SyncAdapter(M) Sample Overview

Mobile native

The Sync Adapter sample demonstrates how you can add different sync requests to the sync manager to schedule data synchronization tasks.

The following figure illustrates the main screen of the application.

Figure: Sync Adapter main screen view

Sync Adapter main screen view

The application opens with the main screen, which displays a list of Sync Adapter's features:

  • To create an account, click Create an account.
  • To set the sync in the accountless mode, click Set as accountless.
  • To request all sync jobs with corresponding settings, click Start sync with settings.
  • To get and remove all registered sync jobs, click Manage sync jobs.

The application uses the libaccounts-svc module to work with the accounts database and the elementary module to support the UI requirements.

Prerequisites

  • Sync Adapter's application ID must be org.example.syncadapter.ui, because the Sync Adapter Service uses this ID as a fixed value when it communicates with the Sync Adapter UI application. Otherwise, the application control communication does not operate properly.

    In addition, the Sync Adapter's package name must be org.example.syncadapter (same as the Sync Adapter Service).

  • The Sync Adapter and Sync Adapter Service packages must be coupled during the build process. To couple the packages:
    1. On the Tizen IDE, right-click the Sync Adapter project and select Properties.
    2. Select Project References and find Sync Adapter Service.
    3. Select the Sync Adapter Service check box and click OK.

    In the Project Explorer view, a with SyncAdapter message appears next to the Sync Adapter Service project name showing that you have coupled it successfully.

  • To ensure proper application execution, the following privileges must be set:

    • http://tizen.org/privilege/account.read
    • http://tizen.org/privilege/account.write
    • http://tizen.org/privilege/alarm.set
    • http://tizen.org/privilege/appmanager.launch
    • http://tizen.org/privilege/calendar.read
    • http://tizen.org/privilege/contact.read

Implementation

Application Initialization

To initialize the application:

  1. Launch the Sync Adapter Service, which acts as a sync adapter to this UI application. The service application must be built and included along with the Sync Adapter UI application in the package.

    The SYNC_ADAPTER_SERVICE_APP_ID must be defined as the App ID of the service application which acts as a sync adapter. For more information, see Sync Adapter Service Sample Overview.

    #define SYNC_ADAPTER_SERVICE_APP_ID "org.tizen.syncadapter.service"

/*
 * Draw the Sync Adapter's main menu
 */
static void
create_sync_main_menu(app_data_s *ad)
{
   /*
    * The Sync Adapter should send request to launch the Sync Adapter Service
    * Then, the Sync Adapter Service will set callback functions by using sync-adapter API
    * Without below steps, the Sync Adapter can't receive the result of sync operation
    * through the Sync Adapter Service
    */
   app_control_h app_control;
   int ret = app_control_create(&app_control);
   if (ret != APP_CONTROL_ERROR_NONE) {
      dlog_print(DLOG_INFO, LOG_TAG, "Creating app_control handle is failed [%d : %s]", ret, get_error_message(ret));
      return;
   }
   /* Set the Sync Adapter Service App ID for launching it */
   ret = app_control_set_app_id(app_control, SYNC_ADAPTER_SERVICE_APP_ID);
   if (ret != APP_CONTROL_ERROR_NONE) {

      return;
   }
}
  2. If you click Start Sync on the Start sync with settings screen without selecting an account mode, the Sync Request API cannot deliver the request, and a popup text is shown at the bottom of the screen (on the left in the following figure).

    You must first create an account or set up as accountless on the main screen. Afterwards, you can add sync jobs with the account mode you selected.

    Figure: Select account mode

    Select account Create account Set as accountless

    • Click Create an account to create a dummy account and pass it to the Sync Manager API (the result is shown in the middle in the above figure). Enable sync support on the account.

    • An account handle should be removed when all of the related account sync job is removed.
