As humans, we have emotions and feelings and one of the best ways to capture our emotions is to take pictures.
Some of our greatest experiences are actually captured in pictures. For sure each one of us have pictures from birthday parties, holidays, travels, conferences. We also like capturing feelings like happiness or reactions when bad surprises happen. And, in the latest years, we discovered that we love taking selfies.
Last year, Google invited developers to submit their ideas for the Android Developer Challenge, focused on “Helpful Innovation, powered by on-device machine learning.” They picked 10 winners, and have been working with them since then to help bring their apps to life. #AndroidDevChallenge
Generics means we use a class or an implementation in a very generic manner. For example the interface List allows us for code reuse. We are able to create a list of Strings, of integer values and we will have the same operations even if we have different types. So the list wraps a common functionality for each implementation.
Kotlin allows you to use parameters for methods and attributes, composing what is known as parameterized classes.
I recently presented this talk at mDevCamp – Online edition. More than that I was part of a Virtual 3D world. Great event, awesome organizers and really interesting questions from the audience.
This talk contains the answers for the next questions:
I recently presented this talk at DevTalks Reimagined – Online Edition. This talks contains the answers for the next questions:
An Android app could contain one or many activities. An activity has its own lifecycle and we can launch a new activity by using intents. In order to send data from an activity to another we could use a Bundle.
Coroutines are officially part of the Kotlin standard library starting with version 1.3 and they are very helpful in creating concurrent non-blocking code. They simplify async programming. Coroutines are actually lightweight threads.
It’s time to continue our learning path in Kotlin. The subject covered in this new post is represented by Collections and data operations applied to them.
Collections are actually a set of classes and interfaces that provides high quality implementations of useful data structures and algorithms that help developers to reduce the programming effort and time.
The journey in Kotlin Wonderland continues with an article about classes and objects. Until now we discovered details about Kotlin philosophy, basic types, control flow expressions, null safety and functions.
Kotlin promises concise, expressive and safe code. In the previous articles I covered topics like basic types, control flow instructions, equality checks, null safety.
In this article we will have some fun with functions and learn new keywords from the Kotlin Wonderland.
