Back in July, we took a look at Testdroid, a service that allows developers to test their application or game on over 250 different actual devices. This isn't an emulation service – every single test is performed on real Android-powered devices, which in turn exposes real problems. Some of the biggest names in the book are using Testdroid these days – Facebook, Swiftkey, Rovio, Pinterest, Paypal, and many others – so it's only natural that the company step up its game to keep customers happy.
The life of a mobile application developer is a tedious one – they're not only responsible for building apps but also ensuring they work on as many of the 900 million Google-certified Android devices that have been activated over the last five years as possible. Of course, Android OS versions start to die out over time, and new versions – along with new handsets – emerge, making this a never-ending cycle of test-update-test-update.
