Anyone can find the error? Compiler imputes the error at line 17, it seems it doesn't like the parenthesis of the getParcelableExtra...why?!

I miss casting source
when I retrieve it from the intent.
It has to be like:
energySource = (EnergySource) intent.getParcelableExtra(MainActivity.EXTRA_ENERGY);
