Android :: Webview Loadurl Cannot Load Webpage From Localhost Web Application?
Sep 1, 2010
I came across an interesting issue when testing android 2.2.
My testing was to use webview api,webview.loadUrl(url);
If url is from any public domain, ex, www.google.com, the web content is rendered very well.
[url]
If url is from local host, ex, tomcat with port 8080, the web content is rendered as well.
[url]
But if url is from other port, ex, websphere with port 9080, the web content is not rendered.
[url]
There is no exception thrown, and it shows blank on the emulator.
Is there any setting needed for different port?

I am wondering how does webview load a particular URL. Does it create a new thread or load the URL in the same thread i.e. UI thread? The reason I am asking this is I am facing some weird wakeup lock issue when I launch an Activity from current Activity (in current Activity's onCreate method) which creates a WebView in it's onCreate method and loads a URL using loadUrl method. So when I am done with this activity and go back to the Activity which launched this is restarted because wakeup lock time was expired.I googled it and found out that if onCreate method of an Activity takes too long then this type of issue might occur. Have any of you faced this kind of issue involving a WebView? Any kind of help would be really appreciated.
Here is sample code.Activity A:

I've come across a peculiar problem in one of my apps recently. I have a WebView that pulls down a webpage using loadUri(). This is being loaded into an activity that has just the WebView and a Button below the WebView inside a RelativeLayout. It works fine in the emulator on Android 1.6, 2.1, and 2.2. However, it does not show the webpage in Android 1.5. To strip things down to a bare minimum,
I used the following code from the API docs and tested it with similar results:
CODE:...........
Any thoughts as to what might be v1.5 specific that would cause this to not work? Am I missing something here?

I have a locally stored webpage (html) under res/raw folder.There is an image that is referenced in this html page (test.gif) which is stored under res/drawables.When I use a webview to display this page, it does not display the image. How can I correctly reference the path to the test.gif image?I tried using a text view with Html.fromHtml() but that does not parse several html tags.

I am loading a webpage using WebView.. my code looks like this..
Code:
public void open() {
myWebViewV = new WebView(this);
setContentView(myWebViewV);
myWebViewV.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
view.loadUrl(url);
return true;
} });
myWebViewV.loadUrl("http://www.mywebsite.org");
}
what this simple code does is load the website that I want to view.. fine..
But this site also has things like "Reply", "Register", "Login" and etc..
I'm trying to change it so that the user has to click the buttons that I create for him/her that will do basically the same thing.

Well, I'm trying to follow the tutorial from http://rapidandroid.org/wiki/Graphing. But I found a problem just in the first part of it. I'll describe the problem here, I just cannot understand how this could be wrong, it's pretty simple stuff. What am I doing wrong here? First I created a xml file called statistics.xml, in it among other things I put this code...
The problem arises here, as I seem to be getting null for wv whenever I test for it. Which means of course that findViewById(R.id.webview) couldn't find the view. But again, what am I doing wrong? Of course I know I could also instantiate the webview directly from code without the need to specify it from the xml, but I was just wondering what was wrong about this way of doing it. Just in case I also added the following line in my android manifest file.

I'm having problems with this. If I go to an SWF directly in the browser, it works fine. If I attempt to use loadUrl on an SWF file it stays blank and loads nothing.

I have an instance of Bitmap that I want to load into the WebView. How can I do this? I do not want to call webview.loadUrl() as the image is already loaded from the file into memory . I am trying to optimize my code. I can see webview.loadData() however, seems like I have to encode Bitmap into UTF-8?? I have two questions: 1) How can I use webview.loadData() from a Bitmap instance?

Is there any way I can load a URL without actually having the user see the web page? I'm trying to make a game with a hi score table, and loading the hi score URL in the browser would reveal the mechanism and allow the hi scores to be easily hacked. I have a php file on my server that my application is supposed to load to submit the hi score.

What i want is when first time application runs then it should show only image in the full screen and one progress bar. And in the background there should be a url like http://www.google.com should be loaded in WebView. Once the url loads fully then my first screen which contains progress bar and image should move away and new screen with loaded url comes up. Is it possible to load the url in the webview as a background and once loaded then only webview should appear.

My app uses a WebView widget to load ads from Google AdManager. AdManager gives you an HTML snippet, which is 90% javascript to call their server for the image to load.
I put their html snippet into a string and use String.format to add in several variables that AdManager requires.
I enable javascript on the WebView (webView.getSettings().setJavaScriptEnabled(true);)
I load the string into the WebView (webView.loadData(myString, "text/html", "UTF-8");
result: the ad never loads (although the WebViewClient shows serveral .js resources loading).
If I take that exact string and create a file and then use webView.loadUrl("file:///android_asset/test.html"), the image loads properly.
Why would loadUrl work but loadData does not?
I've verified that javascript is running. I injected a little script to write out a text string and it works.

In my app I have to load external page into WebView-based activity. Some of my users with slower connections are reporting screen timeout while waiting for the page to load. What would be a good way of loading the page on backgorund thread and then refreshing the screen? Use HttpClient to fetch it and then use WebView#loadData? My fear is - the page I'm loading is pretty complicated there's some JS that happens on load - wouldn't I just mess it up? Is there an alternative way of doing what I need?

I'm trying to load https requests with a Webkit object but It shows only a blank page, with http requests I don't have problems, It shows the page correctly. I have look the source code of the browser, in http://android.git.kernel.org/?p=platform/packages/apps/Browser.git;a... but I don't understand how the browser process the https requests. I think that the class BrowserActivity process the http and https requests but I don't see how to do it. Somebody could explain how the browser process the https request? It uses a Webview object to show the response of the https requests?

I have a web page that uses a custom font, using this CSS piece of code: If I load the page in the browser in Android 1.1, 1.5 or 1.6, this technique works fine, the font is downloaded and used. But these were the good times. Now this is all gone. With 2.0 my declaration is ignored, the default font is used, and I'm sad! This is in the Browser app, and in my app that uses a WebView.

I have a WebView on my Android application which loads (WebView.loadUrl()) different local HTML files from phone's internal storage. I would like to include some custom css styles for them, Now, I could have my app edit every HTML file and add linking reference for the CSS file.I could also read the file contents, add the CSS linking and use WebView.loadData() to load it.But is it possible to do this a lot simpler and efficiently.Note: The HTML files are downloaded from a website. So editing them manually is not possible in this case, but once downloaded they can be edited via the app if necessary.
