ProGuard和RoboGuice带@Inject注解问题

我在优化我的android应用时遇到了一些proguard问题。似乎有一些注释类（@ com.google.inject.Inject）对Dalvik/Harmony在运行时不满意。ProGuard和RoboGuice带@Inject注解问题

java.lang.annotation.IncompleteAnnotationException： 可选元素是不完整的的注释 com.google.inject.Inject

com.google.inject.Inject样子这个（吉斯的部分）：

@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; 
}

下面是关于发射失败的原因：

看起来不像你保持注解。由于它们对代码的执行没有任何影响，因此它们将被完全剥离出来，而这真的很糟糕，因为唯一的检索方法就是反射。

尝试增加

-keepattributes *Annotation*

马克明确地保持各种运行时的注释，而不是AnnotationDefault属性。这可能会导致异常。添加它或使用通配符的确可以解决问题。 – 2011-04-07 21:48:35

谢谢，就是这样！ – 2011-04-08 00:28:04

我发现使用-keepattributes * – 2012-04-17 19:19:21

要获得RoboGuice 2为我工作，我不得不添加下面的什么，我已经有了：

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

，并与来自非优化的版本运行SDK。我的project.properties如下。请注意，它是proguard-android.txt而不是proguard-android-optimization.txt，后跟一个冒号字符和我的自定义proguard.cfg，它位于我的项目根目录中。

/project.properties: 

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

我的最后一个，这可能是更安全比我更需要：

/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

更安全这几乎使我的代码工作！添加'-dontwarn javax.inject.Singleton'后，它真的是我的工作！ Thx to @Jon Adams – acntwww 2013-08-16 07:14:10

@acntwww：我从来没有'@ Singleton'为我工作可靠，所以在我的ProGuard中我不需要这个选项。你不会想在文档或博客上写下你是如何获得@Singleton的工作？ – 2013-08-16 19:43:27

我真的很抱歉没有说清楚我的话。我的意思是有一个与javax.inject.Singleton相关的警告，所以我只是写了这个。另一件事是：我是roboguice的新手。 – acntwww 2013-08-20 09:57:31
