Mobclix和Proguard

Question

我正在尝试使用Proguard来混淆我的代码。我使用Mobclix做广告，当我构建我的APK时，它会显示一个错误：

org.eclipse.core.runtime.CoreException: Proguard returned with error code 1. See console

         You may need to specify additional library jars (using '-libraryjars'), 
         or perhaps the '-dontskipnonpubliclibraryclasses' option.

现在，我已经将他们文档中的Mobclix推荐位放到了我的proguard.cfg中：

-keep public class com.mobclix.android.sdk.*
-keep class com.mobclix.android.sdk.MobclixJavascriptInterface

-keepclassmembers class com.mobclix.android.sdk.MobclixJavascriptInterface
{
    public void *(...);
    <methods>;
}

-keepclassmembernames class
com.mobclix.android.sdk.MobclixJavascriptInterface {
    public void *(...);
    <methods>;
}

还有什么我应该做的吗？万分感谢

Answer 1

这些消息解释说，一些Mobclix类(如com.mobclix.android.sdk.MobclixContactsCursorEntityIterator)依赖于Android运行时类(如android.content.Entity)，而这些类并不存在于您的输入jars或库jars中。通常，这可能是一个严重问题的迹象:如果这部分代码被执行，它将会因为NoClassDefFoundError而失败(即使没有混淆)。

看起来实体类是在Android SDK7中引入的，所以我假设您是在一个较旧的SDK上构建的。同样，假设您的代码可以正常运行，尽管缺少这个类，您可以让ProGuard接受与

-dontwarn android.content.Entity*

请注意，-keep选项在这里不起作用。在考虑任何-keep选项之前，ProGuard会执行一致性检查。

另请参阅ProGuard manual > Troubleshooting > Warning:找不到引用的类

Answer 2

也许会有所改变

-keep public class com.mobclix.android.sdk.*

至

-keep public class com.mobclix.android.sdk.**
