问题描述
当在chrome:/inspect#devices中或者直接在android studio中调试我的应用的web部分时，我可以看到我被 "Notifying Native Hook "的消息淹没了.当使用chrome:/inspect#devices来检查应用中使用的web页面时，我看到消息的源头是VM298:5（很确定我看到它在VM后面也有其他数字）。当点击源码时，我发现有以下功能。
(function () {
if (document.readyState === "complete") {
var foundMessageBridge = false
function notifyMessageBridge() {
console.log("Notifying Native Hook")
if (window.__KlarnaNativeHook != null) {
console.log("Klarna Native Hook was notified")
window.__KlarnaNativeHook.setNativeReady()
foundMessageBridge = true
} else {
window.setTimeout(notifyMessageBridge, 500)
}
}
notifyMessageBridge()
}
window.addEventListener('load', () => {
let interval = null
let notifyMessageBridge = () => {
if (window.__KlarnaNativeHook != null) {
window.__KlarnaNativeHook.setNativeReady()
clearInterval(interval)
}
}
interval = setInterval(notifyMessageBridge, 500)
})
}())
这终于让我想到，它与Klarna有关。由于我被这个淹没了，我想我的应用没有进入if (window.__KlarnaNativeHook != null)。
经过一些调试，我注意到了以下情况。
(activity as MainActivity).klarnaHybridSDK.addWebView(myWebView) 信息淹没停止。我想这并不奇怪。我不知道这是SDK的bug还是我的错误。
有什么建议可以阻止 "通知Native Hook "的垃圾信息吗（我知道怎么过滤，但是120条信息分*（我的app的网页+生成的无标题），而且每次都要做，实在是太烦了

Klarna In-App SDK版本：com.klarna.mobile:sdk:2.0.16。
首先，感谢你报告这个问题。幸运的是，这个问题将在未来的版本中得到修复。
为了让您了解更多，目前的问题是当SDK试图在没有内容的WebView中通知Klarna组件时；从而导致一个名为 "untitled "的页面出现过多的日志。
暂时可以通过在加载页面时将WebView添加到Hybrid SDK中来避免这个问题。
编辑：@Myalakin @Myalakin 我们想告诉你，这个问题已经在我们最新发布的SDK中得到了修复。
