Hello. I used this method: mFuelLevel = intent.getIntExtra("FUEL_LEVEL", 0);
What did I do wrong?
With respect, Aleksandr.
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 = new Intent();
mFuelLevel = intent.getIntExtra("FUEL_LEVEL", 0);
}
}

1,632 PointsYou need to get the intent that was used to start the current activity. i.e.
// instead of this . .
Intent intent = new Intent();
// do this . .
Intent intent = getIntent();
Also, make sure you are passing the correct default value to getIntExtra().

2,158 PointsYou won't be able to get any extras from your intent because you just declared it as a new Intent on the line above. What are you trying to accomplish? Are you trying to create an intent to open a new Activity or possibly broadcast out for broadcast receivers to pick up? Or are you trying to store the fuel level out to disk and then retrieve it when FlightActivity is created?
