AS 混淆

混淆apk是在build Generate Signed APK時產生的

1.build.gradle

AS默認的混淆是關閉的需要打開
model的build.gradle的buildTypes下修改
  buildTypes {
        release {
            minifyEnabled true //modify true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

2.混淆規則把規則添加到proguard-rules.pro
