WebView Instagram App

A minimal Kotlin based Android app that loads Instagram in a WebView, keeps the user logged in, and automatically force-closes after 15 minutes of use. It then requres a 2-minute cooldown period before allowing the app to re-launch, with ProGuard/R8 minification for a smaller APK.

High-Level Overview

This project exemplifies end-to-end Android proficiency by combining:

• A single-activity architecture in Kotlin.
• Seamless WebView integration with persistent Instagram sessions.
• Lifecycle management: forced close after 15 minutes, with a 2-minute cooldown enforced on relaunch.
• Performance optimization through ProGuard/R8 code and resource shrinking, yielding a minimalist APK size.

Project Structure

• MainActivity.kt:
  Implements the WebView, time-limited session logic, and preference checks.
• activity_main.xml:
  Hosts a single <WebView> component.
• AndroidManifest.xml:
  Declares needed permissions (Internet) and sets the Activity.

Setup & Build

1. Clone or Download this repository.
2. Open in Android Studio:
3. Ensure Kotlin support and API 28 SDK are installed.
4. Build & Run

Usage Flow

1. Launch the App

   • Loads instagram.com in a WebView.
   • Log in once; session cookies persist for future launches.

2. Active Usage

   • A 15-minute timer commences on launch.
   • The app auto-closes upon timer expiration, storing a closure timestamp.

3. Cooldown

   • Attempting to reopen within 2 minutes results in immediate closure.
   • After 2 minutes, usage is restored.

Customization

• Time Constraints: Modify USE_TIME_MINUTES and COOL_DOWN_MINUTES in MainActivity.kt.
• Target URL: Change the loaded URL in webView.loadUrl(...).

Security & Privacy

• Session Security: Cookies reside on the device; unauthorized access to the device can compromise the session.
• Forced Closure: Non-standard in typical Android apps—validate policy and user acceptance if distributing publicly.
