Add a Beautiful Lock Screen to Any Android App in 5 Minutes (63+ Stars)

Ever wanted to add a lock screen to your Android app but dreaded building one from scratch? I built a library that does it in literally 5 lines of code.

What is AndroidAppLockscreen?

It's a clean, minimal lock screen library for Android. No bloat, no unnecessary permissions — just a beautiful, functional lock screen you can drop into any app.

Why I Built This

I was working on a notes app and needed a PIN lock screen. Every library I found was either:

  • 🚫 Overcomplicated with fingerprint, pattern, AND pin
  • 🚫 Ugly default UI that looked like 2012
  • 🚫 Abandoned with 3-year-old dependencies

So I built one that's simple, beautiful, and actively maintained.

Features

  • 🔒 Clean PIN-based lock screen
  • 🎨 Fully customizable UI (colors, text, buttons)
  • ⚡ Easy integration — 5 lines of code
  • 📦 Lightweight — minimal dependencies
  • 🔧 Works with any Android app

Integration

// That's literally it
new LockScreen(this)
    .setTitle("Enter PIN")
    .setSubtitle("Please enter your 4-digit PIN")
    .start();
Enter fullscreen mode Exit fullscreen mode

The Result

63+ stars and counting. Developers love it because it just works — no configuration hell, no dependency conflicts, no wrestling with lifecycle callbacks.
