Android打正式的release包混淆是必备的，避免APP被反编译，使项目中隐秘的技术或信息被别人查看。

Android studio则写在proguard-rules.pro中，当然写在proguard-android.txt中也可以。

 

gradle配置

buildTypes {        release {                   buildConfigField "boolean", "LOG_DEBUG", "false" //不显示log               zipAlignEnabled true     //Zipalign优化              shrinkResources true    // 移除无用的resource文件              minifyEnabled true     //混淆               proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }}

 

 经常用第三方SDK的时候会忘了顺手把混淆加进来，到了打包的时候又去找，很是麻烦，因此在这里总结一下
