This document discusses intents and intent filters in Android. Intents allow activities to start other activities or services and intent filters define the types of intents an application component will respond to. The manifest file is used to declare intent filters for activities and services so they can be started by implicit intents that match the declared filters.
This document discusses Android dialogs and provides information on how to create, prepare, show, and dismiss them. It notes that dialogs require a unique ID and that the onCreateDialog and onPrepareDialog methods are used to define dialogs by ID, while showDialog displays them and dismissDialog or dismiss removes them from the screen.
This document provides links and information about various Android components including Handler, AsyncTask, IntentService, Service, and broadcasting Intents. It discusses starting and binding Services, using AIDL for cross-process communication, and receiving broadcasts in an Activity or Service.
This document discusses a developer collaboration project between Okinawa and Sumsung on Android applications. It mentions the Okinawa Software Consortium conference in 2010, a JAG developer, and a link to information on a developer collaboration project using Java on mobile devices like the Samsung Galaxy S.
This document summarizes how to create and use services in Android. A service can run in the background indefinitely, and does not provide a user interface. Services can be started with startService and allow interaction through binding. Services communicate with broadcast receivers to deliver results or messages. Binding to a service returns an IBinder interface to directly call service methods, while broadcasts allow loosely coupled communication through intent filters and messages. Services should be stopped or unbound when no longer needed to prevent wasting resources.
This document provides updates on several projects including ABC launching a new long-term project and releasing a new product called GClue. It also mentions WEB+DB Press launching a new website and JAG starting a new initiative and website. Several links are provided for further information.
WebView allows Android applications to display web content. It uses the WebKit rendering engine and can load webpages via a URL or local assets. JavaScript can be enabled to allow interaction between the application and web content. The manifest must define required permissions and WebView methods like loadUrl are used to display webpages within the application. JavaScript interfaces can also be defined to expose application functions to webviews.
The document discusses key concepts in Android user interface development including activities, views, view groups, layouts, common widgets like text views and buttons, setting click listeners, displaying dialogs and menus. It provides examples of how to create basic buttons and listen for clicks, as well as links to further tutorials on related UI topics.
