I'm developing an app that uses the Quickblox SDK. If I compile it with
minifyEnabled false
It work's fine. But if I enable minify to obfuscate the code I get the following error:
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

I noticed that the org.jivesoftware.smack package is inside quickblox-android-sdk-chat-2.3.1.jar
By reading some answers in the site I modified my proguard-rules.pro like this:
#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 *; }
I hope someone has an idea of what might be the problem here.
These are the proguard rules that got it working. Hope it helps someone.
