How to set a name for a specific incoming number on Android?

Question

Java

It is necessary in Android 6+ to display a name for a specific number, as in "anti-spam" programs.

We "add": {title : 'Test title', number : '71234567890'}, now when this number calls the phone it should say 'Test title' somewhere on the screen. In the "Contacts" we do not enter this number.

Prompt, what "technologies to use", where to dig? And is it hard to implement. The final task is to format it as a plugin for Cordova.

I think you need some service that processes incoming calls and checks against your database of numbers, and not against the user's contacts. And then show either a notification or an activity, as you wish. Only with activation there will be problems on sdk> 28
