项目是kotlin的app, 集成uikit后, 原来的App类添加如下uikit初始化代码(init报错)

class App : MultiDexApplication() {     override fun onCreate() {

        ...

        override fun onCreate() {

        //IM relate        // 只在主进程初始化，否则会导致重复收到消息        if (getCurProcessName(this) == BuildConfig._APPLICATIONID) {             // 如果uikit是以aar的方式引入 ，那么需要在此对Config里面的属性进行配置，如：            // Config.IM_SERVER_HOST = "im.example.com"; 

          val wfcUIKit = WfcUIKit.getWfcUIKit()           wfcUIKit.init(this)           wfcUIKit.appServiceProvider = AppService.Instance()          //PushService.init(this, BuildConfig.APPLICATION_ID)           MessageViewHolderManager.getInstance().registerMessageViewHolder(            LocationMessageContentViewHolder::class.java,            R.layout._conversation_item_locationsend,            R.layout._conversation_item_locationsend )            setupWFCDirs() }

    }
