![]() Take your application big-time with full Internet web services without having to become a server admin by leveraging the power of Backend as a Service (BaaS) providers. We'll also demonstrate Google Maps and Google Cloud Messaging (also known as Push Notifications) using the Google API Library.įinally, we'll take a look at several online services designed especially for Android development. Then we move on more advanced topics such as graphics and animation (including OpenGL), multi-threading with AsyncTask, and Internet functionality with Volley. ![]() From there, we cover fragments and data storage (including SQLite), device sensors, the camera, and GPS. The first few chapters cover the basics including Activities, Layouts, Widgets, and the Menu. Starting with the basics of Android development, we move on to more advanced concepts, and we'll guide you through common tasks developers struggle to solve. If you are new to Android and learn best by “doing,” then this book will provide many topics of interest. This “cookbook” will make it easy for you to jump to a topic of interest and get what you need to implement the feature in your own application.
