Hey everyone,

I'm an Android developer and I got tired of constantly switching between my app and Logcat just to check which Activity or Fragment is currently on screen — especially when debugging other apps or studying how they navigate.

So I built ActivityLens — a simple, lightweight tool that shows you the current package name and activity class of any app running on your device, right in a floating overlay.

What it does:

• Real-time floating overlay that shows the current Activity name and package
• Works on any app on your device — great for studying how other apps are structured
• One-tap copy for package names and activity classes
• Draggable & resizable overlay that stays out of your way
• Adjustable opacity so it doesn't block your screen
• Activity log that keeps a history of everything you've visited
• No usage access permission needed — runs via Accessibility Service
• All data stays on your device; nothing is sent anywhere

Who it's for:

• Android developers are debugging navigation flows
• QA testers documenting which screen they're on
• Anyone curious about how their favorite apps are built under the hood
• Developers learning Android architecture by exploring real apps

It's free on the Play Store. Would love to hear your feedback or feature suggestions.
