# A tiered light indicator is pretty easy to build and this will show you how to build scalable indicators using (2n + 1) decoders 
# and one arithmetic. I made mine with three lights, which is enough to understand at a glance what's going on.
# 
# You can also put the logic on the lights and use fewer deciders but I prefer this setup because it's easier to modify.
# 
# Inputs: 
#   - R is a constant "ratio". It should be set to the integer value of (tank size - 1 / # of lights).
#   - resource types
#
# Variables:

// In the following declaration, what happens when you call fn()?

val fn: () -> Unit = { "I am not a string" }

// Due to inference, the lambda is evaluated to return Unit and the string is discarded. It is as if you typed,

fun fn(): Unit {
  "I am not a string"
  return

To use EmojiCompat, initialize the library when the application starts by using downloadable or bundled fonts. Start supporting emojis in your text views, either by integrating the provided widgets or update your custom views by using the provided helper classes. \n\nFor more information:\nEmojiCompat guide → https://goo.gl/7bEoXB \nEmojiCompat sample app → https://goo.gl/7bEoXB \nGoogle I/O 2017 talk on “What’s new in Support Library” → https://goo.gl/KeRvqB\n\nWatch more Android Jetpack videos here → https://goo.gl/kw8LPv\n\nSubscribe to the Android Developers channel here → https://goo.gl/vLYDU\n\n#jetpack #featured","url":"https://www.youtube.com/watch?v=sYGKUtM2ga8","updated":"2018-06-07T17:09:43+00:00","thumbnail":"https://i4.ytimg.com/vi/sYGKUtM2ga8/hqdefaul
