我真的想在我的应用程序中使用这个Proguard功能,但是看到那千个警告让我想知道它是否值得…我应该添加什么才能使它成功构建？或者让我知道这是否是一个失败的原因……
这是我的Gradle文件：

(…)
Note: there were 4 references to unknown classes.
You should check your configuration for typos.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass)
Note: there were 11 classes trying to access enclosing classes using reflection.
You should consider keeping the inner classes attributes
(using '-keepattributes InnerClasses').
(http://proguard.sourceforge.net/manual/troubleshooting.html#attributes)
Note: there were 143 unkept descriptor classes in kept class members.
You should consider explicitly keeping the mentioned classes
(using '-keep').
(http://proguard.sourceforge.net/manual/troubleshooting.html#descriptorclass)
Note: there were 30 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)
Warning:there were 1911 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes,you can suppress
the warnings with '-dontwarn' options.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
Warning:there were 2 unresolved references to library class members.
You probably need to update the library versions.

解决方法
我通常需要告诉proguard保留第三方库以使其成功构建.例如,Id为Okio和fasterxml添加以下内容：
-keep class okio.** { *; }
-dontwarn okio.**
-keep class com.fasterxml.** { *; }
-dontwarn com.fasterxml.**
为项目中包含的每个第三方库添加上述内容.从你的日志我看到glassfish,jersey,squareup,google,Okio和fasterxml.
以下是有关上面列出的proguard规则的更多信息：
Android Proguard – is it best practice to -keep all 3rd party libs?
