Battery Charging Animation

Overview

Battery Charging Animation shows a full-screen animated display whenever the phone is plugged in, along with the battery's live stats.

What It Does

• 5 animation styles: Electric Lightning, Fire Flames, Neon Glow, Water Fill and Space Stars
• Live battery details: charge percentage, charging status, temperature and voltage
• Turns on automatically when a charger is connected (this can be switched off)
• Preview any style before using it
• Tap Close to dismiss the screen

How It's Built

• Custom animation view draws every effect on a Canvas.
• Detects charging with a foreground service and a power-connected receiver.
• Keeps working after a restart: a boot receiver restarts monitoring when the phone reboots.
• Reads battery data from the system's battery broadcast.
