混淆后无法运行

[eaglelzy]

我导入demo可以正常运行，但是在宿主工程打开混淆开关后，就无法运行了，请问混淆要注意什么吗？

buildTypes {
        debug {
            minifyEnabled true
            signingConfig signingConfigs.debug
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        release {
            minifyEnabled true
            signingConfig signingConfigs.release
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

运行后的异常日志：

确认问题，安排在近期解决。

已支持宿主代码混淆，请更新最新代码，配置混淆如Sample/app/proguard-rules.pro：

# Support Libraries
-dontwarn android.support.**
-keep class android.support.** { *; }
-keep interface android.support.** { *; }

# Small
-keep class net.wequick.small.Small { public *; }
-keep interface net.wequick.small.** { *; }

为了解构我们一般都很少将代码放到宿主中,所以支持宿主混淆作用不大.插件混淆基本没法使用,lib使用混淆直接报错,而app会将一些公共库重新打包到自己.混淆是减少体积和提高安全性,能不能实现呢？

[galenlin]

因为我们要从插件中分离出公共代码，如果要支持混淆，会很麻烦：

1. 混淆时需要所有的类参与，意味着不能前期分离
2. 混淆后包名、类(文件)名面目全非，甚至会额外抽取出一些额外的类(文件)，意味着后期也很难分离

所以这个活很细呀，思路虽然有，但是具体操作起来恐怕没有那么顺利，需要时间。

gradle-small:0.9.0 已支持混淆，关闭本问题
