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