Question

I have developed a windows phone app that sends notification to users. There is a cloud service that send notification via mspn and an app running on windows phone. My cloud service will send notification based on current location of the phone . The app running in windows phone needs to register the current location of the device on cloud service every 12 hours. My app wont be running 24hour. So how can i update the device’s position after every 12 hours? Can i run my app in background? Has anyone faced a similar situation?

Answer 1

You can run Periodic Agent in the background. More info can be fount on MSDN:

• Background Agents Overview for Windows Phone
• How to: Implement Background Agents for Windows Phone

When you want use GeoCoordinateWatcher inside your background agent you have to know about some limits:

This API, used for obtaining the geographic coordinates of the device,
is supported for use in background agents, but it uses a cached
location value instead of real-time data. The cached location value is
updated by the device every 15 minutes.
