我最近从 Eclipse 转到了 Android Studios。我让我的应用程序通过 eclipse 使用 Proguard，现在我已经跨过了，我遇到了以下错误。

错误:

-dontoptimize

# -allowaccessmodification
#
# Note that you cannot just include these flags in your own
# configuration file; if you are including this file, optimization
# will be turned off. You'll need to either edit this file, or
# duplicate the contents of this file and remove the include of this
# file from your project's proguard.config path property.

最佳答案

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“Picasso”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，似乎与图书馆有些不一致。您应该更新库文件并清理项目。
