TextView can render simple formatting like styles bold, italic, etc.

However, when it comes to complex formatting and larger scope in terms of HTML, then TextView fails to handle it well. WebView can also assist with common browsing metaphors, such as history list of visited URLs to support backwards and forwards navigation. Before we start toying around with the url there are two critical aspects we should take a look at:. The default behavior when a user clicks on a link inside the webpage is to open the systems default browser app.

This can break the user experience of the app users. When the shouldOverrideUrlLoading method returns false, the URLs passed as parameter to the method is loaded inside the WebView instead of the browser.

To distinguish between the URLs that are loaded within the app and browser the following code needs to be added in the shouldOverrideUrlLoading method:. To load the url into the browser an intent needs to fired.

To go through the browsing history on pressing back button we need to modify the back button function as shown in the snippet below:. The onKeyDown method has been overridden with an implementation that first checks if the WebView can go back. If the user has navigated away from the first page loaded inside the WebView, then the WebView can go back.

The WebView maintains a browsing history just like a normal browser. If there is no history then it will result in the default behavior of back button i. Below image shows the output produced by our project, you can see that WebView is loaded with a preassigned url. There are two flavors of loadData.

For Android versions before KitKat, the private methods mentioned in the other answers work. I have not found a good workaround for KitKat 4. This solution also works for Honeycomb and Ice Cream Sandwich. Seems like Google introduced a cool new feature accept attribute and forgot to to implement an overload for backwards compatibility.

Then I followed Michel Olivier's solution. Ive actually managed to get the file picker to appear in Kitkat, to select a image and to get the filepath in activity result but the only thing that im not able to "fix" cause this workaround is to make the input filed to fill out with file data.

By default, a WebView provides no browser-like widgets, does not enable JavaScript and web page errors are ignored.

If you actually want a full-blown web browser, then you probably want to invoke the Browser application with a URL Intent rather than show it with a WebView. I researched on this issue for almost one month.
