With the booming development of social media, mobile applications have become the main way for people to interact socially online. In this blog, we will create a feature-rich Android social media app from scratch. We will cover the following:

1. Project preparation and environment construction

First, make sure you have installed Android Studio and configured your development environment. Create a new Android project, choosing an appropriate app name and target version.

2. Design application interface and layout

Under res/layoutthe directory, create the main interface layout activity_main.xml. We will use RecyclerViewto display the status posted by the user, and also need to add controls such as a bottom navigation bar.
