Fragments in android


NaN years ago

Fragments in android are part of activities. It might feel confusing to understand the difference but fragments are simply nested activities. It is very used to build advance android applications.

For example, When you swipe left and right on the home screen of Instagram, you can open the camera and chat screen. All these screens are fragments inside one activity, not three activities for each screen.

The biggest drawback of activities in android is that you can perform only one task at a time. Unless you use fragments to perform many tasks at a time on a single activity.
