webview

问题 I am working on a webView in an app, where content which webview load changes when a button is pressed (two buttons next and previous , they just change the content in webview). But after pressing 3 -4 times it starts to hang there is nothing printed on logcat, the button remains pressed for 15-20 sec and then the next data is loaded. I have used these to clear out webview.db and cache:- context.this.deleteDatabase("webview.db"); context.this.deleteDatabase("webviewCache.db"); webView

问题 So an android browser or a webview works fine with urls like this - abc.com/xyz.txt However, if your URL looks like this - abc.com/xyz.php and what's sent to the browser in the headers is - Content-Disposition: attachment; filename="xyz.txt", then the Android browsers and web view seems to get terribly confused. It looks like it saves the correct file name on the phone, but the contents is filled with the webpage that was previously being viewed. This works perfectly well on PC based browsers

问题 I have created a webView: videoView.delegate = self; videoView.userInteractionEnabled = true; [videoView loadRequest:[[NSURLRequest alloc]initWithURL:[[NSURL alloc] initWithString:@"website"]]]; I have html/javascript to handle the video's loading as well as the autoplay and next video. This all works, but my problem is that IOS autoloads the quicktime - like player, which is also a good thing, but I do not know how to control that, nor do I know how to get the video to play once that has

问题 I am currently working on an android app. This app consists of a WebView and displays a website which I don't own. (F.e. a WebStore) The app is supposed to recognize/detect when a user clicks a specific button on this website (f.e a "Buy Product" button). If a user clicks such a button, then the app makes a toast pop up. I know this will be different for every website, however how would I program the click detection in general? I read a few articles about injecting JavaScript etc, however I

问题 While this has been asked several times, the only question that really relates to my issue is this (Can I use shouldInterceptRequest to block a particular call in Android?), but it was asked more than 3 years ago and eventually got no replies. The request I'm trying to block is a POST request, so the shouldOverrideUrlLoading method is unable to intercept it. After a button is clicked, the webview loads an URL that contains the following string: "androidBundleId_********". I need to block this
