a fuel level (mFuelLevel) for the spacecraft. This value needs to be passed to the FlightActivity. Add the code to pass this value along via the Intent. Use the key "FUEL_LEVEL".
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class LaunchActivity extends Activity {
public Button mLaunchButton;
public int mFuelLevel;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_launch);
// mFuelLevel is set elsewhere.
// Code ommitted for brevity!
mLaunchButton = (Button)findViewById(R.id.launchButton);
mLaunchButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Add your code in here!
Intent intent = new Intent(LaunchActivity.this, FlightActivity.class);
intent.putExtra(" mFuelLevel", mFuelLevel);
startActivity(intent);
}
});
}
}

intent.putExtra("FUEL_LEVEL", mFuelLevel);

intent.putExtra("FUEL_LEVEL", fuelLevel);
Don't forget Java is case sensitive.
