FBD – Freehand Boomer Downloader

FBD is an Android WebView application designed to automate a very specific workflow:
load a target webpage, trigger a download action automatically, notify the user, and exit cleanly.

This app is built for speed, automation, and minimal user interaction, not for casual browsing.

---

🎯 Purpose

Most WebView apps are bloated wrappers.
FBD is different: it exists to do one job efficiently.

Workflow:

1. Open a predefined webpage
2. Detect a specific page (download.php)
3. Automatically click the download trigger (id="hdlink")
4. Wait for the system download to start
5. Show a confirmation toast
6. Close the app immediately

No extra taps. No confusion.

🔐 Permissions

The application asks for only one permission:

<uses-permission android:name="android.permission.INTERNET" />

🧠 Core Logic

Page Detection

The app checks the loaded URL and triggers logic only when the target page is reached.

JavaScript Injection

Used to automatically click the download button:

document.getElementById("hdlink")?.click();

Download Handling

Once the system confirms the download has started:

• A toast is shown: “Download started”

• The application exits immediately

⚙️ Configuration

You can easily modify:

• Target URL

• Page match condition

• Button ID to trigger

• Auto-exit behavior

• Header UI elements

⚠️ Limitations

• DOM-dependent (site structure changes can break automation)

• Not intended for dynamic JS-heavy sites

• Requires the target site to allow WebView interaction

• This is a precision tool, not a universal downloader.

📦 Use Cases

• Automated file triggering

• Controlled download flows

• Single-purpose web automation

• Lightweight wrapper for repetitive tasks

• Can be used as a template for other such websites
