THIS ANSWER ADDED LATER: So the problem is that Adobe’s Flash Player creates a SurfaceView inside the WebView and there is a delay between the SurfaceView appearing and the Flash engine bothering to draw anything. In that small gap the SurfaceView appears totally black. The solution I’ve found is to subclass WebView and add a … Read more
Through the UIWebView delegate call. You need to set your webViews delegate to the current controller, and conform to the UIWebViewDelegate protocol. When the webView finished loading the page func webViewDidFinishLoad(_ webView: UIWebView) will get called.
@Override protected void onScrollChanged(int l, int t, int oldl, int oldt) { int height = (int) Math.floor(this.getContentHeight() * this.getScale()); int webViewHeight = this.getMeasuredHeight(); if(this.getScrollY() + webViewHeight >= height){ Log.i(“THE END”, “reached”); } super.onScrollChanged(l, t, oldl, oldt); } This logic works fine for a webview.
I want to know that if there is some time before i can access my object Yes, I think there is a delay, because WebView.addJavascriptInterface will run in the WebView’s internal worker thread. Perhaps you’ve thought about this, and realized that WebView has to maintain at least one worker thread to do asynchronous network IO. … Read more

This can be handled by overrwriting onSaveInstanceState(Bundle outState) in your activity and calling saveState from the webview: @Override protected void onSaveInstanceState(Bundle outState) { webView.saveState(outState); super.onSaveInstanceState(outState); } Then recover this in your onCreate after the webview has been re-inflated of course: @Override public void onCreate(final Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.blah); WebView webview = (WebView)findViewById(R.id.webview); if (savedInstanceState … Read more

It appears to be a bug, more details here: https://groups.google.com/a/chromium.org/forum/#!topic/android-webview-dev/m0EtO3IXNn0 On N+ new ART logging appears to have been introduced letting app developers know about certain binary compatibility problems in their code. Unfortunately, this is triggering for some of the API-level guarded code in WebView. One example is “Failed resolution of: Landroid/webkit/RenderProcessGoneDetail;”, which is triggered … Read more
