Last year, the designers at Vitamins, a design studio in London, took some time to build something for themselves. What they needed was a way to keep track of all their various projects. It had to be big and visual and easy to use in person but also accessible online. Their solution? A wall-sized calendar made entirely of Lego bricks that syncs with Google automatically via smartphone screenshots. Wired

MockServer can be used for mocking any system you integrate with via HTTP or HTTPS (i.e. services, web sites, apps , etc). MockServer can: return a "mock" response when a request matches an expectation forward a request when the request matches an expectation (i.e. a dynamic port forwarding proxy) execute a callback when a request matches an expectation, allowing the response to be created dynamically verify requests have been sent (i.e. as a test assertion) MockServer

A memory leak detection library for Android and Java. “A small leak will sink a great ship.” - Benjamin Franklin LeakCanary will automatically show a notification when an activity memory leak is detected in your debug build. GitHub / LeakCanary

Introduction to Android Espresso Testing and Spoon Espresso UI test automation framework is Google’s de-facto testing platform for Android app developers. No test engineer or developer will be quite unless it validates the functionality of his app on multiple devices and emulators. For that, there is another widely used tool called Spoon (there are also cloud-based solutions as mentioned above that support parallel execution on real devices). This tool, will collect all the target devices (that are visible via adb devices) test results and aggregate them into one HTML view that can be easily investigated. Mobile Testing Blog Android Test Sharding The test runner supports splitting a single test suite into multiple shards, so you can easily run tests belonging to the same shard together as a group, under the same Instrumentation instance. Each shard is identified by an index number. When running tests, use the -e numShards option to specify the number of separate shards to cr...

Firebase Remote Config is a cloud service that lets you change the behavior and appearance of your app without requiring users to download an app update. When using Remote Config, you create in-app default values that control the behavior and appearance of your app. Then, you can later use the Firebase console to override in-app default values for all app users or for segments of your user base. Your app controls when updates are applied, and it can frequently check for updates and apply them with a negligible impact on performance. Firebase Remote Config

Introducing Firebase Performance Monitoring Monitoring performance from the end user's point of view - both app code performance and network responsiveness/reliability - is a challenge for building great mobile apps. You have to be able to understand conditions that need improvement, in order to avoid user churn and negative reviews. Conversely, we have seen that 60% of 5-star reviews on Google Play mention speed, design or usability. This is why we built Firebase Performance Monitoring for iOS and Android. It provides an SDK to capture and instrument performance metrics in production, and a console to gain insights about the data captured by the SDK.
