I'm studying Kotlin, and I thought this site would be an excellent place to share things that I've learned and hopefully help someone that is on the same journey. In this blog post, I'll explain what is Kotlin and review some of the few nice features of the language, and we'll create a Hello World Android app using Kotlin. Let's get started. What is Kotlin? Kotlin is a new programming language created by JetBrains that targets Java platform. Kotlin is: - Concise: Kotlin syntax clearly expresses the intent of the code you read and doesn't obscure it with boilerplate code. -Pragmatic: Kotlin is a useful language intended to solve problems real-world problems. -Interoperable: Kotlin can work with Java seamlessly. No tricks required: Kotlin classes and methods can be called exactly like regular Java classes and methods. The IDE provides full support for cross-language projects. Making it easy to navigate freely between Java and Kotlin source f...

Today I updated my Mac to OS Sierra, and when I opened Android Studio, I was getting an error about Git configuration So I went to Preferences/Git, and I make sure the path to git executable was working by clicking on the Test button, and that's when I got this error :  xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun I figure I'd post this in case someone else runs into the same situation. The solution:  xcode-select --install Happy coding!

I've been looking forward to this moment for the past month. I've finally released the first version of my Android app to keep your ideas organized and always available.  With this app, I wanted to showcase how easy is to develop an Android app implementing the new Android Architecture Components and Material Design guidelines using only Kotlin as a programming language. I will share in the next posts the lessons I've learned creating this app.  My goal is to create tech products that can help others; there are a ton of features in the works and will be available soon. I also have plans to start building this app for other platforms such as iOS, Google Actions, and Alexa Skills.  I'll leave here a screenshot of the first version of Next Idea app for Android and the link to the Google Play Store Listing page. 

A quick guide to creating an easy to read report of your dependency tree using Gradle.  Inspecting Dependencies  Gradle provides enough tools to navigate large dependency graphs and solve situations that can lead to  dependency hell . You can choose to render the full graph of dependencies as well as identify the selection reason and origin for a dependency. Listing dependencies in your project Rendering the dependency tree is particularly useful if you'd like to identify which dependencies have been resolved at runtime and get valuable information in case any dependency conflict resolution occurred. The dependency report will contain declared and transitive dependencies. Every Gradle project provides the task dependencies for rendering the so-called dependency report from the command line. By default, the dependency report presents dependencies for all configurations. To print information for a specific configuration, you need to provide the optional paramete...

Hi, welcome to my blog. I'm going to use this space to write about how to build Android apps and share my background and some lessons learned for the past 4 years working as an Android developer. Software development is growing very fast, with tons of new languages, frameworks, components released so, we the developers have to be up to date and take advantage of the latest technologies and tools if we want to succeed. That is my goal with this project to help people out there trying to come into this space. If you are new to Android development you come to the right place. Stay tuned, in my first blog series I'll be writing about Kotlin for Android Development and I'll teach you how to build your first app. I am very excited to start this journey and be able to connect with you. I want to know what your next app idea is. Leave a comment down below and don't forget to hit the subscribe button. I'll leave here a picture of me back in 2016 at the G...
