Frequently Asked Questions

Everything you need to know

What is ProGuard?

ProGuard is a tool that helps optimize, obfuscate, and shrink your Android app code, making it harder to reverse engineer.

How does R8 differ from ProGuard?

R8 is a more recent tool that combines the features of ProGuard with additional optimizations and is integrated into the Android build process.

Why should I use an obfuscation tool for my Android app?

Using an obfuscation tool like ProGuard or R8 helps protect your app's code from reverse engineering, improves performance, and reduces the app size.

Can I use these generated rules in production?

Yes! The generated rules follow Android best practices and are production-ready. However, always test your app thoroughly after enabling ProGuard to ensure nothing breaks.

How do I add ProGuard rules to my Android project?

Copy the generated rules to your app's proguard-rules.pro file in the app module, then ensure minifyEnabled is set to true in your build.gradle file.

What happens if I don't include the right ProGuard rules?

Missing ProGuard rules can cause runtime crashes, especially with libraries that use reflection. Generated rules help prevent these issues by keeping necessary classes.
