Utility methods for a class? Add them to the top level of the source file. In Java, they are compiled as static methods of that class.

Are you defining static constants for your class? Make them top-level properties. They will be compiled to a field and static accessor(s).

There are similar patterns to the top challenges game developers experience, regardless of the size of their games business. In this post Saikala Sultanova (Director of User Acquisition at Ubisoft) shares how to overcome three of these challenges: goal setting, acquisition intelligence and soft launches.

Write Kotlin (time * 2) faster with operator overloading. Objects like Path, Range or SpannableStrings naturally allow for operations like addition or subtraction. With Kotlin, you can implement your own operators.

Activity Recognition's new Transition API makes context-aware features accessible to all developers

Read the full blog post → goo.gl/5QDeaj

Phones are our most personal devices we bring with us everywhere, but until now it's been hard for apps to adjust their experience to a user's continually changing environment and activity. We've heard from developer after developer that they're spending valuable engineering time to combine various signals like location and sensor data just to determine when the user has started or ended an activity like walking or driving. Even worse, when apps are independently and continuously checking for changes in user activity, battery life suffers. That's why today, we're excited to make the Activity Recognition Transition API available to all Android developers - a simple API that does all the processing for you and just tells you what you actually care about: when a user's activity has changed.

Introduction to Wear OS Application Development

Wear OS by Google (Formerly Android Wear) is based on Android. As a result, the concepts and tools you use for Android Development are applicable for Wear OS. That being said, Wear OS is a different form factor. This video runs through the main design and development tips for developing Wear OS Apps.

Sequences are lists that never existed. A Sequence is a cousin of Iterator, lazily generating one value at a time. This really matters when using map and filter - they’ll create Sequences instead of copying the list for every step!

Docs: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.sequences/index.html

You can make sequences from a list or by specifying a next function. If you never terminate a sequence, it can be infinitely long without running out of memory. With coroutines in Kotlin you can also use generators!
