Galaxy S3 Build Configuration	Java 21 toolchain configuration for Android API 18-21 with desugaring	reference

Working Configuration for Samsung Galaxy S3

Why: Galaxy S3 has Android 4.3 (API 18) with 1GB RAM. Java 21 features need desugaring.

How to apply:

build.gradle (app level)

android {
    namespace 'com.helldivers.app'
    compileSdk 28

    defaultConfig {
        minSdk 18
        targetSdk 21
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_21
        targetCompatibility JavaVersion.VERSION_21
        coreLibraryDesugaringEnabled true
    }

    java {
        toolchain {
            languageVersion = JavaLanguageVersion.of(21)
        }
    }
}

dependencies {
    coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:2.0.4'
}

AndroidManifest.xml

<uses-sdk android:minSdkVersion="18" android:targetSdkVersion="21" />
<application android:hardwareAccelerated="false">

Key optimizations for 1GB RAM:

• Use Theme.Holo instead of AppCompat
• LinearLayout preferred over ConstraintLayout
• RGB_565 for bitmaps
• Disable hardware acceleration on problematic API 18
• Minimize overdraw
