Quickblox 和 Pro Guard 错误

Question

我正在开发一个使用 Quickblox SDK 的应用程序。如果我用

编译它

minifyEnabled false

它工作得很好。但是，如果我启用 minify 来混淆代码，我会收到以下错误：

09-15 15:00:50.865  12029-12029/com.app.meet E/AndroidRuntime﹕ FATAL EXCEPTION: main

 Caused by: java.lang.IllegalStateException: java.lang.ClassNotFoundException: org.jivesoftware.smack.initializer.VmArgInitializer
        at c.b.a.q.<clinit>(Unknown Source)

我注意到 org.jivesoftware.smack 包在 quickblox-android-sdk-chat-2.3.1.jar 中

通过阅读网站上的一些答案，我修改了我的 proguard-rules.pro，如下所示：

#QuickBlox
-keep class org.jivesoftware.smack.initializer.VmArgInitializer { public *; }
-keep class org.jivesoftware.smack.ReconnectionManager { public *; }
-keep class com.quickblox.module.c.a.c { public *; }
-keep class com.quickblox.module.chat.QBChatService { public *; }
-keep class com.quickblox.module.chat.QBChatService.loginWithUser { public *; }
-keep class com.quickblox.module.chat.listeners.SessionCallback { public *; }
-keep class * extends org.jivesoftware.smack { public *; }
-keep class org.jivesoftware.smack.** { public *; }
-keep class org.jivesoftware.smackx.** { public *; }
-keep class com.quickblox.** { public *; }
-keep class * extends org.jivesoftware.smack { public *; }
-keep class * implements org.jivesoftware.smack.debugger.SmackDebugger { public *; }

我希望有人知道这里可能存在什么问题。

Answer 2

上面的答案不适用于我的情况下 quickblox 视频通话，应用程序一次又一次崩溃然后我尝试了另一个有效的专业保护规则。

转到应用程序中的 proguard-rules.pro(app) 文件并复制并粘贴到所有行下方。它的工作

##---------------Begin: proguard configuration for Gson  ----------
# Gson uses generic type information stored in a class file when working 
with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature

# For using GSON @Expose annotation
-keepattributes *Annotation*

# Gson specific classes
-keep class sun.misc.Unsafe { *; }
#-keep class com.google.gson.stream.** { *; }

# Application classes that will be serialized/deserialized over Gson
-keep class com.quickblox.core.account.model.** { *; }
