/README.md:
--------------------------------------------------------------------------------
1 | This repository hosts the coding exercises from a Kotlin Workshop for Android. Basic knowledge of
2 | both Android and Java is assumed for anyone participating in this workshop. No prior knowledge of
3 | Kotlin is required; the linked presentations, videos, and workbook start from very basic syntax
4 | in Kotlin and build from there.
5 |
6 | The linked presentations and videos are from a recording of a live event held internally at Yelp on
7 | May 24th, 2018, and may already be out of date. If a new event is held, this repository and its
8 | recordings may be updated. Otherwise, any updates are rather unlikely.
9 |
10 | ## Format of this Repository
11 |
12 | There are a total of 7 apps in this repository. If you follow along with the workshop, you can start
13 | from the folder `app` and build your Android app by following the instructions in the video and
14 | workbook. If you struggle to complete an exercise, you can simply look in the folder with the
15 | corresponding number. For example, `app4` contains the Android app that is the result of completing
16 | exercises 1-4. Alternatively, if you’re interested in completing, for example, only sessions 3 and
17 | 6, you can start from `app2` to complete the exercises in session 3, and then start from `app5` to
18 | complete the exercises in session 6.
19 |
20 | ## Format of the Workshop
21 |
22 | The workshop was intended as a one-day event. It was split into sessions of about 1 hour each. Each
23 | session roughly consisted of a 20-minute presentation, followed by a 20-minute live coding session,
24 | and finally, a 20-minute attendee coding session on a topic relevant to the presentation.
25 | Presenters were available during the coding sessions to answer questions or troubleshoot any issues.
26 | By the end of the day, we built a simple app that displayed a list of businesses using Yelp's public
27 | API.
28 |
29 | Here’s a [workbook][workbook] with more detailed information on the topic, and below is a list of
30 | all sessions and a brief summary of their content.
31 |
32 | ## Syllabus
33 |
34 | 1. Basic Syntax and Types - how to create classes, interfaces, and functions. At the end you should
35 | be able to write a very simple Kotlin class ([presentation][prezi1], [video][video1])
36 |
37 | 2. Constructors and Control Flow - difference between statements and expressions, conditional
38 | statements and loops, jumps and qualifiers, primary and secondary constructors, and execution flow
39 | when constructing instances ([presentation][prezi2], [video][video2])
40 |
41 | 3. Functions - operators, inlining, a little bit about generics, named parameters, lambdas and
42 | closures, obtaining references to functions and passing them to other functions, and higher-order
43 | functions ([presentation][prezi3], [video][video3])
44 |
45 | 4. Properties and Nullability - Java interop, synthetic and delegated properties, custom setters and
46 | getters, `lateinit`, nullable and non-null properties, and optional invocation
47 | ([presentation][prezi4], [video][video4])
48 |
49 | 5. Useful Kotlin Standard Functions - introduction to `use`, `let`, `apply`, `also`, `with`,
50 | `isEmpty`, `orEmpty`, and more, as well as how and when to use them ([presentation][prezi5],
51 | [video][video5])
52 |
53 | 6. Kotlin's Collections APIs - mapping, transforming, filtering, aggregating, and associating
54 | anything you can iterate over like a boss ([presentation][prezi6], [video][video6])
55 |
56 | 7. How to Build DSLs - what they’re useful for and how to build them ([presentation][prezi7],
57 | [video][video7])

157 | liable to You for damages, including any direct, indirect, special,
158 | incidental, or consequential damages of any character arising as a
