Hi Sir,

Where can I find the Source for FCM Server

I get MISSING_INSTANCEID_SERVICE in titlebar and toast.

How can I debug?

I use microG. FCM-toolbox did not registered, but some other apps can receive message.

Versions

• FCM toolbox : 1.8.4
• microG Services Core : 0.2.22.212658
• microG Services Framework Proxy : 0.1.0

I just started using Firebase recently, the default configuration of Firebase is Firebase Cloud Messaging API, and it took me a while to find the API key for Cloud Messaging API.
Planning to migrate from Cloud Messaging API to Firebase Cloud Messaging API?

Hi, can you assist me in sending notification via topic in the web app

How can one achieve it?

Hi!

Thanks for this great tool 👍 ! I wanted to ask whether topic conditions (search for condition) are supported or there is plan to support them in the future.

I could also offer to do a pull request to enable this.

Best,
Peter

Hi Simon,
great tool! However, I have a suggestion: is it hard for you to add a feature to receive notification when app is background?

Currently, even when app is running (is on task list) after sometime app disconnect from FCM service (app icon not green).

It would be very helpful is app could be running in the background (as a service) and receive notification even when the phone is locked- just like Signal or Whatsapp do.

Regards
Chris

I cloned the project the system works amazing! Thank you!
If I understood correctly I should see on the messaging page, all the devices connected to the app, can you understand why I do not see the connected devices?

I want to point out that once I connect to the app on the phone, the connection appears in the Realtime Database, but is not updated in my web app.

Thank you very much 👍

Hi! I want to rebuild your app with my FCM credentials but i have an error "No matching client found for package name 'fr.smarquis.fcm'"
What i do wrong? i build it throught Android Studio using Build tab. Thanks!

What I have done

1. Git clone the project, download google-services.json, replace the original one in app folder, compile using Android studio 2022.2.1
2. Launch FCM-toolbox app, get token
3. Configurate the FCM-toolbox webpage with my Cloud Messaging API (Legacy) and Realtime Database url and the device token

What happened

1. The indicator of FCM-toolbox is green
2. While I click the "Sent" botton on the webpage, it shows

{
"to": "token",
"time_to_live": 60,
"priority": "high",
"data": {
"ping": {}
}
}
{
"multicast_id": xxxxxxx,
"success": 1,
"failure": 0,
"canonical_ids": 0,
"results": [
{
"message_id": "0:xxxxxxx"
}
]
}

3. The APP on my phone crash, possibly related logcat

Enviroment:

• Sender:

  • FCM-toolbox webpage

• Receiver:

  • Android 12, with self configurated and compiled FCM-toolbox

• FCM config:

  • Messaging:
    • Add package fr.smarquis.fcm
    • Enable Cloud Messaging API (Legacy)
  • Realtime Database:
    • Create new database
    • Set rules for read and write to be "true"

I tried the official FCM-toolbox, everything works well.

Sorry but I'm new to FCM and android, is there anything wrong with my config?

Hi Simon
Great project as always..
Thanks for sharing the source code!
I encountered an error while building in the build.gradle file sync phase
This version of the Android Support plugin for IntelliJ IDEA (or Android Studio) cannot open this project, please retry with version 2021.1.1 or newer.
I tried to find solutions to this error in Google, but they created other errors in the project.
Is there a way to build properly?

(I'm using the latest Android Studio version)

Thank you!

the mobile app is awesome,can u pls open source ur webapp too
