Programmatically accept call in Nougat

Question

From one year, I have been working over IOT product and the application attached was working fine. Now I am not able to accept call programmatically in higher versions of an

Answer 1

For answering a call using a button, set a flag whenever an incoming call is detected:

 if(state==TelephonyManager.CALL_STATE_RINGING){
           shouldAnswerCallViaNotification = true;
        } else {
            shouldAnswerCallViaNotification = false;
        }

Now, create a list in your NSLogService class,

static ArrayList statusBarNotifications;

and in your onNotificationPosted() add StatusBarNotification to a list,

   @Override
public void onNotificationPosted(StatusBarNotification sbn) {

    if (HomeScreen.shouldAnswerCallViaNotification) {
        if (statusBarNotifications == null) {
            updateNotificationList();
        }
       statusBarNotifications.add(sbn);

    } else {
        updateNotificationList();
    }

}
 public static ArrayList getAllNotifications() {
    return statusBarNotifications;
}

public static void updateNotificationList() {

    if (statusBarNotifications != null)
        statusBarNotifications = null;
    statusBarNotifications = new ArrayList();
}

In your HomeScreen, on Button click, call performNotificationOperation(NLService.getAllNotifications());

here is a definition for this method:

 private void performNotificationOperation(ArrayList activeNotifications) {

    if (activeNotifications.size()> 0) {
        main_Loop:
        for (StatusBarNotification notification : activeNotifications) {
            try {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
                    if (notification.getNotification().actions != null) {
                        for (Notification.Action action : notification.getNotification().actions) {
                            //            Log.e(TAG, "" + action);

                            Log.e(TAG, "" + action.title);
                            if (action.title.toString().equalsIgnoreCase("Answer")) {
                                Log.e(TAG, "" + true);
                                PendingIntent intent = action.actionIntent;

                                try {
                                    intent.send();
                                } catch (PendingIntent.CanceledException e) {
                                    e.printStackTrace();
                                }
                                break main_Loop;
                            }


                        }
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }

        }
    }
    try {
        NLService.updateNotificationList();
    } catch (Exception e) {
        e.printStackTrace();
    }

}
