android - Proguard 与应用内购买 "Duplicate zip entry"错误

Question

我正在使用包含文件的应用内计费(按照developer.android.com执行步骤) InAppBillingService.aidl

按照此处的建议 -> http://developer.android.com/google/play/billing/billing_best_practices.html 出于安全原因，我们需要使用 Progaurd 来混淆代码。

现在导出启用了 proguard 的签名 apk 会出现以下错误。

重复的邮政编码条目 [android_6861407322325970495.jar:com/android/vending/billing/IInAppBillingService$Stub$Proxy.class]

任何想法/建议将不胜感激。 谢谢

也许这对你有帮助，

根据 ProGuard 文档:

Warning: can't write resource ... Duplicate zip entry Your input jars contain multiple resource files with the same name. ProGuard continues copying the resource files as usual, skipping any files with previously used names. Once more, the warning may be an indication of some problem though, so it's advisable to remove the duplicates. A convenient way to do so is by specifying filters on the input jars. There is no option to switch off these warnings.

您的库 jar android_6558830429113811056.jar 中有重复的资源条目“IInAppBillingService$Stub$Proxy.class”

您可以尝试使用-outjars

-outjars class_path Specifies the names of the output jars (or wars, ears, zips, or directories). The processed input of the preceding -injars options will be written to the named jars. This allows you to collect the contents of groups of input jars into corresponding groups of output jars. In addition, the output entries can be filtered, as explained in the filters section. Each processed class file or resource file is then written to the first output entry with a matching filter, within the group of output jars.

You must avoid letting the output files overwrite any input files. For better readability, class path entries can be specified using multiple -outjars options. Without any -outjars options, no jars will be written.

或者如果您使用-injars，您可以配置 filter
