I have a class which has implemented Parcelable. Can I do something like the following to create a new instance of a class?:

Foo foo = new Foo(\"a\", \"b\", \"c\

    I had the same problem and here is my solution:

    Parcel p = Parcel.obtain();
    foo.writeToParcel(p, 0);
    p.setDataPosition(0); // <-- this is the key
    Foo foo2 = Foo.CREATOR.createFromParcel(p);
    p.recycle();
