Android Studio中的ProGuard提供了非常弱的混淆功能.

在将proguard应用于我的代码后,它仍然非常可读.类和包未重命名.类变量,即所有已重命名的变量.

proguard-rules.pro

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in C:.....proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}
-dontwarn com.github.mikephil.charting.**
-keep class android.support.v7.** { *; }
-keep class android.support.graphics.drawable.** { *; }

查看我的发行版APK

解决方法:

我可以看到您正在使用AppIntro库.该库有一个问题,其中库的保护规则会保留项目中的所有类.库的proguard规则与本地规则合并,因此在最终版本中,所有类都将保留并且不会被混淆.

此问题已在4.2中修复,但尚未在Maven Central上发布此版本.同时,您必须在本地克隆该库,然后在gradle中手动将其导入.

脚步：

>通过Github在本地下载或克隆库(绿色的“克隆”或“下载”按钮)
>在项目的根目录中创建一个新的文件夹库
>在libs文件夹中创建一个新文件夹AppIntro
>将克隆项目的库文件夹的内容放入我们在步骤3中创建的AppIntro文件夹中
>在您的settings.gradle中添加include’：libs：AppIntro’
>用build.gradle中的编译项目(‘：libs：AppIntro’)替换编译’com.github.paolorotolo：appintro：4.1.0′

现在,proguard应该可以正常工作！
