@sushant-nga,

Looks like you are using proguard and have not added the proguard configuration for kommunicate.
Can you add the below configurations in your proguard-rules.pro file and try?

#keep JSON classes                
-keepclassmembernames class * extends com.applozic.mobicommons.json.JsonMarker {
    !static !transient <fields>;
}

-keepclassmembernames class * extends com.applozic.mobicommons.json.JsonParcelableMarker {
    !static !transient <fields>;
}

#GSON Config          
-keepattributes Signature          
-keep class sun.misc.Unsafe { *; }           
-keep class com.google.gson.examples.android.model.** { *; }            
-keep class org.eclipse.paho.client.mqttv3.logging.JSR47Logger { *; } 
-keep class android.support.** { *; }
-keep interface android.support.** { *; }
-dontwarn android.support.v4.**
-keep public class com.google.android.gms.* { public *; }
-dontwarn com.google.android.gms.**
-keep class com.google.gson.** { *; }

Thanks buddy...didn't see that. Now it's working fine.
