【问题描述】：

我最近从 Eclipse 转到了 android Studios。我的应用程序通过 eclipse 使用 Proguard，现在我已经移动了，我遇到了以下错误。

错误：

# Note that you cannot just include these flags in your own

【问题讨论】：

类似：***.com/questions/18646899/…

【参考方案1】：

对于“Picasso”库，您只需将其添加到您的 ProGuard 配置中：

-dontwarn com.squareup.okhttp.**

这是因为“毕加索”有一个名为“OkHttp”的可选库。这不包括在内，但也不需要。

对于 Google Play 服务，似乎与库有些不一致。您应该更新您的库文件并清理项目。

【讨论】：

库是做什么用的？希望它不会导致任何 ClassNotFoundExceptions

OkHttp 是另一种 HTTP 客户端，可以代替 Android 或 Java 的内置客户端。所以你绝对不需要它，它不会导致任何ClassNotFoundExceptions。我也在使用没有 OkHttp 的 Picasso。更多关于 OkHttp：corner.squareup.com/2013/05/announcing-okhttp.html

【参考方案2】：

我最终输入了以下几行，因此 Proguard 停止警告我。构建仍按预期运行。

-dontwarn com.google.android.gms.auth.GoogleAuthUtil
-dontwarn com.squareup.picasso.OkHttpLoader

【讨论】：

您真的应该接受另一个答案，并且可能添加了有关您添加的额外行的评论。

我个人尝试使用通配符来尽可能少地忽略警告。我同意 Marco W. 的答案是一个很好的答案，我投了赞成票。但是，我的答案中提供了我使用的代码，这就是为什么我接受它作为我的问题的答案。
