Question

在优化我的Android应用程序时，我遇到了一些proguard问题。似乎对注释类（@ com.google.inject.Inject）做了一些事情，Dalvik / Harmony在运行时不满意。

java.lang.annotation.IncompleteAnnotationException： 可选元素不完整用于注释 com.google.inject.Inject

com.google.inject.Inject看起来像这样（Guice的一部分）：

@Target(value={ElementType.METHOD, ElementType.CONSTRUCTOR, ElementType.FIELD})
@Retention(value=java.lang.annotation.RetentionPolicy.RUNTIME)
@Documented
public abstract @interface com.google.inject.Inject extends Annotation {
  public abstract boolean optional() default false;
}

这是发布失败的原因：

Answer 1

看起来不像是在保留注释。它们将被完全剥离，因为它们对代码的执行没有影响，而这真的很糟糕，因为检索的唯一方法是使用反射。

尝试添加

-keepattributes *Annotation*

Answer 2

为了让RoboGuice 2为我工作，我必须将以下内容添加到我已经拥有的内容中：

-keep class com.google.inject.** { *; } 
-keep class javax.inject.** { *; } 
-keep class javax.annotation.** { *; } 
-keep class roboguice.** { *; }

使用SDK中的非优化版本运行它。我的project.properties紧随其后。请注意，proguard-android.txt 不是 proguard-android-optimization.txt，后跟冒号字符和我的项目根目录中的自定义proguard.cfg。

/project.properties:

# ProGuard configuration
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard.cfg

我的决赛，这可能比我需要的更安全：

/proguard.cfg:

-keepattributes Signature
-keepattributes *Annotation*
-keep class roboguice.**

# if not using Google Maps library, safe to ignore these
-dontwarn roboguice.activity.RoboMapActivity
# safe to ignore testing classes, when proguard not being run against an instrumentation testing app
-dontwarn roboguice.test.**

-keep class com.google.inject.** { *; } 
-keepclassmembers class * {
    @com.google.inject.Inject <fields>;
    @com.google.inject.Inject <init>(...);
}
-keep class javax.inject.** { *; } 
-keep class javax.annotation.** { *; } 

# My application classes used by injection framework
-keep class com.myapp.RoboGuiceModule { *; }
-keep class com.myapp.AppProvider { *; }
-keep class com.myapp.MyInjectableSingletonExample { *; }
# ... other classes that are referenced in my custom RoboGuiceModule.configure() bindings

带有@Inject注释的ProGuard和RoboGuice问题
