Android :: Web Page Not Available Error - Javascript Enabled
Feb 6, 2010
HelloWebview code (and other WebView code samples) all result in "web page not available" error. Javascript is enabled. Permissions set for INTERNET, ACCESS_NETWORK_STATE, CHANGE_NETWORK_STATE in Manifest.xml. Does not work on either emulator or device (Samsung Moment -- Android 1.5). GOOGLE.com comes up on both emulator and device. I have looked for s solution for this for several days. I'm a real newbie to Android, and a pretty new user of JAVA but can follow an example / sample.

I am very new to both android webkit and javascript. I have a web page with 3 links (say A,B,C). When I open that page on my PC browser(Chrome), and click on the links, A opens in the same browser window whereas B and C pops up a new window. In my application I am loading the original URL in a WebView. I have implemented my WebViewClient and overridden the shouldOverrideUrlLoading. I am getting the call to shouldOverrideUrlLoading whenever I click on A, but not getting it when I click on B or C?

I am about to develop a web application for smart phones. This app uses some JavaScript code. While testing it on Android devices (Hero, Desire) I noticed that all JavaScript timers immediately stop when the page is moved or zoomed. They never continue. Let's say you have a site which displays web camera images with 5 fps. As soon as you move this page (I mean scroll with finger) the web camera image will never be loaded again. So you can't center or zoom the image at all without stopping the stream. This behaviour is 100% reproducible on all Android devices I tested (1.5, 2.1). It does not appear on an iPhone which continues execution after moving stopped fine.

I installed the wireless tethering app today and decided to play with it for the heck of it, I was able to set it up, and when I went to my laptop and hit refresh I was able to see the network, I then tried to connect and it would not connect, as it said something about a 13 key ascii so I checked to see and checked the password and still could not connect got the same error message, i then decided to disable the encryption and then refresh the network and tried to connect again, I was able to connect but was not able to open a page up, now i don't know if that was because my reception was not great but still would not open a web page, any suggestions, another note, it rebooted the phone about 3 times and froze the phone once, I am on the AOSP Mod ROM V 0.9.7. I know the Cat mentioned he got his to work, just curious if it was with this Rom or the CM6 one, any input would be great, just want it as a backup incase of in a bind.

I have built a website for mobile webkit browsers, there is an interval update to refresh data. But it turns out that the pooling refresh will stop at some time after run for a while (some minutes or hours, different by each time).I thought there may be something error occurred in my refresh data functions, but it works well in my laptop browser. I also tried to listen window.onerror event, but webkit browser seems do not support that event. What else can I do?And I am also doubting is there any problem with setTimeout and setInterval functions in mobile webkit browser?

Ever since I've had my HTC Hero, the internet connection has been really flaky. That is, about half the time it works ok, but with a slow start, and the other half it doesn't work at all, and comes up with either a "cannot find page" in the browser, or "a network error has occurred" in Market or other apps.
I bought into the Hero thing because I wanted a mobile internet device and my iPhone wasn't cutting it with the lack of Flash. But at least my iPhone always worked!
The problem I'm having is this:
No matter whether I'm on wifi or not, browsing for a webpage in any of the available browsers (standard, steel, dolphin), has a delay of about 5 seconds, and then either starts loading the page, or comes up with some kind of "page not found" error. This happens with all websites, including the home page of google, which isn't exactly big or unreliable, except on my Hero.
Also, any app that uses an internet connection, such as Market, more often than not comes up with "a network error has occurred". Clicking "retry" rarely works.
Now if it was just through wifi, I would think it might be the setup of the routers that I've tried it on, allthough I've tried it on 3 completely different types of router, all with same symptoms.
I've also done much testing with wifi switched off, and still the same issues.
I could understand it if it just didn't work ever under either wifi or other, but sometimes it works, and sometimes it doesn't.
I have done my wifi tests while sitting right next to the routers, with maximum signal reception being indicated.
Ok, so it tells me that "a network error has occurred". Is there some way of finding out exactly what the error was? Was it a timeout, or a DNS error, or what?

I have the tronsmart CX-919 mini pc running 4.2 and there is an issue with the browser reverting back to the home page or the previous page. When I try to display a webpage on our intranet it reverts back to the homepage or previous page after about 3 hours. I need it to display constantly. I read somewhere that it was a Download Manager issue and disabling it would work but I can't find where to disable it. Also it was stated that Flash was an issue but i tried uninstalling it and it just reinstalled itself and the problem kept occurring. I just want to display a page in a browser and for it to stay on the screen (full screen) until I manually navigate away from it. I plan to leave it on for weeks at a time.

how do you paste copied text (ie a URL) from a web page into a new window to open that page?
Also can you restrict internet connection to 3g or 2 g only?
I've just come from n900 so trying to figure out the differences!

I did a quick search and didn't see this tip, but I just accidentally discovered that if you hit the volume key up or down it will scroll the browser page up or down respectively....just thought i would throw that out there in case no one knew..

Why is it every time I go to the internet, the last page viewed shows? I have my home page set to "Google." Shouldn't Google be the page that shows up? Also, it seems to save the history, even after I delete history, cookies, caches. Why? I was told to try and keep this, as well as deleted email, empty or the phone may become slow.

I am going to develop an app runs on both Android and desktop, so UI will be built on html , javascript, css. User experience is very important, I am looking for a javascript UI framework has great UI, animation and response time. A great UI framework but slow (cause user annoying) is not acceptable in my case.There are many javascript frameworks available. Can you guys share the experience of how they behave on Android ？

I'm loading up a webview with some locally generated html and javascript.It makes calls to app methods just fine.But what's the right way to get data from Javascript back to the application? It's simple to have javascript call app methods, but any parameters specified in the call on the javascript side don't survive the trip (I just get null in the app).Gross hacks seem obvious (open a url and encode the data in the url), but that can't be right.You received this message because you are subscribed to the Google Groups "Android Developers" group.

I'd like to call a JavaScript function out of Java.
Well, the following source code works fine for me (http:// whyandroid.com/android/206-using-webviews.html):
This is not called on the UI thread. Post a runnable to invoke
CODE:............
My problem now is to use a parameter for the JavaScript function.
Let's assume I've got some XML (just like AJAX somehow).
I need to escape it just like the iPhone / Objective-C command stringByEvaluatingJavaScriptFromString does.

I'm debugging a Javascript+HTML app. All the content is in ./assets.
The app works fine in Firefox, Safari and iPhone (over the web).
But in the WebView, I only get: D/WebCore (626): Console: undefined line: 0 source: undefined
I need to debug this code. Could I either: - enable more debugging in the WebView? though I think this needs to be done in the framework. or: - set up a desktop WebView equivalent where I can run a Javascript debugging tool?
