    Dear All,

    I had been checking all the previous forum thread on this issue :

    The error code is :
    Running main
    ** Activity (main) Resume **
    *** Service (firebasemessaging) Create ***
    ** Service (firebasemessaging) Start **
    java.lang.NoSuchMethodError: No virtual method subscribeToTopic(Ljava/lang/String;)Lcom/google/android/gms/tasks/Task; in class Lcom/google/firebase/messaging/FirebaseMessaging; or its super classes (declaration of '' appears in /data/app/etp.pushexample-Oh2-nOhEYhTMaMxKZYg2NQ==/base.apk)
    at anywheresoftware.b4a.objects.FirebaseNotificationsService$FirebaseMessageWrapper.SubscribeToTopic(
    at etp.pushexample.firebasemessaging._subscribetotopics(
    at java.lang.reflect.Method.invoke(Native Method)

    The issue about no such method as according to some thread is due to build & run time library(class) is different. But how I update B4 internal library folder, java version whatsoever, it is still the same.

    Kindly help me on the issue above.

    Dear DonManfred,

    First of all, thanks for your reply. I will definitely try it out and let you know.
    By the way do I need to download this jar file and put it to some additional library folder?

    no. it is part of the SDK you downloaded using the B4A SDKManager.

    Hi Erel,

    I am using version 8.3 with no success, than I tried your new version 9.0.
    Both does not work and the more I do update I am facing for library issue like Maven not found error.

    Hi DonManfred,

    I hope you don't mind me ask a simple question. Each time I update B4 it only gave a B4.EXE file. Will do configure and update with the file that you mentioned?
