使用kotlin的Branch Deep Link在Android设备上不起作用

如何解决使用kotlin的Branch Deep Link在Android设备上不起作用

我用kotlin创建了一个Android应用，正在集成Branch IO进行应用共享。我已经在Branch的帮助下使用以下代码实现了共享URL功能：

share.setOnClickListener {
        val lp = LinkProperties()
        val message = "Check out this product"
        val ss = ShareSheetStyle(this,"App",message)
            .setAsFullWidthStyle(true)
            .setSharingTitle("Share With")

        val image = productData.mainImage
        val url = this.getString(R.string.image_URL) + image
        buo = Utility(this).prepareSharingLink(
            productData.id.toString(),"product",url,UtilityTools.getInstance().getValue(productData.name)
        )
        buo.showShareSheet(this,lp,ss,object : BranchLinkShareListener {
            override fun onShareLinkDialogLaunched() {}
            override fun onShareLinkDialogDismissed() {}
            override fun onLinkShareResponse(
                sharedLink: String,sharedChannel: String,error: BranchError?
            ) {
                val metaData: HashMap<String,String> = HashMap()
                if (error == null) {
                    metaData[Defines.Jsonkey.SharedLink.key] = sharedLink
                } else {
                    metaData[Defines.Jsonkey.ShareError.key] = error.message
                }
            }

            override fun onChannelSelected(channelName: String) {}
        })

    }

prepareSharingLink是如下功能：

 fun prepareSharingLink(
        itemID: String,itemType: String,imageURL: String?,customTitle: String = ""
    ): BranchUniversalObject {

        val canonical = itemType.plus("/").plus(itemID)
        var branchUniversalObject = BranchUniversalObject()
        branchUniversalObject.canonicalIdentifier = canonical
        branchUniversalObject.title = customTitle
        branchUniversalObject.setContentDescription("")
        branchUniversalObject.setContentImageUrl(imageURL!!)
        branchUniversalObject.contentMetadata.customMetadata["itemType"] = itemType
        branchUniversalObject.contentMetadata.customMetadata["itemID"] = itemID
        branchUniversalObject.isLocallyIndexable
        branchUniversalObject.isPublicallyIndexable
        branchUniversalObject.setContentIndexingMode(BranchUniversalObject.CONTENT_INDEX_MODE.PRIVATE)
        return branchUniversalObject
    }

当我单击UI中的“共享”按钮，然后选择“复制到剪贴板”时，然后单击“粘贴”时，没有URL复制。 我想知道应该如何更改代码以复制URL。
