IPF - IP Finder

IPF (IP Finder) is a lightweight Android application that displays the IPv4 address of ap0 or wlan0 interfaces without requiring a WiFi connection.

📱 Features

• Shows local IPv4 address of ap0 (Hotspot) and wlan0 (WiFi) interfaces.
• Does not require an active internet or WiFi connection.
• Copy IP address to clipboard with a single tap.
• Built-in refresh button to update IP info.
• Simple, fast, and effective!

🔧 Use Case

This app is especially useful for developers, testers, or tech enthusiasts who:

• Run servers on Android (like HTTP file servers).
• Need local IP for ADB over WiFi or similar.
• Want to debug or view local network interfaces quickly.

⚙️ How It Works

The app queries available NetworkInterfaces, then checks for wlan0 or ap0. If an active IPv4 address is present, it displays it.

if (networkInterface.getName().equalsIgnoreCase("wlan0") ||
    networkInterface.getName().equalsIgnoreCase("ap0")) {
    // Fetch and return the IPv4 address
}

If no IP is available, it shows 127.0.0.1 with a warning.
