This is the error that I keep getting
./FlightActivity.java:14: error: cannot find symbol String name = intent.getStringExtra("fuelLevel"); ^ symbol: method getStringExtra(String) location: variable intent of type Intent ./FlightActivity.java:15: error: cannot find symbol Log.d(TAG,name); ^ symbol: variable TAG location: class FlightActivity ./FlightActivity.java:15: error: cannot find symbol Log.d(TAG,name); ^ symbol: variable Log location: class FlightActivity 3 errors
import android.os.Bundle;
public class FlightActivity extends AppCompatActivity {
public int fuelLevel = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_flight);
// Add your code below!
Intent intent = getIntent();
String name = intent.getStringExtra("fuelLevel");
Log.d(TAG,name);
}
}

so the : String name = intent.getStringExtra("fuelLevel"); its false the right is : fuelLevel = intent.getIntExtra("FUEL_LEVEL", -1);
also you don't must write : Log.d(TAG,name); because the exercise don't ask about this
import android.os.Bundle;
public class FlightActivity extends AppCompatActivity {
public int fuelLevel = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_flight);
// Add your code below!
Intent intent = getIntent();
fuelLevel = intent.getIntExtra("FUEL_LEVEL", -1);
}
}
:)

8,155 PointsI didn't get it , I choose this default value ,, so if the value from "extras" is null then set the fuelLevel with this default value .
Actually when a string has no value then return null ,, when a int has no value then return -1 .. play with that open the android studio with a new project and write for example ….
int a; string b; (with no values) then write …
Log.d(TAG,a); Log.d(TAG,b);
and check at the logcat what the empty integers , strings , etc. that returns :)
