Creating a Replication-based Push Application

Create a single device application using the Push Synchronization APIs described in this section.

1. Properly configure and deploy the mobile business objects (MBOs).
   1. Create a Cache Group (or use the default) and set the cache policy to Scheduled and set some value for the Cache interval, 30 seconds for example.
   2. Create a Synchronization Group and set some value for the Change detection level, one minute for example.
   3. Place all Mobile Application project MBOs in the same Cache Group and Synchronization Group.
   4. Deploy the Mobile Application Project as Replication-based in the Deployment wizard.
2. Develop the push application.
   1. Generate the Object API code.
   2. Create a new device application in Visual Studio.
   3. Install SybaseServerSync on your Windows Mobile device. The cab file can be found in the <UnwiredPlatform_InstallDir>\ClientAPI\RBS\WM\ServerSync\ folder.
   4. If you have only a single push-enabled application running on the device, write application code that calls the push APIs.
      Note: To run multiple push-enabled applications on a device, see Developer Guide for Windows and Windows Mobile > Reference < Replication-Based Synchronization APIs > Push Configuration APIs > Running Multiple Push-Enabled Applications on a Device.
