Publish multi-module Android libraries on JitPack

in 👨‍💻 Dev

If you’re an Android developer and learned to love the benefits of open source, you may want to publish you’re own libraries sometime. A common used services for building and providing Android libraries is JitPack. It’s a user friendly alternative to jCenter, which takes a lot of pain from the process of publishing a library. It’s as simple as adding a few lines of code to your project. Now, given the case, that you already have an open source Android app, where you developed some special features (that may be helpful for other developers too), you don’t want the other developers needing to copy parts of your app.

I’m into Kotlin, because it’s a new (quite new) programming language, that solves all the Java problems, especially on Android. You can simply use Lambda expressions and much more on any API version. I also used Kotlin in production in my open sourced newsreader app NewsCatchr. Here I’ll share some of the sources, that helped me getting some knowledge in Kotlin: The documentation The documentation is a really helpful source. I learned Kotlin myself through practice and every time I didn’t understand something I went looking in the docs and they already answered most of my questions, for example how to use any of the many helper functions in the standard library.

Great Open Source Android Libraries

in 👨‍💻 Dev

Libraries are a bunch of code that simplifies developing of certain features and prevent you from reinventing the wheel. Because most Android libraries are open source it’s also possible to fork and modify them. But you should take care about the specific licenses. I’ll present you some more popular, but also some not so popular libraries. But all of them are usable for many different purposes. 1. Material Dialogs A beautiful, fluid, and customizable dialogs API.
