9 ## ProGuard vs R8
11 ProGuard is the original open-source tool used by many Android applications to
12 perform whole-program bytecode optimization. [R8](https://r8.googlesource.com/r8),
13 is a re-implementation that is used by Chrome (and the default for Android Studio).
14 The terms "ProGuard" and "R8" are used interchangeably within Chromium but
17 ## What does ProGuard do?
19 1. Shrinking: ProGuard will remove unused code. This is especially useful
22 2. Obfuscation: ProGuard will rename classes/fields/methods to use shorter
25 3. Optimization: ProGuard performs a series of optimizations to shrink code
31 ProGuard is enabled only for release builds of Chrome because it is a slow build
35 ### ProGuard configuration files
37 Most GN Java targets can specify ProGuard configuration files by setting the
38 `proguard_configs` variable. [//base/android/proguard](/base/android/proguard)
43 When `is_java_debug = false` and a target has enabled ProGuard, the `proguard`
44 step generates the `.dex` files for the application. The `proguard` step takes
45 as input a list of `.jar` files, runs R8/ProGuard on those `.jar` files, and
50 Obfuscation can be turned off for local builds while leaving ProGuard enabled
