Getting Detail/Expanded Text from an Android Notification?

Question

I\'ve implemented a notification listener to look out for a Gmail notification.

I want to collect the expanded text (bigtext) from the notification as shown in the n

Answer 1

Finally, I am able to solve this issue by using this code.

ArrayList groupedNotifications = new ArrayList<>();

for(StatusBarNotification statusBarNotification : mNotificationManager.getActiveNotifications()) {
    if(statusBarNotification.getNotification().getGroup().equals(NOTIFICATION_GROUP)) {
          groupedNotifications.add(statusBarNotification);
    }
}

CharSequence stackNotificationMultiLineText[] = groupedNotifications.get(ZEROTH_INDEX).getNotification().extras.getCharSequenceArray(NotificationCompat.EXTRA_TEXT_LINES);

If you try to use getCharSequence("android.textLines"), it returns you null because NotificationCompat.EXTRA_TEXT_LINES returns you the array of CharSequence and not a single CharSequence object.
