Active Oldest Votes. Late response here, but this is only half true; Dedicated Workers are available in Chrome Mobile, Shared Workers are not. Another twist is that although 'SharedWorker' in window does return true, and defining a path does make a request for the file, the messaging seems to be stubbed.

Post as a guest Name. Email Required, but never shown.If you want to deliver a web application or just a web page as a part of a client application, you can do it using WebView. The WebView class is an extension of Android's View class that allows you to display web pages as a part of your activity layout. It does not include any features of a fully developed web browser, such as navigation controls or an address bar.

All that WebView does, by default, is show a web page. A common scenario in which using WebView is helpful is when you want to provide information in your app that you might need to update, such as an end-user agreement or a user guide.

Within your Android app, you can create an Activity that contains a WebViewthen use that to display your document that's hosted online.

Another scenario in which WebView can help is if your app provides data to the user that always requires an Internet connection to retrieve data, such as email. In this case, you might find that it's easier to build a WebView in your Android app that shows a web page with all the user data, rather than performing a network request, then parsing the data and rendering it in an Android layout.

Instead, you can design a web page that's tailored for Android devices and then implement a WebView in your Android app that loads the web page. This document shows you how to get started with WebView and how to do some additional things, such as handle page navigation and bind JavaScript from your web page to client-side code in your Android app.

To add a WebView to your app in the layout, add the following code to your activity's layout XML file:. To load a web page in the WebViewuse loadUrl. For example:. Before this works, however, your app must have access to the Internet. That's all you need for a basic WebView that displays a web page. Additionally, you can customize your WebView by modifying the following:.

To safely use more-recent WebView capabilities on the device your app is running on, add AndroidX Webkit. The androidx. Once JavaScript is enabled, you can also create interfaces between your app code and your JavaScript code. JavaScript is disabled in a WebView by default. You can enable it through the WebSettings attached to your WebView.

WebSettings provides access to a variety of other settings that you might find useful. For example, if you're developing a web application that's designed specifically for the WebView in your Android app, then you can define a custom user agent string with setUserAgentStringthen query the custom user agent in your web page to verify that the client requesting your web page is actually your Android app.

When developing a web application that's designed specifically for the WebView in your Android app, you can create interfaces between your JavaScript code and client-side Android code.

For example, your JavaScript code can call a method in your Android code to display a Dialoginstead of using JavaScript's alert function. To bind a new interface between your JavaScript and Android code, call addJavascriptInterfacepassing it a class instance to bind to your JavaScript and an interface name that your JavaScript can call to access the class.

OffscreenCanvas

Caution: If you've set your targetSdkVersion to 17 or higher, you must add the JavascriptInterface annotation to any method that you want available to your JavaScript, and the method must be public. If you do not provide the annotation, the method is not accessible by your web page when running on Android 4. In this example, the WebAppInterface class allows the web page to create a Toast message, using the showToast method.

At this point, your web application has access to the WebAppInterface class.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
