【中文标题】分支 IO 随机应用程序崩溃 - Kotlin【英文标题】：Branch IO random App crash - Kotlin 【发布时间】：2018-05-09 13:04:59 【问题描述】：我正在为我的应用程序中的应用程序共享集成 Branch IO。我在 Branch 的帮助下使用以下代码实现了共享 URL 功能：
fun ShareApp()
val appShare = BranchUniversalObject()
.setCanonicalIdentifier("app-share")
.setTitle(resources.getString(R.string.app_name))
.setContentImageUrl(AppConstants.AppIconURL)
.setContentIndexingMode(BranchUniversalObject.CONTENT_INDEX_MODE.PUBLIC)
val lp = LinkProperties()
.setChannel("facebook")
.setFeature("sharing")
val ss = ShareSheetStyle(this, appName, Message)
.setAsFullWidthStyle(true)
.setSharingTitle("Share With")
appShare.showShareSheet(this, lp, ss, object : Branch.BranchLinkShareListener
override fun onShareLinkDialogLaunched()
override fun onShareLinkDialogDismissed()
override fun onLinkShareResponse(sharedLink: String, sharedChannel: String, error: BranchError)
override fun onChannelSelected(channelName: String)
)
每当我点击任何频道时说 Whatsapp，有时它会起作用并将我带到 whatsapp。但是很多时候频道没有被选中，它给了我下面的崩溃：

大多数情况下，它最终会因未选择频道名称而崩溃。执行中有什么问题吗？
谢谢
【问题讨论】：
【参考方案1】：为避免崩溃，请使用此签名：
override fun onLinkShareResponse(
sharedLink: String?,
sharedChannel: String?,
error: BranchError?)
然后您可以检查什么是 null 而不是获取低级异常。
我在 Branch 的网站上看到了代码，Kotlin 示例看起来很糟糕。我认为error 始终为非空是没有意义的，即使没有错误也是如此。 sharedChannel 在出错的情况下可能为空。
【讨论】：
来自分支机构的亚伦。 @Siraj，你能试试这个吗？如果这可以处理这种情况，我们当然可以更新文档以确保它适用于 Kotlin。 如果您不介意，您还应该从 Kotlin 示例中删除new 关键字。它在 Kotlin 中不存在。以上是关于分支 IO 随机应用程序崩溃 - Kotlin的主要内容，如果未能解决你的问题，请参考以下文章
