Android Social Media App Development

I need an Android-only social media application built from scratch. The initial release must focus on robust user profiles: secure sign-up/login, editable profile pages with avatar, bio, and basic privacy settings. Code quality and a clean Material-compliant UI are essential because I plan to layer in messaging and photo/video sharing after this first version goes live, so the architecture must be modular and scalable.

Please handle:

• Full Android Studio project with readable, well-commented code
• Compiled APK ready for testing on recent Android versions
• Brief setup guide so I can run and build the project locally

If you can also integrate basic analytics or push notifications, mention it—those could become follow-up tasks.
