Exceptions are useful if you use them properly. If you don't use them properly, you will be ridiculed and write bad code. We'll demonstrate how to handle exceptions correctly by showing some ways NOT to handle exceptions and how you can improve your exception handling.

RxJava has many uses, especially for applications requiring any amount of asynchronous operations. If you do not have experience with RxJava (or any of its sister implementations), I recommend checking it out and seeing if it can help improve your applications. I will not be covering the basics of RxJava in this blog, so a familiarity with the core concepts is recommended. In this blog I will be covering how to create a simple bus implementation using RxJava in a pure Java application. This implementation can be ported to other Java-based platforms, such as Android. There are a few particulars I will cover before jumping into the implementation.

At the Google Nexus event today, Google's CEO and others from their leadership team unveiled several new and improved products as well as launched the new Android 6.0 update named Marshmallow. They made sure everyone understood that the ubiquity of Google and their products was only going to become more profound with the passage of time.

Android M has officially been revealed to be Android Marshmallow, version 6.0. Among a number of improvements and changes are permissions. Previously, permissions were required to be accepted by the user before installing the app, and they could never be revoked. This meant that the only way to prevent an app from accessing something it requested was to not use the app. The new setup instead gives users granular control over which permissions are allowed on a per app basis.

In the past few development posts, Ron has given us insight into several aspects of Android unit testing. He began with an overview of unit testing concepts and then discussed JUnit, the framework that Android testing is built upon. Today, he rounds out the series with an article on some specific Android libraries that can make unit testing a whole lot easier.
