Mobclix and Proguard

Question

我试图使用Proguard来混淆我的代码。我使用Mobclix广告，当我建立我的APK它吐出一个错误:

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

现在，我已经把Mobclix推荐位从他们的文档中放入我的proguard.cfg:

-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?Thanks a million

Answer 1

消息解释了一些Mobclix类(如com.mobclix.android.sdk.MobclixContactsCursorEntityIterator)依赖于Android运行时类(如android.content.Entity)，这些类不存在于您的输入jar或库jar中。一般来说，这可能是一个严重问题的迹象:如果这部分代码被执行，它将以NoClassDefFoundError失败(即使没有混淆)。

看起来Entity类已经在Android SDK 7中引入了，所以我假设你是基于旧的SDK构建的。再次假设您的代码在缺少这个类的情况下运行良好，您可以让ProGuard接受带有

的不一致输入。

-dontwarn android.content.Entity*

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

请参阅ProGuard手册>故障排除>警告:无法找到引用的类

Answer 2

可能会改变

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

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