在android库项目中停止proguard破坏性注释

Question

我在我的游戏中使用 GREE sdk 来处理社交内容。在导出签名的 apk 时，proguard 弄乱了 GREE sdk 中的一些自定义注释。 （我在游戏中使用 GREE sdk 作为库项目）

如果我不向 proguard 配置添加任何内容。它也会混淆 GREE SDK，当我尝试安装和运行游戏时，它会抛出“注入（gree sdk 中的自定义注释）”缺少注释异常。

首先我添加了这个 keep 语句来跳过整个 GREE SDK 的混淆。

-keep class net.gree.** {
  public protected private *;
}

这帮助我避免了 sdk 代码被混淆，但“注释”仍然被删除，我仍然收到同样的异常。

然后我尝试一一添加-keepattributes 语句，但没有一个对我有帮助。

a) -keepattributes *Annotation*
b) -keepattributes Inject
c) -keepattributes net.gree.asdk.core.inject.Inject
d) -keepattributes @net.gree.asdk.core.inject.Inject

(d) 选项抛出找不到文件/CLASSPATH OF PRJECT/net.gree.asdk.core.inject.Inject

这是我的 proguard 配置文件：

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-keepattributes *Annotation*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService

-dontwarn org.mockito.cglib.**
-dontwarn sun.reflect.**
-dontwarn android.test.**


-keepclasseswithmembernames class * {
    native <methods>;
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-keep class net.gree.** {
  public protected private *;
}

我试图摆脱的异常：

Answer 1

您应该在 proguard 文件中添加一些配置，以使用 Inject 注释保留带注释的类（构造函数和字段）：

 # keeps all fields and Constructors with @Inject
 -keepclassmembers,allowobfuscation class * {
    @com.google.inject.Inject <fields>;
    @com.google.inject.Inject <init>(...);
 }

Answer 2

这对我有用

################### GREE SDK ##################
-keepclassmembers,allowobfuscation class * {
    @net.gree.asdk.core.inject.Inject <fields>;
    @net.gree.asdk.core.inject.Inject <init>(...);
}


##################### GSON #####################
-keepattributes Signature
-keep class sun.misc.Unsafe { *; }

 # Model classes parsed by GSON
-keep class net.gree.asdk.** {
    public protected private *;
}

它类似于另一个响应，但使用了 GREE 特定的注释。

Answer 3

而不是这样做 -keep class net.gree.** { 公共保护私人*； }

我不得不这样做

-keep class net.gree.** {
   *;
}
