Google is making their development tools even better, with Android Studio getting a bump up to version 1.3, and Polymer going official with version 1.0.
On the stage at Google I/O 2015, Google introduced a large update to Android Studio, made Polymer official, and introduced Cloud Test Lab. With all of these new tools, Google has improved the developer experience, giving them better tools to get the job done. Included in the updated tools is faster gradle build speeds, along with a new memory profiler. Developers will have full C/C++ debugging, the same IDE as found in Canary. The Polymer library for browsers and mobile adds new elements like menus, maps, toolbars, and more.
Google has also rolled out a Cloud Test Lab, which is the result of the Appurify acquisition. This allows developers to upload an app and it is then tested on 20 popular Android devices, without having to do the work yourself. Cloud Messaging has expanded beyond just Android and Chrome, as it now supports iOS as well. Topic subscriptions allow a user to subscribe, receive a notification from an app that is sent by Google cloud.
Finally, Google is making some big changes to the developer console as well. With these new changes developers will be able to see how many users are seeing their app, purchasing and installing it, and even where they are coming from. Additionally developers can A-B test different graphics and text in their listings to see what users prefer. Google has also created developer homepages, to which developers can upload custom graphics to, feature their popular app, and make it look much nicer than just a list of apps they have created. New analytics will also reveal how users are using the app, see how long it takes for users to complete a level, and allow developers to pop-up a prompt for an in-app purchase or add if it is taking them too long.
