Note: there were 1 references to unknown classes.
You should check your configuration for typos.
(http://proguard.sourceforge.net/manual/troubleshooting.html#unknownclass)
Note: there were 2 references to unknown class members.
You should check your configuration for typos.
Note: there were 22 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 41 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 18 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 4 unresolved references to library class members.
You probably need to update the library versions.

:app:transformClassesAndResourcesWithProguardForDebug FAILED`enter code here`
因此在proguard-rules.pro中添加了以下规则，因此我看不到任何错误，但是在应用运行时会看到崩溃。
-dontwarn okio.**
-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**
下面提到的导致运行该应用程序时崩溃的错误，对于ProGuard来说我是一个新手，所以请帮助我修改ProGuard规则以解决此崩溃。
