我正在尝试在我的 Android 项目上使用 Proguard，并在运行时在 Scoreloop（版本 3.0.3）库上不断收到相同的错误...
我在 project.properties 文件中定义了 proguard 配置文件，如下所示：
proguard.config=${sdk.dir}/tools/proguard/proguard-android-optimize.txt:proguard-project.txt
proguard.enabled=true
这是我的 proguard-project.txt 文件（包含所有内容，以防我在某处做错了什么......）：

我在运行时收到此错误：

从文件 mapping.txt 中，我发现了关于有问题的类和调用：
com.scoreloop.client.android.core.model.Client -> com.scoreloop.client.android.core.b.j:
java.util.Map a -> a
com.scoreloop.client.android.core.model.ClientObserver b -> b
com.scoreloop.client.android.core.model.Session c -> c
103:104:boolean a(java.util.Properties,java.lang.String,boolean) -> a
155:178:java.util.Properties a(android.content.Context) -> a
182:185:void a(java.util.Properties,java.lang.String) -> a
188:194:void a(java.util.Properties,java.lang.String,java.lang.String) -> a
198:232:void a(android.content.Context,java.lang.String) -> a
380:387:void a(java.util.Properties) -> a
638:640:int b(java.util.Properties,java.lang.String) -> b
684:692:void a(java.lang.Class) -> a
708:711:void a$2a1b557e(com.scoreloop.client.android.core.model.Session) -> a
715:718:boolean a(com.scoreloop.client.android.core.model.Session) -> b
722:723:void b(android.content.Context) -> b
[...]
com.scoreloop.client.android.core.model.Session -> com.scoreloop.client.android.core.b.aw:
[...]
所以我以为报错说找不到Client接受Session的构造函数。我尝试将以下内容添加到我的 proguard conf 中：
-keep class com.scoreloop.client.android.core.model.** {*;}
-keepclassmembers class com.scoreloop.client.android.core.model.**
没有运气，现在我收到了这个错误：

现在我对接下来要尝试什么有点迷失了......关于这个错误的任何想法和启示？
