Fragments are not obsolete and are still an important part of the Android development ecosystem. Fragments provide a flexible and reusable way to create UI components that can be used across different activities and layouts.

In fact, fragments are still being actively used and supported by the Android development community, and they are a fundamental part of Android app development. Google has not made any announcements regarding the deprecation of fragments, and they continue to be included in the latest versions of Android.

However, Google has introduced new UI frameworks such as Jetpack Compose that provide an alternative way of building UI components. Jetpack Compose is a modern UI toolkit that allows developers to build declarative, composable UI components in a more efficient and concise way than with traditional Android UI development.

While Jetpack Compose is gaining popularity, it is not meant to replace fragments. Fragments and Jetpack Compose can coexist within an app and can even be used together to create complex UI components.

Therefore, it is safe to say that fragments are not obsolete and will not become obsolete in the near future for Android. They will continue to be a key part of Android app development, alongside new UI frameworks such as Jetpack Compose.
