Using Icepick without Annotation Processing?

[mazurio]

Hi,

Is it possible to use Icepick without "@State" annotations? Can I manually add the objects I want to save? I would like to use Icepick with Kotlin but I cannot get it to work.

Thanks

I'd love to use kotlin too, but when you have Icepick

a simple class as

abstract class BaseFragment : Fragment() {

    override fun onCreateView(inflater: LayoutInflater?, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        return super.onCreateView(inflater, container, savedInstanceState)
    }

}

fails to compile because of icepick processor.

not really sure tough if it's the kotlin processor or icepick.

If you're not a fan of exposing your variables and using @JvmField, I've started a simple lib that should work as Icepick: https://github.com/tinsukE/icekick
Contributions are welcome!

[adrielcafe]

@tinsukE your lib works great! Thanks man!

And here's another alternative. Same API like Icepick, but works well with properties: https://github.com/evernote/android-state
