🔧 Build Configuration

1. Update Version Information

Edit app/build.gradle:

android {
    defaultConfig {
        applicationId 'com.dxbmark.nfcmanager'
        minSdkVersion 30
        targetSdkVersion 34
        versionCode 1          // Increment for each release
        versionName "1.0.0"    // Update version string
    }
}

2. Configure Signing

Create keystore.properties in project root:

storePassword=YOUR_STORE_PASSWORD
keyPassword=YOUR_KEY_PASSWORD
keyAlias=YOUR_KEY_ALIAS
storeFile=path/to/your/keystore.jks

Update app/build.gradle:

android {
    signingConfigs {
        release {
            if (project.hasProperty('MYAPP_UPLOAD_STORE_FILE')) {
                storeFile file(MYAPP_UPLOAD_STORE_FILE)
                storePassword MYAPP_UPLOAD_STORE_PASSWORD
                keyAlias MYAPP_UPLOAD_KEY_ALIAS
                keyPassword MYAPP_UPLOAD_KEY_PASSWORD
            }
        }
    }
    
    buildTypes {
        release {
            signingConfig signingConfigs.release
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro"
            debuggable false
            zipAlignEnabled true
        }
    }
}

3. Generate Keystore (First Time Only)

# Generate new keystore
keytool -genkey -v -keystore nfc-manager-release.jks \
        -keyalg RSA -keysize 2048 -validity 10000 \
        -alias nfc-manager-key

# Verify keystore
keytool -list -v -keystore nfc-manager-release.jks

🏗️ Building Release APK/AAB

1. Clean Build

cd android
./gradlew clean

2. Build Release AAB (Recommended)

# Build Android App Bundle (AAB)
./gradlew bundleRelease

# Output location:
# app/build/outputs/bundle/release/app-release.aab

3. Build Release APK (Alternative)

# Build APK
./gradlew assembleRelease

# Output location:
# app/build/outputs/apk/release/app-release.apk

4. Verify Build

# Check APK/AAB details
aapt dump badging app/build/outputs/apk/release/app-release.apk

# Verify ProGuard mapping
ls -la app/build/outputs/mapping/release/

🔍 Testing Release Build

1. Install and Test

# Install release APK
adb install app/build/outputs/apk/release/app-release.apk

# Test on multiple devices
adb devices

# Check logs (should be minimal)
adb logcat | grep "NFCManager"

2. Verify Security Features

  • ✅ No debug logs appear in logcat
  • ✅ Code is obfuscated (check mapping.txt)
  • ✅ APK size is optimized (~8MB)
  • ✅ All features work correctly
  • ✅ Permissions are minimal (8 only)

3. Performance Testing

# Monitor memory usage
adb shell dumpsys meminfo com.dxbmark.nfcmanager

# Monitor battery usage
adb shell dumpsys batterystats --charged com.dxbmark.nfcmanager

# Monitor CPU usage
adb shell top | grep nfcmanager
