Android Libraries that can clean up your code (with examples)!

Android development is fun there’s no doubt about it! But there is also a lot of repetitive boilerplate code that the platform forces us to write. Quite a lot of it is related to the UI components that you need to process. Some of it is required when you want your application architecture to be clean. There are a lot of operations executing asynchronously in the background – in fact, it’s quite easy to end up with a bunch of spaghetti code that is unreadable or just does not feel right.

Today we’ll look at 7 Android libraries that help you keep your code clean and readable, using an example project so that you can see the libraries in action.

Using build cache in Android Studio makes Gradle build faster

We have previously published articles that, surprisingly, are not about JRebel for Android, but are useful for every Android developer. We’ve talked about your Gradle build times, about getting started with Retrofit 2 and so on.

Today, I’ll take a look at build cache that is coming to Android development toolbelt in the future. This can potentially have a great impact on improving build times. Which is universally a good thing, since no one likes to spend more time waiting for the project to build.

How to mock up your Unit Test environment

Not long ago, I inherited a bunch of spaghetti code sitting inside a big legacy enterprise application, and I found myself hoping that everything I needed to deal with was already there (and hopefully working properly). But when I needed to change something, how could I tell what will be affected? The side effects of any changes I make should be clear from the beginning. If only I could do unit tests AND see the ripple effect across the code too…

Well, I can. It’s called Mocking, and it lets you create alternative realities for your application to play through, without having any side effects or consequences in reality.
