There is no getExtraString() method in the Intent class. There is getStringExtra() but that is not useful here because the value we are getting from the intent is an int, so use getIntExtra() instead. You need to pass the key "FUEL_LEVEL" and a default int value of -1 to the method. Also, you need to assign the retrieved value to mFuelLevel.
