java - Proguard混淆错误

Question

我正在尝试使用 proguard 来混淆我的 android 项目，我引用了很多来源，但我无法弄清楚，如何正确地做到这一点我的项目包含 Javascript 接口(interface)以及一些动态 javascript 注入(inject)到 webview 中这是我的 Proguard 配置，我尝试排除库、javascript 接口(interface)和注入(inject)器类

-keep class com.codemybrainsout.**
-keep interface ocom.codemybrainsout.**
-keep class com.beardedhen.**
-keep interface ocom.beardedhen.**
-keep class com.flyco.**
-keep interface com.flyco.**
-keep class com.joanzapata.**
-keep interface com.joanzapata.**
-keep class com.pedant.**
-keep interface com.pedant.**
-keep class com.github.**
-keep interface com.github.**
-keep class com.goebl.**
-keep interface com.goebl.**
-keep class com.google.**
-keep interface com.google.**
-keep class com.wdullaer.**
-keep interface com.wdullaer.**
-keep class com.yinglan.**
-keep interface com.yinglan.**
-keep class com.yarolegovich.**
-keep interface com.yarolegovich.**
-keep class me.everything.**
-keep interface me.everything.**
-keep class me.squareup.**
-keep interface me.squareup.**

-keep public class com.apps.appname.Activity.WebActivity
-keep public class com.apps.appname.fillers.*

-keepclassmembers class * {
@android.webkit.JavascriptInterface <methods>;
}

这里的类 com.apps.appname.fillers.* 指的是填充程序包com.apps.appname.Activity.WebActivity 类指的是 Activity

这是我的gradle

构建失败

我想混淆我的代码，这样它就不会轻易地重新编译为新的应用程序，有人早些时候克隆了我的应用程序，我花了很多时间才通知谷歌并将其从商店中删除

Answer 1

我有完全相同的问题，它是在升级到 'com.android.tools.build:gradle:2.3.0' 后开始发生的，因此您可以降级，这个问题就会消失。我知道这并不能解决“在 2.3.0 上使用 proguard 构建失败”的问题，但同时您仍然可以做一些事情。
