Android webview Cache The webview control is often used in projects. When an HTML page is loaded, the database and cache folders are generated under the/data/application package directory, as shown in: The requested URL record is saved in webviewcache. dB, and the URL content is saved in the webviewcache folder. For ease of understanding, next we will simulate

During the Android development process, you will encounter the need to display the Web page, or you need to use the WebView control to achieve an effect. I this period of time in the CSDN blog client, using WebView to display the content of the blog, one is because the analysis of the content of the blog is more difficult to match, and the effect is not ideal, an

For some of the more frequent pages, the client generally use the method of loading H5, this time will be used to webview, in use, not directly throw it a URL address so simple things, but also need some additional configuration.publicvoidsetWebViewClient(WebViewClient client) { checkThread(); mProvider.setWebViewClient(client);}对于WebView来说，WebViewClient是一个很重要的类，它会接收各种通知和请求，如果

thread. Therefore, there is a problem with the way that the UI thread calls the Glthread thread directly. Finally, the problem is resolved by sending runnable through glsurfaceview.queueevent to the glthread thread.It seems that the soft rendering of the fault-tolerant ability, a hardware acceleration, the bottom is more fragile.Conclusion: Be sure to figure out which is the UI thread and which is the glthread thread.Fill in several points of knowledge found in the process of finding a problem:

For example, the file System API is disabled, WebRTC hardware decoding, and so on. The following is the starting process:2. Corresponds to the following four functions in the above class diagram.

() event is still not triggered. Why? After analyzing the code line by line, the root cause of the problem is finally found: This is mainly because the following settings are made: webView.getSettings().setBuiltInZoomControls(true); This setting allows the webview control to support scaling. This scaling setting will also respond to the onTouch event, so it will overwrite our own onTouhc listener, causin

This article describes the Android programming implementation of WebView Full-screen playback method. Share to everyone for your reference, specific as follows: Recently because the project to use WebView load HTML5 video, start not full screen, did a long time to make! Then according to my understanding of how to achieve full screen bar. First write the layout file Activity_main.xml: Princi

Most users will use third-party browsers such as UC, which leads to abnormal authentication. I recently found a good idea when I tried oauth authentication on the iPhone, that is, do not use a browser with the system and embed a webview in your own program to comple
