因此，我们已经到了 Android 游戏开发的最后阶段，是时候对 Proguard 进行一些混淆了。

我们的游戏使用 Greystripe 广告，编译调试版本时一切正常，针对 API 7。

但是在编译发布版本时（在过程中添加了 Proguard），有很多警告：

     You may need to specify additional library jars (using '-libraryjars').

所以很明显我开始尝试很多不同的变化-keep class等等-keep public class，但没有任何效果。然后我开始大量使用谷歌搜索，发现大量论坛帖子中人们都有同样的问题，我尝试了人们回复的所有建议。还是没有变化。

然后我查看了android.jar，发现android.webkit.JavascriptInterface在API 17之前没有引入，然后它当然是有道理的。因为我的目标是 API 7，所以自然没有android.webkit.JavascriptInterface可用的。

但我不想仅仅因为广告而定位 API 17，而且我很确定我也不应该这样做。

从逻辑上讲，我认为我应该能够做到-dontwarn，但这样做会导致应用程序在加载时崩溃。

我当然确保我放了-libraryjars /path/to/libs/greystripe-android-sdk-2.3.0.jar而且/path/to/android.jar

有人对此有任何线索吗？如何混淆我的应用程序，同时不理会 graystripe-sdk jar？

ProGuard 在读取输入后立即打印这些警告，因此-keep选项无济于事。您应该针对 API 17 进行构建，以便 ProGuard 可以找到分析和处理您的应用程序所需的所有类。您仍然可以在 AndroidManifest.xml 中指定不同的目标。

如果您使用的是标准的 Ant/Eclipse/Gradle 构建，则不应指定-libraryjars，因为这些构建已经为您完成了这项工作。

将以下内容添加到您的 ProGuard 文件中：

-keep class com.greystripe.** { *; }

这应该会删除警告并允许 Greystripe SDK 按预期运行。

如果由于某种原因该行无法修复它，请尝试以下操作：

-keep class com.greystripe.** { *; }

-keepclassmembers class com.greystripe.** { public *; }

虽然我现在没有时间测试这个（我还有很多其他的事情要做），但我想趁它还记忆犹新的时候把它写在这里。然后我们将看看它是否会成为以后的解决方案。

要记住的重要一点：targetSdkVersion 与构建版本不同。

在这种情况下，使用 Greystripe 类，它们显然会测试某些仅在 API 17 之后才可用的 Android 类的存在，您应该将构建目标设置为 API 17。这意味着您将使用 API 17 中可用的类进行编译. Proguard因此不应该给出警告。

不过，在您的 AndroidManifest.xml 文件中，您不一定必须输入 targetSdkVersion="17"。您可以将其设置为您希望的任何目标。（尽管由于 ICS 和菜单按钮问题，建议始终以 API 14 或更高版本为目标）。

所以现在的最优设置（理论上，以后还要测试），就是设置

build target = API 17 - 避免 Proguard 警告，因为 Greystripe API 引用 API 17 sdkTargetVersion >= 14 中的类 - 因为兼容性问题。将其设置为您能够在 minTargetVersion = 7 上测试的 API 版本（如果您的应用程序将在 API 7 上运行） - 因为根据文档，Greystripe API 应该在 API 7 上运行

然后一切都应该工作。
