The default value is an integer. I try to use intent.getIntExtra to set the value of mFuelLevel but failed. Please help.
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 = getIntent();
mFuelLevel = intent.getIntExtra("FUEL_LEVEL");
}
}

12,851 PointsYou didn't close FUEL_LEVEL with "" from both sides ;)

7,421 PointsI tried to write
mFuelLevel = intent.getIntExtra("FUEL_LEVEL,-1);
it generated errors again..
./FlightActivity.java:14: error: unclosed string literal mFuelLevel = intent.getIntExtra("FUEL_LEVEL,-1); ^ ./FlightActivity.java:14: error: ';' expected mFuelLevel = intent.getIntExtra("FUEL_LEVEL,-1); ^ ./FlightActivity.java:16: error: reached end of file while parsing } ^ 3 errors

12,851 PointsSoo, you are using only one parameter: mFuelLevel = intent.getIntExtra("FUEL_LEVEL") instead as in docs: getIntExtra(String name, int defaultValue).
