Cassowary Layout for Android released

[Alex Birkett]

Hi,

I've just pushed up my Cassowary layout for Android

https://github.com/alexbirkett/android-cassowary-layout

I started with Android's AbsoluteLayout class and added a Cassowary constraint parser inspired by https://github.com/anandsainath/constraint-layout (It first converts expressions from infix to postfix.)

There is a demo app (https://www.youtube.com/watch?v=_FYroNxqFqo&list=UUhNOwhSktPaby5zl3TehZBw)  but currently no documentation.

The performance is better than https://github.com/anandsainath/constraint-layout but I'd still like to improve it.

Cassowary layout for Android depends on my fork of Erwin Bolwidt's fork of cassowary.

Alan Borning and Greg Bradros gave me permission to use the Apache 2.0 licence for Cassowary on the condition that I released the Android Layout under the same licence. I've now done that :) Erwin Bolwidt also indicated that he would be prepared to release his changes under Apache 2.0 but wanted to see the emails from Alan and Greg. I've not yet got hold of his email address to forward them.

 I'd like to get a version of cassowary into maven central that just contains the core cassowary classes.  (No parsers, java gui code etc)  Erwin has not yet responded to my pull requests. If Erwin is otherwise occupied, perhaps Russell Keith-Magee and I should collaborate on getting Cassowary for Java into maven central?

Cheers,

Alex

This is super cool. Exciting to see another port!
