本文介绍Android应用发布前的签名流程及代码混淆方法。包括使用Gradle进行配置、混淆规则自定义、以及如何验证混淆效果等内容。

签名

路径/文件名+.jks 签名文件通过

build generate signed apk

记住签名库的密码

和key 的密码

代码混淆

混淆代码可以减小APK体积，将类名简单化，在反编译时打乱代码的阅读理解。

所以release 版本的apk 通常进行代码混淆

通过Gradle 进行配置

buildTypes 声明构建类型

1.release

2.debug

3.可以自定义类型

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

将minifyEnabled 更改为Ture

更改proguard-rules.pro混淆文件自己配置：
