This article unfolds the Firebase journey in a friendly, step‑by‑step narrative. First, we clarify what Web Messaging means in the context of Android, then we explore the project prerequisites, from signing in to the console to installing SDKs. Next, we detail the configuration files and permissions, ensuring you can build a seamless notification pipeline. Finally, we cover how to test and troubleshoot messages locally and in production.
After setting up, you’ll be able to send test notifications to your Android app and a web browser, and see them appear instantly.
