Mobclix 和 Proguard

Question

我正在尝试使用 Proguard 来混淆我的代码。我使用 Mobclix 进行广告，当我构建 APK 时，它会抛出一个错误：

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

现在，我已将其文档中的 Mobclix 推荐位放入我的 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>;
}

我还应该做些什么吗？感谢一百万

Answer 1

这些消息解释了某些 Mobclix 类（例如 com.mobclix.android.sdk.MobclixContactsCursorEntityIterator）依赖于不存在的 Android 运行时类（例如 android.content.Entity）在您的输入 jar 或库 jar 中。一般来说，这可能是严重问题的征兆：如果这部分代码被执行，它将因 NoClassDefFoundError 失败（即使没有混淆）。

看起来 Entity 类已经在 Android SDK 7 中引入了，所以我假设您正在针对较旧的 SDK 进行构建。再次假设尽管缺少这个类，您的代码仍能正常运行，您可以让 ProGuard 接受有些不一致的输入，并

-dontwarn android.content.Entity*

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

另请参阅 ProGuard 手册 >故障排除>>警告：找不到引用的类

Answer 2

也许更改

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

为

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