棉花糖上本机WebView中的Instagram链接 [英] Instagram-Links in native WebView on Marshmallow

问题描述

最近，我注意到当您尝试调用 https://www.instragram.com时，出现了一个非常奇怪的错误. /在您的智能手机运行 Android 6棉花糖时在网络视图中.

Recently I noticed a really strange bug that appears, when you try to call https://www.instragram.com/ in a webview when your smartphone runs Android 6 Marshmallow.

问题是，屏幕始终保持空白，只是中间有一个小instagram图标-看起来像是正在加载的屏幕.看起来像这样:

The problem is, that the screen remains blank all the time, just with that little instagram-icon in the middle - kind of a loading screen it seems. It looks like this:

当您在未启用JavaScript的情况下在浏览器中查看Instagram页面时，也会发生这种情况-如果没有JavaScript，该页面似乎无法加载.奇怪的是，我在网络视图中做了以下设置:

This also happens when you view Instagram pages in your browser without having JavaScript enabled - it seems like the page does not load without JavaScript. The strange thing is, that I did the following setttings in my webview:

 WV_Downloader.getSettings().setJavaScriptEnabled(true);
 WV_Downloader.getSettings().setDomStorageEnabled(true);
 WV_Downloader.getSettings().setBlockNetworkImage(false);
 WV_Downloader.getSettings().setLoadsImagesAutomatically(true);

在更高版本的Android上，它可以完美运行，为什么它不能在Android 6上运行?没有错误日志，只有一些正常的铬输出(我认为)不会导致这样的行为:

On later Android versions it works perfectly, why doesn't it work on Android 6? There are no error-logs, just some normal chromium-outputs that (I think) wouldn't cause a behaviour like this:

I/chromium: [INFO:CONSOLE(0)] "Unrecognized Content-Security-Policy directive 'worker-src'."
I/chromium: [INFO:CONSOLE(16)] "The key "viewport-fit" is not recognized and ignored."
I/chromium: [INFO:CONSOLE(1)] "Uncaught TypeError: Cannot read property 'entry_data' of undefined"
W/chromium: [WARNING:keycode_converter.cc(91)] empty code string
I/chromium: [INFO:CONSOLE(0)] "The source list for Content Security Policy directive 'script-src' contains an invalid source: ''report-sample''. It will be ignored."
I/chromium: [INFO:CONSOLE(0)] "The source list for Content Security Policy directive 'script-src' contains an invalid source: ''strict-dynamic''. It will be ignored."
I/chromium: [INFO:CONSOLE(0)] "Unrecognized Content-Security-Policy directive 'worker-src'.

我在互联网上找不到这种行为的解释.有人可以解释一下，这可能是什么原因?预先感谢！

I couldn't find an explanation for this behaviour on the internet. Can someone explain me, what could be the reason for this? Thanks in advance!
