Android :: Formatting WebView Content (Text Display)

Mar 12, 2010

I am getting some HTML text from a remote server which I am displaying inside a WebView. I need to format the text display and set a font size and color for the WebView. The only way I can think of is: pre-pending the HTML string received with a tag and specify the font information there. What is the correct way to do this?

Android : WebView - Not Able To Go Back To My Activity Screen Once The Content Is Displayed

Apr 9, 2009

Step 1: I am subclassing WebView and rendering html content properly. The intial content is very small with a div and image /link This is displayed in a LInear Layout along with a TextView and ListView. That is my first screen/activity of the application.

Step 2: When I click on a link on this webview, it goes through the webViewclient and expands to full screen to fit the content of the requested page.

After Step 2, I am not able to go back to my activity screen once the content is displayed. When I click on the back button to getback to my activity screen close my activity and goes to the phone's applications desktop. (i.e goes out of my application).

Step 3: In order to fix this issue, I stopped setting my own subclasssed WebViewClient. After doing this, the it seems to render the clicked page in a webView as subactivity. Now When I click on backbutton, it goes back to the activity screen. But, the issue now is, I am not catch event when a link is clicked. How can I catch click events in this case.

Android :: Why Does Phone WebView Display A Black Screen

Dec 30, 2009

I've been banging my head against a wall this afternoon trying to get a WebView to work. Below is the code in the main class:

public class fkyougoogle extends Activity {
/** Called when the activity is first created. */
WebView webview;

public void onCreate(Bundle savedInstanceState) {

webview = (WebView) findViewById(;
//webview.loadData("<html><body>hello</body></html>", "text/html", "utf-8");
//webview.loadDataWithBaseURL("fake://", "<html><body>hello</body></html>", "text/html", "utf-8", "");}}

This is Google's "Hello, Webview" example. If I use a WebView and try to access then it works fine. If I try to access any other site then it fails including loadData and it just displays a black screen in the emulator. In the end I would like to read from a local file.

is included under the manifest tag and the XML schema is the same as the Hello Webview example.

Am I missing something obvious here?

Android :: How To Mix External / Local Content In WebView?

Oct 12, 2009

I am trying to create a hybrid Android app which pulls HTML content from a web server and renders it in a WebView. However, I also want the external HTML to be able to reference images that are packaged within the android app. I realize that currently it is not possible to do something like <img src="file:///my_image.jpg" /> in the HTML. I have seen discussions of using the ContentProvider to create name spaces in the html, however all of these examples seem to assume that the actual html page is also on the device and tend to use WebView.loadData(). So, is there someway that it is possible to do this? The main goal is to package all the application images/css in the android app, but put the bulk of the application on an external server that returns the actual markup.

Android :: Any Listener For When WebView Displays Content?

Oct 31, 2010

Using WebViewClient and/or the WebChromeClient you can get a listener for when the page has loaded, however this is sometimes called before the WebView has any content in it, before it has displayed anything. What would be a efficient method for determining when the WebView has displayed it's content? When I load a page in a WebView, I want to set the scroll to a specific position. It seems that the scroll position cannot be set until the page is loaded and it has an actual content height. So, I have tried two different approaches to determining when the page has finished loading, onPageFinished() from the WebViewClient and also onProgressChanged() from the WebChromeClient.

Both of these tell me when the page has finished loading. However, the problem is that sometimes it is called before the page has been displayed and therefore the page has no height and the scroll call does nothing. I am trying to find a solid way to determine when the page is ready to be scrolled, i.e. when it has its content height. I imagine I could setup a checking loop after it finished loading to keep looking for when the height is available but that seemed like quite the hack. Hoping there is a cleaner way.

Android :: Way To Find Height Of HTML Content Displayed In A Webview?

Apr 8, 2009

My application generates an HTML file which needs to be displayed to the user . For this purpose I'm using the loadData() API provided by Webview. This HTML file is updated every 2 secs & the same is loaded again using loadData() to display the updated values. On reloading the file the Webview starts displaying again from the top of the file causing the user to always scroll down to the location where he previously was. This causes a very bad user experience. To overcome this issue an alternative that I could think of was to split the file to multiple files that can exactly fit in the the screen. For this I need to find the height of the HTML content that can loaded in a web view. From the WebView documentation I found that an API getContentHeight() is provided for this purpose. Although this method returns me 0 on the first attempt. On subsequent attempt it gives me the height of the page that was previously loaded.

Android :: Pause Flash Content In WebView When Activity Isn't Visible?

Aug 7, 2010

I am experimenting with using a WebView to display Flash content inside my activity. Everything is working pretty well, but when the user hits the home key to put the activity into the background, the Flash content keeps running (sound keeps playing, etc)

I have noticed that both the stock Android browser and Dolphin Browser seem to avoid this problem, and properly pause the Flash content when the browsing activity is put into the background.

Ideally I would like a solution that kills the WebView completely if the activity is finishing, but pauses it otherwise (basically copying the default behavior of the browser)

Here is a simple test I put together that loads a game on Kongregate which has some background music:


I took a look at the latest source for the stock browser, and it seems to be doing something similar (calling pauseTimers/resumeTimers), although I fear the code I have been looking at is out of date, because it is calling functions that don't seem to exist anymore.

I did verify that the call to pauseTimers is working by testing with a simple JavaScript setInterval which updates a counter. Is there something else obvious that I should be trying in regard to Window or View management?

The documentation for the mobile Flash player says:

Flash Player will also automatically pause SWF playback it is not in view or the foreground application, for example when a call is received or alarm goes off, to reduce CPU utilization, battery usage and memory usage.

This seems to be working perfectly in both the stock browser and Dolphin Browser, but not in my app. Any ideas/solutions would be greatly appreciated!

Update: Here is the function we ended up adding to our activity to get this to work. We call it with "onPause" in the activity's onPause function and "onResume" in the activity's onResume function:

Android : How To Display HTML Content?

Jan 23, 2009

I am working on an app where I would like to display HTML data to the user. The HTML includes CSS stylesheets and images (JPG and PNG), but no javascript and definitely no network access. The data is being read from a ZIP file on the sdcard. I initially assumed I could create a WebView and use that to display my HTML, but there seems to be no way to also pass in the style and image resources. Some posts I saw suggested creating a ContentProvider, but this has a few problems for me: a) security: I want to keep all the data inside this app. There's no need for a ContentProvider if I don't want other apps using the content, right? b) files: The ContentProvider's openFile() method returns a ParcelFileDescriptor, which can only be created from a Socket or a File. I have neither, I have an InputStream. So it seems there's no way to return the image and style data from a ContentProvider anyway.

Android :: How To Display An Image From SD Card In WebView

Jul 13, 2010

When I started to display an image from the SDCARD in WebView, I got errors like:
" Not allowed to load local resource: file://".
I�ve found a solution for this, and you don�t even have to care about ContentProviders�
Here�s an example:
/* Using WebView to display the full-screen image */
WebView full = (WebView)findViewById(;
/* Set up the Zoom controls */
FrameLayout mContentView = (FrameLayout) get Window().
final View zoom = this.full.getZoomControls();
mContentView.addView(zoom, ZOOM_PARAMS);
/* Create a new Html that contains the full-screen image */
String html = new String();
html = ("<html><center><img src=""+fileName+""></html>" );
/* Finally, display the content using WebView */
full.loadDataWithBaseURL("file:///sdcard/data/data/com.youproject.example "utf-8",
""); Hope you found it useful, let me know how it works for you!
