31,298 PointsIntents and Broadcast Receivers Challenge Task Error
The questions says: Now we need to retrieve the new extra in TimeTravelActivity. Add an EnergySource variable and set it to the extra from the Intent. The error I'm getting is this:
./TimeTravelActivity.java:15: error: incompatible types: Parcelable cannot be converted to EnergySource
EnergySource source = intent.getParcelableExtra("EXTRA_ENERGY");
^
1 error
The previous question clearly says that the EnergySource implements the Parcelable interface. If that was true, then why I'm getting this error?

// Add your code in here!
Intent intent = new Intent(MainActivity.this, TimeTravelActivity.class);
