Can i change topic from the UI button??

[holymokee]

when i use "android firebase sdk", i can change topic from the UI button..

void buttonLangKor()
{
FirebaseMessaging.getInstance().unsubscribeFromTopic("LangKor");
FirebaseMessaging.getInstance().unsubscribeFromTopic("LangEng");

FirebaseMessaging.getInstance().subscribeToTopic("LangKor");
}

void buttonLangEng()
{
FirebaseMessaging.getInstance().unsubscribeFromTopic("LangKor");
FirebaseMessaging.getInstance().unsubscribeFromTopic("LangEng");

FirebaseMessaging.getInstance().subscribeToTopic("LangEng");
}

But, when i use "unity firebase sdk", i can't change topic from the UI button..
Instead, i can change topic when the app start time..

void Start()
{
....
InitializeFirebase()
...
}

void InitializeFirebase()
{
Firebase.Messaging.FirebaseMessaging.Unsubscribe("LangKor");
Firebase.Messaging.FirebaseMessaging.Unsubscribe("LangEng");

    Firebase.Messaging.FirebaseMessaging.Subscribe("LangKor");
    ....

}

I want to change the topic every time i press the button in the app.

i would appreciate your advice. please help me~~

To clarify, you're saying that topic unsubscription / subscription does not work after the messaging API has been initialized?

If so, which platform have you reproduced the problem on? Is this Android, iOS or both?

This is a bug in the C++ SDK (used by the Unity SDK) on Android.

See https://groups.google.com/d/msg/firebase-talk/Cdvbr_WUNXU/cjRcn42IAgAJ for the details.

Unfortunately, there is no workaround for the moment. I'm putting together a patch now which will be available in our next release.

Thank you for answer.

I'm pleased to announce that we released:

• Firebase C++ SDK 2.1.0 (release notes here, download here)
• Firebase Unity SDK 1.1.0 (release notes here, download here)

I believe this should resolve your issue. If not, please let us know and we'll take a look.

We've updated the Messaging sample with a topic field and subscribe / unsubscribe buttons for you to check out as well.

Cheers,
