Can you explain what the term R8 means in the context of development or system?

R8 is a tool for code optimization and minification for Android applications, which has replaced ProGuard in modern projects.

Main features of R8:

• Dead code elimination
• Minification of class, method, and field names to reduce APK size
• Bytecode optimization to improve performance

R8 integrates into the Android build process and helps reduce the final file size and improve application efficiency.

Example of using R8 in Gradle:

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

Here, minifyEnabled true enables R8 for the release build.
