android - Proguard 和 Scoreloop

Question

我正在尝试在我的 Android 项目上使用 Proguard，但在 Scoreloop(3.0.3 版)库的运行时不断出现相同的错误...

我在 project.properties 文件中定义了 proguard 配置文件:

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……):

# Note: if you are removing log messages elsewhere in this file then this isn't necessary
-keep class org.acra.ACRA {*;}

# keep this around for some enums and classes that ACRA needs
-keep class org.acra.ReportingInteractionMode {*;}

我在运行时遇到这个错误:

Caused by: java.lang.IllegalArgumentException: java.lang.NoSuchMethodException: <init> [class com.scoreloop.client.android.core.b.aw]

    at com.scoreloop.client.android.core.b.j.a(SourceFile:684)

从文件 mapping.txt 中，我发现了有关有问题的类和调用的信息:

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:
[...]

所以我认为错误是说它找不到接受Session的Client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.**

运气不好，现在我收到了这个错误:

Caused by: java.lang.IllegalArgumentException: java.lang.NoSuchMethodException: <init> [class com.scoreloop.client.android.core.model.Session]
    at com.scoreloop.client.android.core.model.Client.a(SourceFile:692)
    at com.scoreloop.client.android.core.model.Client.a(SourceFile:605)
    at com.scoreloop.client.android.core.model.Client.<init>(SourceFile:368)

    at com.scoreloop.client.android.core.model.Client.a(SourceFile:684)

现在我对接下来要尝试的事情有点迷茫......关于这个错误的任何想法和启示？

在得到 Scoreloop 支持的响应和我这边的一些测试后，这里是 Scoreloop 的 ProGuard 配置:

# ######### #
# Scoreloop #
# ######### #
-dontwarn com.scoreloop.client.android.core.paymentprovider.**
-keep class com.scoreloop.client.android.core.paymentprovider.fortumo.FortumoPaymentProviderController {*;}
-keep class com.scoreloop.client.android.core.paymentprovider.fortumo.FortumoPaymentProvider {*;}
-keep class com.scoreloop.client.android.core.paymentprovider.paypalx.PayPalXPaymentProviderController {*;}
-dontwarn com.scoreloop.client.android.core.ui.WebViewDialog
-keep class com.scoreloop.client.android.core.ui.WebViewDialog {*;}
-keep class com.facebook.android.** {*;}
-keep class com.scoreloop.client.android.core.** { *; }
