Hi All, Here is updated version of the Intent to Implement:
Description: This implemented W3C Contacts Manager API on Android Affected component: runtime/android/java/src/org/xwalk/runtime/extension/api Related feature: XWALK-49<https://crosswalk-project.org/jira/browse/XWALK-49> Target Release: Crosswalk-3 Target Platform: Android Implementation details: Spec: http://www.w3.org/2012/sysapps/contacts-manager-api/ Summary: This API is designed as an internal extension inherited from XWalkExtension. Status of the Spec: The outstanding question since the last F2F (August) is whether to use DataStore API for Contacts and Messaging (and CallHistory): https://wiki.mozilla.org/WebAPI/DataStore Support from other venders: AFAIK Firefox Mobile(Gecko) supports this API since 18.0 Not supported on Android, Opera, Safari, Chrome, and Firefox desktop. Compatibility Risk: Low. This is a new feature, which implemented as an individual internal extension. JSAPI part: Promise <http://dom.spec.whatwg.org/> will be used as per spec indicates. This Promise interface would be the same as other extensions which also has Promise defined in their specs. Java part: Most operations are based on Content Provider<http://developer.android.com/guide/topics/providers/content-providers.html>, which is, using ContentResolver<http://developer.android.com/reference/android/content/ContentResolver.html> to access and modify system's Contact data table <http://developer.android.com/reference/android/provider/ContactsContract.html> as required. There are several major parts described below: 1> For saving or updating a contact, will build an array list of ContentProviderOperation <http://developer.android.com/reference/android/content/ContentProviderOperation.html> and apply to the system's contact table in batch in order to increase performance. 2> For finding a contact, will construct a SQL clause by find option to query contact data table and build results to JSON string to post back to caller. Similarly when removing one or more contacts, will construct a SQL selection clause to delete rows of contact data table. 3> For message handler of Contacts change, will register a Content Observer<http://developer.android.com/reference/android/database/ContentObserver.html> to listen change of contact data table by ContentResolver<http://developer.android.com/reference/android/content/ContentResolver.html>.
