RemoteInput[] remoteInputs = new RemoteInput[notificationWear.remoteInputs.size()];

Intent localIntent = new Intent();
localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Bundle localBundle = notificationWear.bundle;
int i = 0;
for(RemoteInput remoteIn : notificationWear.remoteInputs){
    getDetailsOfNotification(remoteIn);
    remoteInputs[i] = remoteIn;
    localBundle.putCharSequence(remoteInputs[i].getResultKey(), "Our answer");//This work, apart from Hangouts as probably they need additional parameter (notification_tag?)
    i++;
}
RemoteInput.addResultsToIntent(remoteInputs, localIntent, localBundle);
try {
    notificationWear.pendingIntent.send(MainActivity.this, 0, localIntent);
} catch (PendingIntent.CanceledException e) {
    Log.e(TAG, "replyToLastNotification error: " + e.getLocalizedMessage());
}

its not sending reply as "Our answer". Instead open watsapp window.. please tell me hw to send some fixed reply

also not sending reply as "Our answer". Instead open LINE window.

@technobhardwaj I think you must have been figure out this. here is my work code base on @tajchert.

@RequiresApi(api = Build.VERSION_CODES.KITKAT_WATCH)
   public NotificationWear getNotificationWear(StatusBarNotification statusBarNotification) {
       NotificationWear notificationWear = new NotificationWear();
       Bundle bundle = statusBarNotification.getNotification().extras;
       for (String key : bundle.keySet()) {
           Object value = bundle.get(key);

           if ("android.wearable.EXTENSIONS".equals(key)) {
               Bundle wearBundle = ((Bundle) value);
               for (String keyInner : wearBundle.keySet()) {
                   Object valueInner = wearBundle.get(keyInner);

                   if (keyInner != null && valueInner != null) {
                       if ("actions".equals(keyInner) && valueInner instanceof ArrayList) {
                           ArrayList<Notification.Action> actions = new ArrayList<>();
                           actions.addAll((ArrayList) valueInner);
                           for (Notification.Action act : actions) {
                               if (act.getRemoteInputs() != null) {//API > 20 needed
                                   notificationWear.actionIntent = act.actionIntent;
                                   notificationWear.RemoteInputs = act.getRemoteInputs();
                                   return notificationWear;
                               }
                           }
                       }
                   }
               }
           }
       }

       return null;
   }

   @RequiresApi(api = Build.VERSION_CODES.KITKAT_WATCH)
   public void reply(RemoteInput[] remoteInputs, Bundle bundle, PendingIntent pendingIntent) {

       if (remoteInputs == null || bundle == null || pendingIntent == null)
           return;

       Intent localIntent = new Intent();
       localIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
       Bundle localBundle = bundle;

       for (RemoteInput remoteInput : remoteInputs) {
           localBundle.putCharSequence(remoteInput.getResultKey(), "Our answer");
       }
       RemoteInput.addResultsToIntent(remoteInputs, localIntent, localBundle);
       try {
           pendingIntent.send(this.mContext, 0, localIntent);
       } catch (PendingIntent.CanceledException e) {
           Log.e("", "replyToLastNotification error: " + e.getLocalizedMessage());
       }
   }

public class NotificationWear{
      public android.app.RemoteInput[] RemoteInputs;
      public PendingIntent actionIntent;
   }

where to call reply() function ??
