android - KlarnaHybridSDK - 被“Notifying Native Hook”消息淹没 [ANDROID]

问题描述

问题描述

在 chrome://inspect/#devices 或直接在 android studio 中调试我的应用程序的 Web 部分时，我可以看到我被消息“Notifying Native Hook”淹没了。当使用 chrome://inspect/#devices 检查应用程序中使用的网页时，我看到该消息具有源 VM298:5（很确定我在 VM 之后也看到了另一个数字）。单击源时，我发现以下功能：

 (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)
     })
 }())

这最终让我意识到它与 Klarna 有关。由于我被这个淹没了，我想我的应用程序没有进入 if (window.__KlarnaNativeHook != null)。

经过一些调试后，我注意到以下内容：

当我开始与 Klarna 交互时，我的应用程序进入 if (window.__KlarnaNativeHook != null)。但只有一次，然后垃圾邮件就会恢复。
如果我删除该行(activity as MainActivity).klarnaHybridSDK.addWebView(myWebView)，则消息淹没停止。我想这并不奇怪。
除了我的应用程序的网页生成了空的无标题网页，它只在控制台中打印出“Notifying Native Hook”，没有别的，没有代码，什么都没有。
除了淹没之外，该应用程序与 Klarna 一起工作得很好。

我不确定这是 SDK 中的错误还是我的错误。

关于如何阻止垃圾邮件“Notifying Native Hook”的任何建议？（我知道如何过滤它，但是 120 条消息/分钟 *（我的应用程序的网页 + 生成的无标题）并且每次都这样做很累）

代码

主要活动

class MainActivity : AppCompatActivity(), KlarnaHybridSDKCallback {
...
    lateinit var klarnaHybridSDK : KlarnaHybridSDK
    override fun onCreate(savedInstanceState: Bundle?) {
        klarnaHybridSDK = KlarnaHybridSDK("myapp://", this)
        ...
    }
    override fun didHideFullscreenContent(webView: WebView, completion: OnCompletion) {
        Timber.i("Klarna didHideFullscreenContent called")
        completion.run()
    }

    override fun didShowFullscreenContent(webView: WebView, completion: OnCompletion) {
        Timber.i("Klarna didShowFullscreenContent called")
        completion.run()
    }

    override fun onErrorOccurred(webView: WebView, error: KlarnaMobileSDKError) {
        Timber.i("Klarna onErrorOccurred called")
        Timber.i("Klarna Error: $error")
    }

    override fun willHideFullscreenContent(webView: WebView, completion: OnCompletion) {
        Timber.i("Klarna willHideFullscreenContent called")
        completion.run()
    }

    override fun willShowFullscreenContent(webView: WebView, completion: OnCompletion) {
        Timber.i("Klarna willShowFullscreenContent called")
        completion.run()
    }
}

            }

            override fun onReceivedError(view: WebView?, request: WebResourceRequest?, error: WebResourceError?) {

                    //Added to prevent Klarna's address search failing to cause the app to show the error screen.
                    if (request?.url.toString().contains("klarna.com/eu/address")) {
                        Timber.i("${receivedError}")
                        Timber.i("Ignoring error since it's simply Klarna's address search failing")
                    }
                ...
            }
            @TargetApi(21)
            override fun shouldOverrideUrlLoading(view: WebView?, request: WebResourceRequest?): Boolean {
                val url = request?.url

                return (activity as MainActivity).klarnaHybridSDK.shouldFollowNavigation(url.toString())
            }

            /*To handle cases where the target API < 21*/
            override fun shouldOverrideUrlLoading(view: WebView?, url: String?): Boolean {
                return (activity as MainActivity).klarnaHybridSDK.shouldFollowNavigation(url.toString())
            }
        }
        val url = "myAppUrl.php"
        val postData = "data=" + URLEncoder.encode(data, "UTF-8").toString()
        myWebView.postUrl(url, postData.toByteArray())
         return root
    }
    ...
}

重现步骤

启动应用程序
在 Chrome 中打开 chrome://inspect/#devices。
定位到相关网页
按“检查”

预期行为

没有被我控制台中的消息淹没。

设备和版本：

设备：三星A10
操作系统版本：安卓9
Klarna 应用内 SDK 版本：com.klarna.mobile:sdk:2.0.16
