What is context-aware mobile application?
Context-aware mobile applications are systems that can sense clues about the situational environment and enable appropriate mechanisms of interaction between end users and systems, making mobile devices more intelligent, adaptive, and personalized.
What is context service on my Android phone?
Dubbed Context, the service monitors everything the user does on the mobile device, including text input, app usage, and even information from the phone’s sensors.
What are major sources in development of context-aware application?
Web browsers, cameras, microphones and Global Positioning Satellite (GPS) receivers and sensors are all potential sources of data for context-aware computing. A context-aware system may gather data through these and other sources and respond according to pre-established rules or through computational intelligence.
What is the difference between activity and context?
In android, context is the main important concept and the wrong usage of it leads to memory leakage. Activity refers to an individual screen and Application refers to the whole app and both extend the context class.
What is the difference between application context and activity context?
Application Context: It is the application and we are present in Application. For example – MyApplication(which extends Application class). It is an instance of MyApplication only. Activity Context: It is the activity and we are present in Activity.
What is context-aware system in mobile computing?
Context-aware computing describes the situation where a wearable/mobile computer is aware of its user’s state and surroundings and modifies its behavior based on this information.
Why do you need context-aware computing in mobile computing?
When we aim to create applications, devices, and systems that are easy to use, it is essential to understand the context of use. With context-aware computing, we now have the means of considering the situation of use not only in the design process, but in real time while the device is in use.
How can we improve the testing of context-aware mobile applications?
Griebe and Gruhn [ 44] propose a model-based approach to improve the testing of context-aware mobile applications. Their approach is based on a four-tier process system as follows: Tier 1: UML activity diagrams models are enriched with context information using a UML profile developed for integrating context information into UML models;
What is a contextaware class in Android?
The class representing a car app activity. Base class for activities that want to use the support-based Fragments. A ContextAware class is associated with a Context sometime after the class is instantiated. By adding a OnContextAvailableListener, you can receive a callback for that event.
What is a framework for building and operating context-aware mobile applications?
“A Framework for Building and Operating Context-Aware Mobile Applications” [ 113 ]: presents a work-in-progress paper with the description of a framework architecture design to address the following context-aware mobile applications problems: interoperability, dynamic adaptability, and context handling in a frequently changing environment. 25.
How do I get a callback for a contextaware event?
A ContextAware class is associated with a Context sometime after the class is instantiated. By adding a OnContextAvailableListener, you can receive a callback for that event.
