4,007 PointsGetting Data from an Intent
My code looks right, but it shows this error message:
./FlightActivity.java:14: error: method getIntExtra in class Intent cannot be applied to given types;
Integer name = intent.getIntExtra("FUEL_LEVEL");
^
required: String,int
found: String
reason: actual and formal argument lists differ in length
1 error
And this is MY code:
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 bellow
Intent intent = getIntent();
Integer name = intent.getIntExtra("FUEL_LEVEL");
}
}

Treehouse TeacherAh, for Task 1 you just need the...
Intent intent = getIntent();
... line, that next line is the next step.

Judging by the error message it looks like you are on Task 2 where the instructions state:
Now set
mFuelLevelto the value from the Intent. Check the Intent documentation if you need help finding the correct
method to use. Use "FUEL_LEVEL" as the key and -1 as the default value.
In taking a look at the documentation for the method you chose, getIntExtra(), it takes a String and an int as parameters. Our task also wants us to set that value to mFuelLevel, not to an Integer named name.
Post back if you have further questions.
Happy coding,
Ken

4,007 PointsSame answer. Can you go to the top of this, and click on view challenge, copy my code and give it a try?
Peter Price

4,007 PointsThanks, but it says now:
./FlightActivity.java:14: error: cannot find symbol
Integer name = getIntExtra("FUEL_LEVEL");

symbol: method getIntExtra(String)
location: class FlightActivity

Treehouse TeacherFor Task 1 you should only have the:
Intent intent = getIntent();
line in the code challenge.

Treehouse TeacherMeaning for the part we add to the code.

4,007 PointsThank you so much for your help. I didn't take out the line underneath at first, and that's what was messing it up.
If you add an answer to me I will select it as "best answer".
