The Linkrunner Android SDK provides native integration for Linkrunner functionality in Android applications.

Features

• Easy initialization and setup

• User management and tracking

• Payment tracking and management

• Event tracking

• Deeplink handling

Installation

dependencies {
    implementation 'io.linkrunner:android-sdk:1.0.0'
}

Measuring LinkRunner SDK Size Impact

Quick Size Overview

• Download Size: 123KB (AAR file)

• Estimated APK Impact: 30-80KB (varies by app configuration)

• Method Count: ~300 methods

How to Measure SDK Size Impact in Your App

Method 1: Before/After APK Comparison (Simplest)

1. Measure Base APK Size:

   # Build your app WITHOUT LinkRunner SDK
   ./gradlew assembleRelease
   # Note the size
   ls -lh app/build/outputs/apk/release/app-release.apk

2. Add LinkRunner SDK:

   // In app/build.gradle
   dependencies {
       implementation 'io.linkrunner:android-sdk:2.1.5'
   }

3. Measure New APK Size:

   ./gradlew clean assembleRelease
   ls -lh app/build/outputs/apk/release/app-release.apk

4. Calculate Impact:

• SDK Impact = New APK Size - Original APK Size

Method 2: Using Android Studio APK Analyzer

1. Open Android Studio

2. Analyze Base APK:

• Build your app without SDK

• Go to Build > Analyze APK

• Select your APK

• Note total size and DEX size

3. Analyze With SDK:

• Add LinkRunner SDK

• Build again

• Analyze new APK

• Compare sizes

• Look for io.linkrunner in DEX files

4. Key Metrics to Check:

• Total APK size difference

• DEX file size increase

• Number of methods added

• New dependencies introduced

Method 3: Using Gradle Build Analysis

Add this to your app's build.gradle:

android {
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

// Add at the end of the file
tasks.register("apkSizeReport") {
    doLast {
        def apkDir = new File("${project.buildDir}/outputs/apk/release")
        apkDir.listFiles().each { file ->
            if (file.name.endsWith('.apk')) {
                println "APK: ${file.name}"
                println "Size: ${file.length() / 1024 / 1024} MB"
            }
        }
    }
}

Then run:

./gradlew clean assembleRelease apkSizeReport

Size Optimization Tips

1. Enable R8/ProGuard:

   android {
       buildTypes {
           release {
               minifyEnabled true
               shrinkResources true
           }
       }
   }

2. Add ProGuard Rules:

   # Add to proguard-rules.pro
   -keep class io.linkrunner.sdk.** { *; }

3. Enable ABI Filters if you don't need all architectures:

   android {
       defaultConfig {
           ndk {
               abiFilters 'armeabi-v7a', 'arm64-v8a'
           }
       }
   }

Expected Size Impact

Dependency Size Breakdown

Our SDK uses these major dependencies:

• Retrofit + OkHttp: ~150-200KB

• Coroutines: ~100-150KB

• Koin: ~50KB

• Play Services: ~100KB

Note: If your app already uses these dependencies, they won't add to the final APK size.

Troubleshooting Size Issues

If you see unexpectedly large size increases:

1. Check Dependency Conflicts:

   ./gradlew app:dependencies

2. Analyze DEX Content:

• Use Android Studio's APK Analyzer

• Look for duplicate classes

• Check if R8/ProGuard is working correctly

3. Enable Detailed Build Reports:

   android {
       buildTypes {
           release {
               minifyEnabled true
               shrinkResources true
               proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
           }
       }
   }
