安卓:配置混淆器

Question

我正在尝试配置混淆器并遇到了一些按优先级排序的问题:

• 我收到了重复 zip 的警告并且无法修复它。我在“libs”目录中使用外部库和 2 个库项目(一个库项目有一个外部库 - 仅添加到项目一次)仅添加到项目一次。我试图将我的外部 jars 移动到另一个目录，即“lib”——只是重命名，因为一些用户已经设法解决了这个问题，但这对我没有帮助。另一种方法是尝试将 custom_rules 实现到基本的 build.xml，因为它可以帮助一些用户避免这些警告。但是它的一切都对我没有帮助，我该如何解决？日志:

  ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [jackson-annotations-2.1.4.jar:META-INF/MANIFEST.MF])
  ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [android-support-v4.jar:META-INF/MANIFEST.MF])
  ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [google-analytics-v2.jar:META-INF/MANIFEST.MF])
  ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [jackson-core-2.1.4.jar:META-INF/MANIFEST.MF])
  ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [httpclientandroidlib-1.1.2.jar:META-INF/MANIFEST.MF])
  ProGuard: Warning: can't write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [deviceprint-lib-1.0.0.jar:META-INF/MANIFEST.MF])
  

• 最后一件事是签名 apk 构建过程中的一些注意事项:

  ProGuard: Note: com.google.analytics.tracking.android.AdHitIdGenerator: can't find dynamically referenced class com.google.ads.AdRequest
  ProGuard: Note: the configuration refers to the unknown class 'com.google.vending.licensing.ILicensingService'
  ProGuard: Note: the configuration refers to the unknown class 'com.android.vending.licensing.ILicensingService'

您当前列出的 6 条警告和 3 条注意事项是无害的。

您应该确保您使用的是最新版本的 Android SDK，它会为您的项目创建一个空的 proguard-project.txt。标准的 Ant 构建和 Eclipse 构建在内部负责重要的配置(我假设您使用的是 IDEA 中的 Ant)。您仍然可以将特定于应用程序的选项添加到 proguard-project.txt，例如 Jackson 和 ActionBarSherlock 的 -keep 选项。不要添加诸如 -injars/-libraryjars/-outjars 之类的选项，因为构建过程会为您指定它们。
