In greenrobot is all about Android and app development. Even before launch, we began in 2007 to develop for Android. With this experience, we know that more than any other platform. Small and large customers such as Media Markt, and E-Plus Group Scout24 rely on our know-how when it comes to the development of Android apps. In addition, we regularly write articles for magazines, speak at conferences, organize events, and developers operate open source projects.
