Hot answers tagged dexguard day week month year all. How does DexGuard encrypt classes? ProGuard provides name obfuscation: it can replace the original names of classes, methods, and fields by short, meaningless names.

DexGuard additionally provides string encryption and class encryption. The term encryption may be confusing in this context, since these are basically more aggressive types of obfuscation. Designated strings and classes are Eric Lafortune Setting up dexguard license file in android studio.

R8 is an APK minification tool, and it is not a goal to try to make the code difficult to reverse engineer.

The term "obfuscation" is inherited from ProGuard, but internally in the code base the term "minification" is used. For completeness' sake: we've worked out by e-mail that the problem was caused by the option "minifyEnabled true" in build.

DexGuard of course already provides shrinking, optimization, and obfuscation.

Related Hot Network Questions. Question feed. Stack Overflow works best with JavaScript enabled.R8: October edition ]. The new Android D8 compiler is the default compiler for Dalvik bytecode now. The optimizing compiler R8 is growing on the horizon, so we get a lot of questions how it relates to ProGuard.

In this blog, we'll have a closer look. Dalvik bytecode is a fundamental part of most apps, so it rightly receives a lot of attention in the build process. Developers write their code in Java or Kotlin, but Android devices expect Dalvik bytecode. The compilation process for optimized releases has long looked as follows:. The traditional Java compiler compiles source code to Java bytecode. ProGuard can optionally optimize this code, producing Java bytecode that is smaller and faster.

The dx compiler can finally convert this Java bytecode to Dalvik bytecode. The Dalvik bytecode is packaged in the apk file and eventually installed on the device.

There's a wide range of Android devices with many constraints in processing power, memory, and bandwidth, so even in this day and age, the size and efficiency of the bytecode remains important. For developers, the performance of the build process is at least as important, so aroundthe Android team introduced the compilers Jack and Jill. They integrated the functionality of the Java compiler, ProGuard, and the Dalvik compiler in a single step:.

It greatly streamlined the build process, but didn't play very nice with the ecosystem of languages and tools that work with Java bytecode. The Android team abandoned it in With the new D8 compiler, they take a step back, simply replacing the dx compiler with a fresh implementation:. This setup provides a more gentle evolution, accommodating external tools.

If anything, it still allows the Kotlin language to grow successfully. Moreover, D8 already produces better quality bytecode than dx, with fewer instructions and better register allocation.DexGuard is based on ProGuard.

That is the reason why it is so easy to upgrade to DexGuard. But both products offer widely different functionality. ProGuard is a generic optimizer for Java bytecode while DexGuard provides advanced protection for Android applications. In this blog, you will find an overview of the differences between ProGuard and DexGuard.

ProGuard is a versatile optimizer for Java bytecode. It enables you to shrink, optimize and obfuscate desktop applications, embedded applications and mobile applications Android. DexGuard, on the other hand, is specifically designed to protect and optimize Android applications.

The multilayered protection DexGuard provides is adapted to the distributed and quickly evolving environment in which mobile applications are used.

In addition, DexGuard offers functionality that helps you to make optimal use of the Android platform. ProGuard offers basic protection against static analysis only, while DexGuard shields applications from both static and dynamic analysis. DexGuard does not only harden the source code of the application using a multitude of obfuscation and encryption techniques but also integrates a series of runtime security mechanisms runtime application self-protection into it.

These mechanisms check the integrity of the application and of the environment in which it is running and enables the application to react whenever suspicious activity is detected. Both ProGuard and DexGuard harden the code of applications to shield them from reverse engineering, but the extent to which they do is different.

ProGuard offers basic protection in the form of name obfuscation.

r8 vs dexguard

DexGuard does not only obfuscate names of classes, fields and methods, but also arithmetic and logical expressions in the code and the control flow of the code inside methods. The result is a much better protected application.

Besides the Dalvik bytecode, it optimizes, obfuscates and encrypts manifest files, native libraries, resources, resource files and asset files. ProGuard can be downloaded and used free of charge to process your commercial and non-commercial applications.

All the information you need to set up ProGuard is detailed in the online manual. DexGuard is a commercial product. A license allows you to use DexGuard and gives you access to a team of experienced engineers that can help you set up and configure the software.

If anything, it still allows the Kotlin language to grow successfully. Moreover, D8 already produces better quality bytecode than dx, with fewer instructions and better register allocation. That still leaves room for optimizing the build process: R8 is a spin-off of D8 that aims to integrate the functionality of ProGuard and D Shrinking and name obfuscation are fairly standard techniques.

Partners Learn about our global network of distributors, integrations, and technology partners. The global reference in mobile application protection Discover our products.To make your app as small as possible, you should enable shrinking in your release build to remove unused code and resources.

This page describes how R8 performs these compile-time tasks for your project and how you can customize them. When you build you project using Android Gradle plugin 3. Instead, the plugin works with the R8 compiler to handle the following compile-time tasks:. When building the release version of your app, by default, R8 automatically performs the compile-time tasks described above for you. In fact, R8 works with all of your existing ProGuard rules filesso updating the Android Gradle plugin to use R8 should not require you to change your existing rules.

When you use Android Studio 3. However, when you create a new project using Android Studio, shrinking, obfuscation, and code optimization is not enabled by default. To enable shrinking, obfuscation, and optimization, include the following in your project-level build. The table below describes the sources of ProGuard rules files that R8 uses. By default, this file does not apply any rules. So, include your own ProGuard rules here, such as your custom keep rules. Android Gradle plugin Generated by the Android Gradle plugin at compile time.

The Android Gradle plugin generates proguard-android-optimize. By default, when creating a new module using Android Studio, the module-level build.

Note: The Android Gradle plugin includes additional predefined ProGuard rules files, but it is recommended that you use proguard-android-optimize. Using rules files that are packaged with AAR libraries is useful if certain keep rules are required for the library to function properly—that is, the library developer has performed the troubleshooting steps for you. However, you should be aware that, because ProGuard rules are additivecertain rules that an AAR library dependency includes cannot be removed and might impact the compilation of other parts of your app.

For example, if a library includes a rule to disable code optimizations, that rule disables optimizations for your entire project. You can include additional configurationsand R8 applies them at compile-time. When you set the minifyEnabled property to trueR8 combines rules from all the available sources listed above. This is important to remember when you troubleshoot with R8because other compile-time dependencies, such as library dependencies, may introduce changes to the R8 behavior that you do not know about.

For example, you can add rules that are specific to each build variant by adding another proguardFiles property in the corresponding productFlavor block. The following Gradle file adds flavor2-rules. Now, flavor2 uses all three ProGuard rules because those from the release block are also applied. Code shrinking with R8 is enabled by default when you set the minifyEnabled property to true.
