CommunicationBlockAndFilter

Communication blocking and filtering sample

This sample shows how to make a block and filter application for call and text message. It uses the CommunicationBlockingAppManager class to set itself as the active communication blocking app and uses the PhoneCallBlocking class to set the phone numbers which are blocked.

This sample demonstrates how to

• Register background tasks for blocking and filtering calls and text messages.
  • A task which runs when the session starts. The task sets the blocked number list.
  • A task which runs when the app becomes the active communication blocking app. The task sets the blocked number list.
  • A task which runs when a call is blocked.
  • A task which runs when a text message is blocked.
  • A task which runs when a text message is received. The task evaluates the text message and decide whether to block it.
• Determine whether the app is the the active communication blocking app.
• Display the system UI to let the user choose a communication blocking app.
• Set the phone numbers which are blocked.

See the Package.appxmanifest file for the extensions and capabilities a communication blocking and filtering app must declare.
