Gradle Konfigürasyonu

android/app/build.gradle (Hibrit Yaklaşım)

android {
    ...
    defaultConfig { ... }

    // Signing configs (Env Vars > gradle.properties)
    signingConfigs {
        debug {
            storeFile file('debug.keystore')
            storePassword 'android'
            keyAlias 'androiddebugkey'
            keyPassword 'android'
        }
        release {

            def keystoreFile = System.getenv("MYAPP_UPLOAD_STORE_FILE") ?: project.findProperty("MYAPP_UPLOAD_STORE_FILE")
            def keystorePassword = System.getenv("MYAPP_UPLOAD_STORE_PASSWORD") ?: project.findProperty("MYAPP_UPLOAD_STORE_PASSWORD")

            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'

[!TIP] Hibrit Yaklaşım Avantajları:

• Local development: gradle.properties kullanır
• CI/CD: Environment variables kullanır (daha güvenli)
• gradle.properties dosyası oluşturmaya gerek kalmaz
