Peter Späth · Apress eBooks · 2018
An Android app consists of components such as activities , services , broadcast receivers , and content providers , as shown in Figure 2-1. Activities are for interacting with device users, services are for program parts that run without a dedicated user interface, broadcast receivers listen for standardized messages from other apps and components, and content providers allow other apps and components to access a certain amount and kind of data provided by a component. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
