Talks:
>> Let's convert the I/O Sched app to Kotlin, by Brent Watson
All of the talks you've probably seen on Kotlin have likely been language tours. So you're sold on Kotlin, but how do you get started? Where are the sharp corners? How do compile and run times compare after a conversion? This is going to be a very pragmatic talk where we actually covert parts ofhttps://github.com/google/ioschedfrom Java to Kotlin and compare the before & after. May the demo gods be with us all.

>> Practical GraphQL for Android, by Kevin Schultz
Native mobile apps require a significant ongoing investment in building APIs. Most apps use REST style APIs that require matching client & server data models. Change is tedious and error-prone. Versioned endpoints must remain indefinitely. This leads to product stagnation and a resistance to evolving APIs to better suit product needs. GraphQL was designed specifically to address these issues. Facebook has used GraphQL since 2012 and it has proven to be a more productive paradigm than REST. GraphQL is an open specification that defines a declarative, compositional, strongly-typed language for data-fetching APIs. Facebook has released an open source reference implementation written in JavaScript. Community built open source libraries exist for Java, PHP, Python, Ruby, Go and more. This talk will walk through usage of GraphQL in an Android app. No previous GraphQL experience is expected.

Many thanks to our October sponsor, Facebook, for making this event possible. Special thanks to Huy, Greg and Ciara for coordinating.
