Google have recently launched an open source collection of sample Android Applications under the name ‘Apps For Android’.
The aim for Apps For Android is to share some sample applications that will help to demonstrate the different aspects and possibilities of the Android platform.
The first available application included is called Wikinotes, “a wiki note pad that uses intents to navigate to wiki words and other rich content stored in the notes.”
WikiNotes for Android was written to demonstrate a number of core concepts in Android, including:
* Multiple Activities in an Application (View, Edit, Search, etc.)
* Default intent filters for View/Edit/Search based on MIME types
* Life cycle of Activities
* Message passing via Bundles in Intents
* Use of Linkify to add Intent-firing links to text data
* Using Intents within an application
* Using Intents to use an Activity within another application
* Writing a custom ContentProvider that implements search by note title
* Registration of ReST-like URIs to match titles, and do contents searches
* SQLite implementations for insert, retrieve, update, delete and search
* UI layout and creation for multiple activities
* Menus and keyboard shortcuts
