Thank you and congratulations for sending the first "intent to implement" mail in the history of Crosswalk!
From: Crosswalk-dev [mailto:crosswalk-dev-boun...@lists.crosswalk-project.org] On Behalf Of Huang, Deqing Sent: Friday, November 08, 2013 9:19 AM To: crosswalk-dev@lists.crosswalk-project.org Subject: [Crosswalk-dev] Intent to Implement: [Android] W3C SysApps Contacts API Description: This implemented W3C Contacts Manager API on Android Affected component: N/A Related feature: XWALK-49<https://crosswalk-project.org/jira/browse/XWALK-49> Target Release: Crosswalk M4 Implementation details: Spec: http://www.w3.org/2012/sysapps/contacts-manager-api/ Summary: This API is designed as an internal extension based the XWalkExtensionBridge<https://github.com/crosswalk-project/crosswalk/pull/513>. 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>.
