Android notifications are messages that inform users about events or updates from an app, even when the app is not in the foreground. They play a vital role in enhancing user engagement and delivering timely information. Notifications appear in the device's **notification drawer** and may also show as **banners, pop-ups**, or on the **lock screen**, depending on the user's settings and Android version. A typical notification can include a title, message text, icon, sound, vibration, and actions (like buttons to reply or dismiss). Developers use the `NotificationManager` and `NotificationCompat.Builder` classes to create and display notifications. Notifications can be simple alerts or more advanced types like progress bars, custom layouts, or grouped notifications. Android also supports **notification channels** (from Android 8.0 onwards), allowing users to control notification behavior per category (e.g., news, messages). Apps must assign notifications to channels to manage importance, sound, and visibility. Additionally, notifications can be used with services like Firebase Cloud Messaging (FCM) to send real-time updates remotely. Overall, notifications are a key part of user experience, helping users stay informed without constantly opening the app. However, developers must use them responsibly to avoid spamming or overwhelming users.
