Support for String arrays

[littledot]

I declared a class that has a String array property.

@AutoParcel
public abstract class Foo implements Parcelable {
    abstract String[] bar();
}

However, the compiler throws:

An @AutoParcel class cannot define an array-valued property unless it is a primitive array

Is there any reason to not have support for String arrays?

To ensure immutability of the underlying class and consistency of the hashcode and equality checks, AutoValue rejects any array that is not a primitive type. It is a pessimistic behaviour and Strings are immutable, so it should work with it. However, Java arrays are fundamentally broken and I would discourage their use in any case. But if you feel like that's something they should add you can open an issue upstream: https://github.com/google/auto/issues

Closing because auto-value will not support object arrays.

Object arrays are not and will not be supported, including multidimensional primitive array types. Use a Collection type instead, such as ImmutableList.
