我已经将项目升级到实际的Android构建环境。在工作之前。现在，我在Gradele assembleRelease中遇到错误。
在日志中，我得到很多注释，然后得到2条警告，我认为这会导致失败。
我的问题是，我现在不知道有10个未解析的对类或接口的引用，或者5个依赖于程序类的库类实例的含义。
Note: there were 1 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 25 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 10 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 5 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.

Warning: Exception while processing task java.io.IOException: Please correct the above warnings first.
