Cannot pass custom Object in an Intent: The Method Put Extra is Ambiguous for the type Intent

问题:

If I try to write

Car myCarObject=getCar(); Intent details = new Intent(Start.this, DetailsCar.class);                 details.putExtra("Car", myCarObject);                 startActivity(details);

Eclipse show me a compilation error "The Method Put Extra is Ambiguous for the type Intent" in the line

  details.putExtra("Car", myCarObject);

If I use the code

Car myCarObject=getCar(); ArrayList parcelableExtra = new ArrayList();                 parcelableExtra.add(myCarObject);  Intent details = new Intent(Start.this, DetailsCar.class);                 details.putExtra("Car", parcelableExtra);                 startActivity(dettagli);

And I try to load the extra with this code in the destination Intent with

ArrayList parcelableExtra = new ArrayList();         parcelableExtra = (ArrayList) getIntent().getExtras().getParcelable("Car");         Car c=parcelableExtra.get(0);

I get this warning
