EkoJitsiPluginActivity.kt(224,28)：型別不匹配：推斷型別是字串？但字串是預期的-有解無憂

當我想構建時，Eco Jitsi 插件會產生問題。它向我展示了這種型別的錯誤

想要構建時會產生問題，但是當使用顫振運行時就可以了。我怎么解決這個問題？

uj5u.com熱心網友回復：

在您的錯誤訊息EkoJitsiPluginActivity.kt (224, 28)中， 224 是指行號。這樣你就可以找出錯誤在哪里。如果我沒記錯的話，那應該在上面寫著

wv.loadUrl(whiteboardUrl)

loadUrl需要一個String但是whiteboardUrl是一個String?。要將其推廣為String您可以撰寫的

wv.loadUrl(whiteboardUrl!!)
