代码不会被 Proguard 混淆？

Question

我在我的 android studio 中使用 proguard。我在我的 proguard-rules.pro 文件中实现了 Proguard。但是在发布 apk 之后，代码并没有被混淆。

这是 proguard-rules.pro 文件

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /home/chitra/Android/Sdk/tools/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 *;
#}

这可能是什么问题？请告诉我。

Answer 1

原因很可能是您在规则中排除了自己的代码。

所以你的代码没有运行混淆。

从您的问题来看，我不知道您的命名空间，但以下几行会影响一开始的 com. 的任何内容。

因此，如果您的命名空间是 com.my.namespace，它将被排除在混淆之外。

您应该考虑删除以下行，或完全量化它应该隐藏的命名空间，以免与您自己的冲突。

-keep class com.** { *; }
-keep interface com.** { *; }

更新：

您还保留了所有扩展 Activity、Fragments 等的类。这很可能是您编写的每一页代码。

# Keep fragments
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.app.Fragment

-keep public class * extends android.app.Activity
-keep public class * extends android.support.v7.app.ActionBarActivity
-keep public class * extends android.app.Application 

这不太可能有充分的理由。尝试删除上述内容。
