All In One Compressor

A simple, sleek Android app for compressing photos, videos, and GIFs with Material You design.

Architecture

• Clean Architecture with 3 layers:

  • Domain Layer: Business logic, models, repository interfaces
  • Data Layer: Repository implementations, local database, compression engines
  • Presentation Layer: UI (Activities, Fragments, ViewModels)

• MVVM Pattern with ViewModels and LiveData/Flow

• Dependency Injection using Hilt

• Material You Design with dynamic colors

Setup Instructions

1. Download FFmpeg Library

Since FFmpeg-kit is not available on Maven Central, you need to download the .aar file manually:

1. Download ffmpeg-kit-min-gpl-5.1.LTS.aar from:

   • https://artifactory.appodeal.com/appodeal-public/com/arthenica/ffmpeg-kit-min-gpl/5.1.LTS/
   • Or use the link from: https://drive.google.com/drive/folders/1o-2jJKMguzQ4-JOOCkginqoE7CAcPy4d

2. Place the downloaded .aar file in: app/libs/

3. The dependency is already configured in app/build.gradle.kts:

   implementation(files("libs/ffmpeg-kit-min-gpl-5.1.LTS.aar"))
   implementation(libs.smart.exception)

2. Add Firebase Configuration

1. Go to Firebase Console
2. Create a new project or use existing one
3. Add Android app with package name: com.matrix.compressor
4. Download google-services.json
5. Place it in app/ directory

3. Build & Run

./gradlew clean build
