B4J Question Error occurred For [B4X] Firebase Push Notifications 2023+ B4j Sending tools

Mehrzad238 · Nov 19, 2023

after two years I was back in programming and a lot of things had been changed mostly FCM notification, so tried to work with your example and I was faced with that error and I have no idea how to fix this or what it wants
help me understand how to send notifications in B4J and B4A

Thanks in advance

You haven't downloaded the correct json file. Carefully follow the tutorial instructions.

JSON file has been created by this tutorial

https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/

and of course this one
https://www.b4x.com/android/forum/threads/b4x-firebase-push-notifications-2023.148715/

plus this isn't my first time using Firebase messaging it just Google changed it and the last method was This is not working anymore then I had to create a new JSON following your tutorial, which includes these parts

XML:

{
  "project_info": {
    "project_number": "92*********817",
    "project_id": "myapp1",
    "storage_bucket": "myapp1.appspot.com"
  },
  "client": [
    {
      "client_info": {
        "mobilesdk_app_id": "1:92*********817:android:6c67************c4408",
        "android_client_info": {
          "package_name": "com.myapp1.app"
        }
      },
      "oauth_client": [
        {
          "client_id": "92********817-93t*****************p6jg.apps.googleusercontent.com",
          "client_type": 3
        }
      ],
      "api_key": [
        {
          "current_key": "AIza*********************************zUU"
        }
      ],
      "services": {
        "appinvite_service": {
          "other_platform_oauth_client": [
            {
              "client_id": "92********817-93t*****************p6jg.apps.googleusercontent.com",
              "client_type": 3
            }
          ]
        }
      }
    }
  ],
  "configuration_version": "1"
}

I want to know part of this line code that says file patch and then it's an empty part like

B4X:

" "

what should be in it?

File.OpenInput(FilePath, ""))

and last question is there any JSON other than this google-services.json?
