Robfuscate

Obfuscate the int index of R.id/R.string/R.layout… in the classes.dex of Android project.

混淆 Android 项目中 R.id/R.string/R.layout… 等在代码中的 int 索引，可以略微提升破解难度。

Before

After

Limitation

It only works for R in the sub modules. For app level module, R.id will be replaced to static int value before Robfuscate so it will not work.

Usage

1. Add the following into your project level build.gradle:

  repositories {
        //...
        maven { url "https://jitpack.io" }
    }
    dependencies {
        //...
        classpath 'com.github.heruoxin:Robfuscate:master'
    }

2. Modify your app level build.gradle:

apply plugin: 'com.android.application'
// NOTICE: Robfuscate must be added AFTER android plugin.
apply plugin: 'com.catchingnow.robfuscate'

Done.
