字符串混淆插件 2 | 3 | 1. 插件只能混淆java层代码 4 | 2. 插件只能在application类型的module中使用，插件会混淆application module所依赖的module和jar。所以请添加你要混淆的包名，否则所有第三方SDK都会被混淆 5 | 6 | ### 使用 7 | 8 | #### 方式一 9 | 10 | 在项目跟目录下的`build.gradle`文件中添加以下代码 11 | 12 | ```groovy 13 | buildscript { 14 | repositories { 15 | ... 16 | maven { url 'https://jitpack.io' } 17 | } 18 | dependencies { 19 | ... 20 | classpath 'com.github.wuzuchang:StringObfuscatedPlugin:2.1.0' 21 | } 22 | } 23 | 24 | allprojects { 25 | repositories { 26 | ... 27 | maven { url 'https://jitpack.io' } 28 | } 29 | } 30 | ``` 31 | 32 | 在app module下的`build.gradle`中添加以下代码 33 | 34 | ```groovy 35 | plugins { 36 | id 'com.android.application' 37 | // 字符串混淆插件 38 | id 'com.wzc.string.obfuscate' 39 | } 40 | stringObfuscate{ 41 | openLog = true 42 | // 添加需要混淆的包名 43 | packageName = ["com.wzc.gradle.plugin","com.wzc.test"] 44 | } 45 | ``` 46 | 47 | #### 方式二 48 | 49 | 下载[插件jar](https://github.com/wuzuchang/StringObfuscatedPlugin/raw/master/plugin_libs/StringObfuscatePlugin-1.0.0.jar)文件，复制到项目中的plugin_libs目录下(没有就新增目录) 50 | 51 | ```java 52 | ├── plugin_libs 53 | │ └──
