Demo — Why Anti Spam uses FOREGROUND_SERVICE_DATA_SYNC

Описание: This short video demonstrates how Anti Spam uses a foreground service to continuously monitor and handle incoming calls in real time, even when the app is in the background. The foreground service is required so the app can immediately apply user-configured blocking rules (allow only contacts, block unknown numbers, prefix filters, silent mode) at the moment a call arrives. All processing is performed locally on the device; no call data is uploaded or shared. The persistent notification shown in the video indicates the foreground service is active.

How to reproduce (paste this):

Turn on Call Blocking and grant the required permissions.

Call from a number that is saved in Contacts — call is allowed.

Delete that number from Contacts.

Call again from the same number — the app blocks/diverts the call (appears as missed call).
This sequence demonstrates that the app is monitoring incoming calls continuously and applying rules without user interaction.
