在启用proguard的发布模式下编译Android应用程序时出现问题

我试图用proguard编译我的Android应用程序，但我遇到了以下错误，不知道如何修复它们。有人知道吗？在调试模式下，一切都可以正常编译

            Note: there were 2 references to unknown classes.
                  You should check your configuration for typos.
                  (http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass)
            Note: there were 112 library classes explicitly being kept.
                  You don't need to keep library classes; they are already left unchanged.
                  (http://proguard.sourceforge.net/manual/troubleshooting.html#libraryclass)
            Note: there were 16 unresolved dynamic references to classes or interfaces.
                  You should check if you need to specify additional program jars.
                  (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclass)
            Note: there were 4 accesses to class members by means of introspection.
                  You should consider explicitly keeping the mentioned class members
                  (using '-keep' or '-keepclassmembers').
                  (http://proguard.sourceforge.net/manual/troubleshooting.html#dynamicalclassmember)
            Warning:there were 146 instances of library classes depending on program classes.
                     You must avoid such dependencies, since the program classes will
                     be processed, while the library classes will remain unchanged.

与

已修复此问题。

在proguard-rules.pro文件中添加以下行

-keep class android.support.v4.** { *; }
-dontnote android.support.v4.**

---

你为什么要应用

com.google.gms.google服务

plugin？因为谷歌分析需要这个。请参阅“谢谢”链接，出于好奇问：）可能是这个和这个可以帮助您。不是真的，因为它没有解释排除哪些软件包或模块这对我有帮助。

-keep class android.support.v4.** { *; }
-dontnote android.support.v4.**
