NotificationCompat.CallStyle

public class NotificationCompat.CallStyle extends NotificationCompat.Style

java.lang.Object
   ↳ androidx.core.app.NotificationCompat.Style
     ↳ androidx.core.app.NotificationCompat.CallStyle

Helper class for generating large-format notifications that include a caller and required actions, and indicate an incoming call. If the platform does not provide large-format notifications, this method has no effect. The user will always see the normal notification view. This class is a "rebuilder": It attaches to a Builder object and modifies its behavior, like so: 

Notification notification = new NotificationCompat.Builder(mContext)
    .setSmallIcon(R.drawable.new_post)
    .setStyle(
            new Notification.CallStyle.forIncomingCall(caller, declineIntent, answerIntent))
    .build();
Note that for CallStyle Notifications on API versions before 31 to be ranked as they are in API versions 31+, they must be associated with a foreground service. Additionally, CallStyle Notifications on API versions before 31 can achieve the similar ranking by marking the Notification as colorized, using setColorized.
